Potential regulation of hunger perception and satiety. In dysbiosis SCFA production, specifically, acetate allows the activation of the parasympathetic nervous system, which increases ghrelin secretion and, therefore, hyperphagia. It also enables the secretion of insulin, favoring the development of obesity, hyperlipidemia, and insulin resistance. Abbreviations: SCFA: short-chain fatty acids; GLP1/2: glucagon-like peptide 1/2; PPY peptide tyrosine.
