yes! herbal tea – (green tea, white tea, oolong/red tea) all contains polyphenols which have a range of benefits. you can get green tea which has been oxidised, black tea, completely oxidised, oolong/red tea which is semi-oxidised or white tea, unoxidised. the difference is that oxidation causes stronger concentrations of caffiene which stimulate the metabolism and therefore you lose weight.
however, unoxidised or less oxidised tea, if you drink it before you eat, causes your insulin levels to rise which burns fat. also, drinking any sort of chinese/japanese herbal tea 15 minutes before eating increases energy expenditure 10%. if you drink tea immediately after eating, you burn an extra 10% of fats. also, note that green tea has only 4 calories per cup!
Also, it is believed that the polyphenols in tea seem to aid in the digestion of fat, truly making it a Chinese diet tea.
also, Japanese researchers claim if you drink five cups of green tea a day, you’ll burn 70 to 80 extra calories. Dr. Nicholas Perricone, an anti-aging specialist, appeared on the Oprah Winfrey show and told Oprah’s viewers they can lose 10 lbs. in 6 weeks drinking green tea instead of coffee
not to mention herbal tea has a wide range of health benefits – i.e women drinking 4-6 cups a day have 46% less chance of getting ovarian cancer, it’s an anti-aging substance – notice how women in asia have beautiful skin and look years younger?
green tea burns up calories and stimulates your metabolism, provided of course, you don’t add any sugar or milk or whatever. if you want green tea to work, you need to drink 4-6 cups a day and you should see results not only in your weight, but your overall body. green tea is a natural relaxer and it also helps clear your skin!
