calories vs kcal

Howsit peeps?

just a question here.I've read a article some while back stating in order to grow, you need be consuming 4000+ calories.

however some food I've seen state they contain 40kcal.

now a quick google search stats that 1kcal = 1000 calories. is possible that some food that small to contain 40 000 calories? i think somewhere something is wrong.

thank

they the same thing.. 40kcal is 40 calories... kilocalorie is actually the native word that has been shorted to calories..
