Can lifting weights and drinking protein shake help you keep muscle after weight-loss surgery?
Effectiveness of protein supplementation combined with resistance training to counteract disproportional fat-free mass loss following metabolic bariatric surgery: rationale and design of the ENRICHED randomised controlled trial

After weight-loss surgery, people often lose too much muscle. This study tests if doing strength exercises and drinking protein shakes helps them keep more muscle and feel stronger.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

After bariatric surgery, people who lose more than 30% of their total weight loss as fat-free mass (such as muscle) by three months are more likely to develop metabolic problems and have lower physical function.
For adults who have had metabolic bariatric surgery, combining structured resistance training with daily whey protein supplements may help preserve lean body mass during the first three months after surgery, compared to standard post-surgical care.
After metabolic bariatric surgery, adults who follow a structured protein supplement plan that starts at 20 grams per day and increases to 60 grams over 12 weeks, then transitions to dietary sources, consume more protein daily than those who follow standard dietary advice without supplementation.
For adults who have had metabolic bariatric surgery, a structured resistance training program using moderate weights, performed both in supervised sessions and at home 2–3 times per week, is likely to result in greater improvements in muscle strength and physical function than standard post-surgery care.
For adults who have had weight-loss surgery, adding strength training and extra protein to their routine may lead to better physical function and improved perception of their body image compared to standard post-surgery care.
