Most people do not count calories and calorie counts aren’t accurate anyway. The people sitting around counting calories because they have to are afflicted with the same thing that obese people are, they’re just putting in. A bunch of effort to manage it (or more likely actually aren’t).

The issue you are missing is that the real question is not “can we create a totally artificial situation where one of the outcomes is managed” but instead “why isn’t the system that manages this in healthy people working?”

In the counting calories example, it’s like saying the answer to diabetes is an insulin pump. People who d think this way are missing the point and basically are engaging in the shallowest of thought.
