To a point, I agree with you, but what most people don't realize is that your genetics, and those of your ancestors, change as a result of the food you eat over time. (GMO anyone?)
So, yes, it is diet as a direct causation, but genetics play an indirect role over the long term in that they adjust to the shit food we put in our bodies, making the problem a compounding one. This would explain the graph.
is that, over time, a lineage of people lose their insulin sensitivity due to it being spiked every few hours with every corn syrup filled coke, latte, and simple carb heavy meal they ingest. Basically, they are burning out their thyroid while losing their insulin sensitivity. Which will make it pretty damn difficult to lose fat regardless of how much of a calorie "deficit" you are in. This much is pretty obvious. The idea that it then becomes a genetic disposition is much less so, and nothing that I can prove, or will try to.. but seems just as obvious to me. I've seen evidence to support this, such as the spike in diabetes and a few other indicators, but nothing conclusive.
