Is Sour Cream Keto? The Lowdown On Dairy Products Allowed On The Keto Diet

The crux of the ketogenic diet is avoiding high-carb foods and instead opting for high-fat options. Such a nutrition plan drives the body into a fat burning state and kick-starts weight loss. Furthermore, eating low-carb foods can alleviate chronic disease symptoms (8, 10). Sour cream is a fermented dairy product. Generally, the nutrition facts label says that sour cream is high in fat (around 80%) and low in carbohydrates (around 3%). Therefore, it is a keto-friendly product (4). If you are not allergic to lactose, sour cream can be a great addition to your every day keto menu.

How to buy the best keto-friendly sour cream?

Conforming to the daunting keto-diet guidelines is not enough. You have to be extra vigilant when cruising around a grocery store in search of a keto-approved product.Tossing just about anything in your shopping cart won’t cut it.Dairy seems to throw keto devotees off their balance the most, especially when it comes to picking the right sour cream. That’s why we’ve rounded up a list of tips you can use, when perusing the sour cream shelves, that might just make your keto journey a little less bumpy. 

How to buy the best keto-friendly sour cream?

  • Avoid artificial sweeteners. They ramp up your carb intake which in turn hampers the process of ketosis. 
  • Find non-GMO and no preservatives tags on packaging. Studies on GMO products are controversial. Scientists and consumers debate regarding possible health and environmental risks from cultivation and consumption of genetically modified food (5).
  • Opt for high-quality grass-fed organic sour cream
  • Look for high-fat but not margarine produced. Trans fats shoot up “bad” cholesterol levels.
  • Keep a sharp eye on the nutrition label. You should always pick out sour creams with the lowest net-carb content. 
  • Don’t let ads sweet-talk you into buying “low fat”, “low calorie” sour creams. Brands tend to bend the rules by adding sugars, artificial sweeteners and chemicals to make up for the taste, reduce fat content and  curtail the amount of calories.

Alternative recipe of sour cream on the keto diet

Another way to make sure adding a spoonful of sour cream to your salad won’t kick you out of ketosis is by making it yourself. This recipe consists of measly 2 ingredients, so anyone would be able to do a stand-up job whipping up a batch of sour cream at home instead of buying it: 

  • Heavy cream
  • Starter culture

The proportion depends on the type and thickness of products. Use approximately 1 liter of heavy cream and 1 packet of starter culture.


  1. Heat heavy cream in a saucepan to room temperature or a bit warmer.
  2. Combine warm heavy cream and starter culture.
  3. Stir it and transfer to a jar.
  4. Leave the jar for 16-18 hours at room temperature to give your “concoction” time to ferment.
  5. When your sour cream is ready, pop it in the fridge.

Making sour cream at home will never have you wondering about any keto-derailing ingredients or health-jeopardizing additives. Moreover, you can store it for 2 weeks and add it to any recipe you have in mind. Enjoy your sour cream-filled keto journey!

Mistakes to avoid while consuming sour cream on the keto diet

Sour cream is a great keto-friendly product that is bursting with flavor and nutrients. However, it is important to remember that serving portions should be calculated accurately in order not to overshoot your carbohydrate allotment. 

Eating even fermented dairy can be unhealthy for people allergic or sensitive to lactose. Furthermore, sour cream includes natural sugar because lactose breaks down into glucose and galactose. Therefore, people with diabetes and other conditions that might become exacerbated by a spike in blood sugar levels  should consult with a doctor.
