The role of short-chain fatty acids in driving obesity: Should we blame acetate?5 Aug 2016
by Patrice D. Cani
In a recent paper by Perry et al., researchers describe an investigation into the putative mechanisms by which gut microbiota alterations may lead to obesity, insulin resistance, and metabolic syndrome. Authors describe increased production of acetate by altered gut microbiota in rats. They link this to activation of the parasympathetic nervous system, increased glucose-stimulated insulin secretion, higher ghrelin secretion, hyperphagia, and obesity. Thus, they point to increased acetate production as a driver of metabolic syndrome.
