Some studies suggest a link between probiotic consumption and weight loss when part of a balanced diet. However, further clinical trials will help determine how doctors can utilize this for patient treatment.

Typically, they come in yogurt form or specifically formulated drinks and supplements. They are also available in fermented foods such as kefir, tempeh, kombucha, miso, kimchi, and sauerkraut. Learn more about probiotic foods here. Probiotics can manipulate the gut microbiome. The gut microbiome refers to the collection and activity of microorganisms, including bacteria, that reside in the gastrointestinal (GI) tract. Dietary choices can influence the gut microbiome in helpful or harmful ways to overall health. People can add beneficial bacteria, such as lactobacilli or bifidobacterium, to their gut microbiome by using probiotic supplements or formulated foods. Learn more about the microbiome and its role in health via MNT’s dedicated hub. The Food and Beverage Administration (FDA) does not regulate probiotics and treats them like other health supplements. However, it does generally consider them safe. Additionally, the FDA includes many microorganisms in the Generally Recognised As Safe (GRAS) list, such as the lactic acid producing strains of probiotics commonly used in yogurt, Lactobacillus bulgaricus and Streptococcus thermophilus. Probiotics and weight loss The relationship between probiotics and weight loss is complex and the subject of ongoing research. A 2021 scientific review of data suggests that the intake of probiotics could lead to weight loss over 12 weeks in combination with other healthy lifestyle habits, such as regular physical activity. Another review looked at the relationship between obesity and the gut microbiome. Those with a higher body mass index (BMI) may have reduced diversity in their gut microbiome. The review suggests the consumption of probiotics may alter the gut microbiome in ways that promote weight loss in people with high BMI by regulating appetite, metabolism, and energy expenditure. Learn more about the potential benefits of probiotics here. Probiotic risks and safety Similar to other supplements, probiotics are not subject to the same regulations as medications or food. This lack of regulation applies to supplements. Therefore, it is not always possible to ensure that the probiotic contains the bacteria strains and quantities a product may claim. Additionally, many bacteria populations in a probiotic supplement may change over time due to storage conditions or temperature fluctuations. A 2015 study reports very rare cases of unwanted bacteria-host interactions or other side effects of probiotics, usually in immunosuppressed people or those otherwise severely ill. The researchers note that taking supplements always poses some risk and that the safety of probiotics requires further study. Foods that contain probiotics, such as yogurts, are regulated by the FDA. They may not contain probiotics in as high quantities as supplements but may generally be a safer option for people concerned about risks. Probiotics are not a replacement for conventional medicine. Probiotics should not be taken by people who are immunocompromised or otherwise severely ill. If pregnant or nursing, seek medical advice prior to use. Probiotics cannot treat or cure any disease or condition.

Labeling Probiotic measurements are Colony Forming Units (CFUs) which estimate the number of viable cells in a given sample under controlled conditions. Current regulation only requires a manufacturer to declare the total weight of the microbes, alive or dead, which does not correlate to the actual dose a person may consume. When choosing a supplement, the Office of Dietary Supplements (ODS) recommends looking for a supplement declaring total CFUs at the end of the product’s shelf life. Dosage Many probiotic supplements have 1–10 billion CFUs, and some have over 50 billion. There is no defined upper consumption limit, but there is currently also no evidence to suggest that higher CFU counts have better health effects. People should also consider the types and amounts of different strains. These do not necessarily indicate safer or higher quality products, however. Alternatives to supplements While capsules and powders are the most common probiotic supplements, probiotics are also available in yogurts, fermented milk drinks, and even infused into flavored drinks. An individual’s gut microbiome will also adapt gradually to diet changes, with different diets rendering different changes. Probiotics alone will not likely support weight loss and should be taken in combination with proven weight loss methods, such as reducing energy intake and increasing physical activity. Frequently asked questions Below, we look at some common questions about probiotics for weight loss. Can probiotics help with weight loss The evidence shows a link between probiotics and weight loss when a person uses them alongside a balanced diet and exercise regimen. A person may need to try different products to find a probiotic supplement that suits their needs. Is there a recommended probiotic dosage or intake suggestion No. There is currently no research to suggest an ideal number of CFUs or preferred methods of consuming probiotics. Summary Probiotics for weight loss are generally safe and can complement a person’s diet and exercise regimen. Individuals should try different options to find what works best for them. Anyone with concerns about the safety of taking probiotics should speak to a doctor for guidance. Experts are continually studying probiotics to find the most effective bacteria strains and the optimal CFU dosage. They may then be able to confirm the link between the gut microbiome and weight loss.
