PSA: Don’t listen to Gwyneth Paltrow’s health advice

I’ve mentioned before that taking advice from unqualified celebrities when it comes to health is a bad idea. While they might be well intentioned, good intentions are not the same a good advice. On that note – please stay away from – the health, wellness and lifestyle business operated by Gwyneth Paltrow. There’s too much in it that is either misinformed of frankly dangerous to take a chance that something in it might be useful.

High expectations and anxiety impact weight loss

According to research by behavioural scientists from Australia’s CSIRO, most Australians tend to over-think, have too high expectations and are anxious about failure – all of which can derail the best intentions when it comes to shedding unwanted kilograms (or pounds if you prefer).

They found there are five behavioural “Diet Types” with the over-thinking, anxious perfectionist the predominant type.

Correlation, causation, flaky science and trust

Debunking Food MythsA recent article on the weight loss benefits of eating breakfast says

That doesn’t mean particular breakfasts can’t help some people control their appetites, or bring other benefits like energy. Schlundt’s study was tiny. But it shows how easy it is to simplify the complexities and limitations of nutrition science and cherry-pick the findings.

The point of the article is that choosing a single study to prove a point is easy. When you’re looking at a “fact” a single data point is not enough. The reason peer review is so important in science is that being able to repeat a study is critical.

BMI and GI – can we trust the numbers?

The trouble is, niether tool is perfect nor do they take into accout the differences in our indivdual body compostion or metabolism.

Sugar lobby paid for favourable research from Harvard

SugarIn news that comes as no surprise, it’s been found that the sugar industry paid for research that found sugar didn’t have a role in coronary heart disease.

Harvard nutritionists published two reviews in a top medical journal downplaying the role of sugar in coronary heart disease. Newly unearthed documents reveal what they didn’t say: A sugar industry trade group initiated and paid for the studies, examined drafts, and laid out a clear objective to protect sugar’s reputation in the public eye.

This is why it’s important you critically read all research and ask questions – particularly when the outcomes of a study can benefit one particular group. Also, it highlights that even highly respected institutions like Harvard can be manipulated.

Dairy and weight management: what’s the story?

imageA recent article, published at the CSIRO blog discusses the impact of dairy product consumption on weight management. I hate the term weight loss – it implies lighter is always better whereas healthy is what we are really striving for.

There is no one-size-fits-all (excuse the pun) solution we are advocating here – for various reasons, you may prefer a different dietary route to weight loss. But, for many people, increased dairy intake can help knock off the kilos while still staying healthy.

McDonalds giving wearables in Happy Meals

McDonald's trackersKids in Canada and the US can get a fitness tracker with their Happy Meals at McDonalds., tracking steps and encouraging children to burn off those calories. It company has launched the wearables to run parallel with the Olympic Games urging users to “Keep up with your friends and your favourite athletes,” on its website.

The trackers (McTrackers?) count steps and encouraging children to burn off the calories from the meal they just consumed. It company has launched the wearables to run parallel with the Olympic Games, perhaps in an effort to deflect or distract from constant accusations about the food giant’s nutritional quality and links with childhood obesity.


Thinking about exercise can deliver benefits

mind-bodyResearchers at Florida Gulf Coast University conducted research with 60 college students, half of whom had a high need for cognitive stimulation. The others preferred to avoid anything too mentally taxing.

Both groups were outfitted with fitness trackers, which showed those who craved a mental workout were far less likely to do a physical one during the week.

If their deep thoughts include exercise, other research shows they might just be able to trick their body into believing it got a workout.

To top it off, some Japanese research has found that looking at sweets can cause your body to retain more calories.

In other words, getting your head in the right place may have profound effects on your health.

Talking to young people about body image

feet-on-scalesBy trying to steer teens away from unhealthy lifestyles, we could well be pushing them into anorexia, bingeing or bulimia.

That’s what the research suggests. With soaring rates of obesity and eating disorders in kids, today’s young people are getting powerful messages targeted to help them make healthy choices. But at the same time, the prevalence of eating disorders has actually increased among young people.

Research says aerobic exercise increases motivation for dessert images

dessert-chocolate-brownieResearchers from the University of Massachusetts Medical School and Case Western Reserve University recently found exercise makes people more likely to crave dessert later on.

The researchers recruited 88 college students for a test called the “approach avoidance task”. It’s been used in past research to measure automatic reactions to certain stimuli. The volunteers held a joystick as they looked at pictures of dessert foods interspersed with shots of everyday household objects.
