Macro partitioning
Post-bariatric patients should target a minimal protein intake of 60 g/day up to 1.5 g/kg ideal body weight per day, utilizing liquid protein supplements (30 g/day) in the early post-operative period to prevent lean body mass loss and protein malnutrition.
After bariatric surgery, your body needs more protein to keep your muscle while you lose fat. Because solid protein foods might upset your stomach early on, use liquid protein supplements (about 30g daily) to help you hit your target of 60g to 1.5g per kg of your ideal body weight each day. This protects your muscle mass during rapid weight loss.
Current guidelines suggest a minimal protein intake of 60 g/day and up to 1.5 g/kg ideal body weight per day... The use of liquid protein supplements (30 g/day) can facilitate adequate protein intake in the first period after surgery.
