I understand where you are coming from...my BMI is 18/19. I wanted to be a certain "number in weight" but when I noticed that my body just wouldn't lose anymore, it's because my body is comfortable with how much I weigh now and if that's what it "wants to do" so be it. I used to weight 140 (female, 5'5) and got down to 108. I'm at about 115 now and that's where it stays. I almost CAN'T lose anymore. Don't stress about how much you weigh. Especially when, YES, you're actually UNDERweight. Remember that too. Worry about it, maybe, when you're in your 30s.
Hi!
Your body mass index is 19, which actually suggests that you are underweight for your height. You exercise daily and eat a generally healthy diet - it seems like you are doing all the right things! So the question is...do you really need to lose the weight...?
