What led to obesity is not the food per se but the wide availability of it and the change in other norms like exercise and outdoor play which changes lifelong habits. Even with a world of processed food it's rare to see a fat person who is a daily runner and that is no accident.

But this theory that humans used to eat an optimal diet and now don't assumes that humans in the past were somehow in more control of their diets than we are today and I don't think that's true at all.
