Atkins is not good. It works in the short term, but you're shooting yourself in the metaphorical foot. Have you ever seen someone who's been on it for a long time go back to eating like a normal person? It's like watching a balloon expanding.
Use carbohydrate and calorie cycling instead. All the benefits, none of the shit. Oh and don't starve yourself. All you're doing is losing water and muscle and trashing your metabolism.
