Clinical Trial Summary

Worldwide obesity is a public health concern that is defined by the World Health Organization as abnormal or excessive fat accumulation that may impair health. The main drivers of obesity pathogenesis seem to be a long-term of energy discrepancy between too many calories consumed and an increase of sedentary behavior. A growing body of evidence suggests that the set of microbes that live within the digestive tract, making up the gut microbiota (GM), play a metabolic role in energy regulation and substrate metabolism. Various factors can impact GM, one of these are dietary compounds that deeply affect the growth and metabolism of gut bacteria, since fermentation of nutrients is one core function of the intestinal microbes. Among fermentation products an array of small organic metabolites are short-chain fatty acids (SCFAs) acetate, propionate and butyrate. Among SCFAs, the C-4 fatty acid butyrate, the main fuel for the colonocytes, might have a potential in alleviating obesity and related metabolic complications. Butyrate could act as a regulator of body weight: a reasonable speculation is that butyrate acts on components of the energy balance, promoting energy expenditure and/or reducing energy intake. Preclinical studies have shown that butyrate supplementation prevent high-fat diet-induced obesity and it is able to treat obesity. With the sharp increase of obesity prevalence seen in the pediatric population, novel insights are necessary to counteract this epidemic disease, the outcome of the study is to see whether oral butyrate supplementation could exert similar effect in obese children.
