If you’re looking for a sustainable and flexible way to fast, the 5:2 Diet might be exactly what you need. Unlike daily fasting plans, this method offers structure with breathing room — perfect for those who want results without rigid rules. Let’s break it down.
What Is the 5:2 Diet?
The 5:2 Diet is a type of intermittent fasting where you eat normally 5 days a week, and restrict calories to 500–600 on the other 2 non-consecutive days. It’s also called “The Fast Diet.”

Example Schedule:
| Day | Plan |
