don't know if it works to speed up the metabo but I live in hope....
Well, pleased to report that it does speed up the metabolism, even more than caffeine..
If you have 5 cups a day, every day for a year, the change in the metabolic rate could equal as much as 2.15-2.50 ounces a week :clap: But, the results are inconclusive and might not be that much. And the tests didn't even check for long term use anyway.
Of course, you can knock off some of that 2.15oz if you are swapping your coffee for green tea, as coffee speeds the metabolism to a certain extent anyway.
If you like green tea, drink it. It has many other health benefits, but don't just drink it for the metabolic burn effect, because it's so tiny.
