It's not good to not be eating @MathsMagpie maybe you need to come down a dose, not eating is where health problems start ( I've been on MJ over a year so I totally get the feeling and always found going down a few clicks helps).
I eat good, home cooked meals where I can, I don't cut anything out, eat full fat etc and try to stick to as unprocessed as possible. But I still have a takeaway at the weekend and my Sunday dinner, my portions just aren't as big as before.
I do intermittent fasting so tend to skip brekkie, for lunch I'll have a sandwich, or salad, baked potatoes, scrambled eggs on toast with some veg etc, sometimes I'll have leftovers from the night before.
For dinner it's spaghetti Bolognese, sausage mash and veg, chicken curry etc, again I don't cut any food group out but I really focus on lots of protein and veg.
I have an apple every day for fibre, and rarely snack, except for maybe a small piece of chocolate or a biscuit in the evening with a cuppa.
I drink only water or tea/coffee (and sometimes milk in an iced latte), and I have massively cut down alcohol, literally only a few drinks every few months.
