I followed the diet for three weeks many years ago and got good results. However, I don't do well on ketogenic diets, I feel like crap. Also, as with most ketogenic diets it can cause insulin insensitivity and you can suffer from a rebound weight gain if you increase your carbs too quickly after coming off the diet, which is what I experiencedI would increase your carbs to 10% the first week off and then add 10% per week until you reach your desired percentage. I've found the most effective diet for my metabolism is to decrease carbs to around 200g per day, that way i don't feel like total crap.
