Green tea has thermogenic properties and promotes fat oxidation beyond that explained by its caffeine content per se. The green tea extract may play a role in the control of body composition via sympathetic activation of thermogenesis, fat oxidation, or both.
What does that mean? Grean tea burns fat.
You might recall this episode of Oprah where Dr Perricone (Author of The Perricone Promise) talks about how grean tea could help you lose 10 pounds in 6 weeks.
Oprah: Now I’ve read in your book that you said if I just replaced coffee with green tea instead, that I could lose 10 pounds in six weeks.Dr. Perricone: Absolutely.
Oprah: Now really. How could that — what is the big deal about this?
Dr Perricone: Coffee has organic acids that raise your blood sugar, raise insulin. Insulin puts a lock on body fat. When you switch over to green tea, you get your caffeine, you’re all set, but you will drop your insulin levels and body fat will fall very rapidly. So 10 pounds in six weeks, I will guarantee it.
Oprah: I’m gonna do that. OK. That is so good! Whoo! That is great.

Nutrition advocacy group Center for Science in the Public Interest sued Coca-Cola on Thursday for what it calls “deceptive and unsubstantiated claims.”
To be more specific, the accusations build around Coca-Cola’s line of VitaminWater. The consumer group released a statement on Thursday saying that Coca-Cola “markets VitaminWater as a healthful alternative to soda by labeling its several flavors with such health buzz words as ‘defense,’ ‘rescue,’ ‘energy’ and ‘endurance.’” Moreover, the company says its drinks also reduce the risk of chronic disease, reduce the risk of eye disease, promote healthy joints and support optimal immune function.
David Schardt, a senior nutritionist for the nonprofit group, called “nonsense” the company’s claims that one can improve immunity just by drinking one of their VitaminWater drinks.
CSPI nutritionists go even further saying that one such drink contains 33 grams of sugar, which can increase someone’s chances of becoming obese, developing diabetes and other health problems than “the vitamins in the drinks do to perform the advertised benefits listed on the bottle.”
CSPI leader Steve Gardner said it’s shocking that a company like Coca-Cola “feels the need to market a soft drink as a vitamin pill to hide the fact it is really sugar water.” read more by following the link below.
