My gut reaction is no. On the JUDDD website calorie calculator, you have to specify what level of exercise you do and it adjusts your calories accordingly. However, regardless of the exercise level, it rarely goes above 500 cal on a DD. I think keeping cals low on a DD is actually more important than sticking to cals on an UD - it's the fasting element that does the weight loss magic IMO, as well as kicking in all those other health benefits.
