Ghrelin, a hormone that stimulates appetite, was administered to older women diagnosed with frailty, a common geriatric syndrome characterized by unintentional weight loss, weakness, exhaustion and low levels of anabolic hormones which increases risk of falls, hospitalizations, disability, and death. Those who received ghrelin infusions consumed 51 percent more calories than the placebo group, with an increase in carbohydrate and protein intake, not fat. Their growth hormone levels were also higher throughout the ghrelin infusion. http://www.physorg.com/news164034755.html Medicine & Health Fri, 12 Jun 2009 14:12:53 EST news164034755 Vitamin D levels in the body at the start of a low-calorie diet predict weight loss success, a new study found. http://www.physorg.com/news163950079.html Medicine & Health Thu, 11 Jun 2009 14:41:45 EST news163950079 In teenagers, laparoscopic gastric banding surgery for treatment of extreme obesity can significantly improve and even reverse the metabolic syndrome, a new study found. http://www.physorg.com/news163946909.html Medicine & Health Thu, 11 Jun 2009 13:49:01 EST news163946909 After weight loss surgery, people have nearly twice the expected risk of breaking a bone and an even higher risk of a foot or hand fracture, a new study has found. http://www.physorg.com/news163939075.html Medicine & Health Thu, 11 Jun 2009 11:38:32 EST news163939075 In combination with diet and exercise, the diabetes drug exenatide helped nondiabetic, obese individuals lose over three times more weight than those receiving a placebo, or dummy treatment, for 6 months. http://www.physorg.com/news163938330.html Medicine & Health Thu, 11 Jun 2009 11:25:54 EST news163938330 A modest reduction in the amount of carbohydrates eaten, without calorie restriction and weight loss, appears to increase a sense of fullness, which may help people eat less, a preliminary study found. http://www.physorg.com/news163911999.html Medicine & Health Thu, 11 Jun 2009 04:06:49 EST news163911999 Researchers at Imperial College London have identified a new appetite suppressant for promoting weight loss that they say works in rodents and may one day be used to develop an effective anti-obesity treatment. http://www.physorg.com/news163850449.html Medicine & Health Wed, 10 Jun 2009 11:50:01 EST news163850449 Overweight individuals who ate a low-calorie, low-carbohydrate diet high in plant-based proteins for four weeks lost weight and experienced improvements in blood cholesterol levels and other heart disease risk factors, according to a report in the June 8 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
