Gastric bypass actually sheds more weight than sleeve gastrectomy (22% vs 17%). And for blood sugar, GLP-1 drugs tie with surgery—no clear winner. The Lancet study might oversell these comparisons. https://s.fitbodyscience.com/Q8Gz37

The breakdown

A social media post claimed sleeve gastrectomy is best for weight loss and GLP-1 drugs best for blood sugar, but research tells a different story.

Other research on weight loss found that people who had gastric bypass surgery lost more weight than those who had sleeve gastrectomy, so sleeve isn't the top option. For blood sugar control, studies show that GLP-1 drugs and bariatric surgery lower blood sugar about equally, meaning GLP-1 therapy isn't superior as claimed. The post linked to a study, but the evidence here comes from separate research that contradicts both claims.

Bottom line

If you're considering options for weight loss or blood sugar control, the research suggests bariatric surgery, especially gastric bypass, may be more effective overall, and GLP-1 drugs are not clearly superior for blood sugar alone.
