What you are describing is an acquired trait - An response of the organism to a condition. Acquired traits are not heritable. The trait must have a genetic basis to be heritable. So if what you are saying about brain growing in response to starvation is true, it would only explain why the starving individual's brain might be larger, it can't explain why the brains of his non-starving offsprings also got bigger.
