According to research from the Calorie Control Council, the average American may consume more than 4,500 calories and a whopping 229 grams of fat during a typical holiday gathering from snacking and eating a traditional Thanksgiving dinner with turkey and all the trimmings.
The 141 pounds of sweeteners (including 42 pounds of corn syrup a year), and 85 pounds of fats (think: butter) and oil we ate.

It's hovering around 2,700 (of course, these are just averages).
