The most I can stomach seems to be 2500
My partner ate about 3k to 4k calories a day before we met. I meticulously stretched his stomach out over a period of time until he could eat over 10k in a day.
Some things to keep in mind:
Don't eat filling things. If it takes a while to digest it, you'll be less likely to eat more later.
Adding sauces, cheese, dressings, and other things to food bumps the calorie count.
Regular overeating stretches out the stomach.
Eating small, frequent meals helps you eat more calories a day.
