What is your target calorie range?
Each person can be significantly different. I recommned working with your nutritionist. I was arouond 600 and she said I was not eating enough, which is why my weight loss was so slow. She had me bump it up to 1000 (with 100 g carbs and 25 fiber). I am going to trust her and see how it goes for one month. I will say it broke my stall and I lost 3.8 this past week. But like I said, I highly recommend working with a nutritionist that is trained to help with this sort of thing. There are a lot of good vets on this site as well that can say what worked for them. It is all a guessing game until you find what works best for you.
