a lot depends on ur metabolic needs. this does not mean only the energy expended on physical activity and mental effort, but also on filtration of omnipresent toxicity. put plainly: if u do not filter what u put into ur body (air, water, food, and light sources), then u become the filter and be ready to work overtime.

imagine a monk who steps slowly, meditates while walking, who rises at sunrise and falls asleep shortly past sunset, living a quiet peaceful life, breathing clean mountain air and drinking natural spring water - do u think he needs to eat NY steaks daily in order to function at 100% capacity? probably not.

i am not going to recommend what to eat or how to eat it, only to think deeply about the needs of the body and brain.
