Fasting & Muscle Growth: What You Need to Know

When done correctly, fasting can support muscle growth, but it requires careful planning. Here’s how fasting interacts with muscle-building processes:

1. Hormonal Benefits

• Increases Growth Hormone: Fasting naturally boosts human growth hormone (HGH), which plays a crucial role in muscle repair and growth.

• Enhances Insulin Sensitivity: Improved insulin sensitivity helps with nutrient absorption and muscle recovery.

2. Protein Synthesis & Muscle Maintenance

• Risk of Muscle Breakdown: Extended fasting periods without proper nutrition can lead to muscle loss.

• Nutrient Timing Matters: Consuming enough protein and calories in your eating window is crucial for muscle retention.

3. Performance & Strength Training

• Fast vs. Fed Workouts: Some individuals perform well training in a fasted state, while others may experience fatigue.

• Pre-Workout Nutrition: If lifting heavy, consuming amino acids or protein before exercise can prevent muscle breakdown.
