Women cannot claim that they “get it [large butts] from their momma’s” anymore. Researchers in London found that the pressure put on areas of the body used for sitting or lying down produces up to 50 per cent more fat in those parts.

This can explain why couch potatoes and other sedentary behavior makes you fat when combined with a lack of exercise.

But even those with healthy diet and exercise habits will be affected if they spend long periods sat behind a desk.

Researchers found that preadipocyte cells – the precursors to fat cells – turn into fat cells and produce even more fat when subject to prolonged periods of ‘mechanical stretching loads’ – the kind of weight we put on our body tissues when we sit or lie down.

The researchers noted the development of liquid droplets in both the test and control groups. However, after just two weeks of stretching, the test group developed significantly more – and larger – droplets.

By the time the cells reached maturity, the group that received mechanical stretching had developed fifty per cent more fat than the control group.

Professor Amit Gefen, from Tel Aviv University, said: “Obesity is more than just an imbalance of calories. Cells themselves are also responsive to their mechanical environment. Fat cells produce more triglycerides [the major form of fat stored in the body], and at a faster rate, when exposed to static stretching.

“There are various ways that cells can sense mechanical loading. It appears that long periods of static mechanical loading and stretching, due to the weight of the body when sitting or lying, has an impact on increasing lipid [fat] production.”

  1. but the curve is inherited

    African-American women are not the only race of women with large asses! Now they have yet another stigma to overcome, laziness! I think you could have stated your point without brining race into play!

  3. “DATS A DAMN LIE”…AS WELL AS A SHAME..ALL THE MONEY THEY SPENT ON THIS SILLY ASS ACCUSATION COULD HAVE WENT TO SOMETHING ELSE MORE WORTH IT LIKE CHERITIES, OR ALL I CAN SAY IS THAT IF U DONT HAVE ONE U CANT KNOW WHERE IT COMES FROM.. NO MATTER WHAT POTIONS U MIX TOGETHER..HELL I WAS BORN WITH A BIG BUT SO WHAT YOU SAY NOW.. I MUST HAVE BEEN LAYING OR SITTING ON IT IN THE WOMB? GET REAL!! IF ANY THING U GET A FLAT BUTT FROM LAYING OR SITTING ON IT CUZ U KILLING ALL THE CELLS AND SUFFOCATING THEM.. AND THEY RUN TO THE OTHER PART OF THE BODY.. SUCH AS LEGS AND ANKLES AND “GUT”.. NOW HOW U LIKE THAT FROM THE OFFICES OF BIGBOOTIESROC

  4. Does this mean that if my ass is flat, I can fatten it by sitting on it. Sounds good!

  5. Wow why the hell are there so many comments defending being obese. GET OFF THE INTERNET AND GO EXERCISE.

  6. Although that first line was offensive and also unnecessary (and I’m small), I’ll ignore it and say that this really isn’t a surprise…sitting too much makes you fat. No surprise there.

  7. Yeah, race has nothing to do with this study. Race was not even mentioned. AND, note that the studies were done in London and a professor from Tel Aviv chimed in, so I am sure when looking at the fat cells producing more triglycerides, they did not mention any race have any predispostion to hyper development. Bottom line, move it and lose it! : )

    • @judi:

      Judi, why did you say race wasn’t mentioned when the very first line in the story, when it starts underneath the photo, is:

      “Black women cannot claim that they…”

      Race was the FIRST thing brought up in the story.

      Geez I know you were probably speaking specifically to the study itself, but the way this story is written directly take shots at blacks. And very rudely.

      This whole page is poorly presented really. I know plenty of ladies who are quite fit with curvy predominant rears. That kind of shape and size appears to definitely come from whatever genetic blessings the person inherited.

  8. once again we are not lazy three third’s of america is fat wanna know why over abundance of food
