A small number of extremely overweight people may be missing the same chunk of genetic material, claim UK researchers.  The findings, published in the journal Nature, could offer clues to whether obesity can be “inherited” in some cases.  Imperial College London scientists found dozens of people – all severely obese – who lacked approximately the [...]

Advantages of group treatment and structured exercise in promoting short-term weight loss and cardiovascular risk reduction in adults with central obesity.

Previous data suggest that group obesity treatment results in greater weight loss than individual treatment. Whether exercise with calorie restriction results in significantly greater weight loss as compared with calorie restriction alone remains unclear. We evaluated the impact of self-selected group intervention, with and without exercise, on body mass index (BMI) and cardiovascular risk factors. [...]

School-based exercise program improves fitness, body composition and cardiovascular risk profile in overweight/obese children.

This study determined the effect of a school-based exercise training (ET) without dietary intervention, on body composition, fitness and cardiovascular risk in overweight/obese children. Subjects were 51 overweight/obese 6.5- to 12.5-year-old children, of whom 48 completed the program. Participants were enrolled in a 15-week aerobic training (three 60-minute sessions/week). Working heart rate was between 120-185 [...]
