Thanks for the swift reply, Lisa. I'd always wondered if it was essential to go through induction, as basically, in the end, Atkins turns out not to be very different from any other eating plan, just that you eat more fat and less carbohydrates. In fact it is a calorie-control diet with the main difference being that because it's highly structured (you keep proteins and fat stable, only changing the intake of carbs), its easier to calculate how much you can eat before gaining weight.
