I too am a bit of a self-experimenter. I know this approach isn't for everyone and it does carry an element of risk. I've experimented with a ketogenic diet for around eight years now. I sometimes lapse, mostly during holidays, but I always return to the diet as part of my day-to-day routine. I find that I can easily lose the several extra pounds that I put on during the holidays within around two weeks of starting up the keto diet again. I suppose it helps that I really enjoy the type of food I get to eat by following this regimen. Many of the foods I like are quite high in protein and fat. I do miss carbohydrate-rich foods such as pizza and pasta but I think that loss is outweighed (sic) by the benefit of being able to each rich food and still keep my weight under control. It goes without saying that I have to avoid sugary foods but I don't have much of a sweet tooth and I can still enjoy things like good dark chocolate, in moderation.
