So I finished jogging yesterday (only four miles, but a good start) and tossed my info into MyFitnessPal for analysis. A guy my size burned about 500 calories from that. I was all happy and proud - until I looked up towards my meals and found that I essentially only burned off my lunch. That got me thinking, I put in an hour of effort and I'm certainly sore today, but I could have essentially accomplished the same goal with two fingers and 30 seconds. I haven't made any decisions yet, this wouldn't be a daily event, and I'm certainly not going to quit exercising in favor of this frankly lazy and dangerous solution. But what if I were to purge maybe once or twice a week after eating something particularly full of calories as a treat (like a piece of chocolate or something)? Would that be so dangerous?
