Since keto is all about restricting the food intake and intermittent about restricting time intervals, it might not seem harmful to combine them. But scientifically, combining the two can do more harm than good.

First of all, both diets have their shares of pros and cons. Combining the two means double risk, especially for beginners and those suffering from some health conditions.

Secondly, keto is a restrictive diet and following it for a long time may lead to nutrient deficiency and kidney problems. When you pair it with intermittent fasting, you may put excessive stress on your body. The overwhelming experience might lead to mood swings, constipation, irritability and fatigue.

Thirdly, there is no guarantee combining the two diets will work for everyone. We all have different metabolism and different bodies, so naturally, our journey to shed kilos would be unique from others. No two people have the same weight loss journey. What works for one may not work for the other. So, it is not necessary that combining intermittent fasting and keto will help your drop kilos.
