i competed as a pro natural bodybuilder in 2010 so it's been a while um and i won the ifpa international the heavyweight division and then i um i ended up doing the ifpa world championships and plays top five in the heavyweight division um and it's difficult because it's like the amount of calories you start on is not going to be what you end up finishing on i think the lowest my calories got was just around 1900
