"We accumulate stored fat very fast," says Dr Pablo Enriori, from Monash University's Neurophysiology research group. "In 15 minutes you're going to get a lot of insulin in circulation. This is induced to accumulate fat in tissue as well as used in the form of glucose for muscles."

"Six hours is when we start to store that body fat but if by lunch you've overeaten and starting to store fat you've still got half a day to fix it, by either going to the gym and burning it off or reducing the amount of food you're eating later in the day," says exercise physiologist and dietitian Matt O'Neil from Metabolic Jumpstart.

"By the next day you'll have more body fat unless you have burnt it off the same day."
