GREEN BAY, Wis. (WBAY) -- Dietitians say on average, adults should take in anywhere from 1,500 to 2,000 calories per day.
But on Christmas Day, your calorie intake could almost quadruple.
Between breakfast, alcohol, sweets, dinner, and snacks -- studies calculate the average person could take in a whopping 7,000 calories on Christmas Day without realizing it.
One dietitian said during the holidays people are often bombarded with sweet treats and alcoholic beverages, both of which are high in fat and sugar.
Health experts recommend having a snack that's high in fiber and protein before going to family gatherings.
Another trick to curb calorie intake is to fill half your plate with fruits and vegetables because it's low in calories-- then fill the other half with foods you want to indulge in.
"Weight gain is gonna be an obvious effect of overeating- if you're eating 7,000 calories in one day you're likely gonna feel like you're having brain fog, like you're gonna be pretty groggy, you're just not really gonna be feeling like your best self," said dietitian Carrie Taicher.
Dietitians recommend waiting 15 to 20 minutes before getting a second plate of food to also help curb your calorie intake.
