I met with a nutrionist last Friday. She measured me at 5'7 and a quarter inches. I have a large bone structure: even if I were to lose a lot of weight, I'd never be one of the petite skinny beauties. Its just not going to happen.
According to the BMI Chart, I should weigh NO MORE THAN 155 pounds. The nutrionist looked at me and laughed, seriously. I thought that it seemed really off, because even prior to my endocrine disorder hitting full force I never weighed less than 180 as an adult. And that was being on the varsity volleyball team and walking almost everywhere because I didn't have a driver's license/car.
The nutrionist said that I would look emaciated if I weighed 155 pounds. She felt an ultimate goal for me would, in fact, be 180. That puts me in the borderline obese (right on the line of overweight versus obese).
She then said that the BMI chart does NOT take into account muscle, bone structure, etc.
I lift weights, and I swim at least 3/4 of a mile daily. I don't lose weight quickly (or frequently AT ALL). I might lose 3 pounds in 6 months. Its taken me 3 years (since I was diagnosed in late 2001) to stop gaining weight, and lose 70 pounds. That is with DAILY exercise of 1 hour or more, 5-6 days per week, and carefully watching my caloric intake as well as the constant attention of a gastroenterologist, endocrinologist, and now a nutrionist, plus the people I work with at the gym. And this is just me.
My best friend is probably 5'4" tall. HER upper weight limit is 130. She hasn't weighed less than that in most of her adult life, and when she did it was because she was a dance minor in college. Yet, you'd NEVER call her obese. She & her husband do yoga and tai-chi, plus walk long distances 2-3 times per week (and I mean LONG distances: 10 miles or more).
I think the BMI chart is a load of cow manure, personally. Its a way for people to say that we have yet another crisis. There are so many things it doesn't take into account. I wouldn't use it to set a goal weight. And I don't use it to tell me whether or not I'm healthy. A government chart can't do that, because that chart doesn't know what I do daily.
