Most people who have lost weight understand how easy it is to gain it back. In fact, I often hear patients tell me that over the course of their lifetimes they’ve “tried every popular diet out there” and yet have failed to keep the weight off permanently. If that’s your situation, you’re not alone. It’s estimated that only 20% of overweight individuals are successful at long term weight loss. But there is hope for success, and we can learn the secrets of “successful losers” from the National Weight Control Registry.
In a flash of brilliance, sociologist Rina Wing and psychologist Jim Hill decided to create a database of weight loss success cases, and simply observe how they live their lives over decades of time. They called this research study the National Weight Control Registry, and it has been enrolling study subjects since 1994. What they’ve found is that those who have been successful at losing at least 30 pounds and keeping that weight off for at least 1 year share many behaviors in common. I believe that the closer we follow in the footsteps of these successful people, the more likely we are to be fit for a lifetime. So here goes – this is what the study subjects report: Read more »

The discovery of various vitamins – essential micronutrients that cause disease when deficient – was one of the great advances of modern scientific medicine. This knowledge also led to several highly successful public health campaigns, such as vitamin-D supplementation to prevent rickets.
Today vitamins have a deserved reputation for being an important part of overall health. However, their reputation has gone beyond the science and taken on almost mythical proportions. Perhaps it is due to aggressive marketing from the supplement industry, perhaps recent generations have grown up being told by their parents thousands of times how important it is to take their vitamins, or eat vitamin-rich food. Culture also plays a role – Popeye eating spinach to make himself super strong is an example this pervasive message.
Regardless of the cause, the general feeling is that vitamins Read more »

I’m proud to have been selected as the national, nutrition (“mind”) coach for the Boys & Girls Clubs’ Triple Play Fit Family Challenge. This is a 6-week challenge – five families (you can meet the families on the Fit Family Challenge blog) will compete for a grand prize: an all-expenses-paid vacation!
My job is to support the families with evidence-based nutritional information that they can use to establish lifelong healthy eating patterns. Proper nutrition is one of the most critical components of preventive medicine, and can help to reduce the risk for America’s top 3 killer diseases: heart disease, cancer, and stroke (not to mention type 2 diabetes, osteoporosis, and high blood pressure). If these families help their kids to adopt healthy lifestyles now, they will have a lower lifetime risk of many major diseases. And I hope that the kids will also become evangelists for healthy eating to their peers!
I’ve been thinking a lot about what I’ve learned over the years as a nutrition journal editor, avid foodie, and rehab physician, and I think that (to begin) I can truly boil down all we know about American eating habits into these three pieces of advice (note that these are based on HHS’s Dietary Guidelines For Americans, 2010): Read more »

Last week I wrote a simple post on eating yogurt with fresh fruit for lunch. It wasn’t until later that I realized why it’s a medical lesson.
It happens that yesterday morning I was up and out early. I saw a former colleague walking along the street. He’d gained weight, and walked slowly. I thought about how hard he works, and what a good doctor I know him to be. And yet any citizen or patient might size him up as heavy, maybe even unhealthy.
The problem is not that he’s uneducated or can’t afford nutritious foods. He knows fully about the health benefits of losing weight and exercise. The problem is the stress and long hours of a busy, conscientious physician’s lifestyle.
When I worked as a practicing doctor and researcher at the hospital, I rarely ate a nutritious breakfast or lunch. My morning meal, too often, consisted of Read more »

Here on SBM we have frequently had cause to criticize the media for poor science reporting and for spreading misinformation. Among many other individual offenders, we have criticized Dr. Oz for promoting alternative medicine on his TV show and gullibly promoting guests who pretend to talk to the dead and pretend to heal people with carnival sideshow tricks. We tend to be negative and critical because somebody has to do it, but it’s not pleasant. For once, I have some good things to say.
The September 12 issue of TIME magazine was a Special Nutrition Issue. The cover featured pictures of food and the title “What to Eat Now: Uncovering the Myths about Food by Dr. Oz.” It devotes 7 pages to an article by him entitled “The Oz Diet: No more myths. No more fads. What you should eat — and why.” This is followed by a 5 page article by John Cloud “Nutrition in a Pill? I took 3000 supplements over five months. Here’s what happened.” Both articles have a rational, science-based perspective without any intrusions of woo-woo.
Oz on What to Eat
Oz acknowledges that the science of nutrition is not simple and that much of what we once believed has been discarded in the face of new knowledge. He debunks a number of popular misconceptions about diet. Most of what he says is consistent with scientific evidence and with mainstream diet advice. Read more »
