It you're trying to lose a few pounds but nothing's working... you may want to try coffee.
Drinking eight-ounces of coffee can rev your metabolism by as much as 4% over two and a half hours. For reference, a tall Starbucks coffee is 12-ounces according to registered dietitian nutritionist Karen Ansel.
There are two things that help coffee burn calories: caffeine and the antioxidant chlorogenic acid, which helps break down fat and sugar. But to get the metabolism boosting-effect, you can’t just down a Venti coffee at 8 a.m. and expect to see results. Because the body starts breaking down caffeine after an hour and a half, you need to sip smaller cups, up to four times a day.
You can burn an extra 100 calories a day which can add up to a loss of 10 pounds within a year.
