Personalized behavioral weight loss (PBWL) involving a 4-week experimentation phase with continuous glucose monitoring (CGM) yields significantly greater 12-week weight loss than standard behavioral weight loss (BWL) with fixed prescriptions.

Instead of sticking to one diet, try a 4-week 'experiment' phase. Use a continuous glucose monitor (CGM) to test different macronutrient ratios (low-carb vs. low-fat) and meal frequencies (3 meals vs. snacks). Track how your blood sugar and hunger respond to each. After 4 weeks, pick the combination that gave you the best glucose control and felt most sustainable, then stick with it for the next 8 weeks. This personalized approach led to nearly double the weight loss of standard dieting in this study.

Mean 3-month weight loss (kg) was greater in PBWL (−7.08 (0.74)) than BWL (−3.79 (0.84), P = 0.03)... Experimentally‐derived personalized prescriptions supported greater 12‐week weight loss than standard recommendations.
