The things that you drink are just as important as what you eat. Having alcohol every now and then is fine, but losing belly fat is going to be hard if you drink beer or sweet alcohols every day. People who consume beer tend to have a pear-shaped body, especially as they get older. Alcohol also puts stress on the liver, which will have to work hard to clear out all the toxins. This keeps your body from being able to build muscle. Alcohol consumption should be like junk food consumption, 10% of the time. Maybe just Friday and Saturday night, and normal consumption, not getting drunk. Other than that, you should stick to water, water with lemon, green tea, and so on.
