Those butter-based sauces would replace the pat of butter mentioned in post #5. Dr Westman and Eenfeldt do want you to use enough fats to make vegetables taste good...but not over- indulge. By no added fats, I meant what has become a problem with "internet keto" ....the butter in coffee, sweetened fat bombs, coconut oil smoothies. This is a "diet" that allows you to eat juicy, fatty burgers, whole eggs with a dab of mayo, so enjoy the real food. The 3 cups of veggies taste better with some fat...roast or stir fry a selection of veggies in some olive oil, add 2T of a butter sauce to asparagus, but don’t whip a 1/2 cup of cream for a dessert.
