Interesting discussion, I'm kind of on the opposite program. I was up to like 235 five or so years ago, slipped a disc in my back and decided I needed a drastic reordering of my priorities. I hover around 160 now, as low as 150 over the summer. Basically done via calorie restriction and body weight exercises because I hate the idea of going to a gym (though I've never actually gone, so maybe it's way doper than I think). I was pretty ripped this summer, but in like a lean way, rather than a huge way. Basically large numbers of low weight reps - pushups, pullups, situps, crunches, planks, and that sort of shit. Running few times a week (maybe averaging 15 miles a week), biking to/from work and for all my errands, and then just actually keeping track of my eating, which is definitely difficult at first.
I'm skeptical of starting to take any kind of supplements as I don't think it's heavily regulated enough and who knows what you're really getting. Anyways being lighter on your feet has definitely helped my skating. I haven't gotten hurt nearly as much as I had been, and when I do get hurt, it's not for nearly as long, since I don't have an actual-medium-sized-boulder's-worth-of-torque acting on my shitty ankles.
