Document Summary
If you lower an animal"s insulin level, it becomes hungry and eats a large meal: give moderate level of insulin, eats much less! Not exactly when you give large amount of insulin, that converts most glucose to fat, less glucose into bloodstream. So, brain detects the glucose deficit, initiates hunger: the animals will now eat a large meal just the same! Again, not exactly diabetics have huge amounts of glucose in bloodstream, but they are always hungry!! Under normal conditions, blood glucose levels can stay relatively stable for hours, even days, but we still get hungry . Multiple signals in addition to glucose and insulin regulate hunger and satiety! The whole system is designed so that blood sugar levels stay relatively stable for the day. There are lots of safety checks within the system that ensure blood sugar levels!! If you don"t eat, it will start stripping the energy from your body storage, in muscles etc .
