CHRONIC FATIGUE
Possible Causes - 3

Chronic fatigue may have many causal factors. This series of blog posts offer a few ideas you can check out for yourself or with your physician.1

Self Care Issue

Food allergies / sensitivities: Although often overlooked unless they produce obvious symptoms (rash, swelling of throat, etc.), these may burden the digestive, lymphatic, endocrine and other systems. Alcohol and artificial sweetness such as appertain have also been implicated. Be particularly suspicious of items that are associated with cravings or that are consumed regularly. What food would you not want to give up? That one is often the culprit.
Glycemic factors: Foods that are higher in carbohydrates may cause a spike in blood sugar and result in a blood sugar drop a couple of hours later. While simple carbs may offer immediate energy, adequate proteen, complex carbs and a small amount of healthy fat keep blood sugar level.
When food is consumed: Six small meals a day has been suggested for those with low energy. However, research involving leptin, a newly discovered hormone that signals the brain regarding hunger, has led some to suggest three meals each day (balanced portions of protein, carbohydrates and fat), spread five to six hours apart without snacking between, is a better choice for most. It is suggested that this results in a better interface of a number of energy-related, appetite, and sleep hormones, including adrenaline, insulin, leptin, melatonin and cortisol.1

I have personally found that for me five to six meals a day does not work well. Furthermore, snacks between meals don't work either. There is a tendency to either overeat at each of the small meals and snack too much where snacks are concerned. Therefore, what seems to be best for me is three squares with no snacks.
