FAQ
How many calories are in bacon?
About 43 kcal in one cooked medium slice. A 3-slice portion is roughly 130 kcal, and thick-cut slices run closer to 60 kcal each.
How many calories are in one slice of bacon?
A typical pan-fried slice is around 43 kcal — about 31 kcal for a thin diner strip and up to 62 kcal for a thick-cut slice.
Why is bacon so high in calories for its size?
Bacon is mostly fat, and fat carries more than twice the calories of protein or carbs gram for gram, so small slices add up quickly.
