Strong french press coffee, add two table spoons each of grass fed butter, organic coconut and MCT oil and one teaspoon of any one of several different mushroom powders made by Paul Stamets. Early in morning, so make sure you put the lid on the Vita-Mix before you turn it on, or your warm up will consist of washing power coffee off of the ceiling and walls. This mix and a few different amino acids will be sole calorie intake until 11a or noon. I've tried many different types of quality loose and powdered green teas. I feel better with the coffee mix. I'm sure being addicted to caffeine has nothing to do with it. I might also have a packet of Workout Crusher by Eboost ( 175mg. caffeine). Yeah, no problem here.
And from time to time I will mix in a couple table spoons of Death Wish Coffee in with my regular beans.
