The cognitive ability of the brain is related to the blood glucose concentration. In other words, the brain thinks real well when it has food. Since the glucose is its food, it is good to have the correct blood sugar. Not only is the thought process effected, all areas of the brain need sugar. So if the sugar level is off, our mood will change. Usually people with a low blood sugar will be very irritable. Once they eat and replace their blood sugars, their mood will dramatically improve. This is important because weight loss dieting can often cause fluctuations in blood sugar, which in turn causes more moodiness. So some weight loss dieting can have an association bad moods, or temperament changes.
As our understanding of hormones improves, so should our diet and weight loss dieting. The goal of our lives should be to be happy, and as you can imagine, a brain with the correct fuel level is a happy brain. This ‘good' blood sugar level allows us a better chance to be happy overall, and to work on the other aspects of our lives that may be bringing us down. If you are having personal ‘troubles' and you are battling frequent low blood sugars, you are in a difficult position to achieve life changing modifications. The answer becomes learning how and what makes you tick.
