How to Effectively Lose my Gut?

Ok so over the last year, I have lost an estimate of around 60-65 pounds (currently weigh 200 lbs). I did this mainly through a combination of walking and using Wii Fit. While I have lost a lot of fat in my face and upper chest area (ribcage up), I still have a pretty thick gut with the ever present love handles. This makes my body look pretty disproportionate and out of balance, like a hybrid of the old body and new body. What would be the best way to burn off the excess fat and fat rolls? Thanks all :D
