Q: How much should I eat on the Up Day?
A: There is no required calories to eat to make this diet work. The point of an up day is to reduce stress, diet fatigue and to increase freedom from the anxiety of restricting food every day. You can eat until you are full but do not over eat. The calorie counter (on the JUDDD website) is to estimate the number of calories to eat on the down day. You do not have to consume all the estimated calories on the up day.
