Habitual physical activity prevents the development of anabolic resistance mechanisms (such as reduced capillarity and inflammation) in older adults.
Regular exercise preserves the muscle's sensitivity to protein. This means you don't need to eat more protein than a young person; you just need to eat it effectively (distributed across meals).
ModerateSupportsMEDIUM confidence
The primary physiology changes considered to underpin the anabolic resistance of aging are precipitated or exacerbated by physical inactivity... Master athletes are generally considered successful models of aging... possessing similar body composition, muscle mass, and aerobic fitness as untrained adults more than half their age.
Why this rating
Based on indirect evidence from trained older adults and comparisons with young athletes.

- 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
