Finding Health, Keeping the Money: Needles in the Nation's Haystacks

David Katz, M.D. | Posted 10.13.2013 | Healthy Living
David Katz, M.D.

Subsidizing better choices in the grocery store is a lot less expensive than stays in the intensive care unit. We don't need to prevent very many cases of diabetes, heart disease or bariatric surgeries to save back the costs of incentives for nutritious foods, 10 times over.

Pediatric Obesity, Ping-Pong, and Puzzle Pieces

David Katz, M.D. | Posted 10.12.2013 | Healthy Living
David Katz, M.D.

The picture suggests, encouragingly, that widespread attention to the crisis of childhood obesity can make a difference, and is seemingly starting to do so -- for some of the kids in some of the places at least some of the time.

Why Dieting Must Die

David Katz, M.D. | Posted 10.05.2013 | Healthy Living
David Katz, M.D.

If you doubt that children are endangered by obesity and its metabolic complications, you simply haven't been paying attention. And so my simple assertion is that the neglect is the same in both cases: feeding yourself as your children starve, or dieting while your children get fat.

Fructose, Fruit, and Frittering

David Katz, M.D. | Posted 10.02.2013 | Healthy Living
David Katz, M.D.

Why does anyone need to make a case for eating fruit? We have cited the combination of "fruits and vegetables" as the cornerstone of healthful eating throughout the entire era of modern nutrition, and it has been so since before the advent of modern humans.

74th Birthday, 54 Miles

David Katz, M.D. | Posted 09.29.2013 | Healthy Living
David Katz, M.D.

A 54-mile bike ride to celebrate a 74th birthday is, indeed, very cool -- for many reasons. My father's lifelong devotion to physical activity is partly responsible for my own.

Digesting The Implications Of Breakfast

David Katz, M.D. | Posted 09.28.2013 | Healthy Living
David Katz, M.D.

Research about breakfast tends to divide the world into those who skip and those who don't. But deferring and skipping are not the same. Skipping despite hunger, and deferring for want of it, are not the same. And clearly all breakfasts are not created equal.

Estrogen and Evidence

David Katz, M.D. | Posted 09.22.2013 | Healthy Living
David Katz, M.D.

We are certainly not saying that every woman with a hysterectomy should take estrogen. Our argument is exactly against the oversimplification of one-size-fits-all approaches.

Lethal Placebo

David Katz, M.D. | Posted 09.18.2013 | Healthy Living
David Katz, M.D.

All forms of hormone replacement for all women at menopause was never right, but nor is NO forms of hormone replacement for NO women at menopause. There was always baby and bathwater here, and we have egregiously failed to distinguish between the two.

Fish Tales and Prostate Cancer

David Katz, M.D. | Posted 09.17.2013 | Healthy Living
David Katz, M.D.

Is it plausible that higher omega-3 intake increases prostate cancer risk, but decreases breast cancer risk? I suppose the subtleties of carcinogenesis might allow for it, but I find it very far-fetched; if it doesn't stretch the envelope of credibility to the tearing point, it sure comes close.

Bunk About Junk Food

David Katz, M.D. | Posted 09.11.2013 | Healthy Living
David Katz, M.D.

While I agree that we can benefit from choosing a better chip, I think it's flaky at best to suggest that junk food will ever be beneficial. It is, in fact, oxymoronic -- give or take the oxy. If a food is good for us, it isn't junk.

Being Human First

David Katz, M.D. | Posted 09.10.2013 | Healthy Living
David Katz, M.D.

I am by no means suggesting that every doctor, or members of any given profession, should all be humanities majors. But a general decline in our respect for and attention to the humanities may be at our collective peril.

Clinical Karma

David Katz, M.D. | Posted 09.07.2013 | Healthy Living
David Katz, M.D.

Having medical training is a great privilege, and the source of, at times, quite literal life and death power. With that power comes a grave responsibility -- but bearing that is a privilege as well. Medical training is not a product of good fortune, but of willful preparation.

Fructose and the Follies of History

David Katz, M.D. | Posted 09.06.2013 | Healthy Living
David Katz, M.D.

A fixation on any nutrient property in isolation is a gilded invitation to the food industry to give us a whole new parade of products boasting that attribute, no matter what else might be in the mix.

Fast Food Fantasy

David Katz, M.D. | Posted 08.31.2013 | Healthy Living
David Katz, M.D.

Imagine if we -- the food customers -- rallied around a higher standard to serve our collective satisfaction. Could we really stand up to Big Food? Would we be biting off more than we could hope to chew and swallow, or might we really change the food supply?

Is It Wrong to Market Even Healthy Food to Kids?

Bettina Elias Siegel | Posted 08.26.2013 | Parents
Bettina Elias Siegel

No amount of legislation could entirely insulate children from food advertising in today's world, where even the inside of the bathroom stall is now considered fair game for marketers.

Just My Opinion

David Katz, M.D. | Posted 08.23.2013 | Healthy Living
David Katz, M.D.

In my opinion, science should not be treated like a ping pong ball. No one study replaces all that came before. Every study should be interpreted in context, situated into the prior body of accumulated understanding, because that's where studies make sense.

Obesity as Disease: Why I Vote No

David Katz, M.D. | Posted 08.21.2013 | Healthy Living
David Katz, M.D.

There is a certain irony in the nearly immediate juxtaposition of the rare introduction of a new FDA-approved drug for weight loss (Belviq) to the marketplace and the recognition of obesity as a "disease" by the AMA. A line from the movie Jerry Maguire comes to mind: "You complete me!"

Fantaspirations and Fallen Arches

David Katz, M.D. | Posted 08.17.2013 | Healthy Living
David Katz, M.D.

There are, I think, two dilemmas that complicate the reconciliation of wanting what we have and having what we want. Let's refer to them as the "night on call" conundrum, and the "wrinkle in time" fallacy.

Unity, Balance, and Power

David Katz, M.D. | Posted 08.12.2013 | Healthy Living
David Katz, M.D.

The notion that parasites are ravaging populations -- and clearly, they are -- is hard to reconcile with the already-impressive and fast-accumulating evidence that the aftermath of eradicating parasites is ravaging other populations.

Health Sucks

David Katz, M.D. | Posted 08.07.2013 | Healthy Living
David Katz, M.D.

We could manage our weight and our health with at least as great and reliable a ROI as we can get by managing our money. We could eliminate 80 percent of our lifetime risk of chronic disease. The grim landscape of modern epidemiology is not for want of knowing -- it's for want of doing.

The PRH (Personal Responsibility for Health) Chronicles, Part 6: Culture, Power, and Responsibility

David Katz, M.D. | Posted 08.03.2013 | Healthy Living
David Katz, M.D.

If you know it's important to control your weight and attend to your health, but almost everything in your environment and your culture conspires against such efforts -- how responsible are you, personally?

CoQ & A

David Katz, M.D. | Posted 07.31.2013 | Healthy Living
David Katz, M.D.

The current study, which thus far has only been presented at a conference, albeit a prestigious one, and not yet published in full in the peer-reviewed literature, appears to be a game-changer.

Diet, Dreams, and Nightmares

David Katz, M.D. | Posted 07.28.2013 | Healthy Living
David Katz, M.D.

In the process of creating ONQI 2.0, we are obligated to look at how the algorithm handles every food, including all of the quirkiest foods. In doing so, I wind up learning all of the intimate details about foods I could not otherwise have cooked up in my nightmares.

Let's Move More Than Our Lips!

David Katz, M.D. | Posted 07.24.2013 | Healthy Living
David Katz, M.D.

This time, let's prove we aren't all talk and no action. This time, let's demonstrate we aren't hypocrites. This time, let's prove we really are a nation of loving parents and grandparents, concerned and responsible adults. This time, let's move more than our lips.

Fixing Obesity

David Katz, M.D. | Posted 07.17.2013 | Healthy Living
David Katz, M.D.

As a culture, we are drowning in calories of mostly very dubious quality, and drowning in an excess of labor-saving technology. I have compared obesity to drowning before, but want to dive more deeply today into the implications for fixing what ails us.
