Macro partitioning
Combining GLP-1RA therapy with resistance exercise and high protein intake preserves fat-free mass better than GLP-1RA therapy alone in older adults with obesity.
To get the most benefit from GLP-1 medications without losing muscle, you must also do resistance exercise (like weights) at least twice a week and eat enough protein (1.0-1.2g per kg of body weight). This combination helps you lose fat while keeping your strength.
GoodSupportsHIGH confidence
A trial with randomization of patients to liraglutide, exercise, or exercise plus liraglutide showed that patients in the exercise plus liraglutide group lost more fat mass than the other two groups and maintained more fat-free mass than the liraglutide group.
Why this rating
Based on a specific RCT cited (ref 61), though the population may not be strictly sarcopenic obesity.

- Total daily protein intake of 1.6 g/kg/day is sufficient for maximizing resistance training-induced muscle gains, with an upper confidence interval of 2.2 g/kg/day.Strong
- Resistance exercise training combined with sufficient dietary protein intake acts synergistically to maximize skeletal muscle hypertrophy, with protein intake saturating around 1.6 g/kg/day for general populations and potentially requiring 2.0-2.2 g/kg/day for resistance-trained individuals.Strong
- Trans fats should be completely eliminated from the diet, as they increase LDL cholesterol, decrease HDL cholesterol, and are directly associated with increased coronary risk.Strong
