Metabolism and Muscle: Your Body's Metabolic Engine
Metabolism isn't just about fat; it largely depends on your muscle. Muscle is the body's metabolic engine.
Why is muscle so important?
1. **Muscle = Primary glucose-consuming tissue** When we eat, a large portion of glucose is used by muscles. If you have less muscle, sugar stays in the blood for longer.
2. **Insulin sensitivity depends on muscle** Healthy muscle responds well to insulin. Less muscle means a higher chance of increased insulin resistance. This is very important in early prediabetes.
3. **Muscle preservation in early stages = future protection** In prediabetes, fatty liver, and borderline BP, preserving muscle means stopping metabolic progression. This stage is a golden opportunity for intervention.
4. **Losing muscle in advanced stages is dangerous** In long-standing diabetes and heart disease, muscle loss (sarcopenia) increases. Less muscle means: * Difficult sugar control * Increased fall risk * Slower recovery Here, muscle training becomes even more crucial.
5. **Just looking at weight is wrong** If the scale goes down but muscle also decreases, metabolism slows down. Weight loss ≠ Metabolic health.
6. **Just walking isn't enough** Walking is essential, but without muscle stimulus, long-term insulin protection isn't achieved. Strength stimulus provides metabolic stability.
7. **What happens if you have less muscle?** * Lower resting metabolic rate * Increased fat storage tendency * Higher post-meal sugar spikes * Lower energy levels Metabolism feels sluggish.
8. **How to preserve muscle?** * 2-3 times a week resistance stimulus * Adequate protein intake * Adequate sleep (for muscle repair) * Avoid prolonged inactivity (We will do a detailed post on this separately.)
**My clinical opinion:** When improving metabolism, don't just focus on reducing fat. Preserve muscle. Muscle is metabolic insurance.
