On 21 May 2026, Lilly announced positive topline results from TRIUMPH-1 (not yet peer-reviewed), the pivotal Phase 3 obesity trial
The overall physiological effects include promoting insulin secretion, inhibiting glucagon release, delaying gastric emptying, and influencing appetite
On Tuesday morning, Eli Lilly reported that orforglipron met the benchmarks of the companys Phase III ATTAIN-2 study
Short-chain fatty acids (SCFAs) such as butyrate, a bacterial metabolite produced from dietary fibre, can directly trigger GLP-1 release by binding to the membrane receptor GPR43 ( Both preclinical and clinical studies have demonstrated that GLP-1s modulate the gut microbiota composition by delaying gastric emptying and altering luminal glucose ( Firmicutes Lachnospiraceae and Clostridiales ), alongside an increase in Proteobacteria (e.g., Burkholderiales bacterium YL45 ) and Akkermansia muciniphila a species largely associated with high-fibre diets and mucosal barrier health ( Firmicutes/Bacteroidetes ratio and an increase in Prevotella , species that have been linked to lower inflammation ( Firmicutes/Bacteroidetes ratio was observed ( The findings concerning human gut microbiota remain controversial

The consequences range from subtle, such as gradual peptide degradation that skews dose-response curves, to overt, such as visible contamination that invalidates an entire experimental series
