Investigative science journalist and author Gary Taubes gives a lecture at Cornell on November 10th 2014.

There are numerous versions of this lecture on YouTube, but this one is the most recent and complete version I found.

The lecture might be too in depth for some watchers, but he really covers a lot of the issues out there concerning the Standard American Diet and the generally accepted obesity-energy paradigm (model).

Before you watch, you can ask yourself why you think people get fat. Take a few minutes to think about it, maybe even write down the logical steps a regular person should follow to make themselves put on weight.
