I read this recently and I am wondering if anyone has any documentation or information about this. I have never heard of it but think it's very interesting. Thanks in advance.

It was previously thought that new fat cells were formed only during infancy and puberty. This could explain why so many women who never had weight problems suddenly have them after pregnancy. "
