For what reasons was the BMI calculator even invented?

For studies: In order to study obesity, one has to have a definition of what it means to be obese. You can't simply use weight, as 200 lb might be obese for some people but would be a thin person if their height was 6 ft 8 in. Bmi takes into account height and weight. A bmi over 30 is considered obese. ...Read more

For most of us, the bmi is a good indicator of appropriate weight versus overweight. ...Read more

Could somebody be anorexic but have a normal bmi?

Could somebody be anorexic but have a normal bmi?

It's a mindset: While the majority of people with anorexia will be underweight, some to dangerous degrees, anorexia is more about the mindset that one's actual body weight. The mindset results in the underweight state, or the perception of an underweight state, or the need to have more control over your weight. So yes, you could think anorexic without actually being physically underweight. ...Read more

I have a BMI of 16.0 and I think it's alright but apparently anything under 17 is considered anorexic. How can I get that extra 1 bmi?

Says who?: You're anorexic if you have inappropriate thoughts and behaviors about food. The bmi was not developed for individuals and shouldn't replace common sense. John cena is not "obese" and many elite runners are "underweight". Almost all men and most women want some muscle for which you can do resistance training, but the key here is staying fit ; your weight will take care of itself. ...Read more

I am gaining weight after anorexia for the past month (BMI reaching 17 after being at 15). Any chance I could build up muscle? If so, how can I do it?

Requires using them: Muscle cells respond to both intensity & frequency of use. Without use they atrophy away as in polio victims (Polio virus damages nerves, not muscles). But if muscles get no nerve orders they rarely contract & waste away. Thus focus on all opportunities to use muscles to do actions which require/challenge your strength, hopefully without overdoing & creating damage. Athletes say: No Pain, No Gain. ...Read more

Relapsed w/ purging anorexia 6/21&22. See psychiatrist in 3 weeks & should tell him; but I don't want to stop. What will happen if I tell him? Bmi = 24.

Anorexia: I think you would feel better if you saw a mental health professional weekly for psychoterapy in addition to psychiatrist. It is common to not want to stop but think of this compulsion as an addiction that will compromise your life drastically if you continue. A clinical psychologist experienced in treating eating disorders could help you greatly. Best wishes. ...Read more
