Caloric restriction alone in older adults with sarcopenic obesity leads to significant loss of lean muscle mass and grip strength, worsening sarcopenia.
If you are an older adult with obesity, simply eating less (caloric restriction) without exercise can cause you to lose muscle, not just fat. This makes you weaker and more frail. To avoid this, you must combine dietary changes with resistance exercise and ensure you are eating enough protein.
GoodRefutesHIGH confidence
Meta-analysis [21] of 33 intervention studies lasting 8–24 weeks reported that calorie restriction alone without resistance training leads to the loss of muscle mass and loss of handgrip strength
Why this rating
Based on a meta-analysis of 33 studies and a specific RCT cited.

- Total daily protein intake of 1.6 g/kg/day is sufficient for maximizing resistance training-induced muscle gains, with an upper confidence interval of 2.2 g/kg/day.Strong
- Resistance exercise training combined with sufficient dietary protein intake acts synergistically to maximize skeletal muscle hypertrophy, with protein intake saturating around 1.6 g/kg/day for general populations and potentially requiring 2.0-2.2 g/kg/day for resistance-trained individuals.Strong
- Trans fats should be completely eliminated from the diet, as they increase LDL cholesterol, decrease HDL cholesterol, and are directly associated with increased coronary risk.Strong
