I wouldn't believe all the health benefits of green tea. That being said I'm a real green tea nut. It's a fairly good source of anti-oxidants and contains a small amount of caffeine. The amount of caffeine depends on the type of tea and the steeping time. Green teas should be brewed at a lower temperature, 180F, for 3 minutes.

There are teas such as Genmai Cha, that also contain rice and popcorn that cutdown on the caffeine and may introduce a small amount of carbs (very small).

A great site to buy and learn about tea is www.adagio.com.

I have made the switch to green tea and have not found it to increase my appetite at all. I had reached a weight plateau, stuck at 172-175. I read here about green tea and decided to drop the coffee for three servings of tea day. In just a couple of weeks I am down to 167. Sometimes it takes just a little change for your body to move off its "set" weight. At least for me it seems my body finds a certain weight range and then is stays within that range. Then no matter how much I eat or don't eat, workout or rest, my weight stays in that pretty small range. I then have to find out what I can add or take away from what I am doing to get things moving down again. For me it was green tea. I would recommend the tea if your looking for that little sumin-sumin to get you over the hump.
