Have you ever had that experience of eating a meal and then one hour later feeling very sleepy? I often had a routine of having a cappuccino in morning. Then for lunch having eggs on white toast, with some cake to follow. Mainly just because I liked it. An hour after eating this relative small lunch, I would feel sleepy / sluggish and not at all like going out for a hard training ride. I then discovered (or now paid attention) that white bread has a very high GI index. (a high GI index means it rapidly raises your blood sugar levels). White bread is nearly as high as pure glucose. Taking this white bread and cake had the effect of putting a big increase of sugar into the blood. However, because you are not exercising, the body doesn’t need this extra sugar.
