It has long been thought to be the enemy of the waistline.
But fat can actually protect people against obesity and developing diabetes, scientists have today claimed.
Before reaching for a cream cake though, take note - it is 'good' brown fat that is beneficial to the body, not white fat, which is amassed from gorging on too many calories.
Adults have a small amount of healthy brown fat, usually found in the front and back of the neck and upper back, which burns calories in order to generate heat.
In contrast, white fat is troublesome.
It is the result of eating too many calories and is stored around the stomach, thighs and forms the dreaded love handle.
