If you can deal with cutting your carbs down, I'd say give Keto a shot. I did Keto for 6 weeks last year, and lost a lot of waterweight, and tightened up quite a bit.. I only stopped so I could drink more beer...not the best reason..
Google "The Ketogenic Diet" by Lyle McDonald... long, but good read with diet advice, workout plans, and a bunch more good stuff...
