Americans consume a large amount of calories during the Super Bowl. Households purchase food items whose single servings add up to over 6,000 calories during the week of Super Bowl. This is the largest amount of calories for any week throughout the year, even more than during Thanksgiving.

The week before the Super Bowl is the second-unhealthiest week, when people buy closer to 5,500 calories per serving.

A new study tracked grocery spending habits of over 200 households in New York over the course of seven months. The idea was to know whether people were any good at keeping New Year's resolutions. However, the findings also showed that Americans consumes a huge amount of food during the Super Bowl.

'Super Bowl party foods' include countless heart-unhealthy recipes items such as pigs in a blanket, cheesy dip, greasy burgers, football-shaped cakes and so on.

The reason behind overeating on Super Bowl Sunday has been explained by Dr. Sharad Wagle, chief of psychiatry at Holy Name Medical Center in Teaneck. According to him, "Some people are so glued to the TV in anticipation, so eager, that it causes them to nibble on whatever's there. If the game is going their way and their team is winning, people will stuff themselves to celebrate".

Anxiety, elation and boredom can also cause overeating. Group mentality may also be a factor. People who stuff themselves with the huge calories food also encourage others to join in.

According to Melissa Buczek Kelly, a registered dietitian and nutritionist based in Wayne, after one consumes those unhealthy items, he should just forget about it. Buczek Kelly said that it should be considered as a snapshot and it is one out of 21 meals in a week and not the end of the world.
