Replacing obesity with malnutrition will still leave you unhealthy but with different health problems. Also hormone imbalance isn't unscientific. It has been widely been studied that women will have their periods change timing when malnourished. Anectdotally: I had my testosterone levels wiped out when switching from a diet with excess calories to a one with not enough calories and nutrients. The condition fixed itself when I started practicing a balanced diet (with exercises).
