Seriously, the sugar substitutes are formulated to bind to the same receptors that sugar binds to on the taste buds. So when they do that, they will trigger all the same reactions that sugar does (production and secretion of enzymes that digest carbohydrates, etc). So there is some truth to the bit about insulin production and all that. As for the substitutes being better for you, I don't think so. The digestive system has evolved to break down naturally occurring compounds, synthetics don't sit well.
Now, keep in mind, I don't like supplements. Athletes, in general, have the worlds most expensive urine, and I work with enough of them to know. Eating a balanced diet of real food (this means that a can opener, a box, the microwave and the freezer door are usually not involved; pots, pans, the stove, the oven, and the grill almost always are), containing mostly complex carbohydrates from plants and whole grains, a smaller quantity of protein and dairy, and a little lipid, will do more than all the supplement you get from GNC.
