Attitudes toward over-indulgence, obesity and body shape were being hotly debated and used for political purposes as early as the 19th century, a new book claims. ‘Pathological Bodies’, by Dr Corinna Wagner from the University of Exeter, shows that body consciousness is not just a modern-day phenomenon.
Instead, medical warning about excessive eating and drinking, and public attitudes about self-control and discipline emerged more than 250 years ago, when the perceived decadence of the Georgian period gave way to the more moderate and austere approach adopted by the Victorians. (more…)
Researchers had known for several decades that a certain chemical modification exists on messenger ribonucleic acid (mRNA), which is essential to the flow of genetic information. But only recently did experiments at the University of Chicago show that one major function of this modification governs the longevity and decay of RNA, a process critical to the development of healthy cells.
The chemical modification on mRNA in question is called N6-methyladenosine (m6A). A recent study by UChicago scientists reveals how the m6A modification on mRNA could affect the half-life of mRNA that in turn regulates cellular protein quantities. That discovery could provide fundamental insights into healthy functioning and disorders such as obesity, diabetes and infertility. (more…)
For youth dealing with obesity who need extra help losing weight, experts suggest a multidisciplinary approach in which care is provided by several health specialists. However, the logistics of traveling to multiple appointments, even if just across town, can be a barrier to receiving care, especially for low-income families.
UCLA researchers who work with this patient population set up a pilot program using telehealth technology — a secure system that allowed patients to see and speak with their health care providers at UCLA over a computer from their local health clinic — to evaluate if such a system could be an effective strategy to help overcome these issues.

Asian Indians are one of the fastest growing ethnic groups in the United States, and roughly half a million people of Indian ancestry live in California — more than any other state. Individuals from this group are strongly predisposed to obesity-related conditions such as diabetes and heart disease, due in large part to physical inactivity, diets low in fruit and vegetables, and insulin resistance.
Among other racial and ethnic groups, research has shown that religious practices and religiosity have been associated with obesity and greater body weight, but no one had studied this potential link among Indians. (more…)
In a new discovery reported in the Journal of Biological Chemistry, Brown University and Lifespan researchers show that in the brain cells of rats, obesity impedes the production of a hormone that curbs appetite and inspires calorie burning. The root cause appears to be a breakdown in the protein-processing mechanism of the cells. In the lab, the researchers showed they could fix the breakdown with drugs.(more…)
Born slightly heavy on average, a sample of hundreds of infants in American Samoa continued to gain weight quickly after birth, achieving high rates of obesity within 15 months. Breastfeeding slowed weight gain in boys. Findings may presage infant obesity in other populations where obesity is increasing population wide.
PROVIDENCE, R.I. [Brown University] — As some Pacific island cultures have “westernized” over the last several decades, among the changes has been a dramatic increase in obesity. Researchers don’t understand all the reasons why, but even a decade ago in American Samoa 59 percent of men and 71 percent of women were obese. A new Brown University study finds that the Samoan epidemic of obesity may start with rapid weight gain in early infancy. (more…)
WASHINGTON — On average, Americans die sooner and experience higher rates of disease and injury than people in other high-income countries, says a new report from the National Research Council and Institute of Medicine.
The report finds that this health disadvantage exists at all ages from birth to age 75 and that even advantaged Americans—those who have health insurance, college educations, higher incomes and healthy behaviors—appear to be sicker than their peers in other rich nations. (more…)
The MU study is not claiming that BPA is safe, but that the previous series of studies are not reproducible.
COLUMBIA, Mo. — Following a three-year study using more than 2,800 mice, a University of Missouri researcher was not able to replicate a series of previous studies by another research group investigating the controversial chemical BPA. The MU study is not claiming that BPA is safe, but that the previous series of studies are not reproducible. The MU study, published in the Proceedings of the National Academy of Sciences, also investigated an estrogenic compound found in plants, genistein, in the same three-year study.
“Our findings don’t say anything about the positive or negative effects of BPA or genistein,” said Cheryl Rosenfeld, associate professor of biomedical sciences in MU’s Bond Life Science Center. “Rather, our series of experiments did not detect the same findings as reported by another group on the potential developmental effects of BPA and genistein when exposure of young occurs in the womb.” (more…)
