Snake-Derived pTOS Points to New Appetite-Control Path

Researchers found that after meals ball pythons exhibit a 1000-fold rise in pTOS, a gut-bacteria–derived metabolite. In mice, high doses of pTOS reduced appetite and caused weight loss without typical GLP-1 drug side effects, likely by activating neurons in the ventromedial hypothalamus. While promising, translating this to humans is still early, and the study in Nature Metabolism notes many more metabolites to explore.
