What are the effects on the gut microbiota?
Obesity is associated with qualitative changes in the gut microbiota. The microbiota in obese people has been shown to have a higher Firmicutes/Bacteroidetes ratio than that of healthy people. This qualitative difference has also been revealed in children having maintained a healthy weight throughout childhood, who have more Bifidobacteria than children who are overweight. This suggests that qualitative changes in the gut microbiota, which more specifically target certain genera or strains of bacteria, may be related to obesity and that not all bacteria play exactly the same role in the metabolic dialogue with their host.
It has been established that obesity is linked to chronic systemic inflammation, known as “low-grade inflammation”, evolving discreetly in the background without there being any obvious site of inflammation. This condition may be correlated with Lipopolysaccharides (LPS), found in low concentrations in healthy subjects but in high quantities in people who are overweight and present dysbiosis.

How can weight gain be controlled using probiotics?
It has been shown that certain probiotic bacteria contribute to weight loss, a reduction in abdominal fat and also a decrease in waist and hip measurements.
Probiotics seem to regulate the production of bad bacteria, thereby reducing calorie absorption. Their bacteria may also promote the release of the satiety hormone in the gut and inhibit the absorption of fats, promoting weight loss.
