Yes, you can eat coleslaw on a keto diet, but it depends on the ingredients used in the coleslaw. Traditional coleslaw recipes often contain high-carb ingredients like sugar and mayonnaise, which are not keto-friendly. However, you can make a keto-friendly coleslaw by using low-carb ingredients such as cabbage, mayonnaise made with avocado oil or olive oil, and a sugar substitute. It's important to check the specific recipe or ask about the ingredients before consuming coleslaw on a keto diet.
