My allowance is 1570 cals, I also find it very hard. I've currently got into a routine where I am doing ok, but only by carefully planning snacks as well as meals.
I have the same for breakfast every day:
Baked oats, 100g Greek full fat yogurt, raspberries and blueberries
125ml milk in tea throughout the day or black coffee
Lunch is either a rice/prawn/veg mix with soy sauce and lime or a sweet potato curry with chicken, I batch cooked these a week ago and made 6 portions of each, and I have a veg bag steamed with it. Maybe a fruit or sugar free jelly
Dinner yesterday was a chicken curry, no rice or today was baked potato and tuna. I cook from scratch every night, aim for 500 ish calories
Snacks- rice cakes with cream cheese, pop works chips, fruit, carrot sticks and hummus. (I've planned in 2 snacks each day)
Totals around 1560-1600 each day.
It's hard though, and there's no room for any extras, or alcohol. Any less and I get too ravenous and end up bingeing.
