Hormonal

GLP-1 and GIP receptor agonists (semaglutides and tirzepatides) effectively reverse overweight, obesity, and type 2 diabetes by targeting neuro-hormonal pathways, achieving mean weight reductions of 10.2% and 15.0% respectively, whereas lifestyle interventions fail to produce permanent weight loss due to compensatory biological mechanisms.

If you have struggled to maintain weight loss through diet and exercise alone, recognize that this is likely due to biological resistance (hormonal signals), not a lack of willpower. Consult a healthcare provider about GLP-1/GIP agonists (like semaglutide or tirzepatide), which target these specific pathways. While currently expensive, these treatments offer a clinically proven path to significant weight loss and diabetes management that lifestyle changes alone have failed to provide for most people.

GoodSupportsHIGH confidence
The evidence that these medicines are effective in helping people lose weight and manage their metabolisms is robust. Trial data suggest semaglutide to be associated with a mean 10.2% weight reduction and tirzepatides with a mean 15.0% weight reduction in patients without diabetes after one year... nearly all [who intentionally lose weight] will return to at least their baseline weight within five years... compensatory responses to dieting and weight loss favor weight regain, by both increasing hunger and appetite and promoting energy storage.

Why this rating

The paper cites robust trial data and established safety records for diabetic use, though it notes long-term data for non-diabetic weight loss is still in its 'infancy'.
