One of the slams one hears or reads about the ketogenic, low carb/high fat (LCHF) diet is that it can't be followed long term and that all diets fail. (That, and 'It will wreck your kidneys' ... 'Your cholesterol is going to go sky high' .... 'You might lose weight but that won't help you if you keel over from a heart attack' ... 'Carbs are required to make glucose so your brain can function properly' ... 'You'll shoot your eye out, kid!')

Wait. That last one is about something else altogether..
