Most normal-weight women -- almost 90 percent in a Cornell study of 310 college students -- yearn to be thinner. Half of underweight women want to lose even more weight, or stay just the way they are, thank you very much.
Meanwhile, most overweight women don't want to be thin enough to achieve a healthy weight.
According to the study, one of the few to quantify the magnitude of body-weight dissatisfaction, which was published recently in the journal Eating Behaviors, most -- 78 percent -- of the overweight males surveyed also want to weigh less. But of this group, almost two-thirds -- 59 percent -- do not want to lose enough, so the body weight they desire would still keep them overweight.
More than 60 percent of U.S. adults are considered overweight or obese. And "because they don't meet the societal ideals propagated by the media and advertising for body weight, they are often targets of discrimination within educational, workplace and health-care settings and are stigmatized as lazy, lacking self-discipline and unmotivated," says Lori Neighbors, Ph.D. '07, who conducted the research with Jeffery Sobal, Cornell professor of nutritional sociology in Cornell's College of Human Ecology.
These factors have led many people to be dissatisfied with their bodies, says Neighbors, now an assistant professor of nutrition at the University of Wisconsin, Milwaukee.
When the Cornell researchers assessed body weight versus the weight and shape individuals wish they had, they found that:
Most of the normal-weight women who want to weigh less desire a weight still within the normal-weight range. However, 10 percent want to weigh what experts deem as officially underweight.
Half of the underweight women want to stay the same or lose weight. "The majority of underweight females, closer in body size to the thin cultural ideal, consider their body weight 'about right,'" said Sobal, even though experts have deemed these body weights unhealthful.
Overweight women want to weigh less. But about half want a body weight that would continue to make them overweight.
The findings suggest "that the idealized body weight and shape, especially among underweight females and overweight individuals of both genders, are not in accordance with population-based standards defining healthy body weight."
In a society in which excess weight is the norm, it's vital, say the researchers, to better understand body dissatisfaction and how this dissatisfaction impacts weight-management efforts.
"While both men and women express some degree of body dissatisfaction, a surprising proportion of people with less healthy body weights -- underweight females and overweight individuals of both genders -- do not idealize a body weight that would move them to a more healthy state," said Neighbors.
The research was supported primarily by the National Institutes of Health.

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.
From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
