That's surprising to me and interesting how different feelings drive us. I love my body, I marvel at its abilities and want to thank it for looking after me by treating it right and not abusing it. I mostly don't track what I put in it, although I do weigh and chart it. If I hit a certain weight (79 kgs, 174 lbs) I track what goes into it and ramp up the cardio until I'm back down to 76 kgs. Of course, vanity is a huge motivator, I realise I'm much more attractive when my body's in shape and I want to leverage that. I'm not sure I could manage to be 'always on' like you seem to be. You're probably in better shape than me though so I suppose it's a spectrum all the way from this fat dollop to guys that are perfect physical specimens. I know which end of the curve I'd rather be at.
