ABSTRACT A comprehensive program of lifestyle modification induces loss of approximately 10% of initial weight in 16 to 26 weeks, as revealed by a review of recent randomized controlled trials, including the Diabetes Prevention Program. Long-term weight control is facilitated by continued patient-therapist contact, whether provided in person or by telephone, mail, or e-mail. High levels of physical activity and the consumption of low-calorie, portion-controlled meals, including liquid meal replacements, can also help maintain weight loss. Additional studies are needed of the effects of macronutrient content (e.g., low-fat vs. low-carbohydrate diets) on long-term changes in weight and health. Research also is needed on effective methods of providing comprehensive weight loss control to the millions of Americans who need it.

    ABSTRACT: While group interventions for weight management have been shown to be efficacious, adherence is often low, especially among men. This pilot study seeks to test whether group interventions using web-based group video conferencing (VC) technology is effective for weight loss. We adapted a 12-week curriculum based on the Diabetes Prevention Program, and delivered this intervention to a small group of men (BMI ≥30 kg/m(2)), using web-based group VC. Participants were randomized to intervention (n = 32) or delayed-intervention control group (n = 32). The intervention group lost 3.5 % (95 % CI 2.1 %, 4.9 %) of their initial body weight. Difference in mean weight loss was 3.2 kg (p = 0.0002) and mean BMI decrease was 1.0 kg/m(2) (p = 0.0010) between the two groups. Virtual small groups may be an effective means of allowing face-to-face group interaction, while overcoming some barriers to access.

    ABSTRACT: The effects on body composition and cardiovascular risk of functional meat products, within a balanced diet, were investigated in a randomized, double-blind, 10-week nutritional intervention. Fifty-four adults were distributed in three groups, consuming 600 g/week of a reference meat product (RP), optimized nutritional product-1 (ONP-1), lower in fat, or ONP-2, n-3 PUFA enriched. Measures were performed at baseline and the endpoint. All groups lost fat mass, being subjects on the ONP-2 group those with more fat loss (p = 0.042) compared to the other groups. Correlation analyses evidenced significant associations between alpha-linolenic acid (ALA) intake and plasma levels (p = 0.001), as well as between plasma levels and fat mass changes (p = 0.03). The inclusion of optimized meat products, with n-3 PUFA (Polyunsaturated fatty acids) and an improved nutritional profile may be a healthy strategy, as a functional food, within an isocalorically controlled diet. ALA consumption may play a role in body composition changes.

    ABSTRACT: We propose that highly processed foods share pharmacokinetic properties (e.g. concentrated dose, rapid rate of absorption) with drugs of abuse, due to the addition of fat and/or refined carbohydrates and the rapid rate the refined carbohydrates are absorbed into the system, indicated by glycemic load (GL). The current study provides preliminary evidence for the foods and food attributes implicated in addictive-like eating. Cross-sectional. University (Study One) and community (Study Two). 120 undergraduates participated in Study One and 384 participants recruited through Amazon MTurk participated in Study Two. In Study One, participants (n = 120) completed the Yale Food Addiction Scale (YFAS) followed by a forced-choice task to indicate which foods, out of 35 foods varying in nutritional composition, were most associated with addictive-like eating behaviors. Using the same 35 foods, Study Two utilized hierarchical linear modeling to investigate which food attributes (e.g., fat grams) were related to addictive-like eating behavior (at level one) and explored the influence of individual differences for this association (at level two). In Study One, processed foods, higher in fat and GL, were most frequently associated with addictive-like eating behaviors. In Study Two, processing was a large, positive predictor for whether a food was associated with problematic, addictive-like eating behaviors. BMI and YFAS symptom count were small-to-moderate, positive predictors for this association. In a separate model, fat and GL were large, positive predictors of problematic food ratings. YFAS symptom count was a small, positive predictor of the relationship between GL and food ratings. The current study provides preliminary evidence that not all foods are equally implicated in addictive-like eating behavior, and highly processed foods, which may share characteristics with drugs of abuse (e.g. high dose, rapid rate of absorption) appear to be particularly associated with "food addiction."
