The statement "Body fat burns more calories than muscle" is actually false. Here's why:
1. **Metabolic Rate**: Muscle tissue is more metabolically active than fat tissue, meaning it burns more calories at rest. This is because muscle requires more energy to maintain itself compared to fat.
2. **Calories Burned During Exercise**: During physical activity, muscles play a significant role in calorie burning. Muscles are more efficient at burning calories during exercise compared to fat tissue.
3. **Weight Loss**: Increasing muscle mass can help increase overall calorie expenditure even when at rest, aiding in weight loss efforts.
Therefore, while it's true that fat does play a role in calorie burning, muscle is more metabolically active and burns more calories both at rest and during physical activity.
