Drinking water can burn more calories.
Drinking water will increase calorie burning. Studies have proved that adults who drink 500 ml of water will burn an extra 23 calories.
A study on overweight women investigated the influence of drinking more than 1 liter per day. They found that in 12 months, this led to an extra 2 kg 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 losing weight. When you drink cold water, your body will consume extra calories to heat the water to body temperature.
Drinking water before meals will reduce appetite.
Current research has confirmed that drinking water before meals is beneficial to lose weight, especially for middle-aged and elderly people.
There is a study in the United States that divides adult overweight and obese people into two groups:
(1) Low-calorie diet every day+500ml water before meals;
(2) Simple low-calorie diet group. The results showed that overweight and obese middle-aged participants who drank water before each meal lost more than 44% weight compared with the group who didn't drink water. 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 heat are carbohydrates, protein and fat, and water does not contain these three, so water itself does not contain calories. If you choose to drink water instead of other drinks, obviously 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, with the growth of age, the weight of ordinary people will gradually increase, but drinking water may also help to maintain weight:
Supplement 1 glass of water: increasing the drinking water of 1 cup every day can reduce the weight and gain 0. 13kg.
Replacing other drinks with water: replacing a sweetened drink with 1 glass of water can reduce weight and gain 0.5kg in four years.
It is especially important to encourage children to drink water, because it helps to prevent them from being 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 the 17 school in Germany, and offered water courses for the second and third grade students. After one school year, the risk of obesity in schools with increased drinking water decreased by 365,438+0%.
How much water should you drink?
We have all heard of the saying "drink 8 glasses of water (about 2 liters) every day", 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. The water inside 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 helps to solve these problems. Of course, drinking more water does not mean that drinking water is unrestrained.
Water is really helpful for losing weight. It has no calories and can help you burn more calories. Even eating before meals can suppress appetite. When water is used instead of sugary drinks, the benefits are even greater, which is a very simple way to reduce sugar and calories.
