Why are you restricting yourself to 1000 calories a day? It doesn’t sound sustainable to me.
I’ve been in a calorie deficit since 1st June, averaging 1400 cals a day. This allows little treats like a couple of squares of dark chocolate and decent sized portions so I don’t feel deprived.
im eating good food like poached egg on toast for breakfast, a jacket potato with beans and cheese and a side salad for lunch, spag bol, veggie chilli with nachos and rice, sausage a mash, a roast etc for dinner.
fwiw I am 5’4, SW 10st 8 (1lb into the overweight category) and I’ve lost over a stone. (Approx 1-2lb a week).
