Fast 800 is very hard but does work.
Low calorie low carb is very hard, also work.
I'm not a medical professional but I lost weight low carbing.
I need to eat low sugar low carb but I don't know what this means.
It's meat, seafood, nuts, seeds, eggs, green vegs and full fat dairy like hard cheese, butter and cream.
No potatoes, carrots, beets, milk, beans or lentils (unless vegetarian or vegan), pasta, rice, couscous, sugar, fruit (berries are low in sugar but it's best to be avoided initially and then only a small handful if you must).

Some places I've read I need to eat high fat dairy, some places say no dairy at all.
This is down to your body and if you feel fine eating cheese and cream or not. Sometimes people's weight stall if they eat too much dairy because let's face it cheese is delicious. Some people eat dairy and have no issues. You can start with eating dairy and see how you get on.
Gluten free or no bread at all?
Gluten free is a different story. You can be low or high carb and gluten free. This is something for a digestive issue or autoimmune. For PCOS you need to go further than excluding gluten. There is low carb bread and bread substitutes that are low carb. But the regular bread? Nope.
I have two young children and a husband. I work, life is busy, I don't have a huge grocery budget and I can't make different food for everybody.
You're going to have to prioritize your health and make adaptations. You are worth the cost. If you're ill you wouldn't be able to cook much and your grocery will be even higher on convenience food. In time, you won't be so hungry and you might find you eat 2 or even 1 meal a day so don't be discouraged. Low carb if done right really suppresses hunger.
I would do things like, eggs for me and my husband but he would also have toast. My children might just have toast.
If we're having English breakfast I'd skip the toast and hashbrowns.
If I make a chicken curry, I give them rice and I either eat cauliflower rice or just the curry on its own.
If I make bolognese, they eat it with spaghetti and I eat it with courgetti or some shredded cabbage.
Sunday roast, they have the potatoes and yorkshire pudding and I have meat and veg.
Family having wraps? I wrap my filling in lettuce or eat it as it is maybe with extra green veg. There are low carb wraps.
There are many ways of making your favourite food low carb and loads of recipes online.
I also find eating this way is expensive so I end up eating wrong food because its quicker and cheaper.
I find initially like the first 10 days or so I eat a lot but once I'm in ketosis I don't eat as much and my grocery bill is cheaper because I'm not buying chocolate, cakes, crisps, takeaways and wine!
Use your instapot or slowcooker if you have them. Menu plan and get the ingredients. Prepare food like tuna mayo in a tub, boiled eggs in a tupperware that kind of thing. Get some convenience products like frozen broccoli, prewashed salad leaves, low carb salad dressings, and pork puffs (not scratchings, these fuckers will break your teeth!), almond butter (it has no sugar but somehow tastes sweet!)
Any change is hard initially remember, nothing changes if nothing changes. Your health is worth than extra time and initial cost because trust me, it's not cheap when you're ill!
I wouldn't get bogged down with calories initially and would focus one eating what is on the allowed list until I'm in ketosis and then I'd look at my calories if my weight loss has stalled. Even though I believe calories matter, it's just too much all at once.
