Fainting from low blood glucose? Sounds like your metabolism is not very good at burning body fat. One effect I've noticed from Leangains-style Intermittent Fasting is increased metabolic flexibility. Ie I don't need to eat breakfast and lunch and I function fine without them, because my body knows how to use more than one energy substrate. Then again, my job is not very physically active, so that could be a confounding factor.
