Ashleigh is right. I think you are eating too few calories. We all have a Basal Metabolic Rate, this is the amount of calories our bodies would need even if we were lying motionless in a coma. We then have to add calories that our bodies need daily just to keep us alive. The absolute minimum calories recommended is 1,200 a day for a woman. I now eat around 1,500 a day, give or take and I am losing steadily.
I did the Newcastle diet at 500 calories a day with the strict knowledge exercise and such low calories would burn visceral fat. I was taking in 9g of carbs a day, so deep in ketosis which meant I was only burning fat for fuel. I now am doing the 5:2 fast, so my weekly calories are relatively low, but not enough for my body to retain calories for fear of even leaner times. How the ND works so you do lose quite considerable amounts of weight I'm not sure, but it does, yet low calories like you are taking in, stalls weight loss in a good number of people.
My advice; up your calories to a minimum of 1,200 daily, then see how you go, keep adding in 100 increments until you start to lose, you will then know what is the right calorie intake a day for you. We are all so very different, and what works for one may not work for another, so you have to keep trying and adjusting until you find you perfect calorific intake for weight loss.
Good luck - Jo.
