I'm having the same issue. I recently lost 50 lbs and hit a very long plateau that I'm really frustrated with. Now the weight has started to inch upwards and I need motivation and willpower to keep going.
I keep fruits and veggies at my desk at work to keep from snacking on bad stuff when...
I don't remember what the exact quote is, but it's something like...
Suck in that air, it's free!
I always laugh at that one because I can imagine everybody breathing super hard after that workout.
