Diet and Weight Loss
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.
New Jersey Governor Chris Christie’s revelation yesterday that he had secretly undergone weight-loss surgery back in February shouldn’t come as a big surprise. He has been publicly (and privately) struggling with his weight for years and fits the profile of a good candidate for this kind of operation. In general, weight-loss surgery is appropriate for people with a body mass index (BMI) of 40 or higher, as well as for those with a BMI of 35 to 39.9 and a severe, treatment-resistant medical condition such as diabetes, heart disease, and sleep apnea, who had tried to lose weight other ways. Christie had a BMI of at least 41. He also acknowledged trying to lose weight many times, using different weight loss programs. He underwent laparoscopic gastric banding, also known as lap banding. There are also two other types of weight-loss surgery, gastric bypass and the gastric sleeve procedure.
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.
When you decide it’s time to live a healthier lifestyle, you’re likely to get better long-term results if you start improving your diet and increasing physical activity at the same time. It may seem better to improve just one thing at a time. But while you don’t have to make drastic changes overnight, a new […]
If you are worried about your weight, paying more attention to what you eat, not less, could help keep you from overeating. Multitasking—like eating while watching television or working—and distracted or hurried eating can prompt you to eat more. Slowing down and savoring your food can help you control your intake. That’s the bottom line from a report published in the April issue of the American Journal of Clinical Nutrition. It offers two key conclusions: 1) Being distracted or not paying attention to a meal tended to make people eat more at that meal. 2) Paying attention to a meal was linked to eating less later on. Mindful eating is a good solution. It can reduce daily calorie intake, help make healthier food choices, and add to the enjoyment of eating.
Type 2 diabetes doesn’t usually appear all of a sudden. Many people have a long, slow, invisible lead-in to it called prediabetes. During this period, blood sugar levels are higher than normal. However, they’re not high enough to cause symptoms or to be classified as diabetes. It’s still possible at this stage to prevent the slide into full-blown diabetes. Think of prediabetes as a wake-up call. Unfortunately, few people ever hear the alarm. A new report from the Centers for Disease Control and Prevention shows that among Americans age 20 and older, only 10% of those with prediabetes know they have it. Given that as many as 73 million Americans have prediabetes, that’s a lot of missed opportunities to prevent the ravages of diabetes. One reason many people don’t know that they may be headed toward diabetes is they’ve never had their blood sugar tested. This simple test isn’t part of routine preventive care, but perhaps it should be.
It’s easy to get swept up in the holiday season. This combination of religious and national celebrations can help keep the cold winter away. But the feasts and parties that mark it can tax the arteries and strain the waistline. By eating just 200 extra calories a day — a piece of pecan pie and a tumbler of eggnog here, a couple latkes and some butter cookies there — you could pack on two to three pounds over this five- to six-week period. That doesn’t sound like much, except few people shed that extra weight in the following months and years. You don’t need to deprive yourself, eat only boring foods, or take your treats with a side order of guilt. Instead, by practicing a bit of defensive eating and cooking, you can come through the holidays without making “go on a diet” one of your New Year’s resolutions.
Do you have trouble sleeping? If you’re carrying extra pounds, especially around your belly, losing weight and some of that muffin top may help you get better ZZZs. So say researchers from Johns Hopkins University School of Medicine, who presented their findings at this year’s annual meeting of the American Heart Association. In a six-month trial that included 77 overweight volunteers, weight loss through diet plus exercise or diet alone improved sleep. A reduction in belly fat was the best predictor of improved sleep. Among people who are overweight, weight loss can reduce sleep apnea, a nighttime breathing problem that leads to frequent awakenings. Exercise has also been shown to improve sleep quality. Despite what thousands of websites want you to believe, there are no exercises or potions that “melt away” belly fat. Instead, the solution is old-fashioned exercise and a healthy diet.
Many medical studies confirm what we know or suspect. Every once in a while, though, one surprises us, turning “conventional wisdom” on its head. That just happened with the sudden shutdown of a long-running diabetes trial called Look AHEAD (Action for Health in Diabetes). Begun in 2001 and scheduled to last another two years, Look AHEAD was designed to see if an intensive diet and weight loss program could reduce the number of heart attacks, strokes, and other cardiovascular problems in people with type 2 diabetes. An early peek at the data showed that the program had little apparent effect, and the investigators concluded it would be futile to continue. This does not mean that we should ignore diet and exercise in treating of type 2 diabetes. Instead, the details of the study results, which haven’t yet been published, are likely to reveal other explanations.
We tend to think of type 2 diabetes as a disease that afflicts people who are overweight. But it can also appear in people with perfectly healthy weights—and be more deadly in them. A study published in the Journal of the American Medical Association indicates that normal-weight people diagnosed with type 2 diabetes have double the risk of dying from heart disease and other causes than overweight people with diabetes. Such apparent “protection” by excess weight has been called the obesity paradox. It’s been seen with other conditions, like heart failure and end-stage kidney disease. That doesn’t mean gaining weight is a healthy strategy. Instead, it probably means that something else besides weight—like the amount of fat around the waist—may be contributing to the onset and severity of type 2 diabetes. These new findings underscore the importance of strength training for everyone, no matter what their weight.
