A new way of looking at what we eat

This is a really cool visualization of the “healthiness” of food people eat over a 24 hour time period. This visualization is based on data collected from over 7 million people over five months who track what they eat using an iPhone all called Eatery. Users upload a photo of their food and it is rated by others. While the people doing the rating aren’t nutrition experts, the results are still useful. This is a concept called crowd sourcing. It turns out that feedback from multiple non-experts can approximate what you would learn from one expert. In a sense, the crowd becomes the expert. Consider the jelly bean example: one of the most accurate ways to guess the number of jellybeans in a jar is to average the guesses of everyone in the room.

Back to the visualization…Notice that people tend to eat less healthy food at night. While much of this has to do with choices we make when we are up late, it may also reflect food availability. This has implications for people who work at night. Think about the types of restaurants and stores that are open all night compared to during the day. The link between night shift work, poor diet, and health consequences was explored in an editorial in the journal PLoS Medicine.

Also take a look at the other elegant infographics on the  Massive Health website. They are a compelling way of presenting data about what we eat.

A cure for diabetes?

I spend much of my time talking about the benefits of a healthy diet and regular exercise to anyone who will listen–and to some people who won’t. I usually include something about the fact that, for many conditions, lifestyle change is at least as effective as medical management, certainly for preventing diseases like diabetes, hypertension, and dyslipidemia. So it was with some reluctance that I jumped on the bandwagon with a growing number of surgeons who believe that bariatric (weight loss) surgery is an effective treatment for diabetes.  This was the topic of my Health & Fitness column in today’s Aiken Standard.

Let me be clear: This doesn’t mean that diet and exercise don’t work. In fact, successful long-term weight loss requires dietary modification and daily exercise, regardless of how the weight was lost. Ideally, diet and exercise would be the method that everyone uses to lose weight–it works, but only if people a faithful to the treatment. Unfortunately, most people are not, leading to the belief that diet and exercise don’t work. And for some who are extremely obese, it is unlikely that diet and exercise could produce results sufficient enough and quickly enough to treat serious health problems (including diabetes) that are likely in progress. For this reason, many turn to weight loss surgery for a quick fix.

For years I was skeptical, but a growing body of literature, including two recent studies in the New England Journal of Medicine, suggest that obesity surgery can “cure”diabetes. [you can read these studies here and here] The results of these studies show short term benefits, so it is unknown whether this is a permanent cure or not.

Either way, diet and exercise are necessary to maintain the weight loss in the long run as well as treating other health conditions. And a healthy diet, regular exercise, and maintaining a healthy body weight are  still the only ways to prevent diabetes. The bottom line is that the true benefits of weight loss surgery cannot be realized without lifestyle change. And if you adopted a healthy lifestyle from the beginning, you wouldn’t need to even consider obesity surgery.

If you are the podcast type, there is an excellent description of these recent studies as well as a discussion of the risks and benefits of obesity surgery from NPR’s Talk of the Nation.

The K-E diet: I suppose I shouldn’t be surprised, but…

This is wrong on so many levels!

The K-E Diet: Brides-to-Be Using Feeding Tubes to Rapidly Shed Pounds

 

Just do it!

It looks like Nike, having conquered the world of sports, has moved on to the world of incidental physical activity.

I expect that Gatorade will be developing a sports drink specific for stair climbing in the near future.

Achoo! Exercise and seasonal allergies

Is it okay to exercise if you have seasonal allergies? Will exercise reduce your allergy symptoms or make them worse? Read more in my Health & Fitness column in the Aiken Standard.

A picture is worth a thousand words

A picture is worth a thousand words

A former student sent this to me today, thinking that I would like it. I do.

No, taking the escalator won’t make you fat and taking the stairs isn’t the key to weight loss.

But people who are more active, including regular exercise and incidental activity like taking the stairs, do tend to weigh less and have better luck losing weight and keeping it off.

Even those of us who should know better sometimes find ourselves on an escalator when there are perfectly good stairs nearby. Maybe reminders like this could help us make the more active choice.

Actually, it probably would make us take the stairs. There is a good bit of research showing that signs and other prompts do increase stair use and the effect lasts even after the sign is taken down.

I wonder if seeing this picture here will influence whether you take the stairs the next time you have a choice?

Would you like Pink Slime with that burger?

My latest column in the Aiken Standard is about “pink slime,” the additive, formally known as lean finely-textured beef, which is found in much of the ground beef we eat and buy. Since this product is approved for use in meat and is (apparently) safe, many of us have eaten it over the years without knowing it.

But, thanks to a recent ABC News segment from early March, pretty much everyone knows about pink slime. Although that segment is credited with starting the recent controversy over pink slime, it has been in the media over the years, including Jamie Oliver’s Food Revolution almost a year ago. If you would like to learn more about pink slime, read this update and expert commentary on the most recent pink slime developments.

Then think about this: What other foods that we commonly eat also have equally disturbing additives in them that we just don’t know about?

Bon appetit!

Exercise and weight loss…again!

Exercise and weight loss…again!

Yes, exercise does work to promote weight loss. In fact, weight loss by exercise alone results in greater fat loss and preserves muscle compared to weight loss by diet. It’s true.

But you probably shouldn’t try to lose weight by exercise alone. The best results will come from combining diet and exercise.

Yes, it is possible to lose weight and keep it off. But it is difficult, as this article explains so elegantly. Difficult, not impossible.

The Hunger Games workout

You can lose weight and get in shape like Katniss and Peeta with Train Like a Tribute at New York Sports Club.

Especially if you had popcorn while you watched the movie. At 1,200 calories for a medium size serving, you may need to go to more than one class!

Watch this before you see The Hunger Games this weekend.

The Hunger Games opens in theaters tomorrow. Based on the hugely popular book by Suzanne Collins, it is expected to be a hugely popular film. You should probably see it.

But watch this video before you go
