Accutane and Ketogenic eating lifestyle?

This is hard to answer without knowing more specifics and being your doctor. But in general, Accutane is best absorbed with higher fats and proteins, so as long as your body is not running in ketoacidosis and showing your liver and kidneys are already working in overdrive, then I wouldn't necessarily have an issue with the diet. Your doctor(s) need to discuss this more with you. A general consensus isn't going to work well here because we don't know all your history and levels.
