If the amount of calories produced by drinking alcohol exceeds the amount consumed, you will gain weight even if you don’t eat or drink. Wine calories mainly come from alcohol, also known as ethanol. 1 gram of ethanol can provide calories for 7Kcal, second only to fat. After drinking, the calories produced by alcohol will inhibit the consumption of carbohydrates and fats, increase the synthesis of fat, and cause fat to accumulate in the body, especially in the abdomen and liver. Even if you don’t eat the food, you will still gain weight when the calories produced by alcohol are more than what your body needs to consume. Alcohol consumption is not recommended on a daily basis. For occasional sips under special circumstances, you can reduce the intake of some foods to avoid consuming more than you consume. Prolonged alcohol consumption, much less alcoholism, is not recommended.
