I wanna loose weight 47 kgs and am 157.5?

Noooo I just calculated you BMI (body max index) youre 19.1 which means youre underweight!! You're ideal weight is actually 5 kilograms more than you are now. Don't obsess about your weight, Ive been there and it only got so bad I ended up with bulemia which now, 6 years later makes me have horrible acid reflux and stomach issues. Weight loss can seriously go to your head!! Don't let it!
