How Many Calories Are in a Slice of Bacon?

Bacon, which is cured pork belly, is widely used in breakfast dishes and as a topping for sandwiches and salads. While a single slice appears small, its calorie count is surprisingly variable and depends almost entirely on how it is prepared. Understanding these variables is key to assessing its place in any diet.

Calorie Counts Based on Preparation Method

The cooking method is the most significant factor influencing a slice of bacon’s final calorie count, as it dictates how much fat is rendered out. Raw bacon contains a high amount of fat; a single ounce (roughly one large slice) can contain over 110 calories, but this form is rarely consumed.

When heat is applied, the fat melts and separates from the meat, a process known as rendering. The majority of the calorie reduction in cooked bacon comes from this rendered fat that is left in the pan and not consumed. A cooked slice of standard pork bacon that is left pliable and chewy retains more fat, typically containing around 50 calories per slice.

Cooking bacon until it is crispy allows more of the fat to drip away, leading to a lower final calorie count. A thoroughly drained, crispy slice of bacon generally falls into a range of 30 to 45 calories. The difference between a chewy slice and a crispy slice is a function of the remaining fat content.

Comparing Different Types of Bacon

While preparation is important, the source cut of meat also influences the final calorie count. Traditional pork bacon, which comes from the fatty pork belly, provides approximately 40 to 43 calories for a medium, pan-fried slice. This standard version is the benchmark against which other types are compared.

A leaner option is center-cut bacon, sourced from the more uniform, meatier portion of the pork belly, resulting in less overall fat marbling. Center-cut varieties have less fat before cooking, translating to a lower calorie count. A serving of two slices of center-cut bacon can be around 10 calories less than a comparable serving of regular bacon.

Turkey bacon, made from ground and seasoned dark and light turkey meat, is another alternative. Because the source meat is naturally leaner than pork belly, a thin slice of cooked turkey bacon typically contains fewer calories, often around 30 to 35 calories per slice. Turkey bacon is a manufactured product, and its final nutritional value can vary significantly based on the binders and flavorings used during processing.

Beyond Calories: The Full Nutritional Snapshot

Bacon is a source of complete protein, an important macronutrient for muscle maintenance and satiety. A single cooked slice can provide approximately 3.6 grams of protein.

The fat content in bacon is composed of both saturated and unsaturated fats, with saturated fat being the primary concern for heart health. Bacon also contains several micronutrients, including B vitamins (B1, B2, B3, B5, B6, and B12), which play a role in energy metabolism. Minerals such as selenium and phosphorus are also present.

The sodium content is elevated due to the curing process. A single slice of bacon can contain 160 to 185 milligrams of sodium, which quickly accumulates if multiple slices are consumed. Individuals monitoring their blood pressure should be aware that a few slices can contribute a substantial portion toward the daily recommended limit for sodium intake.
