Super SHRED (2013) is a 4-week very rapid weight loss diet, written by Dr. Ian Smith of The Doctors. - Negative energy balance – eat fewer calories than you burn. - Calorie disruption – intermittent fasting, with dramatically varying calorie consumption. - Sliding nutrient density – load up on healthy nutrients while minimizing calorie consumption. - Every meal and snack is listed, with some flexibility. - After 4 weeks, if you still want to lose more weight, move to the regular SHRED diet.
