"It's only very recently that in our Western society we've had excess food," says Frost. Throughout evolution we lived with very little food, and it came in fits and starts. Our physiology is geared to driving us to eat."If there was a food component that suppressed appetite, to survive you'd need to totally avoid it." Another reason that no food or drink could substantially suppress our appetite long-term is because our bodies are designed to maintain a near-constant weight, says Kohlmeier.
