Of course, with ANY "diet", when you go off it and back to bad habits, you regain weight. I mean, if you go on a low fat diet for a year, then go back to a high fat, high carb diet, you'll regain the wait also. Keto is no different.

Keto has to be looked at as a lifestyle change, not a temporary "diet". Really any of them. I come from a family of short, fat Italians. I'm battling genetics. Keto is the only thing that has stabilized my weight over the long term. If I want to maintain a healthy weight, my body requires me to eat a ketogenic "diet". It's just what I've been dealt and it's up to me to live that way, or eat whatever I want and be overweight.
