Dr. Ron Najafi compares two models of weight gain: the traditional calorie-balance model versus the carbohydrate-insulin model. In one, overeating causes fat storage. In the other, insulin drives fat storage first, then overeating follows. The difference changes what actually works.

Compare the two models side by side. The drivers are slightly different. Here it's caloric content, Here is specifically insulinogenic content. Ultimately, positive energy balance comes before adipose tissue storage. Here, positive energy balance comes after adipose tissue storage. And you might say, like, who cares? Why do we care? Well, ultimately, it does matter, because it gives us something we can do, like get rid of the sugar. If this is the correct model, it relies on everybody to do their own thing, which is what we've been doing, and it hasn't worked. Policy change is contingent on which model is correct and which model any given society adopts, which is why we are in this conundrum that's not getting any better. Most recently, David Ludwig, who's a proponent of the carbohydrate insulin model.
