As diet is a controllable factor, the influence of re-feeding with different dietary patterns on bone parameters is important to study. Resveratrol has been attributed a number of beneficial effects in mammals including osteotrophic properties. In the March 2012 issue of Experimental Biology and Medicine Wang and colleagues describe the first study to describe the effects of CUG, with different diets, on bone status and the role of resveratrol in CUG models. http://medicalxpress.com/news/2012-03-effect-catch-up-growth-diets-resveratrol.html Medical research Wed, 07 Mar 2012 10:31:17 EST news250338664 Scientists at King's College London and the National Diabetes Centre (Sri Lanka) have found evidence of a high number of risk factors for type 2 diabetes among the young urban population in Sri Lanka.

Elucidating the biological mechanism that links overnutrition to obesity could prove crucial in reducing obesity levels. In the July 26 issue of PLoS Biology, Dr. Dongsheng Cai and his research team at Albert Einstein College of Medicine describe a pathway that directs the brain to sense the body's glucose dynamics, and they find that a defect of this glucose sensing process contributes to the development of obesity and related disease. Importantly, the team also found that correction of this defect can normalize the whole-body energy balance and treat obesity. http://medicalxpress.com/news/2011-07-obesity-brain-glucose.html Medical research Tue, 26 Jul 2011 17:27:25 EST news230919926 Researchers from the United States and Europe involved in an NIH-funded multicenter study have determined that increased body mass index (BMI) is an independent predictor of clinical decompensation in patients with compensated cirrhosis, independent of portal pressure and liver function. The findings suggest obesity accelerates cirrhosis progression and measures to reduce BMI could improve the prognosis for patients with advanced liver disease.
