Since obesity has been rising for decades and causes so much loss of life and disability my next few blogs will focus on issues that can lead to overeating.

Most diets rely on creating a negative energy balance to lose weight. This means that the body is taking in less than it needs so it uses the energy we have stored such as glycogen, fat and muscle protein. Humans require a certain amount of calories each day just to support necessary functions like regulating heart rate, controlling our breathing, digesting food and other automatic processes. This bare minimum of energy we need to support these life preserving functions is known as our basal metabolic rate. Believe it or not but even as we sleep we are burning as many calories as when we are sitting down watching television.

The finding of electricity and invention of light bulbs have changed our whole sleep/wake cycle. Our body may be unable to differentiate artificial lights from daylight, and this can have severe consequences on our entire bodily systems dependant on the light/dark cycle of the day.

By: Robert Melick

Full Moon, Moon, Midnight, Witching Hour

Scientists may still be perplexed about the function of sleep, but they do know that it affects disease risk, especially diabetes, hypertension and heart disease. So, how much sleep do we need? What is the “optimal” amount? Well, that is hard to say. Everyone is different and requires different amounts of sleep, right? Indeed. But there appears to be a range of sleep where below that range or above that range, the chance of developing one of the previously mentioned diseases increases.
