I fully agree that, as you say "energy poisoning" is one of the major causes of modern disease, is THE cause of diabetes, is the primary cause of gout, and also increases risks of cancer and atherosclerotic diseases.  And probably the most important one to correct.

But (and this is where we differ) I also think saturated fat (apoB to be precise) accelerates atherosclerosis. And so limiting red meat (as long as you can do so without gaining wait) is another good target for health.

But avoiding energy poisoning is the bigger of the two levers.
