At each trophic level, energy is lost as it is transferred to the next level. As humans are at the top of the food chain, consuming primarily meat would result in a significant loss of energy compared to a plant-based diet. This would limit the amount of biomass that could be sustained by the ecosystem, and thus limit the possible size of the human population.
