Physical activity interventions probably prevent frailty in adults aged 65 years and older, based on moderate certainty evidence from randomized controlled trials.
Engage in regular physical activity, including resistance, balance, and functional exercises, to help prevent frailty. While the specific dose varies, consistent movement is key for maintaining physiological reserves in older adults.
GoodSupportsMEDIUM confidence
Meta-analysis showed that physical activity probably prevents frailty (4 studies; frailty score pooled standardized mean difference, 0.24; 95% confidence interval, 0.04–0.43; P = .017, I2 = 57%, moderate certainty evidence).
Why this rating
Moderate certainty evidence from 4 RCTs with 1862 participants.

- 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
