"Drinking water to lose weight" is popular among the people again. A few days ago, Zeng Liangju, an associate professor in tongji hospital of Huazhong University of Science and Technology, warned everyone that "drinking water to lose weight" is a dangerous rumor! Drinking more water will increase the burden and endanger health. "Drink a large glass of 65,438+0,000 ml of cold boiled water or mineral water before or during meals ... If you insist on taking more than 5,000 ml of water every day, you can achieve the effect of losing weight and detoxifying." This is a "diet prescription" that some people prescribe for themselves at present. Its "theoretical" basis is that human metabolism consumes calories. If you consume more than 5000 ml of water every day, your calorie intake is more than twice that of normal people; And the satiety of drinking water will affect the food intake. In this regard, Associate Professor Zeng Liangju pointed out that drinking too much water will dilute the blood in blood vessels due to osmosis, resulting in a decrease in the concentration of oxygen and nutrients contained in blood. In order to meet the energy supply of the body, the heart must increase its working intensity, which leads to an increase in the heart load. If this happens for a long time, it will do great harm to health, especially to anemia patients. Experts pointed out that if you drink plenty of water every day to lose weight, it will lead to "water poisoning" within one month. Drink plenty of water, the body must excrete excess water through urine, and the discharged water contains important electrolytes. If it lasts too long, the sodium-based electrolyte in the body will be diluted. At the beginning, there will be symptoms such as fatigue, weakness, backache, chills, rapid heartbeat and skin loss of elasticity. In severe cases, convulsions, confusion and coma may even occur. In addition, drinking plenty of water can cause visceral edema. Because "water flows downwards", excess water will gather in the waist and lower limbs, causing edema in the waist and lower limbs.
