Every one is so different in terms of bone frame size (which never changes regardless of weight as an adult), density of muscles, etc. and how that translates into weight.

I have a good friend, she's shorter than you at 4'11" and I believe she told me 2 months ago when I saw her, she's close to 110 lbs. She is more petite than I (5'1", I'm at 100 lbs.) and she is slim but sturdier than I. ...she cycle-tours, cycle commutes, hikes and plays tennis several times per week year-round. She also does strength training (which I don't do myself). She is 54-55 yrs. (I'm forgetting here....)

Aside from your weight on the scale, have you noticed any changes in how you fit your clothing now?

as for feeling hungry ...maybe is to eat well and healthy at least for breakfast and lunch so that your energy doesn't tank and ease up on dinner to meet the 1500 calories.

what changes in diet in terms of what you eat have your tried where you are eating more of to compensate for energy need but to lose weight?
