over the next week jim, carry on eating what you eat and work out how many calories you are ingesting per meal and the times you are ingesting these calories
then, in some sort of power point presentation type display, work out when you have eaten the most and when you have eaten the least and work out an average calroie per hour chart
the next week start doing some excersises to compliment your new found healthyness and do the same with the calories per hour chart
this will tell you, eventually over the coming weeks, how much you need to eat per day and how much you could possibly eat the ame of to give you extra energy to work off in the shape of running and jumping and sex and stuff

eventually you will be able to eat "heathly" enough to carry on with your activites wihtout feeling tired and washed out

then show us the new imporved jim come ford fair next year with rippling musles and bulging torso
