[ted id=1774] In this compelling TED talk, Dr. Peter Attia says that insulin resistance and diabetes cause obesity — not the other way around as the conventional wisdom holds. More importantly, he says it's the refined grains, starches, and sugars in our diets that cause insulin resistance in the first place. Meaning, it's not how much we eat but what we eat -- more proof for the argument that all calories are not the same, contrary to what the food industry wants us to believe. It won't be long before Big Food will have to acknowledge the science and take responsibility for its poor quality food products, rather than insisting that all calories are the same and scolding Americans to simply "eat less and exercise more." Dr. Attia says that obesity is really just a proxy for the underlying illness that is insulin resistance. He says that by blaming the obese, we are blaming the victims in a food system gone awry. Our processed food supply — which is heavily reliant on refined grains and sugars — is the real culprit here.
