pizza: It was a large pepperoni pan crust pizza from pizza hut. All together I know that a slice of that would have 380 calories according to the nutrition facts online. However when I took the cheese off, i noticed that that it was really thick, so im sure alot of the calories came from that. About how many calories are in a slice of the pizza without the cheese?|||Probably about 250.. just a guess. Have the piece of pizza if it's early in the day where you are. Just drink lots of water and burn some calories off exercising soon or later in the day. Eat well for the next few days and you'll be fine.|||Calories is a major topic when it comes to weight loss.
