Love the new thread. I've struggled with health my whole life. Weight is a simplistic measure for health, but correlates fairly well and I've yo-yo'd all over the place in my adult life.
I was probably a no-muscle 235 when I graduated high school. Dropped 50 pounds in four months for a new job by basically strapping myself to a Planet Fitness treadmill, and I was like a dog on roller blades trying to run outside or look athletic. I was skinny, but I looked weird (still no muscle), and gained it all back and then some. It was gradual, but there came a time in graduate school I looked in the mirror, stepped on the scale, and saw it was 312. I wasn't happy.
I got down to 245 by the time I graduated, but then moved for a post-grad job and was traveling a lot, was back up to 275 last December.
I'm trying to do it right this time. I'm on a pretty strict high-protein and low-calorie diet (track everything I eat), go to a very difficult Cross Fit gym five days a week, and am gaining muscle a little faster than I can lose fat right now. I'm at 263 as of this morning. I'm really hoping to get down to 212, so that I can officially say I lost a hundred pounds. That'd be really cool.
Of course, then I'll have to deal with a transition, because I'm moving again this fall. Moving (and hard transitions) has been my bear trap before.
