In patients with type 2 diabetes, achieving >=10% weight loss in the first year of lifestyle intervention is associated with a significantly reduced risk of the primary composite cardiovascular outcome and cardiovascular death/MI/stroke.
If you are doing lifestyle changes for diabetes, aiming for a 10% weight loss in the first year is a strong predictor of better heart health outcomes, including reduced risk of heart attack and stroke. This benefit exists even if the overall trial didn't show a statistically significant difference for everyone.
ModerateSupportsMEDIUM confidence
Individuals who lost at least 10% of body weight in the first year had a 21% lower risk for the primary outcome (adjusted HR, 0.79; 95% CI, 0.64–0.98; P=0.03) and a 31% reduction for a secondary outcome of cardiovascular death, MI, and stroke (adjusted HR, 0.69; 95% CI, 0.53–0.91; P<0.05).
Why this rating
Post-hoc analysis of a stopped trial; statistically significant but exploratory.

- Intensive lifestyle intervention for weight loss in type 2 diabetes does not significantly reduce the primary composite cardiovascular endpoint (death from CV causes, nonfatal MI, nonfatal stroke, or hospitalization for angina) compared to diabetes support and education.Good
- Intensive lifestyle intervention reduces total mortality and cardiovascular mortality in type 2 diabetes patients, with hazard ratios similar to those seen with SGLT2 inhibitors and GLP-1 agonists, although these reductions did not reach statistical significance in the Look AHEAD trial.Moderate
