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.
