What is considered a ‘normal meal’?

I’m literally so confused. I have had Ana for many many years and so I know I can’t rely on my brain for what is a ‘normal amount’ of food.

And the internet is just overwhelmed with diets and clean eating and blah blah blah. So I just want to know what a normal meal is.

What is the normal amount of calories in a meal and how big/what’s in the meal.

Please help!
