Green tea is a type of tea that is made from Camellia sinensis leaves that have not undergone the same withering and oxidation process used to make oolong and black tea. Green tea originated in China, but its production has spread to many countries in Asia.
Several varieties of green tea exist, which differ substantially because of the variety of C. sinensis used, growing conditions, horticultural methods, production processing, and time of harvest.
Many people advocate the drinking of green tea as a fat burner. Whilst this is true, it has very minute benefits to aid fat loss and help to oxidise fat. It will also help slightly with blood flow and insulin sensitivity.
In other words, it will help, but only slightly and ONLY if taken as part of a calorie deficit. You can still drink regular tea though if you prefer.
I personally enjoy green tea more than regular tea, especially the Twinings Pineapple and Grapefruit bags.
