The extra carbs don't make you lose extra weight. The carbs are there as fuel for an active lifestlye.

The CKD was designed for bodybuilders conducting intense weight training. Without carbs, intense activity lasts 3 workouts and then things go flat.

Try a weekend carb up, but be sure to do a workout every morning for the first 3 days .after the carb-up. Also, I strongly advise weight training along with it, but that's your decision.
