Too low bodyfat?
From what I’ve heard, women who get and stay below 10-12% bodyfat, depending on their individual thresholds, frequently stop producing normal amounts of estrogen. The most common side effects are cessation of the menstrual cycle, which isn’t so bad unless you’re trying to get pregnant, and loss of bone density, leading to frequent stress fractures. Women who are attempting to maintain such low levels of bodyfat should get some supervision from a sports doctor, and women who are plagued with stress fractures might want to get their bodyfat checked.
