I am on a diet and wanted to know whether Diet green tea will speed up my metabolism?

Seth's right, actually. Green tea speeds up metabolism from caffeine, along with polyphenols, which apparently burn fat. It's not as much caffeine as coffee or black tea, but it's still in there.

And this doesn't really answer your question, but what in the world is "Diet" green tea? When you make green tea from tea leaves, you get virtually no calories in the first place. So if they're calling it "diet" I don't know what they're taking out. Unless they sell two pre-brewed versions and load one up on sugar and chemical flavoring... I wouldn't trust any bottled green tea for any of the claimed health benefits.

Green tea diet is only part of the solution! If order to properly speed up your metabolism you need to eat healthy and at least exercise a little bit each day.

After you start to eat right, drinking green tea help you dramatically start to shed the pounds and increase your metabolism.

Good luck and use my reference below for more interesting information about green tea diets.

Primarily, it's the caffeine that increases your metabolism. As long as the caffeine is the same, you should be fine. However, tea only contains about 4-8 calories (no sugar), so I don't see the point of Diet.

If by "speed up my metabolism" you mean "make me use the toilet a lot" then yes. Oh, and @ Seth, most Green Tea is caffeine free.

yes..i drink 3 glasses of plain green tea daily...its the most affordable diuretic on the planet,so you have to drink equal amounts of water in betweens..with a strict regime of cardio and yoga/pilates combined with a portion controlled diet,im amazed by the results im getting weekly...

I don't know about green tea, but HCG works really well...
