Yes, modestly. Muscle burns more calories at rest than fat, and building and keeping it raises your resting metabolic rate and protects it during weight loss. That's why strength training matters for weight management, not just looks.
- Muscle burns more at rest than fat.
- Strength training builds and preserves it.
- Keeping muscle protects your metabolic rate.
- It also improves strength, health and shape.
Why muscle matters
Muscle is active tissue that uses energy around the clock, so more of it nudges your resting burn up. Over a day the effect is modest but real, and it compounds with the other benefits of strength training.
Protecting muscle in a deficit
When you lose weight, some loss can come from muscle — which lowers your rate. Enough protein plus resistance training signals your body to keep muscle and lose more fat instead.
The bigger picture
Beyond metabolism, muscle improves strength, posture, bone health and how your body looks at a given weight. It's one of the best long-term investments for weight management.
