Yep...and it is exactly this mechanism that makes it so hard for women to lose. Our bodies are extremely adept at adjusting our metabolisms to the conditions at hand to protect our 'child bearing' abilitites. Not only does estrogen play a role, but so do a whole host of other hormones that are constantly working against us when we try to slim down. It goes against the basic nature of the female body to attempt to lose weight!

Sucks for modern day life in countries where food is not in shortage though, doesn't it!?!
