Isn't the BMI calculation for clinical obesity-the biggest load of tosh ever dreamt up by the diet industry?

Pretty much. I have a healthy BMI and body fat level, but I'm sure there are plenty of people who are being misclassified by BMI.

HTH : )

when I saw it , Thought there is no possible way I can get down to the weight they set on the new one =I'm with you on this one
I am confused, what is bad about it? You are the first person I have ever heard saying its not a useful tool.

Perhaps you just feel bad because now there is an acutal calculation that tells you you are fat...not just a person's opinion...
Absolutely. It does not take into account how much muscle a person has. So, if someone has a lot of muscle& barely any fat, they can still be called "obese" when they are not ,according to BMI. (due to muscle weighing more than fat) Example:
If you have 2 females & both are 5'5" & weigh 180 lbs.

Female #1 does not diet & the only exercise she gets is putting Big Macs in her mouth
Female #2 is a body-builder

According to BMI, both would be "obese" when person #2 doesn't have an ounce of fat on her.

Not only is the concept flawed, but, it is one of the causes that makes girls think they are fat ( & cause eating disorders) when they are not....just have more muscles than they think.
i totally agree with you. i have met thin people who were unhealthy and larger people who were very healthy. i think genetics play a big part of how much we are to weigh. also, hormones and medical reasons keep some people at a certain weight. i have pcos and it takes everything i have to keep my weight where it is and i still get hassled. i think as a society we feel if a person is overweight that means they are lazy and eat all the time and i beg to differ. sure, there are the ones who eat and don't do anything but, don't assume that everyone is like that.
BMI is a guideline that is reasonably accurate for the
"average person", but not for all.
For example, I am 5'8" tall and weigh 210 lbs. According
to the diet industry, with a "large frame" I should weigh
no more than 174 lbs. I am clinically obese, right?
Perhaps clinically, but in reality, I am muscular, with a
large frame and perhaps 5 pounds overweight.
So yes, it certainly can be a "load of tosh" or even
a"crock of sh*t", But I actually get a kick out of telling people that I am obese.
Take it with a grain of salt. The best way to know if
you're obese is to look in a mirror.
