How tall are you?
Yeah, it's hard. I turn 40 in May and wanted to be in my best shape since college. That was my motivation or else I would be coming out of a 4-5 day long weekend bender myself. And that's every weekend.
I'm 5' 11". I'm not really fat but I've got a gut now when I usually don't and I'm quite out of shape both cardio and strength wise. Mostly I just need the nice weather to get here quickly and then everything will more or less take care of itself. I'll start doing more and should slim down.
I've done Whole 30 before, at least half-assedly. My wife did it full throttle, I still drank and didn't worry about meals when I was away from home. I'm generally against most fad diets, even though I tend to shed weight quickly if I do it, I can go a week or two without carbs and probably drop 10 lb. I find that I enjoy food too much to really get into many diets. I am not much for junk food or desserts or snacking, so even if I'm eating a lot of heavy meals, I don't eat all that horribly.
