imo there are 3 levels to this, and many sports... pro, amature, hobbyist... if you arent competing, you are a hobbyist...
someone who snowboards twice a year still snowboards right? so someone who lifts several times a week could certainly be called a hobbyist bodybuilder.
If you arent competing, then i wouldnt stress out about it to much, depending on your goals... 10 cals worth of sugar isnt going to kill you, or make you fat. If you are drinking 5 cups of coffee though, it adds up... and candy bars? havent touched one in years, but there are better things out there for you..
guess i just wanted to say , bottom line, dont take this, or anything in life to seriously... youll never get out alive.
