as a more serious answer:
there is really no comparable performance enhancer like losing weight
for the majority of runners that aren't already/naturally extremely lean, it's more effective to lose significant weight than it is to use a gold standard oxygen vector substance like EPO
because of this fact, combined with women tending to be more attractive when on the leaner side in an otherwise obese world, women and girls are at somewhat extreme risk of compromising their health mostly unconsciously in the pursuit of athletic, social and sexual relevance/advancement
there are an order of magnitude more horror stories (almost every top female hs distance runner ever) than success stories (many successful female pros were not quite the best of the best in hs, though almost always very close)
the result is that discussion is highly censored, though i totally understand it's for the best intentions, even if i don't agree as it's my opinion ignorance only perpetuates the problem
