1, drinking water can burn more calories.
Drinking water will increase heat burning. In adults, studies have proved that drinking 500 ml of water will lead to an extra 23 calories burning.
A study of overweight women examined the effect of increasing drinking water to more than 1 liter every day. They found that within 12 months, this resulted in an extra 2kg weight loss. These results are impressive because they have not changed any lifestyle except drinking more water.
Several other studies monitored overweight people who drank enough water every day for several weeks, and their weight, body mass index (BMI), waist circumference and body fat decreased significantly. Drinking cold water at the same time is better for weight loss. When you drink cold water, your body will consume extra calories to heat the water to body temperature.
2. Drinking water before meals will reduce appetite.
Current research has confirmed that drinking water before meals is good for weight loss, especially for middle-aged and elderly people.
There is a study in the United States, which divides adult overweight and obese people into two groups:
(1) Low-calorie diet every day+500ml of water before meals;
(2) Simple low-calorie diet group. The results showed that compared with the group that didn't drink water, the overweight and obese middle-aged participants who drank water before each meal lost more than 44% weight. Another study also shows that drinking water before breakfast will reduce the energy intake at breakfast.
3. Water itself contains no calories.
The three major sources of calories are carbohydrates, protein and fat, but water does not contain these three, so water itself does not contain calories. If you choose to drink water instead of other drinks, it is obvious that you will reduce your calorie intake, because drinks usually contain high calories and sugar, and the average calorie intake of most people who choose to drink water can be reduced by up to 9% (or 200 calories).
Generally speaking, ordinary people will gradually gain weight as they get older, but drinking water may also help maintain their weight:
Adding 1 glass of water: increasing the daily water consumption by 1 cup can reduce the weight gain by 0. 13kg.
Replacing other drinks with water: Replacing a sweetened drink with 1 glass of water can reduce the weight gain by 0.5kg in 4 years.
It is especially important to encourage children to drink water, because it helps to prevent them from becoming overweight or obese.
More than a decade ago, there was a school-based study aimed at reducing the obesity rate by encouraging children to drink water. They installed drinking fountains in 0/7 schools in Germany/KLOC, and provided courses on water consumption for students in grades 2 and 3. After one school year, the risk of obesity decreased by 31%in schools with increased drinking water.
How much water should you drink?
We have all heard the saying "drink 8 glasses of water a day (about 2 liters)", but this is only a general guide. Like many things, the demand for water depends on the individual. People who often sweat or exercise may need more water than people who are less active. Older people and nursing mothers also need to monitor their water consumption more closely.
You will also get water from many foods and drinks, such as tea, coffee, meat, fish, milk, especially vegetables and fruits. (PS: The domestic standard is 3 liters per day for adult men and 2.7 liters for women, and the water in it includes drinking water and water in food. )
If you find headache, bad mood, frequent hunger or inattention, it may be a sign of mild dehydration. Drinking more water will help solve these problems. Of course, drinking more water does not mean drinking water without restraint.
Water is really helpful to lose weight. It has zero calories and can help you burn more calories. It can even suppress your appetite when you eat it before meals. When water is used instead of sugary drinks, the benefits are even greater, which is a very simple way to reduce sugar and calories.
