Why BMI is BS

The most commonly used metric to assess body fat often labels the fittest people as overweight. Body Mass Index, or BMI, is based a math equation that is nearly two centuries old and was never intended for individuals.

The problem is BMI was drawn up at a time when people did not lift weights or regularly do strenuous sports etc.

But it was drawn up in a time where people were throwing bales of hay instead of eating doritos in front of the tv. People had much more physically demanding jobs. A few hours per week of going to the gym doesn't offset that. We don't have an epidemic of bodybuilders. And if you would actually do your research [1], you find that the data shows that BMI actually tends to *underestimate* the problem of excess fat. In other words: There are a lot more people with a normal BMI, but high body fat than there are people with a high BMI, but healthy amount of body fat.

That type of work makes you lean..... hence the rangy cattleman cliché. todays weights are designed to bulk. Check out any 60's or 70's band video and look at the almost zero leg muscles.... all razor thin legs.

Agreed.. if they want to use this measure then it definitely needs to be modified. I too have an overweight bmi yet zero waist body fat but thick muscled legs (decades of cycling) and strong back from wrestling (2 decades of wrestling)So yeah... a change is required!

It’s still accurate for today only for average people that don’t really have significant muscle mass, people that call it inaccurate because of a variable they don’t even have is stupid.

@@conbro0985 Your comment is stupid is stupid twice. Once for calling people stupid based on your one variable and two for suggesting it must be accepted, whereas intelligent people who recognize its defects would look at modifying the calculation to get a more accurate result!

The BMI also fails to take bone mass into account.

@peterselie1779 6 жыл бұрын

So you mean to tell me that your bones look like this? i.imgur.com/mYAb0EQ.png Bone only accounts for 3-5% of the weight of a healthy weight individual. That's less than 10 lbs of bone. Nobody is overweight or obese because they have a high bone mass.

When I was trying to get my CDL a few years ago I had went to this physician to get a physical done. He kept looking me over and said that my BMI was wrong and I was physically slim. I am 6ft 3in weigh 310 lb

You guys nailed it. I have suspected this for years. No perfect measurement, though? What about hydrostatic weighing? That is highly accurate . .

I’m 6’2.5” and 220 pounds At 14 years old. I play football, basketball, and tennis, and lift weights and consider myself pretty muscular in general. I also have much broader shoulders than the average 6’2.5” guy. I have a BMI of 27.9 which means I’m “nearing obesity.” So yeah don’t worry big guys, it’s full of crap. Just ask your doctor if you want a definitive answer.
