Well, once you've finished "eating" your body fat, you can't sustain the calorie restriction. But at that point there's no reason too. For those of us prone to insulin resistance, we have to continue to eat low-carb to avoid putting the weight back on. (Very similar to how an alcoholic who's gotten sober has to continue to avoid alcohol.) But we don't need to have a caloric deficit anymore.
