In this week's episode of Fit Fat Fast, we answer listener mail and talk about why cheating and/or fast-tracking metabolic efficiency is bad, what to eat during two-a-day training (spoiler: nothing special), what goes into a fat smoothie and we answer more questions about Maffetone training.

We wrap up with some clips from a webinar Debbie did with the guys from Generation Ucan talking about race fueling and more info about why fat is the body’s preferred source of fuel. Enjoy!
