Keto fats, sauces and oils – the good, the bad and the ugly
What fats, oils, sauces and dips can you add to your food and stay keto? What’s best for your health?
The numbers are the average amount of net carbs per 100 grams (3.5 ounces).2 To the left, in the green zone, are choices with less than 5 grams of carbs. Choices in the red zone, to the right, have a lot more carbs and likely need to be avoided even in small amounts to stay in ketosis. See our best tips for getting into ketosis
In a keto contest between mustard and ketchup, who wins? Mustard, hands down. Ketchup is full of sugar; mustard often has little or (occasionally) none.
But again, read labels carefully as some mustard brands do sneak in sweeteners. For example, traditional Dijon mustard has zero carbs while some “honey” mustard brands may have 10 grams or more.
Feasting on tasty baby back ribs or a seared steak fresh off a hot grill is one of the great pleasures for many on the keto diet. However, beware of store-bought barbecue sauces, which are often high in sugar. Eat them with full knowledge of their carb hit, or try instead a savory, sugar-free rub or just season with salt, pepper, and powdered or minced garlic.
Most of us start out understandably fat phobic after 40 years of being encouraged to eat low fat.

A word about oils
What about vegetable, nut and seed oils? This is a bit more complicated. Natural oils that have been around for thousands of years are generally safe and should be embraced on a keto diet.
Feel free to use pure olive oil, ghee, avocado oil, almond oil, peanut oil, sesame oil, fish oil — anything for which it is easy to extract the oil with simple pressing, grinding, churning or low heat separating.
We do recommend minimizing the use of industrial seed or vegetable oils created within the past 60 years, such as corn oil, soy oil, safflower oil, sunflower oil, and cottonseed oil. These oils are created by chemical extraction and high heat industrial processes.6 Since it’s not clear what kind of effects this might have on health, we feel that sticking with traditional, less processed fats makes sense.

Studies have shown that people who eat high-fat keto meals typically feel fuller and less hungry:
Net carbs = digestible carbs, i.e. total carbs minus fiber. ↩
In a review of more than 40,000 products at a large Canadian grocery retailer, 66% were found to contain one or more added sugar:

Are you concerned about saturated fat? In all likelihood, you may not need to be. Although still somewhat controversial, several recent systematic reviews of randomized trials have failed to show a connection between eating saturated fat and increased heart disease risk:
In a recent study lasting two years, nearly 200 people followed a keto diet that allowed them to eat as much fat as they needed to feel satisfied:
