Low Carb Diets and Thyroid Hormones

The one issue you've heard about hypofilamic amenorrhea in females who are energy restricted, maybe they're high intensity athletes or people who are anorexic can lose their period. Some of those females, and there's a genetic component too, because it doesn't happen everybody, there's not all of those females recover their period. So that's why I've said you could argue there's some evidence of something like metabolic damage, but not in the way that our friends online like to argue about in the dieting world with thyroid and stuff.
