Exercise Physiology

How physical activity affects body weight, metabolism, and health.

Plain English

Patient-Friendly Explanation

Exercise does more than burn calories — it builds muscle (which burns more calories at rest), improves mood, and helps maintain weight loss. Even 30 minutes of walking daily makes a difference.

Medical

Clinical Definition

Physical activity increases total energy expenditure through exercise activity thermogenesis (EAT) and can elevate resting metabolic rate via increased lean body mass. Guidelines recommend 150-300 min/week moderate activity for weight maintenance.

Key Insight

Why It Matters

Exercise is most effective for weight loss maintenance, not initial weight loss. Combining exercise with medical treatment produces the best long-term outcomes.
