For those two days, you eat 2 small meals of 250 calories each for women and 300 calories each for men. As critics correctly point out, there are no studies testing the 5:2 diet itself, but there are plenty of studies on the benefits of intermittent fasting.

This can also happen when you first start a new fasting schedule. But if you stick with a set intermittent fasting schedule or fasting duration for 2-3 weeks, you should adapt and have similar energy levels during your fasting windows or days as during your eating windows or days.

You might need to eat 1,000 calories or more at one sitting, and as you extend your fasting window, you will have to increase your meal size. To help you adapt to this change, our intermittent fasting meal plan starts with a longer feeding window.

Depending on how long the fast is, you may lose weight. A 3-day water fast will likely result in minimal weight loss from water weight, while a longer fast may result in greater weight loss. Keep in mind that this weight will likely return when you go back to eating your normal diet.
