Are you fasting or something during the day? Even still, if you're hydrated, you likely have plenty of energy reserves just in fat stores. Are you sure you're not ill? Could it be you THINK you're starving? If your body is used to being fed at that hour, you will have an actual physiological hunger response like Pavlov's dogs, but unless you haven't eaten in quite a long time or you have a medication or possibly dehydration issue, you should be fine. I find hunger comes in waves. It's mostly mind over matter. Try fasting and allow your body to get used to not being in a constant state of being fed. It'll change your life. Maybe not the answer you were looking for, but just something else to consider. I did and haven't looked back. Regardless, good luck on your journey.
