How do you know when to eat

I feel like it’s such a silly question but literally yesterday I decided I wanted recovery without being forced and for the first time in my life this is my decision. the thing is though I literally don’t know when to eat which sounds so silly bc the answer should be simple but I fear after everything it just isn’t. I’m doing this all on my own as I don’t really have access to support so I was just wondering if anyone had any advice or this or just about starting recovery in general
