The USDA National Nutrient Database puts fried chicken wings without sauce at roughly 103 calories each. Add on the traditional fat-laden Buffalo sauce, and the calories quickly add up.
The Buffalo wings at the Wings to Go chain are roughly 117 calories each, while Hooter's wings weigh in at more than 170 calories each.
Buffalo chicken wings have a triple whammy when it comes to calories: They have the chicken skin still on; they are deep fried; and they are tossed in a sauce that is part hot sauce and part butter. The butter cuts the heat of the sauce, so milder Buffalo sauces usually contain more calories than those with a higher heat ratio.
