Scotty,
My ex boyfriend told me a couple years ago that ketosis lowered T3 levels........he always recommended running at least 12.5mg to 25 mg with the diet just to help kick the fat burning up a notch.
Therefore, he said, people need to carb up every two weeks for two days.....to replenish the carbs the thryroid needs.
He use to play pro ball in his 20's (now 38 yrs old) along time ago and has been into strength and endurance training for the last 5 years for a local team..........and does some personal training too..........
so, I took his word for it.
What is the reason you carb up every two weeks or so???
