I think that intermittent fasting works best with a keto diet. I used to be like you. I was hungry as soon as I woke up in the morning. The idea of skipping breakfast seemed impossible. But combining intermittent fasting (eating from 10 am to 6 pm) with a keto diet (dropping all refined carbohydrates and starches), not only can I skip breakfast with ease, but I can do my weightlifting routine (an hour or more) before eating anything. A keto diet brings insulin under control, which allows the body to access body fat for energy. I believe this is why I am no longer half as hungry as I used to be. If you carry only five pounds of body fat, that is 17,500 calories, which is more than enough to cover not eating for the first 4–6 hours of the day. Another thing about many nutritional studies is that they are conducted using a “normal” diet (laden with carbohydrates), which means that they don’t necessarily apply when one switches to a keto diet and drops the carbs. Probably the best book on this topic is “The Obesity Code” by Jason Fung, who also has a number of articles right here on Medium.
