If you are already eating meals consistently and don’t let yourself get to the point of physical impairments from not eating, then I can see how my methods wouldn’t work for you.
My suggestion of having easy meals was just to facilitate eating meals consistently, no matter how you feel. I found when I ate a meal at the same time every day no matter what, after a year or so I actually developed the feeling of needing to eat at that time of day. But if you’re already eating at the same times every day and you still don’t feel a need to, then I don’t think my experiences can help you :(
