Hormonal

Oxyntomodulin (OXM) induces superior body weight loss compared to selective GLP-1 receptor agonists by simultaneously activating both GLP-1 and glucagon receptors, thereby suppressing food intake and increasing energy expenditure.

Oxyntomodulin (OXM) is a gut-derived hormone that activates both GLP-1 and glucagon receptors. Clinical studies show that administering OXM subcutaneously three times daily before meals leads to modest but significant weight loss (approx. 2.3 kg over 4 weeks) in overweight individuals. It also improves glucose tolerance in Type 2 Diabetes patients. The dual receptor activation is key: GLP-1 reduces appetite and slows gastric emptying, while glucagon receptor activation may increase energy expenditure. However, the short half-life requires frequent dosing, and potential side effects like nausea must be managed.

GoodSupportsHIGH confidence
Oxyntomodulin (OXM) is a peptide hormone released from the gut in post-prandial state that activates both the glucagon-like peptide-1 receptor (GLP1R) and the glucagon receptor (GCGR) resulting in superior body weight lowering to selective GLP1R agonists. OXM reduces food intake and increases energy expenditure in humans.

Why this rating

Based on human clinical trials (acute and chronic) and robust preclinical data, though long-term safety and optimal dosing ratios are still being defined.
