I've seen that too.
These types of diets can also be hard on thyroid so anyone not already under a doctor's care for thyroid, I'd suggest having it checked, especially if you are going to be on the plan more than 3 months.
I was way colder than I'd ever been & my thyroid numbers were way out of whack after 4 months on plan.
