Between tampons/pads, bras, thinner/less quality clothing for as much or more $$$, and socially pressured skincare/makeup/hair product, the overall cost I would guess would be equivalent or more than the nutrition for a few hundred calories per day. There are a lot of factors forcing or pressuring women to spend more money or recieve social reprimand, lowered job prospects, etc. (As in the article! Keeping girls in school!)

Men also get pressured in other ways, but very rarely are they directly monetary/consumptive the way women are in my opinion.
