Drink Water to Lose Weight

Wednesday, February 20th, 2008

I knew thirst could masquerade as hunger… one more reason to keep hydrated but I also heard that drinking cold or chilled water could boost your metabolism. Drinking cold or chilled water for the purpose of raising your metabolism is called, Water-Induced Thermogenesis research.

Apparently the colder water can cause a rise in metabolism and contribute to the increased energy expenditure. Researchers found that drinking a 16 ounce glass of cold water increased the metabolism of volunteers by as much as 24 percent over their normal metabolic rate, with this increase lasting as long as 90 minutes. The increase occurred within 10 min and reached a maximum after 30–40 min.

The slight increase in energy used is because of the energy used by your body to warm the water during digestion..

This means that a man who drinks an extra 50 ounces of cold water daily, in theory could burn an extra 17,500 calories annually!

The study author, Jens Jordan, M.D. and the other researches concluded that the thermogenic effect of water should be considered when estimating energy expenditure, particularly during weight loss programs.

How cold was the water in this study?

“About 40% of the thermogenic effect originated from warming the water from 22 to 37 C.”

Go have a cold one! :-)
