Sihaiwang: many studies have shown that drinking more water is good for weight loss and maintenance. First of all, water will make you burn more calories. According to a study, drinking water increases the amount of calories burned by the body, which is called resting energy consumption. Based on a 0.5-liter glass of water experiment, researchers found that in adults, resting energy consumption increased by 24-30% within 10 minutes after drinking water, and lasted at least 60 minutes.
According to many similar studies, drinking 0.5 liters of water causes about 23 calories to burn. The annual total is about 17000 calories, equivalent to or more than 2 kg of fat. If you drink cold water, the effect will be more impressive, because when you drink cold water, the body will use extra heat to raise the water temperature to body temperature.
Second, drinking water is associated with reduced energy intake and reduced risk of weight gain
Water does not contain any calories, so it is usually associated with reduced energy intake. This is mainly because when people drink water, they naturally reduce the intake of other drinks, and any drink other than water contains sugar and calories, which are usually not low.
Drinking water may also help prevent long-term weight gain.
A recent school-based study aims to reduce obesity by encouraging children to drink water. They installed fountains in 17 schools and provided classroom instruction on water consumption for second and third year students. After a school year, the risk of obesity in schools with increased drinking water fell by 31%. In addition, drinking water before meals can reduce the amount of food eaten, thus reducing energy intake.
We often hear nutritionists suggest drinking 8 glasses of water (about 2 liters) a day. But the number is completely random. In fact, the demand for water is entirely up to the individual. For example, people who sweat a lot or exercise a lot may need more water than those who don't exercise much. Older people and lactating women also need to monitor their own water consumption more closely. According to the study, drinking 1-2 liters of water a day should be enough to help lose weight. And drink more water can help the body to complete the cycle of nutrition, the elimination of toxins and excess water.
