First, a little background: David Ludwig is a professor and researcher at both Harvard Medical School and Harvard School of Public Health. He has both an M.D. and a Ph.D. and is one of the world’s leading researchers on the science of optimal nutrition. He’s overseen dozens of diet studies and authored over 100 peer-reviewed articles.

Well, before we even get into that fMRI machine, we see that the individu
