Struggle on recommended cals when tracking always starving

I’m 44 and currently attempting to lose 2-3 kgs. But I struggle on the recommended 1400 cals and lower that my app suggests. I use your lifting program 3 days a week and do 1 cardio session plus 1 CrossFit and take 2 days off. How can I meet my cal goal Without being starving all the time? I think being in perimenopause doesn’t help maybe? I’m on ALL the HRT 🤣 I eat well, don’t skip carbs and hit my protein goals. But I’m not moving from 65kg and it’s driving me Crazy! Any tips please ?
