overeating seminars

I have been watching the overeating seminars and loving them. The Intermittent fasting I am familiar with and love it, I did have 2 question coming out of that though. In her protocol list of food dairy wasn’t really addresses? Do you think it is harmful for weightless and should be avoided? It might be one of those things where everyone is different but I am curious! Also, being fat adapted, she said it made us insulin sensitive. I have noticed that only eating one meal a day is causing my blood sugar levels to be higher after the meal is this normal being fat adapted?

thanks so much!
