Is your caffeine fix making you fat?

Knocking back five cups of coffee per day may lead to weight gain and increase the risk of diabetes, researchers have warned. 
While previous studies have shown coffee in moderation could help weight loss and actually reduce the risk of type 2 diabetes, these recent findings suggest that too much coffee could prevent weight loss. Australian researchers found that over- consumption of certain polyphenols found in coffee called chlorogenic acid (CGA) could prevent fat loss and lead to insulin resistance.
The study, which was published in the Journal of Agricultural and Food Chemistrytested CGA's effects on obese mice, which were given different doses of the compound. The mice that were given doses equivalent to five or six cups of coffee per day showed retention of fat within cells.
