Have you ever wondered why sometimes only ten minutes or so after you eat certain foods, you feel hungrier than if you ate nothing at all? That’s because you ate something with a high Glycemic Index (GI) that was rapidly digested and absorbed into the bloodstream, causing your blood sugar to rise and your insulin to spike. This chemical interaction makes you feel hungry. Foods that can cause this include: certain fruits, juice, sweetened cereal, white rice, white bread, etc. Fruit can fall all over the GI spectrum, so it depends on the fruit.
