Intensive lifestyle intervention (ILI) does not significantly reduce the risk of major cardiovascular events (mortality, myocardial infarction, stroke) in adults with overweight/obesity and type 2 diabetes compared to standard diabetes support and education.
Even if lifestyle changes do not significantly lower your risk of heart attacks or death from cardiovascular causes, they still provide major benefits for your diabetes control, kidney health, and daily quality of life. The effort is still worthwhile for these other critical health improvements.

The study was stopped for futility after a median of almost 10 years of intervention, as it was apparent that assignment to ILI was associated with a nonsignificant hazard ratio (HR) = 0.95 (95% CI: 0.83- 1.09) relative to DSE
Why this rating
Large, long-term RCT with clear primary endpoint analysis.

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
