The first part of the premise, however, is unrelated to the second (in your version or mine). We've evolved to like (natural) sugars like fructose because they provide calories and our ancestors with a sweet tooth were more likely to survive. The "appetite buttons" would be the hunger induced by the insulin spike triggered by sugar.
If you cut your sugar (and that increasingly means HFCS) intake way back for a few months you will notice that some vegetables and whole grains are remarkably sweet, for example- and you'll be healthier.
This may be true, but how is it relevant to the OP?
