Yes it can be very successful in the short term, if you have no distractions. I guess that personally, I would just prefer to stay lean year round so there’s no need to “push it” towards the end of a diet.

For example, IF+Keto just meant that my hunger was not existent, and pounding down a load of steak and chicken instead of carbs will result in you feeling very full (calories equated).

But I agree that it’s just a short term thing and people can’t stick to it.
