I’m a bit confused about these. My doctor will always say don’t skip a meal and he will always remind me “An apple a day keeps you from the doctor” so if skipping meal is a bad habit, why do experts and professional nutritionist say intermittent fasting is healthy?
In every field, there will always be different opinions about something. I see this more especially in health topics. So, you could listen to your doctor if you want. For example, I don't support the idea that skipping a meal is good. Because it affects our immune system badly too.
