Alcohol is a big hindrance when one tries to lose weight. A glass of wine or beer may contain even more calories as compared to a full sized chocolate bar. It makes the body lethargic and thus fat accumulation is the end result. If you drink heavily then you need to immediately change this habit. By cutting the alcohol intake, the body will react in a different manner. You will feel more active and the metabolism will also improve. So, alcohol is one of the most essential things to avoid if you are planning for weight loss.
