Can I consume eggnog on keto?

Not really, due to high carb content. Unless you make it yourself with keto-friendly ingredients.

How to make:
Keto-Friendly Egg Nog Ingredients:
2 cups heavy cream (grass-fed) 1 cup coconut milk
4 large eggs (pasture-raised)
3 Tbsp xylitol (or swerve)
1 tsp vanilla
2 tsp cinnamon
1 tsp allspice
Instructions: Blend it up!
