> For example, if you consume a can of Coke, your body is going to try to process the sugar in it all at once. But if you consume a donut with equivalent sugar, the fats and oils in it slow down the digestion process. Thus your maximum insulin load(which is the largest immediate factor in creation of fat tissue) will be lower with donuts. Fruit achieves a similar load-lowering quality through fiber instead of fat. You have an understandable and common misconception of glycemic index. You cannot always intuit which foods will have a higher glycemic index. For example, you incorrectly seem to believe that cola has a higher glycemic index than a donut. In fact, donuts have a higher glycemic index than do colas. You should not conflate your subjective feeling of "badness" with the objective measure of circulating insulin or glucose (unless you have rigorously established the correlation, which is not obvious). Subjectively, I feel just as bad when I only eat a donut as when I only drink a coke.
