These days, most adults are overweight, not active, or both. If you could change just one—become active or lose weight—which would be better?
At least for men, being more fit may have a bigger health payoff than losing weight, according to a new study of more than 14,000 well-off middle-aged men who are participating in the Aerobics Center Longitudinal Study. Researchers followed their health, weight, and exercise habits for 11 years. They estimated how physically fit the men were by calculating their metabolic equivalents (METs) from a treadmill test.
Compared with men whose fitness declined over the course of the study, those who maintained their fitness levels reduced their odds of dying from cardiovascular disease or any other cause by about 30%, even if they didn’t lose any excess weight. Those who improved their fitness levels saw a 40% reduction.
Body-mass index (BMI), a measurement that takes weight and height into account, was not associated with mortality. The results were published in the journal Circulation.
What is “fitness”
Fitness is a measure of Read more »

[Editor’s note: In recognition of American Diabetes Month, Harvard Health Publications is collaborating with MSN.com on its Stop Diabetes initiative. Today’s post, published on World Diabetes Day, is the first of several focusing on this all-too-common disorder.]
People tend to think of diabetes as a silent, painless condition. Don’t tell that to the millions of folks with diabetes-induced tingling toes or painful feet. This problem, called diabetic neuropathy, can range from merely aggravating to disabling or even life threatening. It’s something I have first-hand (or, more appropriately, first-foot) knowledge about.
High blood sugar, the hallmark of diabetes, injures nerves and blood vessels throughout the body. The first nerves to be affected tend to be the smallest ones furthest from the spinal cord—those that stretch to the toes and feet.
Diabetic neuropathy affects different people in different ways. I feel it as Read more »

There was a very controversial presentation made at a recent meeting of heart doctors in Canada. I’ve been stewing about what to say about it for a week.
The title speaks to its inflammation:
Fat, unfit, unmotivated: Cardiologist, heal thyself
The presenter that made the stir, pediatric cardiologist, and IronPerson, Dr. Brian McCrindle (Toronto) argued that overweight, unfit doctors are doing their patients a disservice. His bottom line: cardiologists are acting like the rest of Western society. They are not living a healthy lifestyle.
He made three major points. (in-depth coverage can be viewed here, on TheHeart.org)

Fear of the “freshman 15” weight gain is overrated, says one researcher who found that the average college student packs on only between about 2.5 and 3.5 pounds.
And it might not even be the college lifestyle that causes one’s backpack to become a little more snug. Rather, it’s part of the natural transition into adulthood. The typical freshman only gains about a half-pound more than a same-age person who didn’t go to college.
“Not only is there not a ‘freshman 15,’ there doesn’t appear to be even a ‘college 15’ for most students,” researchers said in a press release.
The researchers concluded that the myth of the freshman 15 may contribute to Read more »

I recently saw a teenage boy with headaches. His father, wringing his hands, said that the headaches had been present for two years; but that the child had never been evaluated for them. No imaging, no neurologist. No insurance, of course.
A family friend, another child, had been diagnosed with a brain tumor. The family of my patient was terrified. Where to turn? They were, reasonably, concerned about cost.
Contrast that with the woman I saw on state assistance. Read more »
