Not trying to start a fight. I was merely pointing out that saying "always" is false. Theres a lot of factors that go into how one carries fat other than their sex chromosomes. Period. That's all I was pointing out.
Actually, gynecomastia affects up to 60% of young men in puberty to some extent (
SOURCE), and studies show that as many as 30% continue with some recognizable form of gynecomastia into adulthood, ranging from enlarged nipples to actual breast tissue.
A lot of females just don't have this large amount breast tissue that causes the higher body fat percentage. Plenty of females have AA cup breasts (which amounts to almost no extra body fat), especially after all of the weight loss that tends to come concurrent with weight training and body building.
Bodies are not so easily definable by just one set of genetic characteristics, and I just think that if breast tissue is what causes the higher body fat percentage, maybe we should try to say "people with breast tissue" instead of just saying females and try to be a little bit more accurate with our terminology.
It's just my $0.02, and prior to that post, I don't think we really knew the body type of the OP. Now we know that she has what may fall in line with a more "typical" female build, but you didn't know that before and saying "always" can be very misleading.
Also, you know, she was asking why her sense of her own body fat was so off from the calculations of her body fat, and having a body type that doesn't fit neatly into the "typical" body that those body fat calculators assume could have been an explanation. It has been a source of frustration for me in my life, and I'm sure I'm not the only one. Informing someone how those calculators work and the assumptions they make is actually perfectly on topic.
