Why do most american women suffer from obesity?

Most lilkely because most american women lack self control, evade responsibility, and think they have a cultural right to be supported by society regardless of personal merit simply because they are women. Pretty much the same problems american men have (except for the "because they are women" part) that make the majority of them obese as well. :)

Just greediness really. Far too many fast food take aways in America. Bring back fresh food!
bcoz they eat lots of fast foods, bread butter,and sit for hours and hours on one places at there work.they use many electrical appliance so they dont do any work by there hands.
I'm not sure it's "most", but it's not just women. Many americans of all types suffer from obesity simply because of their diet. That's why there's so much illness due to poor health. Diabetes is at epidemic proportions. My doctor told me "You should eat to live, not live to eat". Good advice. I've lost nearly forty pounds and feel great after learning how to eat properly.
Simple: Calories of intake and quality of intake is too high...and good...Of course climate does not help digesting the same...
well for some reason women suffer from obisity is that they are not cutting back on the caliorys and the fat acids which means like hamburgurs and fries are like 500 caloriys a pice and thet will be 1,000 in just one day u post to have 2,000 daily caloriys for a diet and somtimes people can not exersise becouse they cant harly move they get lazy if u just cut back on the fat acids and maybey eat like salads and friut u will sure will lose wait and walk around well thats all i have today
I am overweight, I don't just sit all day long, and do nothing. I have 3 kids a part time job, a youth group, so I do move. And I am not a big fast food eater either. Yes I need to eat less and do more, but that is really unfair to generalize like that.
