"The feeling of satiety is not just a function of how full your stomach is. It's also a function of blood sugar levels." No, it is not. Satiety is a complex process mediated and regulated by a certain number of hormones. Leptin controls satiety, whilst the release of ghrelin induces the feeling of hunger. There is no difference between eating pure sugar and potatoes, as the latter breaks down mostly into glucose, anyway. Eating both will give a blood sugar spike but won't stop you from gorging on both unless your body promptly starts releasing leptin.
