A friend did try the keto diet thing but she got out fast. Her complaint was it was too expensive to keep up. I think they gave certain products to buy to help her along.

I want to clarify something, the ketone diet stuff means eating only fatty foods? You don't have to eat any specially made food or substitute?

My friend wabts to reduce her weight and the size of her stomach too, so I don't know. Is this process good for getting rid of fat in the body?
