An observational study published in the journal Health Psychology tracked 112 adults with overweight or obesity enrolled in a structured 12-week behavioral weight loss program. Using self-reported mobile app food logs and daily wireless scale weigh-ins, researchers measured dietary repetition and caloric stability. Participants with higher meal repetition lost an average of 5.9% of their body weight, compared with 4.3% for those eating a wider variety of foods; for every 100-calorie increase in daily fluctuation, weight loss dropped by about 0.6%. No cause-and-effect relationship was established, the study relied on self-reported data, and no conflicts of interest were reported. Registered dietitians not involved in the research noted that while consistency may help, the meals need to be nutrient-dense and real-world schedules can make strict repetition challenging.
