The key to really good bulletproof coffee I've found is a good immersion blender at the end. BP is grass fed butter and coconut oil. I also add a touch of half and half.
It is delicious. And filling and energizing and healthy. LOVE IT.
Make sure any you get is organic and virgin. It is a nice energy boost and filling is why people use it in the gym.
People generally loose more weight when using it. If they say have 200 calories of coconut oil a day they might cut 400 calories elsewhere it is so filling.
And no problems frying with it unlike olive oil. Just SUPER healthy.
