If you have trouble finding the motivation to break away from the television and exercise, try couchersizing—staying on or near your couch and exercising during commercial breaks. Why bother? A growing body of evidence links the amount of time spent sitting to illness and even death. And just minimizing long periods of inactivity, like exercising during commercial breaks, can help reduce the risk of injury and may even help you live longer. You can work many different muscle groups while seated upright on a couch. Want to get your heart rate up, work the oblique muscles on the sides of the abdomen. To whittle your waist, try twisting your torso from side to side for the length of a commercial break. You can even exercise while lying on the couch.

Overeating during the holidays is practically a tradition. But overindulging can lead to weight gain, fatigue, and guilt. There are several tactical strategies you can employ to get you through the season of eating. Plan ahead: Find out when you’ll be eating, and plan your day around the meal; if you can bring a dish for the buffet, bring something healthy. At the buffet: Grab a salad plate instead of a dinner plate, and choose wisely; don’t waste calories on foods that aren’t special. At the table: Pace yourself by taking small bites, chewing slowly, and sipping water in between bites. Slowing down helps your brain get the message that you’re full. If all else fails: Don’t beat yourself up. Just get back to a healthy eating plan as soon as possible.
It’s been a big year for the Mediterranean diet. Convincing evidence published in 2013 has shown that this kind of eating pattern is effective at warding off heart attack, stroke, and premature death. While you probably get the biggest payoff by adopting such a diet early in life, a new study shows that doing it during midlife is good, too. In the study, women who followed a healthy diet during middle age were about 40% more likely to live past the age of 70 without chronic illness and without physical or mental problems than those with less-healthy diets. The healthiest women were those who ate more plant foods, whole grains, and fish; ate less red and processed meats; and had limited alcohol intake. That’s typical of a Mediterranean-type diet, which is also rich in olive oil and nuts.
A slowdown in the output of the thyroid gland can cause many problems, ranging from extreme fatigue and depression to intolerance to cold, weight gain, dry skin, and dry hair. Millions of Americans have an underactive thyroid, a condition known as hypothyroidism. The symptoms can usually be controlled with a daily dose of synthetic thyroid hormone called levothyroxine. Who actually benefits from taking levothyroxine is being called into question. New evidence suggests that many people with borderline hypothyroidism may be taking this medication unnecessarily.
The hottest trend in mobility right now is not a smart phone or wireless gadget. The mobility that’s making health headlines is the kind that let us do what we need to do: walk and move. Mobility is essential for getting through the day, whether you need to walk across a room to the bathroom or kitchen, get out of bed or a chair, or walk through a grocery store. Loss of mobility, which is common among older adults, has profound social, psychological, and physical consequences. The cascade of negative effects that comes with immobility can often be prevented or limited. Two questions can help determine if someone is having mobility issues.
There are many reasons to keep your blood sugar under control: protecting your arteries and nerves are two of them. Here’s another biggie: preventing dementia, the loss of memory and thinking skills that afflicts millions of older Americans. A study published today in the New England Journal of Medicine shows that even in people without diabetes, above normal blood sugar is associated with an increased risk of developing dementia. The study does not prove that high blood sugar causes dementia, only that there is an association between the two. For that reason, don’t start trying to lower your blood sugar simply to preserve your thinking skills, cautions Dr. Nathan. There’s no evidence that strategy will work, although he says it should be studied. But it is still worth keeping an eye on your blood sugar. Excess blood sugar can lead to diabetes and a variety of other health problems, including heart, eye, kidney, and nerve disease.
Do-it-yourselfers, take heart. Here’s something else to do at home that can have a substantial benefit on your health: measure your blood pressure. It’s easy, inexpensive, and helps control blood pressure better than visits to the doctor. The latest evidence for the benefits of home blood pressure monitoring comes from researchers in Minnesota. In a 12-month clinical trial, 72% of those doing home monitoring had their blood pressure under control compared to 57% who received usual care. The benefits persisted six months after the program had ended. Anyone can monitor blood pressure at home. You can buy a good home blood pressure monitor at a pharmacy or online merchant for anywhere from $50 to $100. Some insurance companies cover the cost.
The Mediterranean diet has been getting a lot of press as being the very best for health. But there’s another diet that appears to be equally good: a vegetarian diet. A study published in JAMA Internal Medicine found that people who ate a vegetarian diet were 12% less likely to have died over the course of the five-year study than nonvegetarians. The benefits were especially good for men, who had a significant reduction in heart disease. This study underscores the idea that meat consumption influences long-term health, and not in a good way. Should you consider ditching the Mediterranean diet and becoming a vegetarian instead? Either one is healthier than the typical American diet, so it’s really a matter of personal choice.
Adding more protein to the diet and cutting back on carbohydrates, especially highly processed carbs, is an eating strategy adopted by a growing number of people. A new study in the Journal of Nutrition Education and Behavior found that 43% of women surveyed are using the practice of eating more protein to prevent weight gain, and this strategy was associated with weight loss. It isn’t necessary to eliminate all carbohydrates and focus only on protein. Such an eating strategy may have a short-term payoff for weight loss, but it may also come with some long-term risks. Tips for getting a healthful mix of nutrients include adding the healthful trio of fat, fiber, and protein to each meal; avoiding highly processed foods; and choosing the most healthful sources of protein, such as fish, poultry, eggs, beans, legumes, nuts, tofu, and low-fat or non-fat dairy products.
Physical and mental activities are both important for protecting your thinking skills and warding off dementia. But does one trump the other? A study published yesterday in JAMA Internal Medicine tried to tease out if one was better than the other for brain health. Researchers recruited 126 older adults who felt that their memory or thinking skills had recently gotten worse, and divided them into four groups. All were asked to do an hour of mental activity three times a week and an hour of physical activity three times a week. What differed were the intensities of these activities. After 12 weeks, scores on thinking tests improved across the board. The big surprise was that there weren’t any real differences in improvement between the groups. The researchers concluded that the amount of activity is more important for stimulating the brain than the type of activity, because all of the participants both exercised and engaged in mental activities each week.
