You shouldn't feel like you have to restrain yourself. They have become a bane on our country's(U.S.) healthcare.
I understand letting yourself go a little. I really do. When I roll out of the military for good -- probably when this next term is up -- I'm never running again unless something's chasing me. I empathize with the squishy-in-the-middle types. I'm sure food is more fun and life is easier overall at 20% bodyfat. You're up at 7 having fried eggs and Danish, and half and half in your coffee, instead of running at 4:30 in the sideways freezing rain. You're having an after-dinner drink instead of a pre-bed protein shake. Your free evenings are spent in an armchair instead of at the gym. I have no problem with this.
It's the people hauling around an extra 100-200 lbs,
who are doing nothing about it, that make me want to go on a ball-punching spree. When I'm at the store and there's a woman who's gotta be 300 lbs. in line and she has a cart full of soda, chips, and snack cakes. Worse if she has a few fat kids with her. I see this all the time and it actually makes me mad. Not because they're a drain on the system (they are), not because I'm better than they are in some way (I am; to quote Rippetoe: "Strong people are harder to kill than weak people, and more useful in general"), and not because they're hurting and possibly killing their children (they are), but
because they know what's wrong and they know how to fix it and they're not doing it.
Few things make me happier than seeing an overweight person destroying themselves at the gym, or even out for a walk or a jog when I'm running. Man, watch a fat guy come staggering and wheezing across the finish line at a 5K when you're already in the beer garden cashing in your second drink ticket. That's inspiring.
Do it. Fix yourself. I'll help: I'll pray for you, I'll cheer for you, I'll even give you advice if you ask.
