Physical effects abound. Mostly, you'll lose weight and your skin will look amazing. "When you stop drinking and change nothing else about your diet or level of activity, you're likely to lose weight," says Adoni Ben-David. "We all know the formula, calories in versus calories out; and alcohol contains lots of calories."
"Alcohol is also a diuretic, meaning it causes water to exit the body," she continues. "One of the things it does is it decreases the production of a hormone that helps the body absorb and hold water. As time goes by, being dehydrated has noticeable effects, such as dry-looking skin, dandruff, and eczema. Once you quit alcohol, your skin will thank you."
