Fact - Eating 2,400 Calories daily is what most people need.
This is true!
Just because you "think" you don't need that much, or, because you've trained your body to "exist" on less, does NOT mean that's right. It's not even right for you...for those who think they can say that.
Your body burns Calories every hour of every day of every week of every year. Your body never stops burning Calories.
