The Programs We’ve Identified Are Linked Below

Programs identified as having the most credible evidence of effectiveness, based on careful review in consultation with outside experts, are categorized as “Top Tier” or “Near Top Tier” (see sidebar for definitions). The other listed programs have been found promising but not yet Top Tier or Near Top Tier due to study limitations (such as only short-term follow-up) that underscore the need for additional testing prior to larger-scale implementation. As a nonprofit philanthropic foundation, we receive no financial benefit from any program, enabling us to serve as an impartial reviewer of the evidence.

Near Top Tier Healthy Living Partnerships to Prevent Diabetes (HELP PD) (A community-based lifestyle weight-loss program for overweight or obese adults with prediabetes): Randomized controlled trial shows effects on weight and other diabetes risk factors over two years.

Obesity Treatment Through Behavioral Training (Community-based program for obese adults, delivered through primary care practices): Randomized controlled trial shows meaningful weight loss sustained over a two-year period.
