Abstract

fetched live from OpenAlex

This study aimed to explore changes in dietary intake and body composition in adults living with an overweight condition and obesity who participated in an 8-week meal kit delivery program that included tutorials on nutrition and eating behaviours. Thirty-four healthy adults (aged 18--65 y) classified as either overweight or obese (25 < body mass index [BMI] <40 kg/m2) were randomly (1:1:1) divided into three groups: Control, Nutrition, and Behaviour. At baseline and at 10-weeks, anthropometrics were measured and body composition was analyzed using dual energy x-ray absorptiometry. Participants recorded their food intake for three non-consecutive days at both time points, which was then analyzed for macronutrients, water consumption and fruit and vegetable intakes. Over the 8-weeks, meal-kits were delivered to all participants. Each week, the control (n = 11) received weekly handout of healthy eating and nutrition education, Nutrition (n = 11) had access to online tutorials about healthy eating and nutrition education and the Behaviour group had access to online eating behaviour tutorials. Repeated-measures, mixed model ANOVA were used to compare changes in outcome measures. Thirty-four participants completed the food diaries and body composition analysis (mean age 30.8 ± 11.2 y and mean BMI 30.7 ± 3.9 kg/m2). Significant differences were seen in water intake between Nutrition (791.2 ± 273.0 g) and Behaviour (1112.5 ± 197.6 g) (P = 0.03). Body composition and macronutrient intakes did not significantly differ among groups and/or over time. However, total intake of fruits and vegetables after the intervention was significantly different between Behaviour (5.85 ± 2.8 serving) and Nutrition (3.4 ± 1.4 serving) (P = 0.01). Meal-kit delivery with the added nutrition education and eating behaviours resulted in positive changes in food intake in adults living with an overweight condition and obesity. Future work should consider longer-term follow-up with larger sample sizes to confirm these findings. R. Howard Webster Foundation

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
