Every morning i get up at 6am and go for a 2.5 ish run. i come home and then eat a bowl of cereal then i go on a walk with my mom and it's about the same distance...when i come home i sometimes feel lightheaded. I know you would think i wasn't consuming enough calories but when i had just eatten breakfast about an hour ago should i really be hungry? sometimes at about 9 am i will eat toast or a rice cake with jelly. let me know if this is right or what you think.
