To take it a step further: Is it immoral to eat whole foods for all 3 meals a day?

Research has shown we get most of the nutrients we need from our first meal (of whole foods) each day. We only need calories from that point on. Shouldn't we then just try to get the most efficient form of calories, so long as those calories don't do harm? Leave the other 2 nutrient-rich meals for the rest of the world.

He frames it as "this is not what Americans want." But just because we can increasingly eat 3 nutrient-rich meals doesn't mean we should. In fact, it means the opposite -- that we should give those meals away because we can.
