It does have caffeine so it would probably depend on your sensitivity.

Green tea is not a magic potion for weight loss.

Personally I do not like the term “dieting” – as weight loss is about a life style change. Exercise regularly and logging your food intake/calories will lead to your goal.

I use Fit Bit to monitor my activity and calories, it’s been a great way to measure and achieve my goals. This isn’t a plug for Fit Bit, I am not a salesperson for them, but rather refer to them as an example of something that worked for me.

Green tea might curb appetite as they claim but it shouldn’t be the highlight of your plan… good luck

It looks like the side effects are relatively minor, heartburn, gastritis, etc, but so too are the benefits. It helps a little but not much with weight loss and cholesterol. It’s the lifestyle and diet that matters more.

There are virtually no negative side-effects to drinking green tea, even if you drink a gallon of it per day. The only thing that it can do in high amounts is inhibit your body’s ability to absorb iron and folic acid. For most people, the risk here is negligible. Only women who are pregnant or trying to get pregnant are advised to hold back, and even then the recommendation is to limit oneself to one or two cups per day. Moreover, the problem can be completely negated with a vitamin supplement.

That said, the optimal amount seems to be around seven cups, and there is no real benefit to drinking more than 10 cups of green tea in a day. It’s just the law of diminishing returns: eventually, your system just won’t process the catechins as efficiently (note: the mechanism by which green tea provides health benefits is unclear at present; I cite the catechins because they are what most researchers suspect to be responsible). So if you can manage seven cups without intestinal discomfort, there’s no reason to go for more.

Finally, I agree with the answers above that green tea is ultimately nothing more than a supplement. It can help you lose weight, but it won’t lose weight for you. So while seven cups may be optimal for health benefits (including those that go beyond weight loss), this does not mean that you should feel pressured to drink that much. Other factors—such as overall diet and exercise—are more important than whether you had three cups or 30 cups of green tea.

P.S. My answer has been informed in part by this study.

^Actually it does stain and weaken the enamel on the teeth. Or that is what my dentist told me being an avid tea drinker. As to too much well I would say when your body tells you it doesn’t want tea. I used to very disconnected from my body. And the term craving meant nothing to me. But I find that when I crave something it tastes infinitely better to me and satiate it I am more blase about the taste while still enjoying it to a degree. When I have had too much of something I don’t like the tastes, if I force myself to drink it. My brain usually rejects the item before I get to the point where it doesn’t taste appealing.

@Unbroken Regarding the weakening of enamel, did your dentist specifically mention green tea? Because these two studies suggest quite the opposite.

@SavoirFaire No I suppose she didn’t, I just must have mentally added that information because that is what I drink the most of, though herbal, black, rooibos,white, oolong, chai, fruit infusons and matcha all get their time, though not so much.. thank you for the info.
