I work fulltime on a meat store and Im always stand up to serve clients that means I have a very active job. If I eat a solid meal at 1PM and lets say I dont eat till 6PM, can I assume Im on an empty stomach?!?! Im asking this cause I tried to get up everyday at 6AM to do my cardio and I´ve been doing it but its killing me and its affecting my job cause I get too lazy after morning cardio
