People using high-protein meal replacements during weight loss report less overeating and fewer impulsive food cravings than those on a standard low-calorie diet, indicating better control over eating habits.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Whether protein-supplemented meal replacements consistently improve self-reported eating behaviors (e.g., overeating, impulsivity) compared to standard diets in obese populations.
A systematic review and meta-analysis of at least 15 RCTs (n > 1,200 total participants) comparing protein-supplemented meal replacements with standard diets, using validated tools like the Three-Factor Eating Questionnaire or Binge Eating Scale, measuring changes in overeating and impulsivity at 6 and 12 months.
Whether adding 20g/day of soy protein to a VLCD reduces overeating behavior more than an isocaloric placebo, independent of behavioral coaching.
A double-blind RCT of 180 obese adults (BMI 25–39.9 kg/m²) randomized to identical 800 kcal/day VLCDs with either 20g/day soy protein isolate or maltodextrin placebo, with identical behavioral coaching, measuring overeating behavior via the Three-Factor Eating Questionnaire at baseline, 4, and 12 months.
Whether individuals who consume higher protein during weight loss maintain improved eating behaviors over 3 years compared to those with lower intake.
A prospective cohort of 900 adults undergoing weight loss, tracking daily protein intake and measuring eating behavior via validated questionnaires at baseline, 6, 12, and 36 months, adjusting for weight loss, coaching intensity, and baseline impulsivity.
Whether individuals who successfully maintain weight loss for 2 years report higher protein intake and lower overeating scores during their initial diet phase compared to those who regain weight.
A case-control study comparing 200 adults who maintained >5% weight loss for 2 years with 400 who regained >3 kg, retrospectively analyzing their protein intake and overeating scores during the first 12 months of dieting.
Whether higher protein intake during weight loss is correlated with lower overeating scores at a single time point.
A cross-sectional analysis of 4,000 adults who recently completed a weight loss program, comparing overeating scores (via TFEQ) with self-reported average daily protein intake during the diet phase, adjusting for BMI and weight loss percentage.
