Opposite experience of everyone else. Feel tired, lethargic, slow DURING my fasting window, energy comes back AFTER I eat

Anyone know why this could be? Everyone I know that does IF swears by it and how much energy/mental clarity it gives them. For me it just feels like the opposite. via /r/intermittentfasting https://ift.tt/2NcUVlV https://ift.tt/eA8V8J
