How can I get my belly thinner?

I'm 26 years old, 5'11'' and 170 lbs. Although I generally seem thin, my belly is recently not flat as it was a couple of years ago. Im very much into the sports (Basketball, Volleyball, Soccer etc.) and have the ability and stamina to keep on doing sports, but nowadays I can not find much time for sports because of workload. And worse, I drink alcohol (espceially Beer) several times a week....So do you have any advice for me to get my belly thinner without quitting alcohol?

How can I get my belly thinner?
First alcohol makes u fatter u have to no matter what if u want to get your belly thinner u have to quit!!But if u eat these foods i listed your belly will get thin in about i month!!or less!!

But u still do not have to quit alcohol if u try this!
Reply:well if you don't really want to quit drinking alcohol, try drinking less of it, and try to fit some exercise in your schedule. I really think that if you quit alcohol it's much better for your health. Replace alcohol with more water, or juice or even diet soda.
Reply:Quit drinking alcohol cause you will get a "beer belly". Do weight training, cardio, look up some toning exercises for your stomach etc. Plus try to eat healthy foods. Diet is very important to lose inches.
Reply:You can only do so much. This is why models even being very low fat will get liposuction. Just be happy it doesn't matter that much.
