A few slices can add up fast. When University of Bath researchers instructed young men to eat Domino’s pizza until “comfortably full,” the participants consumed an average of nearly 1,600 calories each.
But that’s not all: When the same group was told to indulge until they “couldn’t eat another bite,” they nearly doubled that amount—downing 3,100 calories.
The upshot: It’s way easier to overeat ultra-processed foods like pizza than most people think.
That’s because these foods are loaded with calories, taste delicious, and aren’t particularly filling.
So if you’re going simply by how you feel—and not aware of calories per portion—you may eat way more than you wanted to.
