@GreatestSin, half of the make-up of chakra is the bodily energy. So yeah, having a healthy body will make a huge impact. And work-outs don't usually make people hungry, just tired. They get really hungry later.

It doesn't only take a lot more chakra control, but a lot more chakra too. So it's really impractical.
