Yes, bacon is low carb. A typical slice of cooked pork bacon contains less than 0.5 grams of carbohydrates, and even thicker or sugar-cured varieties rarely exceed 1 gram of carbs per slice. That makes bacon one of the most keto-friendly proteins available, which is why it shows up on nearly every low-carb meal plan.
But not all bacon is created equal. The curing process, added sugars, and the type of bacon you choose can shift the carb count slightly, and there are other nutritional factors worth knowing about if bacon is a regular part of your diet.
Carbs in a Slice of Bacon
Plain cooked pork bacon has close to zero carbohydrates per slice. Most nutrition labels list it at 0 grams for a standard thin-cut slice. The calories in bacon come almost entirely from fat and protein, not carbs, so it fits comfortably within ketogenic, Atkins, and other carb-restricted eating patterns.
Even if you eat four or five slices at breakfast, you’re still looking at roughly 0 to 2 grams of total carbs for the whole serving. For context, most keto diets set a daily cap of 20 to 50 grams of carbs, so bacon barely registers.
Why Some Bacon Has More Carbs
The small amount of carbohydrate that does appear in bacon comes from the curing process. Most commercial bacon is cured with a mixture of salt, sugar, and nitrates. That sugar soaks into the meat and doesn’t fully cook off. A thick-cut, sugar-cured bacon like Hormel Black Label contains about 1 gram of sugar and 1 gram of total carbs per two-slice serving. It’s not much, but it’s not zero.
If you want to eliminate even that small amount, look for bacon labeled “no sugar added” or “sugar-free.” These varieties exist specifically for low-carb and paleo shoppers. Greenfield Natural Meat Co.’s no-sugar uncured bacon, for example, lists 0 grams of carbohydrate per slice. Brands like Pederson’s and Applegate also make no-sugar options that are widely available. Flavored bacons (maple, brown sugar, honey) will have higher carb counts, sometimes 2 to 3 grams per serving, so check the label if you’re tracking closely.
Turkey Bacon vs. Pork Bacon
Turkey bacon is also low in carbohydrates, typically under 1 gram per slice, similar to pork bacon. The bigger difference between the two is fat content. Turkey bacon has roughly 14 grams of total fat per serving compared to 22 grams for pork bacon, with saturated fat dropping from about 8 grams to 4 grams. If you’re eating low carb primarily for weight loss and want to keep calories in check, turkey bacon saves you some fat calories per slice. From a pure carb-counting perspective, though, the two are essentially interchangeable.
Bacon on a Keto Diet
Bacon is practically a mascot for the keto diet, and its macronutrient profile explains why. High fat, moderate protein, near-zero carbs. That ratio aligns perfectly with the ketogenic approach, where 70 to 80 percent of daily calories come from fat.
Some people worry about the saturated fat in bacon when eating keto. Research published in Nutrition & Metabolism has argued that restricting saturated fat on a low-carb diet is unnecessary, pointing to favorable responses in markers for diabetes and cardiovascular disease even when the diet is rich in saturated fat. Stearic acid, a major saturated fat found in pork, has repeatedly been shown not to raise LDL cholesterol levels. That said, this remains an area of ongoing scientific debate, and the context of your overall diet matters more than any single food.
Sodium Adds Up Quickly
The more practical concern with eating bacon regularly isn’t carbs. It’s sodium. A single cooked slice contains about 178 milligrams of sodium. Eat four slices and you’ve taken in over 700 milligrams before you’ve added anything else to your plate. The general recommendation for daily sodium intake is under 2,300 milligrams, so a generous bacon serving can account for a third of that limit in one sitting.
If you’re on a low-carb diet that also includes cheese, pickles, deli meats, or salted nuts, your total sodium intake can climb fast. Drinking plenty of water and balancing your meals with potassium-rich foods like avocado and leafy greens helps offset this.
Processed Meat and Long-Term Health
Bacon is a processed meat, and that classification carries health considerations beyond its macros. The curing process introduces nitrites, which can form compounds called nitrosamines during high-heat cooking. These are recognized carcinogens that also affect cardiovascular and metabolic function. Research has linked excessive nitrite intake from animal sources to increased cancer risk, particularly thyroid cancer in women.
The American Heart Association’s 2026 dietary guidance is clear on this point: if you eat red meat, avoid processed forms and limit portion size. Their analysis found that replacing processed meats with other protein sources is associated with lower mortality rates. Common examples they flag include bacon, sausage, hot dogs, and deli meats.
None of this means you need to eliminate bacon entirely. It means treating it as an occasional addition rather than a daily staple is a reasonable approach, even if it fits your carb goals perfectly. Uncured varieties that skip the added nitrates are one way to reduce exposure, though “uncured” bacon typically still uses celery powder, which contains naturally occurring nitrates.
Choosing the Best Bacon for Low-Carb Diets
If you’re optimizing for both low carbs and overall quality, here’s what to look for on the label:
- No sugar added: Eliminates the 0.5 to 1 gram of carbs per slice that sugar curing adds.
- Uncured or nitrate-free: Reduces your exposure to added nitrites, though naturally occurring nitrates from celery powder are still present.
- Center-cut: Slightly leaner with the same carb count, trimming some of the excess fat from the belly portion.
- Pasture-raised: Higher cost, but the fat profile tends to include more omega-3 fatty acids compared to conventionally raised pork.
Cooking method matters too. Baking bacon in the oven at 400°F renders more fat and produces a more even cook than pan-frying, which can create more charring. Since nitrosamines form more readily at high temperatures, avoiding burned or heavily charred bacon is a simple way to reduce your exposure.
