I try to exercise everyday in order to increase my metabolism, and I recently read that drinking green tea may be beneficial for my metabolism too. The problem is that I try to consume as little caffeine as possible, as it gives me acne. I don’t have access to caffeine free green tea for the moment (because I am abroad and I couldnt find it nor get information). Still, I wonder if 1 cup per day would be enough, or if the more I drink, the best. ?
If you can’t have caffeine, then dont’ drink tea for the metabolism boost. The University of Geneva study linked below (wiki) states that the boost comes in large part from caffeine. (A lot of diet pills are just caffeine pills.)
And while you could get decaf for the other health benefits, you can’t be sure that the chemicals used in decaffeination don’t strip out what causes the other health benefits.
That said, if you do continue to drink it, know that many of the studies are done in east Asia on people who were already drinking green tea. And custom in China & Japan is to drink tea *as what they drink*, not just one cup a day. It’s not a magic elixir, but it is a lifestyle.
