Do each of us know what we need best?

I unfortunately spent some time on a different sub and got some hardcore opinionated people telling me what I should and shouldn’t do as far as my eating plan.

I have schizophrenia and spend a LOT of time just lying in bed outside of my sleeping hours, where, as you can imagine, I’m burning very little calories. For this reason, I feel I might be a good candidate for OMAD, but I want to do it my way, which is to still eat healthy and not stuff my face with 5,000 calories in one sitting. I’m already overweight and the weight is not coming off no matter what I am doing. Is it okay to do OMAD AND eat relatively healthy and stay around 1,000 calories a day if I am a 5’0 ft female who’s in bed or sitting all day?
