Final answer:
A person with more muscle metabolizes food more quickly than a person with more fat because muscle tissue burns more calories at rest than fat tissue.
Step-by-step explanation:
A person with a high fat-to-muscle ratio metabolizes food more slowly than a person with more muscle because muscle tissue burns more calories at rest than fat tissue. This means that even when the body is at rest, more energy is being expended by someone with more muscle compared to someone with more fat. Therefore, a person with more muscle has a higher metabolic rate, allowing them to metabolize food more quickly.
