Well I have my own version which these days is just a triple shot americano with 2 tablespoons of double cream. I have had the butter and coconut oil version but these days don't bother. Yes its fine as a meal replacement and will keep you full all morning. I never had the "official" BPC with Dave Asprey's goods as I'm not sure I entirely like his or his ethos. I reckon home made is just as good. If you are making hot chocolate just watch out for added sugar if using powder. I think they are usually sweetened with nasties.
