Abstract— Data, information, and technology are improving
healthcare aspects such as fitness tracking, patient-doctor
communication, and access to health records, etc. Diet
management approaches based on a functional estimation
involve clinical and computer-supported methods that are
utilized in the strategy of treatment. Clinical methods such as
dietary records, 24-hour recall, and food frequency are common
in practice and majorly rely on a calorie-conscious intake, which
though with a cautionary proceeding works as expected, but
inherently lags a focus on the processing levels of the ingredients
such as the quantifiable content of natural or processed food.
Calories consumed from natural sources share contrast to
processed food. The exploration, hence, needs a hybrid
approach that combines the computer-supported systems to
build on a processed food proportion estimation methodology.
Emerging augmented reality technologies seamlessly merge
real-world environments with computer-supported perceptual
information have the potential to solve the problem enabling
user decision support through a unified schema of nutritional
information. This research presents (i) a blueprint for a unified
schema that merges clinical and computer-supported methods
that underlie the viable standard for a host of multi-point
chronic diet management applications, followed by (ii) a work-
in-progress outline of the essential function blocks, resources,
clinical considerations, and integrations that form a technology
stack for the estimation of processed and non-processed food
towards a clinical conscious diet intake.

I. INTRODUCTION
Diet management is an essential factor to lead a healthy
life. The growing knowledge and awareness towards the
effects of lifestyle, food choices, health and organ efficiency
have made people conscious of food and nutrition intake.
Thus, diet management and nutrition management have
gained enormous significance. Diet management is not just a
trend but an indispensable aspect in the health care sector.
Many people belonging to the vulnerable group in the
healthcare sector, such as older people, pregnant ladies, people
suffering from chronic diseases, etc. depend deeply on diet
monitoring. The authors covered chronic diseases and their
treatment and wellness and post-traumatic stress disorders
using emerging technologies [1]. In continuation to the work,
covering lifestyle-based diseases, the group require great
attention when it comes to diet management. Lifestyle
diseases share risk factors like prolonged exposure to three
modifiable behaviors including smoking, unhealthy diet, and
physical inactivity. Unmonitored consumption of processed
food can lead to heart disease, stroke, diabetes, obesity,
metabolic syndrome, chronic obstructive pulmonary disease,
some types of cancer and psychological disorders. The
combination of four healthy lifestyle factors – maintaining a
healthy weight, exercising regularly, eating a healthy diet, and
not smoking – appears to be associated with an 80% reduction
in the risk of developing the most common and deadly chronic
diseases [2]. The intake of fried food, oil, red meat and equally
important the quantity of processed or unprocessed material
increasingly become the agent of a segment of non-
communicable lifestyle-based diseases. Fig. 1 shows the
analysis of stakeholders in chronic disease diet management
usually done when a person is admitted to a hospital or is
under the supervision of medical personnel. The cycle
involves clinical monitoring of the diet by a dietician and
assigned physician, The monitoring needed is constant in the
case of vulnerable groups.

Thus, the self-monitoring method for diet management
becomes very important. Real-time object detection
techniques in recent years work as the core techniques of a lot
of vital applications, for example, facial feature detections [3].
Mobile object detection has further enlarged the scope for its
applications [4]. These recent technological innovations can
leverage both the advantages of AI in object detection and AR
in information presentation [5]. Such explorations are
iteratively developed for instance Virtual Reality Exposure

Therapy (VRET) is used as psychotherapy for phobias and
Post Traumatic Stress Disorder (PTSD) [16]. In VRET, a
patient is immersed in a programmed computer-generated
virtual environment that helps the person directly confront
feared situations or locations that may not be safe to encounter
in real life. There is strong evidence that shows that VRET is
useful for treating several different phobias and social anxiety.
The implementation, however, requires complex immersive
technology integration that necessitates the know-how of a
host of technologies. The use case however in case of diet
management is considerably narrow which can be attained
using a mobile application and hence does not considerably
add up to the operational costs as showcased through the scope
of this investigation. This research is organized into five
sections as follows. Section 2 presents the essential
background to understanding clinical approaches and
computer-supported approaches for chronic diet management.
Section 3 outlines a discussion on a blueprint for a unified
schema that merges clinical and computer-supported methods
that underlie the viable standard for a host of multi-point
chronic diet management applications. Section 4 describes the
methodology and the required functional blocks, resources,
integrations that effectively results in the processed food
estimation. Section 5, as the conclusion, presents the future
direction and the work in progress prototype design.
II. BACKGROUND
This section presents essential background related to
chronic diet management that is organized in two major
directions. Fig. 2 presents clinical approaches and computer-
supported two major approaches and methods along with
their functional classifications.
Fig. 2. Chronic diet management approaches.
Chronic diet management methods currently adopted by
medical practitioners in the clinical approaches are mostly
manual methods, for instance, Dietary Records (DR) useful
in obtaining detailed information about all foods and
beverages consumed over a one- or more-day period [6]. The
24-hour recall method consists of a structured questionnaire
that helps participants to recall the food and drinks consumed
in the previous day [7]. Food frequency is used to obtain
information on the frequency and, in some cases, the portion
size of food and beverage consumption over a specified
period, typically the previous month or year [8]. These
methods have been prevalent in the healthcare society for a
long time, but these methods have a scope of error. So, more
accurate and automatic methods for diet monitoring are being
investigated and developed to minimize the scope of human
error. Technological advancements in healthcare systems
have impacted the medical infrastructure holistically. Data,
information, and technology are improving healthcare
aspects such as planning in diet management, patient-doctor
communication, and access to health records.
Clinical methods majorly focus on a calorie-conscious
intake, which though with a cautionary proceeding works
greatly, but inherently lags a focus on the ingredients of the
consumed food. Another popular approach utilizes a popular
system to classify foods based on the quantifiable amount of
processed food. Food processing is a spectrum that ranges
from basic technologies like freezing or milling, to the
incorporation of additives that promote shelf stability or
increase palatability. The NOVA classification categorizes it
as unprocessed, processed culinary ingredients, processed
foods, and ultra-processed foods categories detailing the
degree to which a food is processed [9]. Generally,
emphasizing unprocessed or minimally processed foods in
the daily diet is optimal. Open and collaborative projects such
as Open Food Facts is a food product database that includes
ingredients, allergens, nutrition facts, and any other
information that can be found on product labels that can be
used on a commercial and non-commercial project, that
additionally provides Application Programming Interface
(API) for allowing developers to use this database in their
personalized programs to utilize the database [10]. The Siga
classification assigns food grades to ingredients based on the
degree of food processing. The Siga evaluation method works
by downgrading the ingredients and processes used in food
formulation [11]. ScanUp has created a database from the
area of its presence with the French food products,
aggregating nutritional and environmental indicators such as
nutri-score, degree of processing, eco-score to use this data to
inform consumers about the quality of their products via a
mobile application [12]. Simultaneously, assisting the food
manufacturers and distributors in their market knowledge and
innovation development by conducting studies.
However, the computer-supported methods have a data
aggregation problem. The mentioned methods have good
individual performance and are automated. The community,
in general, has seen increased adoption of medical sensors
that include blood pressure, electroencephalogram (EEG),
oxygen saturation, heart rate, magnetic field, temperature and
so on. The data generated with these individual sensors when
coupled with clinical approaches and the computer-supported
methods results in a hybrid approach that effectively merges
the qualities of both the approaches such as continuous
monitoring of the quantity and quality of the calories that are
consumed. Mobile object detection has broadened the scope
of its applications even further. An innovative augmented
reality object detection system that incorporates visual
Artificial Intelligence (AI) can take advantage of both the
advantages of AI in object detection and AR in information
presentation. This is attained through a unified schema that
merges clinical and computer-supported methods that
underlie the viable standard for a host of multi-point chronic
diet management applications. The consolidated diet
management approaches are tabulated and presented in Table
1 below. Additionally, the key characteristics of diet
management approaches are summarized.
