Intermittent Fasting for Weight Loss, a Bad Idea
March 5th, 2013 at 4:47 pm by timigustafsonA new diet has become all the rage in Britain and is now making landfall on our shores as well. It’s called the “Fast Diet” and millions of weight loss candidates already swear by it.
Like all commercial diet programs, this one promises quick results without much effort and little changes in established eating habits. Followers can eat anything they want for five days but then have to undergo a fasting period of 48 hours where they cannot consume more than 500 to 600 calories per day.
The authors, Dr. Michael Mosley, a medical journalist, and Mini Spencer, a food and fashion writer, claim they both have experienced amazing weight loss successes themselves while experimenting with various forms of intermittent fasting. They also believe their approach can promote overall health and even longevity.
The idea of submitting oneself to periods of food deprivation is nothing new, of course. Our hunter-gatherer ancestors did it, although perhaps not voluntarily, and many religions recommend it as a ritual for cleansing, both physically and spiritually.
“Voluntarily abstaining from eating for short periods of time will allow you to eat what you like, most of the time, and get slimmer and healthier as you go,” the authors proclaim on their website. “The joy of the Fast Diet is that the side-effects are all good,” they say.
But are they?
Even if its true that our bodies are genetically programmed to endure periods of famine, as our forbearers were forced to with regularity when food supplies ran scarce, that doesn’t mean it is a good idea to disrupt your metabolism every so often just to shed a few extra pounds in a hurry.
For example, when the body is subjected to severe calorie restriction, it goes into a different metabolic mode where it switches from burning carbohydrates (glucose), its preferred fuel, to burning fat. This may at first sound like a good idea since body fat is what dieters want to get rid off. However, if this process continues for too long, it can lead to a state known as ketosis.
When fat stores become the primary source for fuel, weight loss will occur – but not without side effects. During ketosis, the body builds up substances known as ketones, which can cause a number of health problems. Loss of appetite, nausea, dizziness, irritability, tiredness and bad breath are among the milder symptoms. More serious consequences include dehydration, gout, kidney stones and even kidney failure.
For healthy individuals, short-term ketosis may not carry serious risks. However for diabetics, restricting carbohydrates in their diet may give rise to complications. In extreme cases, ketone levels can become so elevated that a situation develops where high blood sugar is met with a severe shortage of insulin. This is known as diabetic ketoacidosis (DKA). The results, if not immediately treated, can be fatal.
Many followers of weight loss diets are plagued with one or more of these conditions. Experimenting with one’s metabolism, especially when done without supervision by a medical professional, can only make matters worse.
Last but not least, there are the long-term implications to be considered. Are we to believe that a five-day period of no dietary restrictions followed by two days of disciplined fasting is a viable option for most people? It seems to me such a regimen bears a strong resemblance to many of the crash diets that may produce quick results but inevitably fail over time.
In response to this latest diet craze, Britain’s National Health System has posted a warning on its website that says: “Despite its increasing popularity, there is a great deal of uncertainty about IF (intermittent fasting) with significant gaps in the evidence.”

Can Marital Bliss Make Us Healthier? (Emphasis on Bliss)
December 5th, 2012 at 12:36 pm by timigustafsonDo married people live longer, healthier lives than their single counterparts? This is not an issue that came up only recently, e.g. in connection with the increasing acceptance and legalization of same sex marriage or statistics that show unmarried people outnumbering married ones for the first time in America’s history. In fact, as far back as in the mid 1800s, scientists have investigated the potential benefits of marriage, not only in terms of economics and social status but specifically for health.
A British epidemiologist named William Farr was one of the first to study what he called “conjugal condition,” by which he meant the impact of marital status on people’s health. He found that married couples had on average longer life expectancies than the unmarried or the widowed. His findings, although now outdated in methodology and scope, still hold and have been confirmed by multiple studies on the subject that is known as the “marriage advantage”.
Obviously, it would be a mistake to credit marriage itself as the sole source of such benefits. Back in William Farr’s days, as today, it is tempting to exaggerate the importance of the institution while underestimating the difference that quality and character of a marriage makes, says Tara Parker-Pope, a health writer for the New York Times/Well blog. “The mere fact of being married, it seems, isn’t enough to protect your health,” she says.
In fact, clinical studies have found that being in stressful relationships or marriages can lead to serious health problems, including heart disease. In other words, you can actually die of a broken heart, quite literally.
Marital distress can be a chronic stressor, concluded one study that focused on couples facing problems early on in their marriages. Among other effects, some spouses showed “poorer immunological responses,” meaning their immune system weakened, leaving them less protected against any number of diseases.
And it doesn’t have to come to open conflict to diminish the advantages that may or may not come after tying the knot. No matter how happy and excited couples are at the outset, wedded bliss has a limited shelf life, writes Sonja Lyubomirsky, a professor of psychology at the University of California, Riverside, in a recent op-ed article on the issue in the New York Times. “New love seems nearly as vulnerable […] as a new job, a new home, a new coat and other novel sources of pleasure and well-being,” she says. “The special joy wears off and [newlyweds] are back where they started, at least in terms of happiness.”
So, is there any chance for lasting marital bliss with all its promises? There can be, according to Dr. Lyubomirsky, if couples stick it out and get over the hurdles that inevitable come when reality sets in. What sometimes happens is that spouses rediscover each other once the kids are grown and out of the house. So-called empty-nesters have a chance to fall in love all over again, but this time on more solid ground and with fewer expectations. That can be healthier and still enhance their overall well-being.
Of course, there are no specific rules how to keep the proverbial fires going or rekindle them if necessary. What often goes missing as marriages endure is an element of surprise and variety, says Dr. Lyubomirsky. Eventually routines dominate our lifestyles and we settle for the status quo. We know who we are and think we know all there is to know about our partners. While familiarity does not necessarily breed contempt, it certainly can foster a growing degree of indifference.
This is where couples can and should become creative and engage in activities both partners enjoy to bring back a bit of excitement into their lives. The curiosity and keen interest in each other they once had when love was young does not have to be lost. On the contrary. Some say, those who play together, stay together. So, let’s explore…

Enhancing the Quality of Life Wherever We Can
October 31st, 2012 at 12:45 pm by timigustafsonFor the longest time, there has been nothing but bad news coming from Greece: An economy in complete shambles, high unemployment, drastic tax hikes and cutbacks in social services, unrest in the streets, a society at the brink of collapse. And yet it is precisely in this region where people seem to live longer, healthier lives than about anywhere else on the planet. What’s their secret?
Based on years of research, Dan Buettner, best-selling author of “The Blue Zones: Lessons in Living Longer from the People Who’ve Lived the Longest” (National Geographic Society, 2008), and two of his colleagues found that the inhabitants of the Greek island of Ikaria were reaching the age of 90 at two and a half times the rate Americans do.
“Ikarian men in particular are nearly four times as likely as their American counterparts to reach 90, often in better health. But more than that, they were also living about 8 to 10 years longer before succumbing to cancers and cardiovascular disease, and they suffered less depression and about a quarter the rate of dementia.” By contrast, Buettner says, almost half of American seniors show signs of Alzheimer’s by the age of 85.
Despite of its remoteness and rugged, mountainous landscape, the island has been known for centuries for its health-promoting climate and soothing hot springs. A slow-pace, leisurely lifestyle is still prevalent among the people here who savor tasty meals and long afternoon naps. Time seems to stand still – most villagers don’t even wear watches.
Many of the young people who once left the island in search of better paying jobs in the cities have returned, disillusioned with their fading prospects. Because of high unemployment rates, some have no choice but to move back in with parents and grandparents, but others see the lifestyle of their forbearers as a viable alternative.
Besides tourism, small-scale agriculture is the only industry on Ikaria. When it comes to food supply, most families are self-sufficient. Gardening and tending to livestock fills the day that starts late in the morning and ends with dining and socializing with family, neighbors and friends.
The latter is as crucial as the diet the Ikarians adhere to. The social structures might turn out to be even more important, says Buettner. The cultural attitude that honors and celebrates old age keeps seniors more engaged in their communities. Studies have shown that the concept of retirement, common in industrialized countries, actually reduces life expectancy. Such “artificial punctuations” in life, as he calls it, deprive retirees unnecessarily of a sense of purpose and meaningful existence.
Another puzzling phenomenon is that Ikarians also live longer than other islanders in the region who share a comparable environment. Obviously it’s not one specific thing that sets these people apart, says Buettner, but rather a host of “subtly powerful, mutually enhancing and pervasive factors are at work” such as a healthy diet, sufficient sleep, lack of stress and time pressure, daily physical activity through walking and manual labor, and being part of a functional community. In other words, it’s the high quality of life that results in the extraordinary longevity.
Obviously, not everyone can move to an idyllic island and grow vegetables, milk goats, bake bread and snooze the afternoon away. But what we all can do is to stop once in a while and consider whether our days really have to be as hectic and exhausting as they often are. Perhaps we would be better off if we took regularly inventory and separated what’s necessary from what just crept in on us.
We don’t have to aim at living forever. Longevity itself doesn’t have to be the primary goal. Being around a few years longer is not worth the effort if we’re only getting more of the same. A better quality of life, on the other hand, is something we can always strive for at any time and anywhere.

The New Great Divide: Longevity
September 26th, 2012 at 1:08 pm by timigustafsonThe United States of America have often been called a divided nation, separated by race, class, political affiliation, values, you name it. Now, one study has found that we are also drifting apart in terms of life expectancy. While the better-off can hope to live longer than ever, the rest falls behind and may even die at a younger age than their parents.
Educated white males seem to have the edge on longevity. Conversely, the least educated and often poorest Americans, regardless of gender or race, are moving in the opposite direction. The average life expectancy for them has fallen by four years since 1990.
The disparities are most dramatic between highly educated white men and the least educated black men, about 14 years, according to Dr. S. Jay Olshansky, a professor of epidemiology at the University of Illinois at Chicago School of Public Health and lead author of the study report.
These widening gaps within our society have lead to “at least two Americas, if not multiple others, in terms of life expectancy, demarcated by level of education and racial-group membership,” said Dr. Olshansky.
The causes behind these trends are not altogether clear, although unhealthy lifestyles like alcohol and drug abuse, smoking, poor diets, obesity and lack of health care coverage are among the most likely factors.
A separate study predicts that obesity, along with multiple related diseases, will continue to rise across the nation, but especially in states with the poorest populations. The report, sponsored by Trust for America’s Health (TFAH) and the Robert Wood Johnson Foundation (RWJF), concluded that the numbers of diet and lifestyle-related illnesses could increase tenfold by 2020 and double again by 2030.
Currently, more than 25 million Americans suffer from diabetes, 27 million from chronic heart disease, 68 million from hypertension and 50 million have arthritis. Every year, almost 800,000 have a stroke, and about one in three deaths from cancer are related to weight problems, poor eating habits and physical inactivity.
While many Americans are becoming more health-conscious, the majority continues on a dismal path. “This study shows us two futures of America’s health,” said Dr. Risa Lavizzo, president and CEO of RWJF. “At every level of government, we must pursue policies that preserve health, prevent disease and reduce health care costs,” she said. “Nothing less is acceptable.”
Treating obesity and related diseases already costs an estimated $147 to $210 billion annually in health care, and these numbers will increase by another $48 to $66 billion if current trends persist, according to TFAH. The only way to change course is “to invest in obesity prevention programs that match the severity of the problem,” said Jeff Levi, TFAH’s executive director, at a news conference for the study release. The report included a series of policy recommendations such as swift implementation of existing legislation (e.g. the Healthy, Hunger-Free Kids Act) as well as creation of additional prevention strategies and action plans.
Government can definitely play an important role in the fight against the obesity epidemic, said Dr. Thomas A. Farley, Commissioner of the New York City Department of Health and Mental Hygiene. Government regulations are a justifiable option when they lead to preventing excess calorie consumption and obesity-related health problems and deaths, he wrote in an article for the Journal of the American Medical Association (JAMA).
In this country, we have long treated lifestyle choices as personal matters that should not be regulated or interfered with, even if they produce undesirable results. It’s a part of our individualistic culture. There is much to be said for that, but, as it is becoming increasingly apparent on so many levels, our attitudes have consequences, and sometimes they make the difference between life and death.

Living Long, Living Well
August 29th, 2012 at 5:47 pm by timigustafsonAmericans may be less optimistic about the future in general than they once were, but a solid majority still hopes to enjoy a long life. In fact, longevity is considered by most as part of a good life, on par with health, prosperity and loving relationships.
60 percent expect to live at least until they’re 80. 40 percent think 120 to 150 years could be feasible within their own lifetime due to further advancements in medical and biological technology. And one percent believes that death could eventually be eliminated altogether, according to a survey conducted by David Ewing Duncan, a science writer and author of “When I’m 164: The New Science of Radical Life Extension and What Happens If It Succeeds.”
Considering that two thirds of the population are currently dealing with weight problems and a host of lifestyle-related diseases, this may be wishful thinking for many. But the fact is that the average life expectancy has indeed dramatically increased over the last century due to improved hygiene, diet and medical care. In 1900, people could expect to live just under 50 years. In the year 2000, it was nearly 77. The average lifespan was lengthened between 1.5 and 2.7 years per decade, according to data collected by the U.S. Census Bureau.
What’s even more stunning is that our chances of living longer seem to go up all the time. How so? “Because the more time you spend in the world, the more time the world gives you,” says Ted C. Fishman, author of “Shock of Gray” (Scribner, 2010). “For every hour we live,” he claims, “the average human lifespan increases between eleven and fifteen minutes. Every day sees the average lifespan grow another five hours.”
Of course, that doesn’t apply for everyone across the globe, Fishman admits. “Your odds are better if you have avoided the obesity epidemic and live in a place that enjoys good health care, education, and freedom from war and terrible poverty.” It also helps if you can manage to stay mentally fit and don’t suffer from memory loss and cognitive decline. A loving family, a circle of friends and other supportive social surroundings add to your chances.
Unfortunately, many of these important factors for longevity cannot be taken for granted. Baby boomers, now entering retirement, are rightly worried about their prospects when it comes to their financial security, health needs and social life.
“It does not bode well for the baby boom generation at all,” warns Dr. S. Jay Olshansky, a professor for public health at the University of Illinois at Chicago who studies longevity, in an interview with Reuters. More recent studies show that life expectancy gains in the U.S. have actually flattened out since the 1960s. Despite of dramatically increasing expenditures for health care, many Americans live with chronic diseases that are left insufficiently treated, especially among the uninsured and those with limited coverage. One study concluded that poorer citizens have on average a shorter lifespan of up to five years than the more affluent.
Obviously, money can’t buy everything and life remains an uncertain enterprise no matter how rich you are. For the rest of us, there are plenty of opportunities to take care of our health and well-being by eating right, exercising, etc. (you know the drill) – and for this, it’s never too early to get started.
Researchers found that physical fitness achieved during middle-age can lower the risk of developing chronic diseases like diabetes, heart disease, high blood pressure in later years and may be associated with compression of morbidity at old age. Compression of morbidity is what many health experts consider the optimal outcome of aging. The idea is “to delay the onset of age-related disease and inevitable decline without worrying about extending life,” writes Dr. Andrew Weil, author of numerous best-selling health books, including “Healthy Aging” (Knopf, 2005). Not longevity itself should be our first concern, but the quality of life we have as long as we are around, he says.
This reminds me of the late Steve Jobs, the founder of Apple Inc. who died last year at the age of 56, when he spoke of the inevitability of death at his 2005 Stanford Commencement Address.
“No one wants to die,” he said. “Even people who want to go to heaven don’t want to die to get there. And yet death is the destination we all share. No one ever escaped it. And that is as it should be because Death is very likely the single best invention of Life. It is Life’s change agent. […] Your time is limited,” he ended, “so don’t waste it…”
Even the longest life can be a waste if it’s not brought to its full potential. Even the shortest life is rich and fulfilled if it’s lived well.

Following a Heart-Healthy Lifestyle Can Add Years to Your Life
March 25th, 2012 at 3:48 pm by timigustafsonDo you observe a healthy diet, abstain from smoking, watch your cholesterol, blood pressure, blood glucose levels and do you exercise at least for 30 minutes three times a week? If so, your chances of dying from a heart attack are much lower than those of your contemporaries with less health-promoting lifestyles.
Researchers found that taking a few simple, commonsense steps to protect your heart can reduce the risk of cardiovascular disease more substantially than previously thought.
For a recently completed study that followed almost 45,000 adult Americans, scientists looked into data collected by the U.S. National Health and Nutrition Examination Survey and linked them with a database of deaths over three time periods, starting in 1988 and ending in 2010. After almost 15 years of follow-up, the survey showed that participants who adhered most closely to the diet and lifestyle recommendations of the American Heart Health Association (AHA) had a 76 percent lower risk of dying from heart disease and a 51 percent lower risk of all-cause deaths than those who complied less. The details of the study were published in the Journal of the American Medical Association (JAMA – 3/23/2012).
Unfortunately, the researchers also found that only a small minority of Americans follows all or most of the AHA guidelines for heart health.
“Everyone knows that the heart health of Americans is dismal. Yet, despite of trying hard (really hard), I fail more than 90 percent of the time to get patients to change their heart-healthy behaviors,” laments Dr. John Mandrola, a cardiologist. “Nine in ten patients return just as fat and sedentary as they were at the time of my previous lecture on heart health.”
The problem is not that Americans lack access to information that prevents them from taking better care of their heart health. “Getting people to know [the facts] is not the issue, rather the issue is the implementation of the plan, says Dr. Mandrola.
Heart disease is the most common cause of deaths in the U.S. today, ahead of cancer and stroke. One and a half million Americans die every year from the disease or complications connected to it. While it is true that heart disease can be caused by inherent risk factors such as family history or simply by aging, poor lifestyle choices are to be blamed in most cases. Excess weight, diabetes, high cholesterol levels, high blood pressure, smoking, alcohol abuse and insufficient physical activity are all commonly known culprits. Most heart patients have several of these risk factors to deal with – and they tend to “gang up” and aggravate each other’s effects.
Heart disease usually shows no specific warning signs. You have to look at the numbers to find out about your heart’s health condition. “You can and should make a difference in your heart health by understanding and addressing your personal risks,” says Dr. Susan B. Shurin, director at the National Heart, Lung and Blood Institute of the National Institute of Health (NIH). For any successful treatment of heart disease as well as for prevention it is crucial to regularly monitor cholesterol levels – LDL (bad) cholesterol, HDL (good) cholesterol and triglycerides –blood pressure and, of course, body weight.
Americans tend to rely too quickly on medications when they encounter heart health problems. In many cases that may be a necessary first step, but the goal should always be to achieve risk reduction by better diet and lifestyle choices. “Good Nutrition and lifestyle are the cornerstones of health,” says Dr. Leslie Cho, director of the Women’s Cardiovascular Center at the Cleveland Clinic. “Pills are supplements. They’re not a substitute for a healthy lifestyle.”
