Guest, we'd love to know what you think about the forum! Take the Diabetes Forum Survey 2025 »

Message: <blockquote data-quote="George_Henderson" data-source="post: 1273198" data-attributes="member: 342029">I think a very simple explanation of the energy question is that fat and glucose are in competition to supply energy, like (occasional) trains and (fairly constant) cars compete to use level crossings, and insulin is like the crossing control and barrier arms that always stops fat (cars) and lets glucose (trains) be used when you eat a meal..In diabetes this control is defective and the train and car can be on the crossing at the same time; that is, stored fat is still available when glucose is eaten, so BG goes higher. But if you don't eat much glucose, the fat gets burnt and doesn't push up the BG. You might do this losing weight and burning stored fat, or eating more fat and staying the same weight.Basically stopping most train traffic so that defective crossings are less dangerous and can be fixed (which is what usually tends to happen, to a greater or lesser extent) and cars (fat) can move freely.I hope this analogy isn't too confusing.As to nutrition, every whole food contains the nutrients that are essential to create and use the energy in it, more or less. Animal foods (if you eat nose to tail) actually contain anything the animal needs, and its needs are very similar to ours. Plants supply extra of a few things humans need more of, like vitamin C - grains are not a source of vitamin C.</blockquote>
