Does a person's appetite prove his stomach is good?

Appetite depends on people's comprehensive health. A good stomach depends not on the stomach, but on its analytical function of food. A strong stomach can increase another person's appetite, not his. For example, if you eat three bowls of rice every day, you are only 80% full. This person has a good stomach. If you have a good appetite and want to eat every day, but eat a bowl regularly at every meal, then this can't be compared.
