Study of the intestinal microbiota during a dietary intervention in real life of overweight subjects (obese or overweight)
Dietary modulations and impact on the microbiota
Several studies have shown that constituents of the diet can be used to significantly modify the quality of the gut microbiota by targeting certain species of bacteria..
Specific bacterial groups
Some studies suggest that modifications, more specific than those obtained at the level of the phylum, would be involved in the development of obesity; these would be changes at the level of specific species. For example, the abundance of bacterial populations of the Bifidobacterium group in the first year of life is greater in children who maintained normal weight than in overweight children at age 7 . Another recent study also shows that the number of bacteria in the Bifidobacterium group is significantly higher in healthy subjects than in overweight and obese subjects
