You forgot the blah blah blah, PMS give me salt and chocolate and I won't rip your head off and don't even THINK about the scale right now or I will make you listen to me as I disparage myself about my fat
Darth Pooh - actually, there are real, hormonal reasons why a woman's body looses weight more slowly than a guy's. Sure the law of energy balance applies, but a woman's body is more adapted to hold on to fat for reproductive and infant rearing purposes. Also, when a woman hits peri-menopause and full menopause, the imbalance in the hormones really slows the process down.
It's not so much a matter of harder to loose weight - but women definitely are the tortoises in the weight race, not the hares

It can be very discouraging to be doing the same things as your male counterparts(creating a calorie deficit in keeping with your body's needs, observing good nutrition and doing several hours of cardio and strength training exercises each week) and only seeing a fraction of the results they see. It isn't that the principles don't apply to us, it's just that we don't respond as quickly as the guys do when we put those principles into practice.
Not smacking you down, just adding my 2 cents
God Bless,
