2 years ago I started drinking Bullet proof coffee in the morning and not eating anything solid until after 12:30pm. I wake up around 6am so between 6am and 12:30am I drink only water as well as a bulletproof coffee (recepie below). I literally lost 13 lbs in a matter of doing this for 2 months straight. I continue to practice this routine today!
1.5 cups of a dark roast hot coffee
1 tbsp MCT oil (find at Wholefoods or any health food store)
1--1/4" square slice of Kerrygold butter or any organic grassfed butter
