Bullet Proof Coffee

Hey Brooke! What do you think of bullet proof coffee? I have been drinking it for a while and love it. I drink coffee with 1TBS grassfed (Kerrygold) butter and 1 TBS virgin coconut oil from trader joe’s. I read somewhere that pure fat like this doesn’t trigger an insulin response and can be a great tool to integrate into fasting. I drink it in the morning instead of breakfast and then fast until 2 or 3pm.

My question is – what are your thoughts on bulletproof coffee in general?
And if I have that in the morning, am I still fasting? Should I cut it out?

I lost about 5 lbs in the first 2 weeks, for context. I am 5’9″ and currently 158 lbs.
