The crux of the ketogenic diet is to reduce the carbohydrate intake and increase the fat intake instead. Such a nutrition plan drives the body into a fat burning state and kick-starts weight loss. Furthermore, eating low-carb foods could potentially alleviate chronic disease symptoms (8, 10). Sour cream is a fermented dairy product. Generally, the nutrition facts label says that 20% M.F. sour cream is high in fat (around 86% of total calories) and low in carbohydrates (around 9% of total calories). Therefore, it is a keto-friendly product (4). If you aren’t sensitive to lactose, sour cream can be a great addition to your every day keto menu.

  • Avoid artificial sweeteners. They ramp up your carbohydrate intake which in turn hampers the process of creating a ketosis state. 
  • Favor 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. Food items like hydrogenated margarine are high in trans and saturated fats shoot up “bad” cholesterol levels.
  • Keep a sharp eye on the nutrition label. You should always pick out sour creams with the lowest carbohydrate 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 and texture loss, 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 creating a ketosis state 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 (35% M.F.)
  • Starter culture (lactic acid bacteria)

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. Full fat sour cream is made from heavy cream and therefore contains more mostly fat rather than carbohydrate. On the other hand, light or nonfat sour cream has a more even ratio of carbohydrate to fat, which isn’t ideal for people adopting the ketogenic diet. As a golden standard, you should always opt for a full fat sour cream (20% M.F. and higher).

Eating even fermented dairy can be unhealthy for people intolerant 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 or a dietitian prior to starting a ketogenic diet.
