Person’s medical costs rise with increasing obesity

Overweight and obese individuals incur up to $1,500 more in annual medical costs than healthy-weight individuals, according to a two-year study of nearly 200,000 employees of General Motors. Average annual medical costs for normal weight individuals in the study were $2,225, while costs for overweight and obese individuals rose steadily, from $2,388 for overweight individuals to $3,753 for the most severely obese persons. The study, by Dee W. Edington, Ph.D., of the University of Michigan and colleagues, is the first to examine the relationship between medical costs and the six weight groups defined by the National Heart, Lung and Blood Institute’s weight guidelines. The guidelines separate individuals into categories of underweight, healthy-weight, overweight and three different obesity designations, based on average body mass index.

High-carb supplement helps with weight loss, MIT researchers say

MIT researchers have reported that a high-carbohydrate dietary supplement can help patients who experience weight gain while taking antidepressants. Even though the high-carbohydrate regimen altered serotonin levels, it did not alter the antidepressants’ effectiveness. The regimen, which includes a high-carbohydrate drink developed at MIT based on research conducted here, also helped non-medicated obese individuals, the researchers reported. All participants lost between 12 and 26 pounds during the 12-week study. Patients taking psychotropic medications such as antidepressants that increase the activity of serotonin in the brain sometimes gain weight by overeating sweet and starchy foods.
