I recently received first blood results since starting Paleo in December 2010. As expected, my cholesterol is high now, but my LDL is pattern "A" and my "consider insulin resistance/metabolic syndrome" result is negative.

My question revolves around low blood glucose levels of 63 (ref 79-115). I had been fasting for approximately 14-15 hours at the time of the test and I typically IF 16-18 hours approximately 5 days per week, so this was not unusual.

I recently asked another related question regarding a second round of low energy while on VLC. First few weeks were difficult, then great energy, last few weeks back to low energy and feeling some symptoms of hypoglycemia, which I have not had since beginning Paleo.

My question is this: Could IF be negatively impacting my blood glucose or insulin levels (no results on insulin in blood test) and could this be a reason for the recent bout of low energy? If so, does this mean I am insulin resistant, releasing too much insulin, etc., and what is the remedy? I am wondering if I should skip the IF if it is raising my insulin levels (wish I'd had that checked, but I didn't). I am doing VLC 70% fat, 25% protein and 5% carbs for the past few months with a 20 pound needed weight loss. On a side note, it seems that if I skip the IF, I do not lose any weight, even if my total calories are the same.

To clarify: Is having low glucose detrimental to my health?

Thank you for any and all advice and responses.
