re: OT Workout crew: What am I doing wrong?

Current diet is flexible, but again falls into IIFYM. I'm currently at 120g fat, 320g carbs, 160g protein. The carbs is what is tough because I'm doing my best to eat as many "good" carbs as I can over "bad" carbs.

Gained five pounds over the last 6 months.

And here's where I'm sure everyone will hate on me, but I'm in the gym 5-6 days a week doing crossfit. Yes I know many people will say stop doing that and do something else, but for my personality and fitness knowledge, it works for me. And by works for me, I mean it is the only program I've ever found that I actually enjoy and will commit to long term. When im in the gym on my own I am the first to admit I feel a little lost. I used to run as well (did the Boston marathon last year. Yeah, subtle brag but that shite hurt so I earned it ) but that tends to get cut out during the winter in New England.
