If we think logically, then it may not seem harmful to combine the two diets, as keto is associated with limiting food intake, and the interrupted person must limit the time interval. They do not overlap in any way.
But experts say that’s not a good idea. First of all, keto is a restrictive diet, which means that the body is already missing the necessary nutrients. Pairing it with intermittent fasting can put more stress on your body, which can have major consequences. The predominant experience can lead to mood swings, irritability and fatigue.
Also, according to some studies, weight loss due to keto remains for a short time. But maintaining a diet can have a positive effect on weight, triglycerides and blood glucose levels.
Combining keto with an intermittent may or may not work for some. It can be more harmful for pregnant women and people suffering from chronic diseases.
