Energy balance
Intentional weight loss through lifestyle modifications or pharmacotherapy provides consistent cardiovascular protective effects by improving metabolic profiles and cardiac structure.
If you are obese, losing weight intentionally through diet and exercise is one of the best things you can do for your heart. It improves your metabolism and heart function. Focus on sustainable changes rather than quick fixes.
GoodSupportsHIGH confidence
Intentional weight loss has a consistent cardiovascular protective effect, but unintentional weight loss due to progressive catabolism and loss of muscle mass could be associated with poor cardiovascular outcomes.
Why this rating
Supported by multiple meta-analyses and large cohort studies (e.g., Look AHEAD, Da Qing).
