Interventions targeting the gut microbiota, specifically probiotics (Lactobacillus and Bifidobacterium strains), prebiotics, and short-chain fatty acids (SCFAs), can enhance muscle mass and physical performance in aging populations.
Focus on resistance training and protein intake as primary strategies for muscle health. While gut health is important, current evidence does not support specific probiotic or prebiotic supplements as a reliable standalone treatment for sarcopenia in humans. More research is needed before these can be recommended as standard therapy.
Probiotics, prebiotics, SCFAs, and bacterial products are potential novel therapies to enhance muscle mass and physical performance. Lactobacillus and Bifidobacterium strains restored age-related muscle loss.
Why this rating
Based on a systematic review of 26 pre-clinical and 10 clinical studies, but with noted heterogeneity and inconsistent clinical outcomes.

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
