Fructose and consumption
Sorry if I am getting in the middle of the debate here.
Since fructose is sweeter than sucrose (almost twice as sweet, in fact) it might very well mean a decrease in the consumption of both fructose and glucose.
I thought that fructose did not have an effect on the desire for more food while glucose did have a suppressing effect on food consumption.
If this has already been cleared up then feel free to ignore.

Re: Fructose and consumption

It's possible, but even if that were true, I don't think it would matter. When you drink soda, do you drink until you stop being hungry? Or do you drink until you stop being thirsty? Or, in fact, don't you drink until the container is empty? If you eat an apple - high in fructose - do you stop about 4/5ths of the way through when you stop being so hungry, or do you eat the entire apple, regardless of its size?
In experiments, you can make people eat about four times as much soup as they normally would, simply by using a "trick bowl" - fed from the bottom by a secret tube that replaces the soup in the bowl as they eat - that keeps the soup in the bowl at a certain level. In other words, your brain tricks you into being just as hungry as it takes to finish all of the food that is in front of you.
So replacing some amount of glucose with a smaller amount of fructose, in practice, isn't going to make you eat any more. You were always going to eat the whole cheeseburger and fries, simply because they're in front of you. You were always going to finish off the whole can of soda regardless of what is being used to sweeten it.
