Post-bariatric resistance training combined with whey protein supplementation significantly increases relative lower-limb muscle strength compared to usual care or protein supplementation alone.
If you've had Roux-en-Y gastric bypass, don't just rely on protein shakes to keep your strength. Start supervised resistance training about 6 weeks after surgery. Do 3 days a week, focusing on major muscle groups. Start with light weights (50% of what you can lift once) and gradually increase the weight as you get stronger. Also, make sure you're getting about 48 grams of whey protein daily in addition to your regular diet to support your muscles.
The increase in relative lower-limb muscle strength was higher in the PRO+EX group (+0.6 [0.3 to 0.8]) versus +0.1 (−0.1 to 0.4) and +0.2 (0.0 to 0.4) kg/kg body mass in CON and PRO groups, respectively (P = 0.021).
Why this rating
Randomized Controlled Trial with a reasonable sample size (n=76) and clear statistical significance, though limited to women undergoing a specific surgery.
