Hi changemeohyah, I just posted a response to your "depression is a spirit" post about the health risks of fasting at the onset of depression (hypoglycemia). I caution against fasting because of the self-destructive thought processes that develop in a human brain deprived of Glucose (the "good" form of sugar that our body needs to survive!) As sunangel wrote, our bodies crave sugar and carbs when we are depressed, and it is precisely because our Glucose levels are probably low. Unfortunately, the sugars we crave most: the cakes, cookies, and chips, are most often made with high-Fructose corn syrup and/or Sucrose...Too much of these sugars can actually mess up your body's ability to absorb and utilize Glucose. You crave and may eat any sugar...but your body really needs Glucose, and oddly, eating sweet foods is not the best way to get glucose into your system.
This site has a good write-up on Hypoglycemia:
http://www.chronicfatigue-help.com/five.htm
"The result is a state of low blood sugar which can cause an alarming number of distressing symptoms -fatigue being only one of them. Other symptoms include headaches, dizziness and feeling faint, irritability, depression, difficulty in remembering, blurred vision and in most cases an overwhelming craving for something sweet or a stimulant such as tea or coffee." *
"If you are hypoglycemic, you are essentially addicted to sugar and you are fighting something which can be as difficult as an addiction to cigarettes or alcohol. If you do slip, pick yourself up and start again. The first week or two is the hardest in starting a low-sugar diet that's when the cravings will be at their most intense. Eating even a small amount of something sweet can actually trigger a full-blown binge because of the way your body reacts to sugar."
