London: Bored women are `auto-eating` their way into a bigger dress size in weeks by eating as much calories as a Big Mac in a single day, found a study.
The study of 5,000 adults, carried out by slimming aid firm APPEsat, revealed that a quarter of the food eaten each day is consumed by people who are not even hungry.
Typically, women are over-eating by 520 calories a day, piling on 7lbs - equal to a dress size - in as many weeks.
A Big Mac contains 492 calories.
Men also eat an extra 650 calories a day.
And researchers have found that boredom is the main reason for auto-eating.
Women are more prone than men, especially if they are also upset.
"Controlling what you eat is not simply a matter of willpower, it is about being aware of the desire to eat and understanding your your relationship with food," a news daily quoted nutritionist Mary Strugar, who coined the auto-eating term.
