GLP-1 and Muscle Preservation: How to Keep Strength While Losing Weight
By The RevitalizeMe Clinical Team
Why Muscle Matters During Weight Loss
When you lose weight quickly, a portion often comes from lean body mass — including muscle. Preserving muscle supports metabolic rate, physical function, and long-term weight maintenance.
Evidence-Based Strategies
1. Prioritize Protein
Aim for adequate protein intake (typically 1.2–1.6 g per kg of body weight, or higher for older adults) to support muscle protein synthesis even in a calorie deficit.
2. Resistance Training
Two to three strength-training sessions per week help signal your body to retain muscle. Focus on compound movements and progressive overload.
3. Gradual Weight Loss
Moderate calorie deficits and steady weight loss (about 0.5–1% of body weight per week) are associated with better preservation of lean mass than aggressive restriction.
4. What the Pipeline Holds
Next-generation combinations like CagriSema (semaglutide plus the amylin analog cagrilintide) are being studied for their potential to better preserve bone and lean mass during weight loss. Stay informed as new options become available. Talk to your provider about combining GLP-1 therapy with a nutrition and exercise plan tailored to preserving muscle and strength.
