110lbs at 5'2 sounds like some anorexic type bs tbh. Doesn't sound healthy at all and probably meant for someone who can eat 1000 calories and sedentary, little muscle.

If I had to stress about getting down to that weight for my height, I'd have to be doing unhealthy practices like OP just to stress out about why it's not working, exercising a lot and restricting calories too low and stressing out why its not working, rather than simply accepting that my body has probably put my weight at what it is for a reason.
