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.
