His latest, "Metabolical: The Lure and the Lies of Processed Food, Nutrition, and Modern Medicine" goes deep into the details of how changes in our food supply have damaged our metabolic health. (The created term "metabolical" is actually a portmanteau of the words "metabolic" and "diabolical.")

"I wrote it because nothing else has worked," Lustig says. "Part of the problem is this is such a complicated issue. There are too many stakeholders and you have to find a method for making everyone happy. Until you do, you can't solve it.

There is a way to actually solve this, [but] every stakeholder, whether it be the patient, the doctor, the food company, the insurance industry, the medical profession, Wall Street and Congress … has to understand the same thing. They all have to be working off the same set of facts. You see what happens when you don't work off the same set of facts.

So, my job was to put all of this in one volume so that everyone had access to the same information, and then we can go from there. I lay out in the book what the argument for fixing the entire food system is, and how everyone can benefit from it, even the food industry."
