Bacon calories and nutrition facts
100 grams of bacon contains 541 calories, with 37 g of protein, 1.4 g of carbohydrate and 41.8 g of fat. Most of its calories come from fat.
Bacon's numbers depend almost entirely on how crisp you cook it — rendered fat left in the pan is energy that never reaches the plate. A single grilled rasher is a modest 30-40 calories; the damage usually comes from the count, not the rasher. Salt is the quieter number worth noticing here.
