Sure, but how much effect do all those "side effects" have in comparison to a significant calorie deficit or surplus? How applicable are those effect to the average person who wants to keep their eating to something relatively simple?

Do you think that any of those effects will be enough to maintain your weight if you consistently eat a 500 calorie surplus?

My issue is that a lot of people start doing "intermittent fasting" (less than 3 days) thinking they can eat all they want during the eating period, and that they will benefit from the fasting health effects shown in mice studies, but neither is true.
