Hello Monica and welcome to the forum.
Well done on your weightloss so far a good effort.
I also agree you don't want to go below 1200 cals per day. The other thing to look at is how much exercise you are doing. I used to have around 1200 cals when I first started out losing weight and as I started to ramp up the exercise I found myself getting hungry and increased it to 1450 approx per day. Your body does actually become quite efficient at burning the extra cals if you are exercising regularly, and works even better if the energy in is of good quality.
It all takes a bit of trial and error but stick with it and you will get to your goal.
All the best and let us know how you go.
