If weight gain is largely a normal response, by normal people, to an abnormal situation, what exactly is that abnormal situation? Calorie-Rich-And-Processed Foods (I’ll let you work out the acronym!). That’s the topic we’ll turn to next.

This is the 3rd in an 11-video series on the history of the obesity epidemic. If you missed the first two, see The Role of Diet vs. Exercise in the Obesity Epidemic (http://nutritionfacts.org/video/the-role-of-diet-vs-exercise-in-the-obesity-epidemic) and The Role of Genes in the Obesity Epidemic (https://nutritionfacts.org/topics/the-role-of-genes-in-the-obesity-epidemic).
