Start with 7 spoons. Or 8. It doesn't really matter because you just need something to start with, then you adjust it if it's too little (you had more energy after running out of spoons) or too many (you ran out of energy but still had spoons left). It's up to you what you spend spoons on. If you find that deciding what to eat is mentally costly, then yes, spend a spoon. Or set a habit to not make decisions about food and eat the same thing for lunch.
