You will also die if you eat precisely the amount of calories you burn every day.

There exists something called a "feedback loop", something common in biology. You would probably find it interesting, you should look it up.

Basically, it means that if you try to chronically eat, say, 1% more calories than are burned, your body will try to burn more calories to compensate.

I'm not sure I grasp the rest of your comment, could you try again to explain? The wheat farm your ancestors worked did not provide the excess of cheap calories available to the present day American.

That is the intended conclusion of my post, that body fat is obviously regulated biologically, and suggestions that changes in obesity rates are due to the increased availability of food (implying that it was regulated by some sort of precise cycle of starvation in the past) or individual choices (implying that most people are measuring portions and keeping a running tally) are in conflict with that.

You haven't made that point and I disagree with your conclusion.

Your error is claiming some "precise cycle of starvation" is necessary to explain obesity via increased caloric availability.
