How many carbs are in bacon?
Cooked bacon has almost no carbohydrate. One slice (8g) has about 0.1g of carbs, and 3 slices have about 0.3g.
Carbs by portion
| Portion | Total carbs | Fiber | Net carbs |
|---|---|---|---|
| 3 slices cooked (24g) | 0.3g | 0.0g | 0.3g |
| 1 slice cooked (8g) | 0.1g | 0.0g | 0.1g |
| 1 oz (85g) | 1.1g | 0.0g | 1.1g |
| 100 grams | 1.4g | 0.0g | 1.4g |
Net carbs
Three slices of cooked bacon contain about 0.3g of net carbs. There is no meaningful fiber, so net carbs and total carbs are the same. At this level, bacon adds essentially nothing to your daily carb total. See the net carbs guide for context on when the distinction matters.
For diabetes
Bacon has almost no carbohydrate, so it does not directly raise blood glucose. Three cooked slices carry about 0.3g of carbs, which is not worth dosing for. What bacon does carry is saturated fat: about 3.5g per slice. Long-term, high saturated fat intake is associated with insulin resistance in people with type 2 diabetes. For people with type 1, the fat can slow gastric emptying when bacon is part of a larger mixed meal, shifting the glucose response of those other foods. See the diabetes carb-counting guide.
Keto and low carb
Bacon is one of the most keto-compatible foods you can eat. Three cooked slices have about 0.3g of net carbs, which is negligible against a 20 to 30g daily keto budget. It is high in fat and protein with virtually no carbohydrate, which fits the keto macro profile well. The main caveat is sodium: many cured bacons are high in salt, and some add sugar to the cure.
Good to know
Bacon is cured pork, and the cure matters for carb content. Plain baked or pan-fried bacon has about 1.4g of carbs per 100g. Maple-cured, brown-sugar, or honey-glazed bacons can run 3 to 6g per 100g because sugar is rubbed into the meat before smoking. Turkey bacon is lower in fat but often comparable or higher in carbs due to added fillers and sugar. Canadian bacon (back bacon) is a different cut, leaner, and also low in carbs but worth checking the label.
