It's a tool, and for some people tracking calories and workouts is important. I find it funny that people shit on those that are trying to improve themselves.

Edit: I have a bodybuilder friend that tracks everything he puts in his body down to the milligram and every step and workout including reps. Is he a sad individual? I have another friend that needed both hips replaced and gained a couple pounds and is tracking their information. Are they sad? Sorry but dude, let people enjoy things and do things that don't hurt others.
