Re: Senator Sanders and Rep. Omar introduce Universal School meals bill
Eating food is a body thing, not a mind thing.
An adult brain consumes roughly 20% of the energy that an adult consumes based on resting metabolic rate studies. Look it up.
If you don't consume enough calories your brain starts running on ketones instead of sugar and will see decreases in cognitive ability. Again, look it up.
Thinking and learning requires a lot of sugar.
You are talking about the brain. The brain is part of the body. The body gets hungry, not the mind. The mind simply acts according to the amount of the eaten nutrition that reaches the brain.
EDIT: Besides, it works just the opposite of what you are thinking. A hungry mind is a mind that wants to learn. If the body is starved, the mind gradually loses its hunger for knowledge. Feed the body the right amount, and the mind's hunger increases.
