For a long time, drinking water has been thought to help lose weight. In fact, 30–59% of US adults who try to lose weight by increasing their water intake. Many studies show that drinking more water may benefit weight loss and metabolism. This article explains why drinking water can help you lose weight.
Some people claim that drinking water before a meal reduces appetite. There actually seems to be some truth behind this, especially for old people.
Studies of elders have shown that drinking water before each meal may increase weight loss by 2 kg (4.4 lbs) over a 12-week period. In one study, middle-aged overweight and obese participants who drank water before each meal lost over 44% weight, compared to a group that did not drink more water before meal. Another study also showed that drinking water before breakfast reduced the amount of calories consumed during the meal by 13% .
Although drinking water before meal may be very beneficial for middle-aged and older people, studies of younger individuals have not shown the same impressive reduction in calorie intake.
Drinking water increases the amount of calories you burn, which is known as resting energy expenditure. In adults, resting energy expenditure has been shown to increase by 24–30% within 10 minutes of drinking water. This lasts for at least 60 minutes. One study of overweight and obese children found a 25% increase in resting energy expenditure after drinking cold water.
A study of overweight women examined the effects of increasing water intake to over 1 liter (34 oz) per day. They found that over a 12-month period, this resulted in an extra 2 kg (4.4 lbs) of weight loss. Since these women didn't make any lifestyle changes except to drink more water, but still these results are very impressive.
Additionally, both of these studies indicate that drinking 0.5 liters (17 oz) of water results in an extra 23 calories burned. On a yearly basis, it sums up to roughly 17,000 calories — or over 2 kg (4.4 lbs) of fat.
Since water is calorie-free, it is generally linked with reduced calorie intake. This is mainly because when you drink more water, chances are that you will drink less beverages, which are often high in calories and sugar. Observational studies have shown that people who drink mostly water have up to a 9% (or 200 calories) lower calorie intake on average.
Drinking water may also help prevent long-term weight gain. In general, the average person gains about 1.45 kg (3.2 lbs) every 4 years.
In summary, drinking more water is conducive to weight loss. However, with increased water pollution, we should pay more attention to water quality and water treatment. If every household can be equipped with water treatment devices, such as ozone kitchen water purifiers, ozone water sterilizers, ozone water filters, etc, it can greatly improve the quality of our drinking water.
