Smoking is far worse for your health than obesity

Why are Americans more afraid of gaining weight than smoking cigarettes?

Which is a more serious problem for America, smoking or overeating? According to a Gallup poll released this week, 67 percent of the nation’s adults think of cigarettes as an “extremely serious” or “very serious” social problem, compared with 81 percent who say the same for obesity. Gallup first started asking this question in 2003, and now, for the first time, respondents have shown that they’re more worried about jiggly thighs than blackened lungs.

The idea seems to have made its way to Wall Street and Washington, too. Just this week, a group of equity strategists from Bank of America and Merrill Lynch proclaimed that “global obesity is a mega-investment theme for the next 25 years and beyond,” and the Food and Drug Administration approved a weight-loss drug for the second time in two months—having finally calmed its nerves after the deadly fen-phen scandal of the late 1990s.

The shift in public opinion suggests a dangerous and unintended consequence of the war on obesity. Years of epidemiological work have shown that smoking is far worse for your health than being fat. So much worse, in fact, that any suggestion to the contrary should be taken as a sign that our priorities are getting all mixed up.

Fat is correlated with ill health, of course, and the one-third of the U.S. population who qualify as obese may be subject to some very real and severe consequences. An obese person is up to twice as likely to die of any given cause than someone whose body mass index is in the normal range, controlling for other factors. In medical terms, we would say that his or her relative risk of all-cause mortality is between 1 and 2. What about smoking? The analogous number for those who consume at least one pack of cigarettes per day is 3.7, meaning that heavy smokers are almost four times more likely to perish than nonsmokers, about double the risk associated with obesity. Estimates of avoidable deaths reflect this difference in the odds: According to the U.S. Centers for Disease Control and Prevention, smoking accounts for an excess mortality of more than 400,000 Americans every year, compared to just 112,000 for obesity. That’s despite the fact that there are many more fat Americans—obesity rates are now 50 percent higher than smoking rates.

These numbers are just for the extremes. Even at the shallow end of the pool, smokers are at greater risk. If we limit the analysis to light tobacco users—those who consume a handful of cigarettes per day—then the relative risk of mortality turns up at 1.5, roughly the same as it would be for people with full-blown obesity. What about the folks who aren’t huge but merely overweight? CDC research suggests they have a relative risk of less than 1, in which case carrying a bit of extra weight could even provide some kind of protective effect on your health.

Yet this disparity in outcomes has become ever harder for the public to grasp. The intensifying rhetoric about obesity—from the White House, from HBO, from Michael Bloomberg—has obscured some truisms of the war on smoking. The Gallup poll tells us that Americans are 20 percent more likely to label obesity as a grave social problem, a national misconception that’s only made more dispiriting by recent news on the tendency of those who quit smoking to gain weight. For a paper published last week, researchers in France and England reviewed the data from more than 60 studies of this effect. It’s long been known that tobacco keeps you thin: Nicotine increases metabolism while suppressing appetite. But these factors have a greater effect than was previously thought. In the year after people quit smoking cigarettes, they gain about 10 pounds on average.

How might this affect smoking rates? Earlier work has shown that concerns over weight gain do indeed hamper efforts to quit. A study of women who stopped smoking cigarettes when they became pregnant found that two-thirds relapsed within six months of giving birth, with the ones who were most worried about getting fat being the most at risk. Another survey showed that women who quit smoking ended up feeling worse about their bodies, on average, than they did before—an effect that almost certainly increases their odds of falling off the wagon. (Poor body image is itself a major risk factor for smoking.)

It’s telling that the prospect of gaining a few pounds can lead to the resumption of such a deadly behavior. The marginal health risk of this shift on the BMI scales is slight or nonexistent, but the social stigma is more severe. That’s why spurious weight concerns are among the most common reasons why women quit using birth-control pills and put themselves at risk for unwanted pregnancies and all the complications (including weight gain) that come with it. Discrimination against fat people has real effects, too, in terms of income, quality of health care, relationship status, and even rates of heart disease and diabetes.

Some of the respondents in the Gallup poll may be well aware that smoking is the deadlier problem. It’s possible they’re more concerned about obesity than smoking because they know that smoking rates have dropped in recent decades, while obesity rates are increasing or at best leveling off. But if we could reduce the number of smokers by another five or 10 percentage points, it might yield the same net improvement for public health as the invention of a magic pill that could turn every fat person thin.

It’s remarkable, when you think about it, that the war on smoking has been as successful as it has been, considering all the superficial excuses there are to maintain the habit. Nicotine is addictive in a way that food, as a category, isn’t. Smoking is less shameful for most people than overeating, and it keeps you thin. There’s evidence that it prevents teenagers from getting acne—one recent study found a dose-dependent, inverse relationship with cigarette consumption among a sample of 27,000 soldiers in the Israeli army—and that men who quit smoking experience rapid drops in testosterone. In other words (as we all suspected) tobacco use can improve your social status.

The fact that we’ve managed to cut smoking rates in spite of these factors doesn’t make tobacco any less of a scourge, or obesity any more dangerous in comparison. If anything, the paradox suggests that stigma is not in itself a solution to social ills. If Americans are more worried about obesity than smoking, it’s because they’ve let the shame of being fat cloud their judgment with second-hand smoke.

The Simple Trick that Strengthens Your Brain

This excellent article really explains how science is discovering that meditation can have huge positive effect on the health of your brain.

The Simple Trick That Strengthens Your Brain

By Isaac Eliaz, MD, integrative health expert

Meditating actually improves the structure of your brain.

As a holistic physician and meditation practitioner with more than 25 years of experience, I have always believed strongly in the mental and emotional benefits of regular mindful meditation practice.

The practice of regular meditation has been found to increase brain density, boost the connections between neurons, decrease the symptoms of depression and anxiety, provide clarity of thought, and increase positive mood endorphins. Other published studies have shown that meditation can improve physical functioning, decrease chronic disease risks, and enhance overall quality of life.

These studies demonstrate that regular meditation effectively supports mental, emotional, and physical health in numerous tangible ways. In building upon this strong body of evidence, researchers are continuing to deepen our understanding of the profound and inspiring benefits of regular meditation practice in everyday life.

6 Surprising Benefits of Meditation

Meditation literally changes your brain
Most recently, neuroscientists at UCLA have shown another fascinating neural effect of regular meditation: improvement of the brain’s ability to process information quickly. Meditation actually causes the cerebral cortex—the layer of neural tissue that serves an important role in controlling memory, consciousness, thought processing, decision-making, attention, and awareness—to fold, creating indented fissures and creases that increase neural processing and neurotransmitter communication. The technical term for this is “cortical folding.”

The neuroscientists at UCLA compared meditators of different experience levels to people who never meditated. In those who meditated, the scientists found significant increases in cortical folding across a wide area of the brain, and not just in the cortex. They saw changes in areas of the brain responsible for emotional and mental health, influencing processes of emotional control and heightening awareness and introspection. This falls directly in line with some of the more noticeable results of regular meditation, which often include increased compassion for one’s self and others and greater emotional stability.

Your body benefits, too
Meditation’s physical payoffs are equally impressive. We all know that reducing stress can dramatically improve health on a number of levels. The proven beneficial effects of regular mindful meditation are protection against and reversal of DNA damage, a boost in immune function, reduction of cardiovascular disease risks, decreased inflammation, improved outcomes in cancer, reduced side effects of conventional treatment, and increased vital energy and physical capacity.

As regular meditation practice becomes better understood and more widely practiced, more and more doctors and health practitioners are recommending these ancient disciplines to their patients. If you are looking for some extra healing energy to improve your health, regular meditation can provide just the solution.

Soothe Chronic Pain—Meditate

——————————————————————————–

Want to get started?
Meditation is most effective when practiced regularly. Just 10 minutes a day can offer significant and noticeable benefits over a short period of time.

While there are countless styles of meditation practice, one of the most profound is the ancient Tibetan practice of Shamatha Meditation (shamatha means “calm abiding” in Sanskrit). It’s intended to help people access their mind’s natural state of tranquility and clarity. The technique involves focusing the breath on a specific object, letting go of all other thoughts, and consistently training the attention on the process of breathing.

Find a quiet, comfortable place to sit, and pick a small object such as a rock to place on the ground in front of you. Focus your eyes and your breathing on the rock, and as thoughts inevitably arise, simply acknowledge and then release them, letting them slip away with each outward breath. When your mind wanders off, gently bring your attention back to your breathing and the rock, visualizing each inhalation and exhalation going to and from the rock.

As you become more practiced at meditation, you will likely notice significant improvements in your energy, health, and mental/emotional balance. You may find that as distractions and obscurities are peeled away during mindful meditation practice, the space between thoughts becomes greater and more profound. As we slowly turn down the constant chatter of our minds, we can begin to access deeper aspects of consciousness for growth and healing.

To me, one of the most beautiful and profound aspects of meditation is that this process of growth and unfolding (figuratively and literally) can continue throughout our lives. After all, we can never have too much love, compassion, and clarity.
