Especially, It Seems, Beginners

1 We’re Walking More, but Not Enough

According to CDC data, the number of Americans who say they walked for ten or more minutes at least once in the past week has increased by an impressive 15 million people since 2005, from 56 percent of U.S. adults then to 62 percent now. However, the average amount of time that people say they spent walking actually fell a bit, from 15 minutes per day down to 13 minutes. CDC officials, who interviewed over 45,000 people, attribute the inconsistency to most of the new walkers starting with brief strolls and thus lowering the overall average walk time. Adults who report that they meet federal fitness guidelines -- 75 weekly minutes of vigorous activity (jogging, swimming) or 150 minutes of moderate activity (brisk walking) -- rose from 42 percent in 2005 to 48 percent in 2010.

As Much As 34 Percent

2 Weight Training Cuts Diabetes Risk in Men

Weight training can reduce the risk of type 2 diabetes in men by as much as 34 percent, finds a Harvard University study of more than 32,000 men who lifted weights for at least 2 1/2 hours per week. While previous studies showed the beneficial effects of aerobic exercise on the prevention of diabetes, this was the first to study weight training and show that it has benefits independent of aerobics, says lead author Dr. Frank Hu. Weight training builds muscle, which is important for metabolism and insulin sensitivity. Aerobic exercise burns fat, which is a major risk factor for type 2 diabetes. "The most important message from this study is that combining the two types of exercise confers the largest benefit," says Hu. It was linked to a 59 percent reduction in diabetes risk.

Different Condition, Treatment

3 Type 1 Diabetes Often Misdiagnosed As Type 2

As the diabetic population continues to grow, many adults with type 1 diabetes are being misdiagnosed with type 2, reports The Wall Street Journal. Type 1 is an autoimmune disorder that attacks the body’s ability to produce insulin that must be replaced daily. Type 2 diabetes is brought on by inactivity and obesity and can often be managed with lifestyle changes. It may be treated with oral insulin although some type 2 diabetics require insulin injections. It’s estimated that there are 1.3 to 2.6 million Americans with type 1 diabetes, and that figure is rising by about 2.5 to 4% a year for unknown reasons. The WSJ reports that misdiagnoses are often by primary care physicians, many of whom haven’t received adequate education about the rising incidence of adult onset type 1 diabetes.
