Yah Evo, I lost 125 in the first year, 315-188. But... I shouldn't have. Your skin will be much happier if you lose maybe a pound a week.
I just jumped into non-stop hardcore exercise. I never even had a fill, not even a first. I jumped into MMA training, weight lifting, and paintball, lol. If it's not something that's absolutely fun to you, you're not going to want to stick with it.
The most fortunate thing of my life has been getting to the point where I wait all day to be able to go workout or spar. I absolutely love it because I have good friends to do it with and it's a lot of fun.
But man, it sure is hard to do it on no carbs. I've been there, you just feel... like shit really. I live on Protein shakes, 95% lean ground beef, fish, broccoli, and fish oil pills. But I feel excellent. It's ok to spike your GI carbs (sugar carbs) right before a workout, the insolin spike will help deliver nutrients to your muscles better, and give you energy to get gains from the activity. No sugar added grape juice - half a cup - about 20 minutes before your workout will make the whole thing a lot less painfull. The serotonin spike from sugar probably has something to do with that, but who cares : P. You'll burn it off.
Good luck bud. I plateu'd at 230 for a few weeks and it was a horrible feeling. I thought I was just destined to never get any smaller, and no one could tell me any different. It'll pass bud.
If you don't want your skin to look like melting wax when your done, stick with that 1lbs a week. Trust me.
