Final answer:
A person who eats too much is known as a glutton, which is different from an omnivore, who eats both plants and animals without necessarily overeating, or a reveler, who partakes in excesses occasionally and socially.
Step-by-step explanation:
A person who eats too much is best described as a glutton. This term refers to someone who habitually eats to excess. In the context of health and dietary habits, it is important to distinguish between different types of eating habits and disorders. For instance, binge eating disorder is a specific condition where an individual repeatedly consumes large quantities of food and subsequently feels guilt, but does not engage in purging. This disorder can lead to adverse effects such as excessive weight gain, obesity, and other health complications like high blood pressure and type 2 diabetes. On the other hand, omnivores are organisms that eat both plants and animals, and not specifically associated with overeating. A reveler is often associated with someone who enjoys indulging in pleasure, like eating and drinking to excess in celebratory situations, but it does not inherently indicate chronic overeating as in the case of a glutton.
