Brief Summary
Calorie restriction (CR), which has the potential effect on weight loss and blood amino acids, has been demonstrated to associate with gut microbiota in humans, especially in obese individuals. However, studies for simultaneously evaluating enterotype-dependent impacts of CR on the gut microbiota and blood amino acids in nonobese individuals are still limited. Here, 41 nonobese individuals received a 3-week CR diet with approximately 50% fewer calories than a normal diet. The investigators measured individuals' BMI and blood amino acid concentration, along with the gut microbiota before and after the intervention. In this trial, 28 Enterotype Bacteroides (ETB) subjects and 13 Enterotype Prevotella (ETP) subjects were identified before the intervention. The purpose of this intervention study is to evaluate the effect of calorie restriction on BMI loss, amino acid, and gut microbiota in healthy volunteers of two different enterotypes and provide useful insights for potential application of gut microbiome stratification in personalized nutrition intervention.
