Starve meaning eating 1000-1200 calories a day, not literally none. But yeah, hang around here awhile and eventually you'll find this happening to someone. Usually a woman. I just think it really throttles back thyroid production when they do it.

When I was hypothyroid I ate 1200 calories a day and walked an hour a day (at least) and never lost a thing. So if over-exercising under eating does the same thing then I can definitely see that happening.
