Are Probiotics Effective for Weight Loss?
Probiotics are supplements that contain live microorganisms intended to maintain or improve the "good" bacteria in the body. While they can influence gut microbiota, which plays a role in metabolism and fat digestion, their effect on weight loss has not been clearly proven.
Gut Microbiota and Weight Loss
Consultant gastroenterologist and hepatologist Dr. Deborah Chew Chia Hsin explained that individuals with excess weight, obesity, and diabetes often experience gut dysbiosis, where there is a lack of healthy gut microbiota. This imbalance can lead to a higher percentage of harmful bacteria versus beneficial bacteria.
Mixed Results in Studies
Studies have explored the role of probiotics in managing obesity and weight loss, but the results have been mixed. Some findings found no significant benefits from probiotic supplements, while others reported slight to moderate benefits in helping with weight loss.
Proper Storage and Dosage
Dr. Chew emphasized that probiotics are only effective if they contain the right bacterial strains, such as Lactobacillus and Bifidobacterium, and are stored properly. She warned that live bacteria may not survive if stored at above 25°C, and that consuming the recommended dosage is crucial to avoid side effects like bloating.
Dietitian’s Perspective
Dietitian Jazlina Syahrul agrees that probiotics have the potential to support metabolism and gut microbiota balance, but they are not a primary solution or shortcut for weight loss. She suggests that maintaining a balance of good bacteria in the gut may support weight loss, but more extensive research is needed to confirm the effectiveness of probiotics in this area.
Conclusion
Probiotics may contribute to weight loss, but their effect is minimal and slower compared to lifestyle interventions like diet and exercise. While there is some early evidence, probiotics are not a "magic pill" for weight loss. They serve as additional support, rather than a substitute for a balanced diet and consistent exercise.
