Calories deficit

[Gul]

46F, 5’3”,175 lbs ( SW 201lbs) sedentary but I try lifting weights off and on and swim occasionally.Started keto 4.5 months back lost 25lbs and now stalled ( need to loose 20 more lbs)

I haven’t been very hungry,eating almost 800-1000cal/day.I have been told to eat to my BMR or I will go into slower metabolism. If I reach assigned calories I have to eat too much fat .
My carbs are less than 20 gm net and proteins. ( kind of confused on it) usually 85 gm. Rest I am left with fats that I want to keep low as it should not come from my plate but from the body to loose.
With all the advice out there I am confused on if I should eat above BMR calories or not , eat high protein or upto 60 gm optimal for women?
Will this calorie deficit stall me and hurt my body?
Need advice

But continuing to reduce calories will reduce your BMR and hamper your ability to continue to lose weight.

The other hypothesis takes into account hormonal regulation of food partititioning. Keto is based on the latter theory. The problem with the energy-expenditure hypothesis is that you need to calculate your energy intake and expenditure to within about 20 (kilo)calories a day, if you don’t want to gain (or lose) weight, and this is impossi…
