Combining resistance training with progressive whey protein supplementation (up to 60g/day) initiated 3 weeks post-surgery counteracts disproportional fat-free mass loss in patients undergoing metabolic bariatric surgery.
If you have had bariatric surgery, standard care may not be enough to protect your muscle. This protocol suggests starting resistance training (both home and supervised) and gradually increasing whey protein intake to 60g per day, starting 3 weeks after surgery. This combination aims to preserve muscle mass, which is crucial for long-term health and metabolic function.
Resistance training (RT) complemented with protein supplementation has been shown to be effective for maintaining and improving FFM in healthy and clinical populations... The ENRICHED intervention consists of two consecutive phases, starting 3 weeks after surgery... Phase 1 (3–14 weeks post- MBS) focuses on home- based and supervised RT and gradually increasing protein supplementation.
Why this rating
This is a study protocol/rationale; no results are reported yet. It describes a large-scale RCT design (n=400) but lacks outcome data.

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
