...obesity rate rises, it's not just waistlines that are expanding. The cost of medical care has ballooned, according to a new report in the policy and research journal Health Affairs. The study's authors compared medical data from 1998 and 2006 and found that obese Americans--who now make up a quarter of the U.S. population--are responsible for a $40 billion jump in annual medical spending. Obese people spend $1,400 more a year than people of normal weight on medical services, according to research data. Medicare doles out $600 more for obese beneficiaries; Medicaid pays $230 more...
...Last year the International Journal of Obesity published a paper by Gortmaker and Kendrin Sonneville of Children's Hospital Boston noting that "there is a widespread assumption that increasing activity will result in a net reduction in any energy gap" - energy gap being the term scientists use for the difference between the number of calories you use and the number you consume. But Gortmaker and Sonneville found in their 18-month study of 538 students that when kids start to exercise, they end up eating more - not just a little more, but an average of 100 calories more than they...
...Sure. It does plenty. In addition to enhancing heart health and helping prevent disease, exercise improves your mental health and cognitive ability. A study published in June in the journal Neurology found that older people who exercise at least once a week are 30% more likely to maintain cognitive function than those who exercise less. Another study, released by the University of Alberta a few weeks ago, found that people with chronic back pain who exercise four days a week have 36% less disability than those who exercise only two or three days a week...

Interestingly, until the 1970s, few obesity researchers promoted exercise as critical for weight reduction. As recently as 1992, when a stout Bill Clinton became famous for his jogging and McDonald's habits, the American Journal of Clinical Nutrition published an article that began, "Recently, the interest in the potential of adding exercise to the treatment of obesity has increased." The article went on to note that incorporating exercise training into obesity treatment had led to "inconsistent" results. "The increased energy expenditure obtained by training...
