This is going to be really short just cause I'm stupidly tired. I did OK today i must have burned 200 cals easily most likely more but I'm not sure.
Tip: If you want something really bad then just take two or three bits of it. That way you taste it and your less likely to binge of the whole thing later. Remember 30 calories of a couple bites is better then 3000 calories of the whole thing.
