You don’t “need” to eat breakfast at all, it completely depends on the person some people find if they eat breakfast it opens the floodgates so to speak and they are hungry from then on. Also if your not hungry at breakfast why eat for the sake of it? IF you are hungry and want to eat breakfast then porridge is a good choice or eggs
Lunch
Eggs (anyway you like, boiled, scrambled, omelette)
Soup
Salad with chicken/tuna/eggs
Even a sandwich is perfectly fine (although not everyday) just put some salad in it as well
Beans on toast
Dinner (always have a pile of veg or salad with every dinner)
Cod (spoon of pesto on top, then oven bake) with sweet potato wedges or mash & veg
Chilli, have with broccoli rice instead of normal rice sometimes
Steak/chicken/turkey with salad or a huge pile of veg
Chicken/steak & veg stir fry
Burger (no bun) with sweet potato chips & salad

Snacks

Do you drink tea/coffee? If so do you have sugar? Start reducing the sugar 1/2 a spoon every few days if you do
Drink enough water because it helps you feel “full” start every morning with 1-2 glasses and drink more during the day
Limit alcohol because it is calories! I only have a drink at weekends unless it’s a special occasion
