For quick launch: February 25, 2026

Boston, MA—Individuals residing with kind 2 diabetes (T2D) had a considerably decrease threat of poor cardiovascular well being after they used a GLP-1 receptor agonist (GLP-1 RA) together with adhering to wholesome life-style habits, in accordance with a brand new examine led by researchers at Harvard T.H. Chan School of Public Health and the Department of Veterans Affairs Boston Healthcare System. The examine is the primary giant cohort investigation to look at the mixed results of wholesome habits and GLP-1 RAs on coronary heart well being, exhibiting that the 2 methods are complementary, fairly than substitutes, in enhancing cardiovascular outcomes amongst sufferers with diabetes.

“Our findings underscore that, even in the era of highly effective GLP-1 pharmacotherapy, lifestyle habits remain central to diabetes management and cardiovascular risk reduction and can substantially amplify the benefits of modern medications,” stated corresponding writer Frank Hu, Fredrick J. Stare Professor of Nutrition and Epidemiology and chair of the Department of Nutrition.

The study was printed February 25, 2026, in The Lancet Diabetes & Endocrinology.

The researchers examined the approach to life habits, GLP-1 RA utilization, and cardiovascular well being outcomes of greater than 98,000 adults residing with T2D and with none prior heart problems, utilizing information from the Veterans Affairs’ Million Veteran Program from 2011 to 2023. The wholesome life-style habits the researchers thought of have been nutritious diet, common train, not smoking, restful sleep, minimal alcohol consumption, good stress administration, social connection and help, and no opioid use dysfunction. The main hostile cardiovascular occasions (MACEs) they thought of have been non-fatal stroke, myocardial infarction, or cardiovascular dying. More than 13,000 of the examine contributors used a GLP-1 RA. When analyzing the connection between life-style, GLP-1 RAs, and coronary heart well being, the researchers managed for potential demographic and health-related confounders.

The examine discovered that sustaining a wholesome life-style and utilizing a GLP-1 RA led to considerably lowered MACE threat. Those who used a GLP-1 RA and adhered to 6 to eight wholesome habits had a 43% decrease threat in comparison with those that didn’t use a GLP-1 RA and adhered to a few or fewer such habits. The examine additionally discovered that wholesome habits and GLP-1 RA utilization independently benefited coronary heart well being. Those who adhered to all eight wholesome habits had a 60% decrease threat in comparison with those that adhered to 1 or fewer, and people who used a GLP-1 RA had a 16% decrease MACE threat in comparison with those that didn’t. 

“From a public health perspective, the results underscore the continued importance of population-level investments and policy in promoting healthy diet, physical activity, sleep, stress management, and social connection, even in a modern drug era,” Hu stated. “As novel therapies expand, scalable lifestyle interventions remain essential for reducing the overall burden of cardiovascular disease and other chronic diseases.”

The researchers famous that the examine had some limitations. The outcomes have been primarily based on observational information, which means residual confounding by socioeconomic standing and different elements was attainable, although these variables have been accounted for within the evaluation. Additionally, the examine inhabitants primarily consisted of white male veterans, which can restrict the generalizability of the outcomes, although the general findings have been constant throughout totally different racial and ethnic teams and between women and men.
