While I do appreciate the benefits of a ketogenic diet, I don't think it's for everybody. This could work great for people who are "out of balance", i.e. if you have excess body fat, it might be beneficial to switch to a metabolism that uses your fat stores (rather than continuing to add to it). I don't think it's a good idea to put your kids on a ketogenic diet (unless they're epileptic and don't respond to treatment) because it is known to stunt growth in children.
