If you read further, a little part of that section actually does make sense - it may be true in terms of amount of food consumed. If you like calorie-dense food, you don't really have to eat insane amounts of it to get way over your TDEE. They even mention that you can get 3k-4k kcal in a single meal in a restaurant (edit: even though there's no way you're a human if you can eat that). The rest is, of course, fatlogic bullshit.
