I've been listening to a few items recently that specifically focus on women's health, and there are apparently quite a lot of differences in how diets work for men and women, beyond the calorie allowances we're all aware of, so I though I should pass some information along.
Calorie controlled diets/fasting supposedly raises ghrelin levels in both men and women (this is the hunger signal), which makes women more "hangry" than men. Higher levels of Ghrelin result in lower levels of thyroid hormones, specifically something called T3, which is mostly what drives your metabolism.
A study put women on 1200 calories/day, and found their T3 levels dropped by 40%, while a sub group were restricted further to 400 calories/day, and their levels dropped by 66%:
The other diet mentioned was keto, which they said can be an issue for pre-menopausal women (not necessarily every woman), because women can often benefit from higher levels of carbs in the early half of their cycle. I am mostly taking their word for this one, but did find this article (not read closely from beginning to end):
I'd be curious what other's experiences are with this, or if anyone has any information to counteract?
