Option 1 -> A glutton is someone who habitually eats or drinks excessively; specifically refers to overeating.
Option 2 -> An epicure is a connoisseur who appreciates fine food and drink; focuses on quality, not quantity.
Option 3 -> A gourmand enjoys good food and may eat large quantities, but less negative than "glutton" and can also mean a food connoisseur.
Option 4 -> A pagan refers to someone with non-mainstream religious beliefs or no religion; unrelated to eating habits.
Hence, Option 1: glutton -> This is the most precise term for someone who eats too much, as it specifically denotes excessive and greedy eating habits -> correct
