What do we really know about nutrition and obesity? Peter Attia answers your questions on Facebook

Join TEDMED Speaker Peter Attia, MD, for a Facebook Chat on Nutrition & Obesity on Thursday, 6/20 at 2pm ET

Can we trust anything we think we know about nutrition?  What do we really know so far about how our food intake and our weight gain? Why are we working harder than ever to eat well and be healthy, with no reductions in obesity and with diabetes rates skyrocketing? Could it be that official dietary guidelines are based on science that’s not rigorous enough to draw real conclusions?

TEDMED 2013 speaker Peter Attia, a physician and former McKinsey & Company consultant,  started a new organization, Nutrition Science Initiative (NuSI) to thoroughly investigate these questions and more, along with journalist Gary Taubes, author of “Good Calories, Bad Calories” and “Why We Get Fat.”


This Thursday, June 20th at 2pm ET, Peter will answer questions about NuSI’s work to date, and what he sees as the best way to understand and combat obesity. Join us to discuss his contrarian and potentially revolutionary approach. Check out the Facebook event page for details and to RSVP.

Peter Attia’s NuSI plans three studies with new approach to nutrition and obesity

What’s really driving our scourge of obesity and its related metabolic diseases, including diabetes, Alzheimer’s disease, cancer, and heart disease? The medical community generally holds that we eat an overly large number of calories, causing an “energy imbalance” that leads to fat accumulation — and most of its advice to the general population speaks to that: “Eat less and exercise more!”

Yet, after 50 years of studying the problem and about a decade trying hard to fix it — mainly via health messaging — we continue to gain weight exponentially. Obesity has increased 250% since the 1960s, and diabetes more than five-fold. Why can’t we solve this?

For starters, what if all of our efforts to fight weight gain have been based on inconclusive science? What if our “treatment” is then incorrect, rather than conventional wisdom that says people just can’t follow it?

TEDMED 2013 speaker Peter Attia and his non-profit organization,Nutrition Science Initiative (NuSI) hope to help science, and eventually public policy, reach the truth. Attia and co-founder Gary Taubes, a science and health journalist and author of “Why We Get Fat,” founded NuSI a year ago. They hold that research on nutrition has not been nearly rigorous enough to date to make existing claims about the relationship between nutrition and health due a host of factors, including a lack of proper controls, difficulties in meticulously monitoring subjects, and insufficient resources to conduct the necessary experiments to show cause and effect.

Supporting their claim, a meta-search published in the New England Journal of Medicine last January concurs, saying that most popular dietary recommendations concerning obesity, from the value of eating breakfast and more fruits and vegetables, to the evils of snacking, are unproven.

To begin its quest, NuSI is funding and facilitating what it hopes will be the most rigorous research to date on the relationship between nutrition, obesity and metabolic disease to date, starting with three large experimental collaborations at six leading academic institutions over the next three years.

NuSI will release details on the projects in the next few months. We do know that, as the Wall Street Journal reports, the Laura and John Arnold Foundation (LJAF) of Houston, Texas has recently agreed to fund approximately $40 million of research over the next three years. We’ll give updates here.
