Abstract and Figures

Introduction: Metabolic syndrome is a major public health problem affecting at least 20% of the world’s adult population. Components of the metabolic syndrome include obesity, impaired glucose metabolism, hypertension and altered lipid profile. Currently, medical treatment relies on drugs. A major problem is that patients with long-standing disease are excessively medicated because of an increase in the number of symptoms over time. A few clinical studies indicate that low-carbohydrate diets, including the paleolithic as well as the ketogenic diet, may be beneficial in the treatment of conditions associated with the metabolic syndrome. Case Report: Herein, we present a case of patient with metabolic syndrome successfully treated with the paleolithic ketogenic diet. While on the diet the patient was able to discontinue eight medicines, lost weight, showed a continuous improvement in glucose parameters and her blood pressure normalized. Currently, the patient is on the paleolithic ketogenic diet for 22 months, free of symptoms and side effects. Conclusion: We conclude that the paleolithic ketogenic diet was safe, feasible and effective in the treatment of this patient with metabolic syndrome.

Successful treatment of a patient with obesity,
type 2 diabetes and hypertension with the paleolithic ketogenic
diet
Csaba Tóth, Zsóa Clemens
SUMMARY
Metabolic syndrome is made up of a cluster of conditions including obesity, impaired insulin
sensitivity, hypertension and altered lipid prole. These conditions are also considered as risk
factors for type 2 diabetes and cardiovascular disease. Occurrence of these conditions is on
the rise worldwide despite of the increasing number of drugs used. There is evidence from the
literature indicating that intervention with low carbohydrate diets, including the paleolithic diet,
may be benecial in the metabolic syndrome. Except for one study with the paleolithic diet
these investigations are short in duration. Another limitation is that they do not give clues how
to deal with medications patients are treated with. Third, in these studies the paleolithic diet
did not produce ketosis which may limit the clinical effectiveness. Here we present a case of
a patient with metabolic syndrome and excessively medicated. The patient shifted toward the
paleolithic ketogenic diet and was able to discontinue medication, lost weight and her glucose
parameters markedly improved. Her hypertension normalized. Currently she is on the diet
for 22 months and show good adherence as also conrmed by laboratory tests. She is free of
symptoms and no side-effects emerged. Previously we reported cases with epilepsy and type
1 diabetes successfully treated with the same diet. We suggest that a dietary intervention with
the paleolithic ketogenic diet may be a simple, feasible and cost-effective method in some
forms of chronic disorders in highly motivated patients.

INTRODUCTION
Obesity, type 2 diabetes and hypertension represent a
major health problem. These conditions are components
of the metabolic syndrome affecting every fifth adult
worldwide [1]. Although it is now acknowledged that
type 2 diabetes and hypertension mostly result from
lifestyle factors but medical treatment continues to rely
on drugs [2]. Symptoms of the metabolic syndrome
typically show up in mid-life but the number of co-
morbidities are increasing through later years. Typically,
symptoms are controlled with an increasing number of
drugs. In parallel side effects are also increasing and
are usually controlled with additional medications. It is
a vicious circle. Currently, a major proportion of elderly
in the western world is overmedicated [3]. In sharp
contrast with this diseases of civilization are virtually
absent in contemporary hunter-gatherer societies [4].
It is suggested that chronic diseases of civilization result
from an evolutionary mismatch between our ancient
and current diet [5]. It was also suggested that a return
to an evolutionary adapted diet may be beneficial for

health [5]. The paleolithic diet has previously been shown
to confer metabolic benefits in healthy as well as in
patients with metabolic syndrome [6–10]. Voegtlin, first
proponent of the human evolutionary diet, suggested
an animal fat-meat based diet as being evolutionary
adapted [11]. Recently, we reported successful treatment
of patients with epilepsy [12] and type 1 diabetes [13]
with the paleolithic ketogenic diet. The diet we refer to
as the paleolithic ketogenic diet is close to the meat-fat
based diet originally proposed by Voegtlin [11]. Herein,
we report on a patient with obesity, type 2 diabetes
and hypertension whose excessive medication could be
discontinued and clinical parameters associated with the
metabolic syndrome markedly improved.
CASE REPORT
Previous medical history
The patient’s previous medical history included
gallbladder surgery in 1987 due to choledocholithiasis
and chronic cholecystitis. Hyperglycemia and impaired
glucose tolerance was first demonstrated on 24 February
2004. Due to bloody stool Weber test was performed
on 25 August 2006 which showed positivity. Therefore,
colonoscopy was performed on 19 September 2006 which
indicated a 2-cm polyp in the sigmoid colon. Irrigoscopy
performed on 25 September 2006 confirmed the above
mentioned polyp and also indicated dilation of the colon
as well as sigmoid diverticulosis. The polyp was removed
on 6 November 2006. Histopathology from this specimen
showed tubulovillous adenocarcinoma in polyp (Grade 1).
Resection margins were negative. Gastroscopy performed
on 21 September 2006 indicated reflux esophagitis and
erosive gastritis. Gastroscopy follow-up, three years
later, on 26 January 2009 indicated reflux esophagitis
but no evidence of gastritis. A next gastroscopy follow-
up on 26 January 2011, showed reflux esophagitis and a
5-mm gastric polyp which was removed. Histopathology
from this sample showed no abnormalities. A subsequent
gastroscopy performed on 14 March 2013 showed reflux
esophagitis. Colonoscopy follow-up on 26 January 2007
demonstrated dilation of colon. Subsequent colonoscopy
examinations on 27 August 2007, 25 August 2008, 31
August 2009 and 15 April 2013 were able to examine
the colon until the transversus lienalis and showed no
alterations. A computed tomography (CT) colonography
on 27 April 2011 was negative too.
On 10 December 2009, she experienced pressing pain
behind the sternum. Echocardiography on 14 December
2009 showed impaired left ventricular diastolic function
as well as aortic and mitral insufficiency.
A routine ophthalmological examination on 01 June
2006 showed crossing phenomenon and hyperemic
macula, ocular signs of hypertonia and diabetes. Follow-
up ophthalmology examination on 20 May 2009 and
on 21 May 2010 showed angiopathy while follow-up
examinations on 18 May 2012 and 30 July 2013 indicated
angiopathy as well as retinopathy.
Medications
Due to elevated blood glucose parameters and
high blood pressure from 01 March 2005 onwards
the patient was treated with acarbose, ramipril and
hydrochlorothiazide. On 02 November 2006 pantoprazole
was added because of reflux esophagitis revealed by
gastroscopy. Due to increases in blood glucose from 23
August 2007, the patient was also taking metformin.
On 14 December 2009 bisoprolol was added because of
high blood pressure. Following the cardiological event
acetylsalicylic acid was prescribed on 15 April 2010. From
28 October 2010, the patient was prescribed amlodipine
due to high blood pressure. The number and the names
(active substance) of the medications taken through the
course of the disease and the associated 90-min glucose
are indicated in Figure 1.
Paleolithic ketogenic diet
We first met the 65-year-old female on 30 January
2013. She was overweight (BMI 37.1, height 160 cm, weight
95 kg), had high blood sugar and frequent high blood
pressure spikes despite antidiabetic and antihypertensive
medication. At this time her systolic blood pressure was
between 130 and 160 mmHg and diastolic blood pressure
between 70 and 85 mmHg. Her fasting glucose level was
between 144 and 162 mg/dL. Altogether she was taking
eight medicines. The patient was motivated in weight loss
and in the reduction of her medication. She was advised
to start the paleolithic ketogenic diet. She was suggested
a diet consisting of at least 70% animal-based food with
a fat : protein ratio of at least 2:1. Fat and red meats were
preferred over lean meats. Offals meat were encouraged
to ensure adequate intake of vitamins. No more than
30% of the diet was suggested as plant-derived food
including root vegetables and small amounts of fruit.
Dairy, cereals, grains, legumes, solanaceous vegetables,
plant oils (including coconut oil), artificial sweeteners
and foods with additives were not allowed. In addition
to the paleolithic ketogenic diet, she was taking 2000
IU of vitamin D3 for four months then it was stopped.
No other vitamin or mineral supplements were used.
Typical foods the patient was eating include broth, stew,
fried bacon, beef steak, stewed calf liver, braised pork
marrow, greaves. Vegetables consumed as garnish were
limited and typically included root vegetables, onion and
cabbage.
Upon diet commencement (on the third day of the
diet) all medications were stopped promptly except for
bisoprolol which was discontinued within two weeks.
The patient was controlled tightly during the first weeks
of the diet. In case of high blood pressure, she was
advised to take captopril, a short-acting antihypertensive.
Laboratory workup was performed regularly (eight
times during 22 months on the diet) in order to control
adherence to the diet and to give feedback to the patient
(Table 1). All urinary analyses were positive for ketones.
While on the paleolithic ketogenic diet blood glucose

level, 90-min glucose on the glucose tolerance test, HgA1c
and total cholesterol levels decreased as compared to
previous measurements. Triglyceride levels also dropped
markedly as well as inflammatory markers including
erythrocyte sedimentation rate. A statistical analysis
(t-test) comparing laboratory measures during the two
years of the paleolithic ketogenic diet and during the
previous nine years on a normal diet revealed a significant
decrease for HgA1c (p=0.02), cholesterol (p=0.01)
and triglyceride (p=0.003). Typically, the patient had
two meals a day. She tracked glucose levels daily both
preprandially and postprandially before and after the
first meal of the day. The patient reported to strictly
adhere to the diet insofar not consuming non-paleolithic
food at all. At the same time she admitted having some
difficulties with fruit restriction and reported that her
spikes in blood sugar (Figure 2) and blood pressure to
be associated with these events of excess fruit intake.
Nevertheless home monitoring of glucose showed a clear
decreasing trend both preprandially and postprandially
between February 2013 and June 2014 (Figure 2). Then
due to the normalization of blood glucose she measured
blood glucose levels only occasionally. While on the diet
she also reported a decreasing tendency in the frequency
of high blood pressure spikes. At the time of writing this
case report, she had no high blood pressure spike for
six months. Despite no vitamin D supplementation, her
winter time vitamin D level (on 05 March 2014) was in the
normal range (85 nmol/L). The patient did not perform
exercise while on the paleolithic diet.
Currently, she is on the diet for 22 months. While on
the diet her weight changed from 95 kg to 81 kg and she
is still losing weight. Her BMI changed from 37.1 to 31.6.
She reported increased physical fitness and to be free of
symptoms. The patient gave written informed consent for
publication of her case.
DISCUSSION
Recent clinical studies show that low-carbohydrate
diets including the paleolithic diet are beneficial in
conditions associated with the metabolic syndrome
[6–10]. In the current medical practice, patients with
metabolic syndrome are generally treated with numerous
drugs. Yet studies available on the paleolithic diet does
not give clues how to deal with preexisting medications
when shifting towards the paleolithic diet. Our experience
indicate that upon the shift towards the paleolithic
ketogenic diet most drugs become unnecessary and
should be discontinued [14].
Herein, we analyzed past medical history of a patient
with metabolic syndrome to reveal how her medication
might have contributed to the worsening of her disease
and how disease was influenced by the paleolithic
ketogenic diet.
This case represents a typical disease career of a patient
with metabolic syndrome. Her medical history included
elevated glucose parameters and hypertension initially
controlled with oral antidiabetics and antihypertensives
in 2005. Then with the emergence of new diagnostic
findings pantoprazole was added. Two years later
metformin was added to support glucose metabolism.
Nevertheless glucose control deteriorated again in
2011 following the addition of three new drugs. These
included bisoprolol, acetylsalicylic acid and amlodipine.
Bisoprolol and amlodipine, which belong to beta-blocker
and calcium channel blocker type antihypertensives,
respectively, are known for their effect to adversely affect
glucose metabolism [15, 16]. Glucose parameters further
deteriorated in 2012.
Current guidelines first advise lifestyle changes and
exercise to treat the metabolic syndrome and to induce
Figure 2: Glucose levels preprandially and postprandially while
on the paleolithic ketogenic diet between February 2013 and
June 2014. Due to normalized blood glucose levels later on the
patient measured blood glucose only occasionally.
Figure 1: Time course of 90-min glucose level in the glucose
tolerance test and the number as well as the names of the
medications (active substance) between 2004 and 2014. Note
that 90-min glucose levels first tended to decrease with the use
of oral antidiabetics. Then from 2011 90-min glucose levels
increased again. We attribute decreased glucose tolerance to
the use of bisoprolol and amlodipine drugs known for their
diabetogenic effect. From January 2013 the patient shifted
toward the paleolithic ketogenic diet and was able to discontinue
all eight medications. In parallel 90-min glucose levels returned
to normal.

weight loss [1]. Yet these dietary advices usually remain
without effect [17]. Also, overweight people are unable to
exert considerable physical activity. Therefore, patients
are prescribed medications. A main problem is that in
current medical practice each component of the metabolic
syndrome is treated separately even though targeting one
symptom by a drug may worsen another symptom also
associated with the metabolic syndrome. Therefore, the
number of drugs as well as side effects are increasing.
Our patient was overweight and was taking eight
medicines. When shifting towards the paleolithic
ketogenic diet she was able to discontinue all medications.
Her weight begin to decrease along with improving
glucose parameters and lowered blood pressure. Our
experience with patients on the paleolithic ketogenic diet
indicate that the use of antihypertensive drugs hinder
the normalization of glucose levels and weight loss [14].
Also, antihypertensive drugs become unnecessary since
the paleolithic ketogenic diet efficiently lowers high blood
pressure. In this case, antihypertensive drugs could be
discontinued because the patient had no atherosclerosis.
In those cases, with atherosclerosis antihypertensives
may be discontinued only within a longer time period. The
blood pressure lowering effect of the paleolithic ketogenic
diet is due to the fact that the paleolithic ketogenic diet
limits those food components which result in elevated
blood pressure. These components mainly include fruits
and foods with added fructose. Drop in blood pressure was
also reported in previous studies with the paleolithic diet
[6, 8]. Our experience with patients with hypertension
indicate that as compared to the paleolithic diet which
does not limit fruits and vegetables, the paleolithic
ketogenic diet more efficiently normalize blood pressure.
Given that in the paleolithic ketogenic diet carbohydrate
intake is strongly limited less insulin is required for
normoglycemia and therefore oral antidiabetics become
unnecessary.
While on the paleolithic ketogenic diet home
monitoring of glucose in our patient showed a decreasing
tendency both preprandially and postprandially.
Laboratory measurements also showed a decreasing
tendency in glucose parameters and triglyceride
normalized too. Total cholesterol and LDL cholesterol
tended to decrease while HDL cholesterol remained
relatively unchanged. Uric acid remained in the normal
range while on the paleolithic ketogenic diet. These
laboratory parameters are similar to those in our two
previous cases on the paleolithic ketogenic diet [12, 13].
All six urinary tests were positive for ketones indicating
a good adherence to the diet. The patient admitted to
occasionally exceed the advised limit for fruit. She also
linked excessed fruit intake to high blood pressure spikes
which is in accordance with literature data showing
high blood pressure to be associated with fructose [18].
Nevertheless our patient reported a decreasing tendency
of blood pressure across the 22 months.
Those patients who underwent gallbladder surgery are
advised against eating fatty foods and the ketogenic diet
too. Our patient, however, reported no gastrointestinal
side effects while on the paleolithic ketogenic diet. Of
note, her winter-time vitamin D level was normal in
spite of no vitamin D supplementation indicating that a
regular intake of offal, animal fat and meat may ensure
normal vitamin D status. Also, no signs of vitamin
or mineral deficiency emerged despite of the lack of
supplementation.
Currently, the patient is on the paleolithic ketogenic
diet for 22 months. No side effects emerged and she is
free of symptoms. She is resoluted to continue the diet.
CONCLUSION
The paleolithic ketogenic diet proved to be a safe,
feasible and effective therapy in this patient with
metabolic syndrome. Medications could be discontinued
and components of the metabolic syndrome improved
continuously. We used the paleolithic ketogenic diet in a
patient without a gallbladder indicating that, contrary to
the widely held notion, this organ is not a prerequisite for
maintaining a diet rich in animal fat. Neither vitamin nor
other supplements was used indicating the effectiveness
of the paleolithic ketogenic diet as a sole therapy.

... Importantly, the classic version of the ketogenic diet is known to be associated with low magnesium levels (22) one of the most well-known side-effects of the classic ketogenic diet. Our published cases (14)(15)(16)(17)(18)(19)(20)(21), along with our general experience, however, indicate that magnesium levels are normal on the paleolithic ketogenic diet. In order to quantify this clinical observation we performed a study in which we retrospectively assessed magnesium levels in relation to glycemic parameters in 45 patients with various diseases and five healthy subjects on the paleolithic ketogenic diet. ...

Magnesium plays an essential role in several enzymatic reactions. Its deficiency is known to be widespread and has been associated with a variety of pathological conditions characterized by chronic inflammation and/or oxidative stress. The connection between the metabolism of glucose and magnesium at the cell level is wellestablished. We hypothesize that magnesium deficiency in chronic conditions is primarily due to Western type carbohydrate based metabolism. In previous case studies we have shown that magnesium levels are normal on the paleolithic ketogenic diet. Here we assessed magnesium levels in a larger sample (n=50) to address whether the paleolithic ketogenic diet is able to ensure normal blood magnesium levels. Materials and Methods To assess magnesium levels in patients and healthy controls on the paleolithic ketogenic diet in a larger sample, we retrospectively analysed laboratory data obtained from 50 patients/subjects who were following the diet and were also not taking magnesium or other supplements. Correlation calculation was performed between magnesium and glucose levels. Results We found magnesium levels to be in the normal range in all but one patient/subject. There was a significant inverse correlation between glucose and magnesium levels. Discussion Our results indicate that the paleolithic ketogenic diet ensures normal magnesium levels in various pathological conditions as well as in healthy subjects. We believe that the high prevelance of magnesium deficiency reported earlier for a variety of chronic conditions is correlated with carbohydrate-based Western type nutrition rather than that of the chronic condition itself. We discuss underlying mechanisms. Keywords magnesium, paleolithic, ketogenic, glucose, glycated hemoglobin, diabetesn
... An increasing number of studies, as also reviewed by a recent metaanalysis [15], indicate metabolic benefits of the human evolutionary diet also known as the stone age diet [16] or paleolithic diet [17]. In recent years we have published a series of case studies where type 1 diabetes [18,19], type 2 diabetes [20], epilepsy [21,22], Gilbert's syndrome [23] and Crohn's disease [24] where was successfully treated by the paleolithic ketogenic diet, an animal fat-meat based diet. In our most recent case study we reported on halted progression of soft palate cancer for 20 months in a patient on the paleolithic ketogenic diet [25]. ...
... It is known that plant oils, grains and dairy, among their other possible negative effects, may promote inflammation [17]. On the contrary, the paleolithic ketogenic diet, which is based on animal fat, meat and offal, seems to have an anti-inflammatory effect, as also seen in our other patients on the same diet [18][19][20][21][22][23][24][25]. In addition, while the classical ketogenic diet is known to induce nutrient deficiencies [29], the paleolithic ketogenic diet seems to supply optimal amounts of micronutrients as shown by the absence of deficiency symptoms and the normalization of laboratory parameters including iron, magnesium and vitamin levels, and normal function of the liver, kidney and thyroid gland. ...

Background: Ketogenic diets have repeatedly been suggested for the treatment of cancer. Yet, only a few case studies have been published that reported long term benefits associated with such diets. Case report: Here we present a case where rectal cancer was treated with an animal fat-meat based diet, which we refer to as the paleolithic ketogenic diet. Upon diet initiation, the patient discontinued three medicines he had been taking because of hypertension and hyperuricemia. The patient initially received 6 weeks of radiation therapy. Thereafter the patient used the diet as a stand-alone therapy for 22.5 months. The patient was not taking any medicines or dietary supplements while on the diet. During the first five month of the diet therapy the patient exhibited excellent adherence which was paralleled by improving laboratory parameters including decreasing tumor marker levels and decreasing tumor size. The patient was in a constant ketosis during the entire follow-up. From the seventh month on, however, his adherence level was fluctuating with periods of worse adherence paralleled with negative changes in laboratory parameters. Although MRI imaging showed that there was no increase in the size of the tumor, 22 months after diagnosis onset the patient reported an alteration in bowel habits and that the bloody stool had returned. Because of the emergence of these symptoms, 24 months after diagnosis onset, rectal surgery was performed. Conclusion: With using the paleolithic ketogenic diet the patient was able to postpone surgery for two years. During the first five months, when the patient was strictly adhering to the diet, the tumor regressed. Thereafter, with incomplete dietary adherence, disease seemed to be stable but symptoms suggested progression for the last few months of the follow-up. Deviations from diet rules, even those not affecting ketosis, resulted in the progression of the disease.
... Thus far, we have published several case reports of patients successfully treated with the PKD. These include: type 2 (Tóth and Clemens, 2015a) and type 1 diabetes (Tóth and Clemens, 2014;2015b), Crohn's disease , Gilbert's syndrome (Tóth and Clemens, 2015c), epilepsy (Clemens et al., 2013(Clemens et al., , 2015; complete reversal of cervical intraepithelial neoplasia ; halted progression of soft palate cancer , regression of rectal cancer (Tóth and Clemens, 2017) and unexpectedly long survival with glioblastoma (Tóth et al., 2019). In 2017, we published a study with 50 patients on the PKD with 98% showing magnesium levels in the normal range, which is unexpected for a population with chronic diseases. ...

C-peptide is used as a measure of endogenous insulin production. Given that insulin and C-peptide are produced in equal amounts, C-peptide is typically used to differentiate between external and endogenously produced insulin in insulin-treated type 1 diabetes mellitus (T1DM). In a clinical setting, a decline in C-peptide is regarded as a loss of beta cell function. However, physiological conditions may also be associated with low C-peptide levels. The authors of this paper use a low-carbohydrate diet, the so-called paleolithic ketogenic diet (PKD), in the treatment of various conditions and observed that C-peptide is typically low on this diet. In order to characterize C-peptide levels on this diet, we designed a study to retrospectively assess C-peptide levels in 100 non-T1DM subjects. We found that 55% of the subjects had a C-peptide level below the standard reference range. C-peptide levels correlated with glucose levels. A significant correlation was found between C-peptide and age, with younger subjects having lower C-peptide levels. Males also showed lower C-peptide levels than females. Given the increasing number of patients using low-carbohydrate diets worldwide, physicians should be aware of laboratory correlates of low-carbohydrate diets, including low C-peptide levels, most importantly to prevent incorrect T1DM diagnosis.
... However, following a carbohydrate restricted dies has also been linked to adaptive health outcomes, such as sustained weight loss, improved physique, reduced hunger, improved mood and cognition, better digestion, improved biomarkers, and higher quality of life [15,16]. In addition, a growing number of case reports suggest that carbohydrate-restrictive diets consisting almost exclusively of animal-sourced foods are effective in managing and even reversing chronic health conditions, including obesity, type 1 and 2 diabetes, Crohn's disease, and epilepsy [17]. The underlying physiological mechanism hypothesized to explain the health-related benefits of carbohydrate reduction is nutritional ketosis [18]. ...

The adoption of carbohydrate-restrictive diets to improve health is increasing in popularity, but there is a dearth of research on individuals who choose to severely restrict or entirely exclude carbohydrates. The present study investigated the beliefs and experiences of individuals following a diet that severely limits, or entirely excludes, dietary carbohydrates, colloquially known as a ‘zero-carb’ diet, for at least 6 months. Zero-carb dieters (n = 170) recruited via a social networking site completed an online qualitative survey prompting them to discuss their motives, rationale, and experiences of following a low-carb diet. Transcripts of participants’ responses were analyzed using inductive thematic analysis. Results revealed that participants’ decision to follow a zero-carb diet was driven by health concerns and benefits. Participants expressed a strong social identity and belongingness to online zero-carb communities. Participants reported strong intentions to follow the diet indefinitely. Shortcomings of the diet centered on experienced stigma; lack of support from healthcare providers and significant others; limited access to, and high cost of, foods; and limited scientific data on the diet. Further research into the benefits and shortcomings of zero-carb diets across settings and populations is warranted, and guidelines for healthcare professionals on how to support individuals following a zero-carb diet are needed.
... One mechanism could be that avoidance of grains contributes to the "care" of a healthy and anti-inflammatory microbiome [24,59]. Indeed, avoidance of grains is an integral part of many anti-inflammatory and auto-immune protocols [60][61][62][63][64]. Jönsson et al. could show that a Paleolithic diet decreased CRP levels in pigs [65], and our patients also gradually decreased their CRP levels, indicating a reduction of lowgrade inflammation. ...

Evolutionary principles are rarely considered in clinical oncology. We here aimed to test the feasibility and effects of a dietary and physical activity intervention based on evolutionary considerations in an oncological setting. A total of 13 breast cancer patients referred to our clinic for curative radiotherapy were recruited for this pilot study. The women were supposed to undertake a "Paleolithic lifestyle" (PL) intervention consisting of a Paleolithic diet and daily outdoor activity of at least 30 min duration while undergoing radiotherapy. Body composition was measured weekly by bioimpedance analysis. Blood parameters were assessed before, during, and at the end of radiotherapy. A control group on an unspecified standard diet (SD) was assigned by propensity score matching. A total of eleven patients completed the study. The majority of patients (64%) reported feeling good or very good during the intervention. The intervention group experienced an average decrease of 0.4 kg body weight (p < 0.001) and 0.34 kg (p < 0.001) fat mass per week, but fat-free and skeletal muscle mass were not significantly affected. Vitamin D levels increased slightly from 23.8 (11-37.3) ng/ml to 25.1 (22.6-41.6) ng/ml (p = 0.053). β-hydroxybutyrate levels were significantly increased and triglycerides and free T3 hormone levels significantly reduced by the PL intervention. This pilot study shows that adoption of a PL intervention during curative radiotherapy of breast cancer patients is feasible and able to reduce fat mass. Daily outdoor activity could eliminate vitamin D deficiency (vitamin D < 20 ng/ml). Future studies are needed to confirm these findings.
... High-fat, low-carbohydrate and adequate-protein ketogenic diets (KD) was originally used for the treatment of epilepsy [9,10]. Recent studies revealed that KD can also be applied to the treatment of some metabolic or endocrine diseases such as obesity, diabetes and hypertension [11,12]. As we know, malignant tumors were also regarded as a metabolic disease due to their altered glucose metabolism, which was tumor cells preferentially utilize glycolysis instead of oxidative phosphorylation to generate energy and other metabolites [13]. ...

Background: High-fat, low-carbohydrate and adequate-protein ketogenic diets (KD) are expected to become an effective adjunct therapy for cancer patients. However, the direct effects of KD on tumor cells and the underlying mechanisms are elusive. In this study, the nude mouse models of subcutaneous transplanted human colon cancer cells were established and applied to study the effects and mechanisms of KD on the growth of subcutaneous tumors in nude mice. Methods: Male nude mice were injected subcutaneously with human colon cancer HCT-116 cell line to construct a subcutaneous tumor model of human colon cancer. The successfully constructed subcutaneous tumor mice were divided into normal diet group and KD group. The mice were anesthetized and euthanized after 30 days of feeding, the subcutaneous tumor tissues were collected, and the size of tumors was measured and weighed. HE staining was used to observe the pathological changes of subcutaneous tumor tissues in normal feeding group and KD group. TUNEL staining was used to detect the level of apoptosis in tumor tissue. Immunohistochemistry of subcutaneous tumor tissues was used to detect the expression levels of Wnt-1 and β-catenin. In addition, RT-qPCR and western blotting were applied to detect the expression levels of Wnt1/β-catenin signaling pathway-related proteins. Results: After 30 days of normal diet and KD feeding, the subcutaneous tumor tissues of human colon cancer mice were taken out for various assays. The results of tumor size measurement showed that the tumor size and weight of KD group were significantly smaller than that of the normal diet group. HE staining showed that the pathological characteristics of colon tumor tissue in the KD group were significantly improved, and the infiltration of inflammatory cells was reduced. TUNEL staining showed that the apoptosis level of tumor cells in the KD group was significantly increased compared to the normal diet group. RT-qPCR and western blotting revealed that the expression of pro-apoptotic proteins such as caspase 3,caspase 9 and Bax were increased(P < 0.01), while the expression of anti-apoptotic protein such as Bcl-2 or survivin was decreased (P < 0.01). Furthermore, the expression of Wnt1/β-catenin signaling pathway-related proteins including Wnt1 and β-catenin were largely reduced after 30 days of KD feeding compared to normal feeding group (P < 0.01). Conclusions: Ketogenic diets (KD) promotes apoptosis of human colon cancer subcutaneous tumor cells and inhibits the growth of tumor by inhibiting Wnt1/β-catenin signaling pathway in mouse subcutaneous tumor models of human colon cancer.
... Previously we have published a case of soft palate cancer halted by the paleolithic ketogenic diet for 20 months [10]. We also reported successful management of cases of autoimmune conditions including type 1 diabetes [24,25] and cases with epilepsy [26,27] and metabolic syndrome [28] using the paleolithic ketogenic diet. In another case study we reported that a full dietary adherence is needed to halt disease progression in rectal cancer [29]. ...

Background: Ketogenic diets have repeatedly been suggested for the treatment of cancer. To date, only a few case studies reporting long term benefits associated with such diets have been published. Case report: Here we present a case where recurrent cervical intraepithelial neoplasia (CIN), a premalignant condition of cervical cancer, was successfully treated with the paleolithic ketogenic diet. The patient had a history of high grade CIN in 2011, which was successfully treated with cervical conization and fractional curettage. In October 2015 she was found to have a recurrence of high grade CIN (HSIL: High Grade Squamous Intraepithelial Lesion). The patient was then commenced on the paleolithic ketogenic diet and her repeat Pap (Papanicolaou) smear three months later was found to have reverted to normal. The patient has remained on the paleolithic ketogenic diet for 26 months, her repeat smears have stayed normal, and she is free of symptoms and side effects. Conclusion: We conclude that the diet was effective and safe in this patient. As a major benefit the patient was able to avoid a hysterectomy, which is the standard treatment for recurrent high-grade CIN. We believe that the paleolithic ketogenic diet combines benefits of both paleolithic and classical ketogenic diets, while excluding their disadvantages.
... Erickson et al. [1] recently published a review on the use of the ketogenic diet in cancer. The authors of this reply are clinicians who bring into play an evolutionary approach in the practice of medicine and specifically have been using the paleolithic ketogenic diet in the treatment of chronic diseases since 2011 [2][3][4][5][6][7][8][9]. We have instituted the paleolithic ketogenic diet in approximately 4000 patients, of whom several hundred have been followed up for at least one year, and 60 cancer patients who have been followed up for at least 6 months. ...

Dyslipidemia is defined as an imbalance in the blood lipid profile that can cause many metabolic diseases. Several clinical studies in the past have proven the importance of a proper diet in the prevention and treatment of dyslipidemia. However, the relationship between consumption of a single food like red meat or whole grain with the occurrence of dyslipidemia has been well investigated. But considering the cumulative effect of food patterns can indicate a better image of the relationship between daily food intake and dyslipidemia. It has been proven that following diets like the dietary approach to stop hypertension (DASH) diet and the Mediterranean diet (MD) have been associated with a reduction in inflammatory and lipid markers. In recent years, a new diet based on observing the food pattern of the ancestors and early humans, called the Paleolithic diet (PD), has been researched. The PD is categorized as low-carbohydrate and high-fat diet. It is thought that through increasing ketone bodies and suppressing appetite, it reduces the incidence of metabolic diseases. Studies have also been conducted to find out the relationship between PD and dyslipidemia. Therefore, we decided to collect the results of some of them in this chapter.

Background: While predominant dietary guidelines promote foods low in fat and high in carbohydrates, evidence links high carbohydrate consumption to adverse health effects in populations that are metabolically challenged by (pre)diabetes or metabolic syndrome. An increasing number of people report eating diets that limit carbohydrates. These diets are known as low carb or ketogenic diets. There is emerging advocacy of a specific variant of a ketogenic diet, the zero-carb diet, which aims to severely limit, or even exclude entirely, carbohydrate consumption. However, little empirical research has been dedicated to exploring the determinants of zero-carb diets and the views of the people that follow them. Objective: This study aimed to investigate the perspectives and experiences of people following zero-carb diets for at least 6 months. The study also aimed to elicit the salient beliefs that shape uptake and adherence to the diet. Methods: Zero-carb dieters (N = 170) recruited from a social media platform completed an open-ended survey comprising questions on beliefs and motives of following a zero-carb diet. Participant responses were thematically analysed. Results: Participants were driven by health concerns to uptake the diet and adhered to the diet for its health benefits. Moreover, participants also expressed a strong social identity and belongingness to the zero-carb community. Challenges largely centred on social stigma, lack of support from health-care providers and significant others, limited access to, and high cost of, foods, and lack of empirical support for the diet. Despite these challenges, participants reported strong intentions to follow the diet indefinitely. Conclusions: We recommend further research into the health benefits of zero-carb diets across settings and populations, and into developing guidelines for healthcare professionals to support individuals wishing to follow zero-carb diets.

Introduction: Type 1 diabetes mellitus (T1DM) patients are usually instructed to follow a low fat/high carbohydrate diet. A few studies in literature, however, reported metabolic benefits and sustainability of carbohydrate restricted diets. Case Report: Herein, we present a case of a 19-year-old male with newly diagnosed T1DM. The patient was first put on an insulin regime. Twenty days later, he shifted towards the paleolithic ketogenic diet and was able to discontinue insulin. Strict adherence to the diet resulted in normal glucose levels and a more than three-fold elevation of C-peptide level indicating restored insulin production. Currently, the patient is on the paleolithic ketogenic diet for 6.5 months. He is free of complaints, and no side effects emerged. Conclusion: We conclude that the paleolithic ketogenic diet was effective and safe in the management of this case of newly diagnosed T1DM. Marked increase in C peptide level within two months indicates that the paleolithic ketogenic diet may halt or reverse autoimmune processes destructing pancreatic beta cell function in T1DM.

The main goal of this randomized controlled single-blinded pilot study was to study whether, independent of weight loss, a Palaeolithic-type diet alters characteristics of the metabolic syndrome. Next we searched for outcome variables that might become favourably influenced by a Paleolithic-type diet and may provide new insights in the pathophysiological mechanisms underlying the metabolic syndrome. In addition, more information on feasibility and designing an innovative dietary research program on the basis of a Palaeolithic-type diet was obtained. Thirty-four subjects, with at least two characteristics of the metabolic syndrome, were randomized to a two weeks Palaeolithic-type diet (n = 18) or an isoenergetic healthy reference diet, based on the guidelines of the Dutch Health Council (n = 14). Thirty-two subjects completed the study. Measures were taken to keep bodyweight stable. As primary outcomes oral glucose tolerance and characteristics of the metabolic syndrome (abdominal circumference, blood pressure, glucose, lipids) were measured. Secondary outcomes were intestinal permeability, inflammation and salivary cortisol. Data were collected at baseline and after the intervention. Subjects were 53.5 (SD9.7) year old men (n = 9) and women (n = 25) with mean BMI of 31.8 (SD5.7) kg/m2. The Palaeolithic-type diet resulted in lower systolic blood pressure (−9.1 mmHg; P = 0.015), diastolic blood pressure (−5.2 mmHg; P = 0.038), total cholesterol (−0.52 mmol/l; P = 0.037), triglycerides (−0.89 mmol/l; P = 0.001) and higher HDL-cholesterol (+0.15 mmol/l; P = 0.013), compared to reference. The number of characteristics of the metabolic syndrome decreased with 1.07 (P = 0.010) upon the Palaeolithic-type diet, compared to reference. Despite efforts to keep bodyweight stable, it decreased in the Palaeolithic group compared to reference (−1.32 kg; P = 0.012). However, favourable effects remained after post-hoc adjustments for this unintended weight loss. No changes were observed for intestinal permeability, inflammation and salivary cortisol. We conclude that consuming a Palaeolithic-type diet for two weeks improved several cardiovascular risk factors compared to a healthy reference diet in subjects with the metabolic syndrome.

Background/objectives: Short-term studies have suggested beneficial effects of a Palaeolithic-type diet (PD) on body weight and metabolic balance. We now report the long-term effects of a PD on anthropometric measurements and metabolic balance in obese postmenopausal women, in comparison with a diet according to the Nordic Nutrition Recommendations (NNR). Subjects/methods: Seventy obese postmenopausal women (mean age 60 years, body mass index 33 kg/m(2)) were assigned to an ad libitum PD or NNR diet in a 2-year randomized controlled trial. The primary outcome was change in fat mass as measured by dual-energy X-ray absorptiometry. Results: Both groups significantly decreased total fat mass at 6 months (-6.5 and-2.6 kg) and 24 months (-4.6 and-2.9 kg), with a more pronounced fat loss in the PD group at 6 months (P<0.001) but not at 24 months (P=0.095). Waist circumference and sagittal diameter also decreased in both the groups, with a more pronounced decrease in the PD group at 6 months (-11.1 vs-5.8 cm, P=0.001 and-3.7 vs-2.0 cm, P<0.001, respectively). Triglyceride levels decreased significantly more at 6 and 24 months in the PD group than in the NNR group (P<0.001 and P=0.004). Nitrogen excretion did not differ between the groups. Conclusions: A PD has greater beneficial effects vs an NNR diet regarding fat mass, abdominal obesity and triglyceride levels in obese postmenopausal women; effects not sustained for anthropometric measurements at 24 months. Adherence to protein intake was poor in the PD group. The long-term consequences of these changes remain to be studied.

Introduction Childhood absence epilepsy is an epilepsy syndrome responding relatively well to the ketogenic diet with one-third of patients becoming seizure-free. Less restrictive variants of the classical ketogenic diet, however, have been shown to confer similar benefits. Beneficial effects of high fat, low-carbohydrate diets are often explained in evolutionary terms. However, the paleolithic diet itself which advocates a return to the human evolutionary diet has not yet been studied in epilepsy. Results Here, we present a case of a 7-year-old child with absence epilepsy successfully treated with the paleolithic ketogenic diet alone. In addition to seizure freedom achieved within 6 weeks, developmental and behavioral improvements were noted. The child remained seizure-free when subsequently shifted toward a paleolithic diet. Conclusion It is concluded that the paleolithic ketogenic diet was effective, safe and feasible in the treatment of this case of childhood absence epilepsy.

Polypharmacotherapy is a major concern in the elderly and especially in older women after the age of 80. It results from the intake of prescription and non-prescription drugs, being often a problem of evidence-based therapy. Besides the fact that women live longer than men and outnumber them, reasons for polypharmacy in women are diverse and include a different attitude towards intake of drugs between men and women, the propensity of women to rather see a physician and talk about their problems, the load of family responsibility as women are the main caregivers within a family, the influence of physician sex on patient care, the level of education, social deprivation and self-rated health. Women are more often prescribed potentially inappropriate medication and more often become victims of adverse drug reactions. This is not only due to the number and quality of drugs prescribed but also to differences in pharmacokinetics and - dynamics which make them more vulnerable to drug exposure. Thus, inappropriate prescribing contributes to hospitalization, poor quality of life, costs, compliance issues and poor outcomes. More preclinical and clinical studies with elderly patients and especially elderly women are needed to study the underlying mechanisms of the pharmacologic differences and obtain more insight into the difference in risk between men and women. Attention to prescribing of medications, consistent review of medication lists, and reevaluation of indications and outcomes of prescribing are essential to ensure that drugs are used appropriately in elderly women, polypharmacy is minimized and safety for patients is maximized.

Our aim was to compare the effects of a Paleolithic ('Old Stone Age') diet and a diabetes diet as generally recommended on risk factors for cardiovascular disease in patients with type 2 diabetes not treated with insulin. In a randomized cross-over study, 13 patients with type 2 diabetes, 3 women and 10 men, were instructed to eat a Paleolithic diet based on lean meat, fish, fruits, vegetables, root vegetables, eggs and nuts; and a Diabetes diet designed in accordance with dietary guidelines during two consecutive 3-month periods. Outcome variables included changes in weight, waist circumference, serum lipids, C-reactive protein, blood pressure, glycated haemoglobin (HbA1c), and areas under the curve for plasma glucose and plasma insulin in the 75 g oral glucose tolerance test. Dietary intake was evaluated by use of 4-day weighed food records. Study participants had on average a diabetes duration of 9 years, a mean HbA1c of 6,6% units by Mono-S standard and were usually treated with metformin alone (3 subjects) or metformin in combination with a sulfonylurea (3 subjects) or a thiazolidinedione (3 subjects). Mean average dose of metformin was 1031 mg per day. Compared to the diabetes diet, the Paleolithic diet resulted in lower mean values of HbA1c (-0.4% units, p = 0.01), triacylglycerol (-0.4 mmol/L, p = 0.003), diastolic blood pressure (-4 mmHg, p = 0.03), weight (-3 kg, p = 0.01), BMI (-1 kg/m2, p = 0.04) and waist circumference (-4 cm, p = 0.02), and higher mean values of high density lipoprotein cholesterol (+0.08 mmol/L, p = 0.03). The Paleolithic diet was mainly lower in cereals and dairy products, and higher in fruits, vegetables, meat and eggs, as compared with the Diabetes diet. Further, the Paleolithic diet was lower in total energy, energy density, carbohydrate, dietary glycemic load, saturated fatty acids and calcium, and higher in unsaturated fatty acids, dietary cholesterol and several vitamins. Dietary GI was slightly lower in the Paleolithic diet (GI = 50) than in the Diabetic diet (GI = 55). Over a 3-month study period, a Paleolithic diet improved glycemic control and several cardiovascular risk factors compared to a Diabetes diet in patients with type 2 diabetes.

Abstract Current nutritional approaches to metabolic syndrome and type 2 diabetes generally rely on reductions in dietary fat. The success of such approaches has been limited and therapy more generally relies on pharmacology. The argument is made that a re-evaluation of the role of carbohydrate restriction, the historical and intuitive approach to the problem, may provide an alternative and possibly superior dietary strategy. The rationale is that carbohydrate restriction improves glycemic control and reduces insulin fluctuations which are primary targets. Experiments are summarized showing that carbohydrate-restricted diets are at least as effective for weight loss as low-fat diets and that substitution of fat for carbohydrate is generally beneficial for risk of cardiovascular disease. These beneficial effects of carbohydrate restriction do not require weight loss. Finally, the point is reiterated that carbohydrate restriction improves all of the features of metabolic syndrome.

Increased rates (if diabetes have been reported with thiazide diuretics and beta-blockers, but not with angiotensin-converting enzyme inhibitors, angiotensin receptor blockers or calcium channel blockers. These observations are important because significant glycemic effects of drugsmay be a source of accelerated cardiovascular risk that is not detectable during restricted clinical trial follow-up periods. The extent to Which diabetes is affected by these medications remains unclear, as is the precise mechanism by which diabetes is promoted. However, several plausible theories are presented herein. Although drug-induced diabetes has been a concern for several years, not enough is information is available to influence prescribing for the majority of patients. The number one priority should be controlling blood pressure in a timely manner.

Nutrition science is a highly fractionated, contentious field with rapidly changing viewpoints on both minor and major issues impacting on public health. With an evolutionary perspective as its basis, this exciting book provides a framework by which the discipline can finally be coherently explored. By looking at what we know of human evolution and disease in relation to the diets that humans enjoy now and prehistorically, the book allows the reader to begin to truly understand the link between diet and disease in the Western world and move towards a greater knowledge of what can be defined as the optimal human diet. Written by a leading expert Covers all major diseases, including cancer, heart disease, obesity, stroke and dementia Details the benefits and risks associated with the Palaeolithic diet Draws conclusions on key topics including sustainable nutrition and the question of healthy eating This important book provides an exciting and useful insight into this fascinating subject area and will be of great interest to nutritionists, dietitians and other members of the health professions. Evolutionary biologists and anthropologists will also find much of interest within the book. All university and research establishments where nutritional sciences, medicine, food science and biological sciences are studied and taught should have copies of this title.

The association between fructose and increased blood pressure is still incompletely defined, because experimental studies have produced dissimilar conclusions. Amplified vasopressor responses to minimal stimuli and differing responses to fructose in peripheral versus central sites may explain the controversy. Fructose induces systemic hypertension through several mechanisms mainly associated with deleterious effects on target organs (kidney, endothelium, heart) exerted by the byproducts of its metabolism, such as uric acid. The kidney is particularly sensitive to the effects of fructose because high loads of this sugar reach renal tissue. In addition, fructose increases reabsorption of salt and water in the small intestine and kidney; thus the combination of salt and fructose has a synergistic effect in the development of hypertension. Clinical and epidemiologic studies have also linked fructose consumption with hypertension. Further studies are warranted in order to understand the role of fructose in the development of hypertension.
