Is Half-and-Half Keto?

Because it is so high in carbs, half-and-half is not keto-friendly. Unless you monitor your portion sizes very carefully, it is best to avoid half-and-half altogether. This dairy product will also break your fast.

While you replace half of the heavy cream with milk, the fat from the cream is replaced by the sugars in the milk. This can put your body out of ketosis.

High Amount of Net Carbs

If you are following a keto diet, it is best to avoid half-and-half as it is very high in net carbs (4.3g of net carbs in 100g). While it is okay to consume foods high in fat, it isn’t advised with half-and-half because of the high level of carbohydrates.
Keeping your net carb consumption between 20–30g daily is important to stay in ketosis.

Not an Ideal Source of Fat

Because your body will only be able to use fats as energy if you restrict your net carbs, it is important to get your fats from high-fat foods, which are also low in net carbohydrates.
