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.

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.

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.

Taking extra protein shakes after losing weight doesn’t help you keep the weight off any better than eating the normal amount of protein in your daily diet.

For middle-aged men doing strength training, whey protein and this collagen supplement have similar effects on muscle gain and fat loss.
