Drinking cold water can burn calories even when you’re inactive.
According to a recent study in the International Journal of Obesity, an Israeli research team found that drinking cold water elevated the burning of calories in overweight children.
In this study 21 overweight and obese but otherwise healthy children came to the research facility in the morning, after at least 12 hours of physical inactivity and complete overnight fasting. During this time they were not allowed to drink any water. The children were then given 10 ml kg-1 based on their body weight of water with a temperature of 4 degrees Celsius. The amount of calories the children burnt was measured before and after drinking the water.
The researchers noted that the amount of calories burnt after drinking water increased by 25% than before drinking it.
This weight loss was attributed to the effect of water has on the production of heat in the body.
Researchers concluded: “Consuming the recommended daily amount of water for children (6-7 glasses) could result in an energy expenditure equivalent to an additional weight loss of about 1.2 kg per year.
This is one good reason for drinking more water over our hot summer.
