A can of beer (350ml) contains about 143 calories, which is equivalent to a bowl of 7-minute full rice, but two-thirds of the calories come from alcohol, which has become the energy source. In other words, beer does not contain high fat that makes people fat, but beer can promote the secretion of gastric juice and increase appetite! So when drinking, we usually eat a lot of high-calorie dishes, which increases the absorption of fat and so on. Therefore, in fact, the reason for getting fat after drinking beer is not alcohol, but appetizers, and unrestrained overeating is the real reason for getting fat. In this way, don't eat too much high-calorie food when drinking beer, which can not only produce satiety, but also not accumulate too much fat, and can achieve the purpose of losing weight. The harm of drinking on an empty stomach is quite great. Because if there is no food in the stomach, wine will directly stimulate and erode the gastric mucosa and muscularis, destroy gastric acid, inhibit the secretion of various digestive enzymes in the gastrointestinal tract, slow down gastrointestinal peristalsis, and easily cause nausea and vomiting, abdominal pain and bloating, loss of appetite, indigestion and constipation. At the same time, drinking alcohol on an empty stomach can quickly absorb alcohol, which has great influence on organs and tissues such as brain, nerve, muscle, heart, liver and kidney, and can lead to dizziness, tinnitus, listlessness and fatigue.
