Why only one cup of coffee? Is it the caffiene? Does decaf apply here too? (I work in coffee and often skip breakfast.)
Good question! I'm sorry I left out the details. Yes, it is the caffeine and the book I followed (The Renegade Diet by Jason Ferrugia) recommends 1 cup about 30-45 mins before the workout to burn fat even faster.
Even though I now rarely work out before going to work, I still start my day by drinking a glass of water and then a cup of coffee and it still feels good :) If you drink decaf, I think it would have no positive (but probably also no negative) effect.
That way you keep insulin under control for the 20 hours (out of 24). Your concentration and focus will increase very soon.
