Dropping weight as simple as sipping coffee all day.
Research found drinking eight ounces of coffee can rev your metabolism by as much as four percent over two and a half hours.
So if you drink enough coffee each day you can burn an extra 100 calories, which can make you lose ten pounds over the course of a year.
This is because coffee contains caffeine and the antioxidant chlorogenic acid, which helps metabolize sugar and fat.
To really reap the benefit, drink small cups of coffee up to four times a day.
