Insulin Resistance Reversed By Removal Of Protein
By removing the protein galectin-3 (Gal3), a team of investigators led by University of California School of Medicine researchers were able to reverse diabetic insulin resistance and glucose intolerance in mouse models of obesity and diabetes.

New research published in the British Journal of … [Read more...]
Obesity May Be A Disease Of The Brain
Obesity may ultimately be a disease of the brain, involving a progressive deterioration of various cognitive processes that influence eating. Researchers at Macquarie University have now shown that memory inhibition -- the useful ability to 'block out' memories that are no longer useful, which depends on a brain area called the hippocampus -- is linked to dietary excess. … [Read more...]
Early To Bed Cuts Risk Of Obesity Later
Preschoolers who are regularly tucked into bed by 8 p.m. are far less likely to become obese teenagers than young children who go to sleep later in the evening, new research has found.

How lifestyle intervention for weight loss affects birth rates in women?
Women who are overweight or obese pose an ongoing challenge for the fertility clinic. Many studies show that these patients are at increased risk of infertility and are less likely than normal-weight women to conceive after fertility treatment. For example, ovulating sub-fertile women with a body mass index (BMI) of 29 kg/m2 or higher have been found in one study to have a 4% … [Read more...]
Switch-Off Your Cravings
Eating a type of powdered food supplement, based on a molecule produced by bacteria in the gut, reduces cravings for high-calorie foods such as chocolate, cake and pizza, a new study suggests. Scientists from Imperial College London and the University of Glasgow asked 20 volunteers to consume a milkshake that either contained an ingredient called inulin-propionate … [Read more...]
Calorie-burning Pathway found in Fat Cells
Investigators at Dana-Farber Cancer Institute in collaboration with scientists at the University of California, Berkeley, have identified a natural molecular pathway that enables cells to burn off calories as heat rather than store them as fat. This raises the possibility of a new approach to treating and preventing obesity, diabetes, and other obesity-linked metabolic … [Read more...]

Adolescent weight linked to heart failure in early middle age
Surprisingly, the increased risk of heart failure was found in who were within the normal body weight range (a body mass index of 18.5 to 25) in adolescence, with an increased risk starting in those with a BMI of 20 and rising steeply to a nearly ten-fold increased risk in those who were very obese, with a BMI of 35 or over. The study, which is published in the European … [Read more...]
