Effect of weight loss program using prebiotics and probiotics on body composition, physique, and metabolic products: longitudinal intervention study.

The relationship between gut microbiota and obesity has recently been an important subject for research as the gut microbiota is thought to affect body homeostasis including body weight and composition, intervening with pro and prebiotics is an intelligent possible way for obesity management. To evaluate the effect of hypo caloric adequate fiber regimen with probiotic supplementation and physical exercise, whether it will have a good impact on health, body composition, and physique among obese Egyptian women or has no significant effect. The enrolled 58 women, in this longitudinal follow-up intervention study; followed a weight loss eating regimen (prebiotic), including a low-carbohydrate adequate-fiber adequate-protein dietary pattern with decreased energy intake. They additionally received daily probiotic supplements in the form of yogurt and were instructed to exercise regularly for 3 months. Anthropometric measurements, body composition, laboratory investigations, and microbiota analysis were obtained before and after the 3 months weight loss program. Statistically highly significant differences in the anthropometry, body composition parameters: and obesity-related biomarkers (Leptin, ALT, and AST) between the pre and post-follow-up measurements at the end of the study as they were all decreased. The prebiotic and probiotic supplementation induced statistically highly significant alterations in the composition of the gut microbiota with increased relative abundance of Lactobacillus, Bifidobacteria, and Bacteroidetes and decreased relative abundance of Firmicutes and Firmicutes/Bacteroidetes Ratio. Hypo caloric adequate fiber regimen diet with probiotics positively impacts body composition and is effective for weight loss normalizing serum Leptin and AST.

Activity of probiotics from food origin for oxalate degradation.

Kidney stones composed of oxalate are a significant health problem. It has been suggested that modification of the intestinal microbiota to reduce the amount of oxalate in the digestive system could be an effective treatment. There have been several studies into the use of lactic acid bacteria for the degradation of intestinal oxalates. We isolated 88 lactic acid bacteria strains from a range of dairy products, and screened for their ability to degrade oxalate. Using the oxalate-degrading Enzymatic Activity Index and the viable cell counts, five strains of Lactobacillus fermentum and two strains of Lactobacillus gastricus were identified as having strong oxalate degradation abilities, and were further investigated. All seven strains were able to tolerate acid (pH 4 and 3), bile salts (0.3%), phenol (0.3%), and to produce exopolysaccharides. They were resistant to a wide range of antibiotics. Among these strains, Lactobacillus fermentum NRAMJ5 and Lactobacillus gastricus NRAMJ2 were, therefore, good candidates as probiotics for managing hyperoxaluria.
