Lots of great points and questions. Thanks to all who are participating, and thinking, thinking.
High fructose corn syrup is just one more quickly-digested sugar bolus, completely devoid of any other useful nutrients. Even the best organic fruit juice is not much better, from a carbohydrate perspective (same issue with quickly digested bolus of glucose). Our bodies were not designed to handle large amounts of simple carbs all at once. Also, we can have significant insulin overproduction/resistance going on without (yet) having elevated serum glucose levels and frank type II diabetes.
The trial of mice and people that looks at levels of glucose and/or ketogenesis could still be linked to my insulin overproduction/resistance discussion, since the body does produce insulin in response to blood sugar levels.
My personal thoughts, totally unencumbered by evidence, are that fasting will not make any difference (at least not for the reason you surmise - lowering blood sugar). In the absence of insulin resistance and/or high sugar boluses, blood sugar is maintained fairly tightly by the body and can never drop below a minimum because all cells, not just cancer, would not survive. When I read that cancer uses more glucose, that does not mean to me that it needs higher levels of glucose to thrive, but simply that it siphons off more than the other cells do, whatever the serum value of glucose at the time. And as the glucose is used (metabolized), whether by normal cells or by cancer cells, the body, thru several different mechanism of regulation, insures that the serum glucose is maintained so that energy is always available.
