What percentage of the body's weight is accounted for by muscles?

1. 30%

2. 40%

3. 50%

4. 60%

The correct answer is: 40%

Muscles are a significant component of body composition and typically account for around 40% of an individual's total body weight, depending on factors such as age, gender, and fitness level. This percentage reflects the mass of muscle tissue relative to other body tissues, including fat, bones, organs, and fluids. In men, muscle mass can be higher, potentially approaching or exceeding this percentage, while in women, it may be slightly lower. Understanding the distribution of muscle mass is important in fields such as nutrition, fitness, and overall health assessment. Hence, the figure of approximately 40% is widely accepted in exercise science and health studies as a general guideline for muscle percentage in the body.
