Intermittent Fasting: Benefits, Methods & Complete Beginner’s Guide
Intermittent Fasting (IF) is not a diet, but an eating pattern that focuses on when you eat rather than what you eat. It involves cycling between periods of eating and fasting, allowing the body to rest, repair, and burn stored fat efficiently.
Intermittent fasting is widely used for weight loss, fat burning, blood sugar control, improved digestion, and better metabolic health.
This complete guide explains what intermittent fasting is, how it works, benefits, popular fasting methods, foods to eat, foods to avoid, daily tips, risks, and a sample fasting plan.
What Is Intermittent Fasting?
Intermittent fasting means restricting eating to a specific time window and fasting for the remaining hours of the day.
During fasting:
- Insulin levels drop
- Fat burning increases
- Body repairs cells (autophagy)
- Metabolism improves
How Does Intermittent Fasting Work?
When you eat frequently, the body uses glucose (from food) for energy.
During fasting:
- Glucose stores are depleted
- Body switches to burning stored fat
- Hormones like growth hormone increase
👉 This helps in fat loss, weight control, and improved metabolic health.
