Loss of Appetite with Green Tea

by Dora Trevino
(Olso, Norway)

Hello, since I have started drinking green tea, I have noticed a significant decrease in my loss of appetite. Does green tea have this effect?

Also, I have noticed a light, minor skin rash on my stomach area. Can this be some kind of allergy or sensitivity?


Dora, studies conducted to date have not found any evidence that drinking green tea can cause a loss in appetite.

A 2000 study conducted by University of Chicago found that rats consumed less food only when they were injected with green tea extract, but not when they drank green tea.

Therefore, for green tea to act as appetite suppressant, you would have to drink A LOT of green tea constantly.

Tea sensitivity and allergy is a potential problems for quite a few tea drinker. Check the link below for further information:

Hope this helps.

loss of appetite?
by: Ian

Dora said she has experienced a 'decrease' in her loss of appetite, but the title just says loss of appetite. I can't decide whether or not it was just a typographical error because in my own experience my appetite increases significantly and very quickly after drinking almost any tea without milk or sugar.

Sometimes after I have just eaten, maybe 10 minutes or so afterwards when I have a green tea for example I feel as if I haven't eaten much at all, if anything! This has a resulting affect on the timing of my tea drinking so as not to overly interrupt my digestion.

Good spot
by: Julian

Good spot. To revise my reply, yes, that is entirely normal. I would think green tea is associated with an increase in appetite rather than the other way round.

There are several possible explanations - all to do with the fact that green tea is good for losing weight:

- Green tea increases metabolism and helps burn more calories.

- Green tea blocks absorption of nutrients, especially when taken around meal time.

- Green Tea burns fat.

With physical activities one develops more muscles, and together with the fat burning, it means one resting metabolism is higher i.e. the long term effect of takinig green tea is greater food intake and more active lifestyle.

Timing of Green Tea
by: Anonymous

My former comment did not have a typo. I have seen a decrease in appetite. Not much, but enough. Perhaps, it has to do with the caffeine, because when I drink coffee, I also have a decrease in appetite.

What is the best time to drink green tea, if one should not drink it with meals?

re: timings
by: Ian

Sorry for the misunderstanding, I just understood a decrease in a loss to result in a positive effect: increase in appetite.

As for timings, I try to make a point of drinking tea at two times during the day: the morning to wake me up and settle my stomach either before or after breakfast (ideally beforehand), and at any other time I am thirsty. I don't like to drink whilst I'm eating anyway, be it tea, coffee or water, as it dilutes digestive acids and results in indigestion. So if I know there's a meal coming up I might hydrate myself well beforehand so I can enjoy the meal. Afternoon is traditionally a nice time for tea and there are few when I don't have a cup or five then.

Hope that helps.
