Energy balance

Metabolic and bariatric surgery (MBS) is the most effective treatment for obesity and type 2 diabetes, producing superior long-term weight loss and remission rates compared to lifestyle or pharmacologic interventions.

If you have severe obesity or type 2 diabetes, consider metabolic surgery. It is the most effective treatment for long-term weight loss and diabetes remission, far surpassing lifestyle changes or medications alone.

StrongSupportsVERY_HIGH confidence
Indeed, the most convincing evidence regarding the benefits of obesity management on morbidity and mortality comes from studies of surgical intervention... Long-term average weight loss in adults following the most common current metabolic/bariatric procedures ranges between 20% and 30%, exceeding long-term average weight loss achieved through lifestyle (~4%) and pharmacologic treatment (6%–15%).
