I happen to have a lesbian niece...very beautiful, trim and fit....she never played sports and was a very feminine young woman...
The number of people who can attribute their obesity to hormonal issues is miniscule compared to the number who simply eat too much. Maybe it’s possible that lesbians tend toward a co-morbidity of hormonal imbalances and weight gain. That is an interesting research question (that will never be pursued).
It’s remarkable how hormonal imbalances can be spotted in a supermarket checkout line.
