Is Kefir Keto?
Kefir is not keto-friendly because it is high in carbs. It may kick you out of ketosis even with a small serving size.
Too Much Carbs!
Kefir should be avoided on keto because it is very high in net carbs (11.45g of net carbs per 240g serving).
It is important to limit your net carb consumption to 20g - 30g per day to stay in ketosis. You can calculate your ideal daily net carb allowance by using this keto macros calculator.
As an alternative, you may look for other dairy products that are low in net carbs.
Low in Fats
Kefir is both high in carbs and low in fats, which are the exact opposite of the macros required on a keto diet.
The ideal macronutrient ratio for keto is 70% fat, 20-25% protein, and 5-10% carbs. This means the majority of your foods should be both low in carbs and high in fats.
Avocado, salmon, and ghee are great examples of foods that are both low in carbs and high in fat.
Minimally Processed But High in Carbs
Kefir is minimally processed but not a good fit for keto because it is high in carbs.
It is important to check both macros and ingredients of your foods to achieve a healthy weight loss on keto.
Here are the common ingredients to be checked for keto - sweeteners, oils, and food additives.
