I'm on Plan F with adrenal/thyroid issues. I have low cortisol in morning and high at night which should be reversed. I’m also waking up 1-3 a.m. Which animal protein and plant protein can be used in morning smoothies for those of us in this situation?

Try Fit365 or Tera's Whey protein powder in the morning. Studies show that protein-loading up to 30G within one hour of waking is most effective to balance cortisol levels ALL day and night (important for those with insomnia). What you do the first hour of waking will set the tenor for your entire day.
