Eat This at Night to Rebuild Muscles While You Sleep – Doctor Explains the Science | Dr. William Li

, Dr. William Li breaks down the fascinating science of how the right foods eaten before bedtime can trigger powerful muscle repair, fat metabolism, and hormonal balance while you rest.

You will discover the connection between nighttime protein intake, growth hormone release, and amino acid delivery that helps protect your muscles against aging, improve recovery after exercise, and support lean body composition.

Dr. Li explains why most people unknowingly sabotage their overnight recovery by skipping evening nutrition — and what to eat instead for sustained repair and energy. You will also learn the exact timing, food types, and lifestyle protocols that naturally enhance your metabolism while you sleep.

This is functional nutrition at its finest — rooted in science, simple to apply, and transformative for anyone serious about muscle health, longevity, and vitality.
