Do gut probiotics play a role in weight loss?
Yes, they do.
Trillions of microorganisms inhabit the human gut, forming the gut microbiota. Among them, probiotics like Lactobacillus and Bifidobacterium can aid in digesting hard-to-digest foods, participate in the metabolism of sugars and proteins, promote the absorption of minerals like iron, magnesium, and zinc, regulate hunger signals, and influence appetite and satiety.
Research indicates that intestinal epithelial cells produce a fasting-induced adipocyte factor (Faif), an inhibitor of lipoprotein lipase. In individuals with normal weight, Faif in adipocytes is inactive when not fasting but becomes active in times of hunger, utilizing stored fat for energy. In obese individuals, Faif remains inactive for extended periods, leading to inefficient fat consumption and promoting fat synthesis. Gut microbiota can regulate the expression of Faif.
If there’s an imbalance in gut microbiota, it can be regulated by incorporating probiotic powder or consuming probiotic drinks. Aiding in maintaining a healthy gut microbiota balance and supporting weight loss efforts. Therefore, achieving weight loss requires not only a balanced diet and exercise but also ensuring gut microbiota balance.

Chan, from Harvard-affiliated Massachusetts General Hospital (MGH), found that a diet rich in healthy and plant-based foods is linked with the presence and abundance of certain gut microbes that are also associated with a lower risk of developing conditions such as obesity, Type 2 diabetes, and cardiovascular disease1.
- The same study also found robust microbiome-based biomarkers of obesity as well as markers for cardiovascular disease and impaired glucose tolerance1.
- According to Harvard Medical School, the latest research shows that probiotics may offer benefits against a range of health conditions, including allergies, arthritis, asthma, cancer, depression, heart disease, and gastrointestinal (GI) problems. Probiotics may even help with weight loss2.
- A study from the National Institutes of Health (NIH) found that mice fed a high-sugar diet lost immune cells in their guts that normally help regulate the absorption of dietary fat. This loss, which led to weight gain and early signs of diabetes, was driven by changes in gut microbes caused by high sugar intake3.
