How Do Probiotics Affect Body Composition?


As a large portion of the gastrointestinal tract it is not a surprise that the organisms in your gut, its microbiome, affect how food is broken down and in turn affect your overall body composition. One of the mechanisms believed to facilitate this process is through the influence of your metabolism. Specifically, the gut’s bacteria help produce short chain fatty acids, process amino acids, and ferment indigestible carbohydrates all of which affect your energy stores.

Probiotics, as a part of your gut’s microbiome, can influence your metabolism as well. Over the past decade scientists have asked the question: knowing that the microbiome can affect the obesity pathway, can supplementation with probiotics affect body composition? The answer is yes. There have been numerous studies examining probiotics, primarily the Lactobacillus and Bifidobacterium species, influence on percent body fact and weight loss. A 2016 meta-analysis of randomized controlled trials found that supplementation with probiotics resulted in a significantly larger reduction in body weight and percent body fat than placebo.

Prebiotics, or the food for the probiotics, are equally important in this process. They too have been studied in weight loss and body composition and found to have beneficial effects. But it is the combination of a probiotic plus prebiotic, a synbiotic, that is believed to have the greatest effect. Synbiotics are believed to exert their beneficial effect on weight control via the gut-brain axis – activating host satiety pathways and affecting host control of appetite.

The formulation of Sound Body is backed by this research – utilizing the potent probiotic L. gasseri and two prebiotics inulin and oligofructose. Read more about our synbiotic – Sound Body and how it can help you achieve your goals.
