About Bacon

Bacon has a complicated nutritional reputation. On one hand, it is undeniably high in saturated fat and sodium. On the other hand, it is a keto staple, provides quality protein, and is one of the most flavor-dense foods on earth. A single slice of pan-cooked bacon contains 43 calories, 3 grams of protein, and 3.3 grams of fat — actually quite modest for how satisfying it is.

The 3-slice serving that comes with most breakfasts contains about 129 calories and 9 grams of protein. Bacon is high in sodium (about 137mg per slice) and contains nitrates used in curing, so moderation is wise for those with high blood pressure or concerns about processed meat consumption.

Despite its reputation, bacon fits into many diets when consumed mindfully. It is a staple of ketogenic, low-carb, paleo, and carnivore approaches due to its macronutrient profile (0g carbs, high fat, moderate protein). The fat in bacon is primarily monounsaturated, similar to olive oil, which is often overlooked.

Turkey bacon has significantly fewer calories (about 25 per slice) and less fat but more sodium per serving. Canadian bacon (back bacon) is leaner and higher in protein. BasedHealth tracks all three variants accurately.
