🕒 What Is Intermittent Fasting?
Intermittent fasting (IF) is an eating pattern that cycles between periods of eating and fasting. It’s not about what you eat but when you eat. The goal is to allow your body to enter a fasted state, which can boost fat burning, hormonal balance, and cellular repair.
🧠 How It Works
When you eat, insulin rises to help process food. During fasting:
-
Insulin drops, allowing fat burning.
-
Your body switches to stored fat for energy.
-
Cell repair processes increase (like autophagy).
-
Human growth hormone (HGH) increases, aiding fat loss and muscle gain.
