Intermittent fasting (IF) doesn’t specify which foods you should eat but emphasizes when you should eat them. Still, in order to maximize the potential health benefits of IF, it’s important to stick to nutritious whole foods and beverages during your eating periods.
Practicing IF together with another diet plan is compatible. However, if both IF and a diet are new to you, it can become too challenging and overwhelming to start two regimens simultaneously.
For example, combining a low-carb or ketogenic (keto) diet with IF recently has become very trending. Not only is keto very restrictive in terms of what products are allowed, but it also switches your body from burning glucose as a fuel to burning fat instead. So, it is recommended to get a good handle on keto before adding an intermittent fasting regime.
