What is 5:2 Diet (Weekly Fasting)?

The 5:2 diet is a weekly fasting approach. You eat normally for 5 days and significantly reduce calories (500 for women, 600 for men) on 2 non-consecutive days. It's not a complete fast but a severe calorie restriction.

How It Works

On fasting days, the low calorie intake keeps insulin low and promotes fat burning without requiring a complete food abstinence. The two low-calorie days create a weekly calorie deficit while maintaining daily eating habits.

Benefits

🔥

Enhanced Fat Burning

Your body shifts to burning stored fat for energy during the fasting window.

🧠

Mental Clarity

Many people report improved focus and cognitive function while fasting.

Stable Energy

Avoid energy crashes by training your body to use fat for fuel.

🔄

Cellular Renewal

Extended fasting triggers autophagy, your body's natural cellular cleanup process.

Who Should Try This?

People who prefer eating something every day, those who struggle with time-restricted eating, beginners who want flexibility, and anyone seeking a sustainable weekly rhythm.

⚠️ Important

Consult with a healthcare provider before starting any fasting protocol, especially if you have diabetes, are pregnant, or have a history of eating disorders.

Sample Schedule

Monday/Thursday: Fasting days (500-600 kcal) → Other days: Normal eating. Space fasting days apart for best results.

Tips for Success

💡 Tips for Success

  • Stay hydrated! Drink plenty of water, black coffee, or unsweetened tea during your fast.
  • Start gradually. If 16:8 feels too hard, begin with 12:12 and work your way up.
  • Break your fast with nutritious foods, not junk food. Your body deserves quality fuel.
  • Listen to your body. If you feel unwell, it's okay to break your fast early.
