Thank you, CruiseChick, assuming addressing me.
I sent an email to MF and a dietitian responded by the next morning. She said the goal is 40% protein, 40% carbs and 20% fat, which I programmed into My Fitness Pro app, which, btw, isn't achievable until factoring in the one real food meal.
At this point, I'm extremely impressed by Medifast. The welcome package is well thought out and wasn't done on the cheap ... I like that.
