For 4,000 years, Asians have regarded green tea as more than just a beverage. It was used as herbal medicine and treatment for everything from headaches to depressions and even to weight loss.
Researches have been conducted over the last few years to identify what compound present in green tea makes it a potent health drink. The scientists have found that the tea contains several antioxidants which are responsible for many of green tea's health benefits, including a weight loss benefit.
A research study by American and Swiss scientists on the weight loss benefits of green tea was concluded and the results of which were published in the American Journal of Clinical Nutrition and Urology. During the course of their study, they have found that green tea contains certain compounds that contribute to losing weight.
Lead researcher, D. Abdul Dulloo said in a press release that there are only two ways to achieve weight loss - either reduce energy intake or increase energy expenditure. Green tea it seems, has compounds that can increase the body's normal metabolism rate which is where it gets its weight loss benefit.
At the University of Geneva, where the study was conducted, Dr. Dulloo and his colleagues experimented on ten healthy young men. They theorized that the main contributor to green tea's helping remove those extra pounds is its caffeine content. To test this hypothesis they placed the study's participants on a typical "Western" diet which is about forty percent fat, forty-seven percent carbohydrates, and thirteen percent protein.
Thrice everyday, the researchers measured their subjects' energy expenditure (the measurement used in determining the number of calories burned in 24 hours) and monitored their respiration quotient to find out how well they utilized their carbohydrates, proteins, and fats.
