How the foodfest sits with you depends on your genes, your body composition, your system’s response to certain hormones and your regular eating and exercise habits, said McDaniel.

For instance, regular exercisers who work out 12 or fewer hours before a big meal fare better than others. Their bodies tend to have a more sensitive insulin response, allowing them to more efficiently process the excess carbs, and a more robust circulatory system to weather the influx of fat circulating in blood. What can you do after the deed is done? Don’t lie down, or many of these problems may be exacerbated.
