Hey Man;
I know this isn't what you wanna hear, but diet and cardio done properly WILL cause you to lose weight. Since football got done, I haven't even been trying to cut, just busting my butt lifting and doing plenty of cardio. Along w/ a sound diet, I've lost 21 lbs in just over 2 months. W/ GREAT increased in strength. All it really took was eating well. I'm currently eating the best I've eaten in my life, and I'm 24. There have been times where I've trained harder, but haven't gotten nearly the results I've been lately, simply because my diet wasn't as good as it is now.
Lift heavy, run fast, eat well. It's as simple as that. And as someone else already mentioned, lay off the booze. Having A FEW beers once every couple weeks won't kill you, but if you're getting blasted every weekend, it will not help your physique at all.
Unfortunately, as w/ most people, you probably AREN'T going to be talked out of doing some form of juice. It's gonna be your decision. If you do decide to do something, be sure to research everything you can about it. Best of luck to you.
