Could someone tell me what the "normal" amount of food to eat in a day is? And maybe what types of food you're supposed to eat every day? Im trying to recover from an ed and I have no idea what normal is. For instance I'm taking my mom out to dinner tonight, so if I ate a bowl of ramen for lunch would that be too much?.. 

"Normal" depends on several factors, like age, gender, and activity level. A good average to shoot for would be 1800 calories if female and 2000 for male.

Depending on where you are going out to eat, most chain restaurants pack in a day's worth of calories in many of their meals. While just eating ramen for lunch you should still either look for lighter food on the menu, or just ask for a box when you order so you can put half your meal away right away and save it for lunch the next day.

Think about what you would give someone else to eat and how much, then eat that yourself.  Watch how much food a normal person consumes. All the best to you.

Good rule of thumb is to go heavier on the dark green vegetables, around 6 oz (depending on your size) of protein (fish, chicken, lean red meat), and maybe another 6 oz of a non-processed starch (Brown Rice, White Rice, or potatoes).
