I dont know, I see a lot of teenagers on here talking about losing weight when they turn sideways and they disappear.
I see alot of girls who have a BMI of 20 wanting to lose to a BMI of 18 or something ridiculous. I can see if its a BMI of 20 and maybe like...5 pounds depending on your height, but anything over 10 is asking for failure and a disorder waiting to happen.
I honestly don't think it's their faults. Society has basically lured many teenaged girls into thinking a BMI of like 17 is 'perfect' and 'thin' and they just sort of... fall into it. Along with low self esteem. I actually pity them :/
