Obesity is a huge problem in the United States, and it’s linked to serious illnesses such as diabetes, stroke, heart disease and certain cancers.
A new report suggests that by 2030 nearly half of all Americans will be obese, and these expanding waistlines will translate into billions of dollars of health care costs. The study authors advocate for nationwide interventions to get children and adults to be more physically active and eat healthier.
More than 400 readers commented on the story. The most popular reader comment came from Joe Skinner, who says:
Bruce Force responded that weight loss alone won’t solve the problem:
Chichetr proposed the radical measure of taxing overweight people per pound, a comment that got 59 “likes” :
But pgauthi responded with a more pragmatic approach:
Delishus Cake represented the point of view that the high cost of healthy foods compared to fattening foods is part of the problem:
But halfthestory argues the opposite viewpoint:
Finally, the usage of body mass index as a measure of obesity is imperfect, as readers such as CatMagnet noted. Height and weight are the factors that go into calculating BMI, but for some people that is not an accurate assessment of whether they are healthy.
On Twitter, science writer @miriamgordon responded to the story by citing this New York Times article from Tuesday, which notes that obesity as we know it may not be the whole story: “In study after study, overweight and moderately obese patients with certain chronic diseases often live longer and fare better than normal-weight patients with the same ailments.”
Part of the problem is that if you measure obesity with body mass index, you are ignoring other potentially critical measurements of health, including metabolic abnormalities, lean muscle mass and body fat, the article said.
Another science writer, @daviddespain, responded with an article he had written on his blog suggesting that young Asian-American women may be improperly categorized as healthy using the traditional BMI scale; they may have low BMI but high body fat percentage.
The state-by-state obesity data from the Centers for Disease Control and Prevention do not take these deviations from the traditional BMI picture into account, nor do the 2030 predictions.
