Probiotics may reduce the number of calories you absorb from food. They also affect levels of hormones and proteins related to appetite and fat storage, as well as potentially reduce inflammation, which can drive obesity.

Boosting the good bacteria in your digestive tract, called the gut microbiome, can help you improve your body composition. Probiotics are living microorganisms, similar to the body-friendly bacteria in your gut, which can be included in your diet to derive health benefits like reduced risk of gastrointestinal disorders, better immune function, improved cardiovascular health, and weight loss.

The bacteria in your digestive tract can influence the way your body absorbs nutrients from food and uses them for energy. Probiotics help lower the number of calories (dietary fats) you absorb; thereby increasing the excretion of bile from the body, which in turn promotes the loss of belly fat.

Consumption of probiotics leads to the release of the satiety hormone GLP-1 in the body, which will reduce your appetite and increase the resting energy expenditure, allowing you to burn fat and lose more weight. Even obese people can experience rapid weight loss with probiotic supplements.
