Lifestyle interventions during OMM treatment should shift focus from caloric deficit for weight loss to optimizing health, specifically by mitigating lean mass loss through high protein intake and resistance training.
While taking OMMs, prioritize consuming 1.5g of protein per kg of fat-free mass (or 80-120g daily) and engage in resistance training 2-3 times per week. This helps preserve muscle mass and strength, which can be lost during rapid weight loss, and supports overall physical function.
During treatment, lifestyle approaches can mitigate medication-related effects and enhance health beyond weight loss, addressing concerns such as inadequate nutrition or muscle loss through protein intake and physical activity and reducing gastrointestinal side effects via dietary strategies.
Why this rating
Based on guidelines and expert consensus, though specific RCT data on optimal protocols is noted as lacking.

- Second-generation obesity management medications (semaglutide and tirzepatide) produce 15-20% body weight loss, significantly exceeding the 5-10% typically achieved by lifestyle interventions alone.Strong
- Discontinuation of second-generation OMMs leads to significant weight regain, highlighting the chronic nature of obesity and the need for long-term management or intensive lifestyle support upon discontinuation.Strong

- 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
