In response to both of you, I really don't think that you have "fasted" in a particular period if you are consuming calories at all.

You're certainly restricting calories and I'm sure it's a positive step, healthwise, etc., but ...

If we have a goal of depleting the energy stores in our liver, you're interrupting (and perhaps) sabotaging that.

OR, if we are trying to restrict calories into a certain time window, you've opened up that window with the butter and the milk. You're no longer in the 16, you're in the 8 (so to speak).

It is a common misconception that any calories >0 break the fast. However, all IF coaches agree that the threshold for most people is around 50 calories [1]. Knowing this, I only take a splash of cream or milk in my coffee.
