This here is an Early Grey with milk addict. Been so for erm, 40 years. The odd coffee I also had with lots of milk, no sugar either.
Started Keto 4 weeks ago and was introduced to BPC. Complained about the cost of MCT oil (30+ Euros per litre!), so my nutritionist said: “start with 15-20mg of desodorised coconut oil”. That’s the coconut oil that has no taste to it. I did, not forgetting about my milk, and for the first time I quite like coffee in the mornings. It actually replaced breakfast (that I never had either). So in the mornings, I have my normal cuppa and around 10am I have this pseudo BPC coffee. It really does help me through midday, not feeling hungry at all. I have a small meal around 2 pm and then dinner around 5pm. No cravings in between or in the evenings.
So yes, BPC or my version of it, tells my body there is no need for “food”.
My nutritionist told me to avoid MCT oil as a beginner, as it tends to make people vomit front or back, and when I start taking it (after 10 weeks into keto eating), I should take it SLOW.
