Adherence
Resistance training is the most effective form of exercise for improving protein synthesis rates and reversing muscle loss, superior to aerobic exercise alone.
Do resistance training (lifting weights or using resistance bands) at least twice a week. This is more important for building muscle than just walking or cycling. Work with a physical therapist to adapt the exercises to your strength level.
GoodSupportsHIGH confidence
Aerobic exercise is encouraged, but it is resistance training that has been shown repeatedly to improve rates of protein synthesis and reverse muscle loss.
Why this rating
Supported by cited guidelines (ESPEN, ACSM) and systematic reviews.

More from this paper
- Malnutrition management must prioritize the maintenance and restoration of muscle mass rather than generalized weight gain, as low muscle mass is a critical determinant of adverse health outcomes including mortality, readmission, and functional decline.Good
- HMB (beta-hydroxy-beta-methylbutyrate) supplementation acts as a potent stimulator of protein synthesis and inhibitor of protein breakdown, helping to slow or reverse muscle loss in aging, illness, or starvation.Good
