Some questions about starches vs. fructose:
1) Why does Ray repeatedly mention that starches are more 'harmful' and likely to lead to weight gain if fructose is stored as liver glycogen, then converted to glucose when it's used? I don't understand how or why eating fructose in the form of fruit or sucrose in the form of table sugar would have significant benefits over eating glucose in the form of starches.
A quote from Lyle McDonald's Body Recomposition site:
"...dietary fructose, found primarily in fruits must first be converted to glucose (in the liver) prior to release. That is, contrary to some claims being made, free fructose is almost never found in the bloodstream in large quantities unless it was put there through infusion. Rather, dietary fructose will either be stored in the liver as glycogen (see below) before being converted to glucose and released into the bloodstream, or simply converted to glucose and released after consumption."
2) In Lyle McDonald's UD2, he says that ultimately it doesn't matter what type of carbohydrate you use to to a carb load, but that fructose tends to give inferior results to starches/glucose because fructose is used preferentially by the liver and is not very effecient at being used to refill muscle glycogen. What's your take on this?
