Video: What If Obesity Has Nothing To Do With Eating Too Much?

Published on July 1, 2013,

What if obesity has nothing to do with eating too much? Peter Attia, MD, President and co-Founder of the Nutrition Science Initiative, says we don’t know enough about the science of weight gain, and that clinicians — and society — should stop blaming the victims…

In this TEDMED talk, Peter Attia discusses the blame many attach to people who are overweight and suffer illnesses.

He describes his own experience of becoming insulin resistant despite exercising several hours a day and eating strictly according the recommended food pyramid.

Then he describes how he changed his diet and how it made him aware that conventional wisdom concerning obesity and its relationship with insulin resistance could be completely the wrong way round. In other words, insulin resistance may actually cause obesity, not the other way round.

He presents some statistics suggesting a closer link between insulin resistance and risk of illness than there is between obesity and risk of illnes illness (obese people who are not insulin resistance do not have higher risk, lean people who are insulin resistance do have higher risk).

He speculates that the driver behind the epidemic may be the increased consumption of sugars and refined carbohydrates, but through the mechanism of insulin resistance rather than just because they are eaten too much.

He says the answers can be found by science and discusses the activity at the Nutrition Science Initiative.

Video: Debunking the Debunking Paleo TEDx Talk

Published on May 8, 2013,

There was a bit of a kerfuffle recently in low carb, primal and paleo communities after a TEDx talk and video by Dr Christina Warinner (link below), an expert on ancient diets, which was titled ‘Debunking the paleo diet.’ Few paleo commentators seemed to take much issue with most of what Dr Warinner actually said about either ancient diets or her recommendations for today, but they were a little disturbed at the way she represented paleo, which was seen as somewhat distorted. Now Angelo Coppola has written a response and summed it up in this video…

Video: How Millions of Cows Could Green the World’s Deserts and Reverse Climate Change

Published on March 22, 2013,

Low carb diets are sometimes criticised for encouraging meat consumption (although you can be a low carb vegetarian) and, in turn, meat consumption is accused of being bad for the environment because livestock is seen by some as an inefficient use of natural resources. However, a recent TED talk by Allan Savory, highlighted by the Diet Doctor, might be about to turn all that on its head…

Here’s the Diet Doctor’s take on the talk:

Could millions of cows help save the environment? Yes, says Allan Savory, a grassland ecosystem pioneer, in this fantastic new 20 minute TED-talk.

Animals grazing grass, when used right, do not turn grassland into desert. Savory used to belive that, a long time ago, but he’s now realized that was a tragic mistake (in a very personal way). The animals do the opposite. They make the desert green again.

Close to the end he claims that using this technique, turning deserts green again, could possibly bind enough carbon in the ground to make atmospheric carbon levels return to their pre-industrial state.

This would totally reverse climate change. It would feed millions of people. And it would turn grass-eating animals into environmental heroes.

If Savory’s right this is a total game-changer, and he seems to know what he’s talking about. Watch the talk, it’s amazing.
