What Is Intermittent Fasting?
Intermittent fasting (IF) is an eating pattern that cycles between periods of fasting and eating. Unlike traditional diets that focus on what you eat, intermittent fasting focuses on when you eat. It does not specify which foods to eat but rather when you should eat them.
Research has shown that intermittent fasting can help with weight loss, improve metabolic health, reduce inflammation, and may even extend lifespan.
Popular Fasting Methods
There are several popular approaches to intermittent fasting:
| 16:8 Method | Fast 16 hours, eat within 8 hours daily |
| 18:6 Method | Fast 18 hours, eat within 6 hours daily |
| 20:4 Method | Fast 20 hours, eat within 4 hours daily |
| 5:2 Diet | Eat normally 5 days, restrict calories 2 days |
| OMAD | One Meal A Day — eat one large meal per day |
Health Benefits of Fasting
Intermittent fasting offers numerous potential health benefits supported by scientific research. During fasting, your body undergoes cellular repair processes and adjusts hormone levels to make stored body fat more accessible.
Benefits may include improved insulin sensitivity, reduced inflammation, enhanced brain function, and cellular autophagy — a process where cells remove damaged components.
