The Case Against BMI

I shared on my Facebook page several days ago an article from my local newspaper about how South Carolina had become the 7th fattest state in the nation.  Before I even clicked the link to read it, I went into orbit. Because I knew that the entire "study" would be based on the outdated, worthless statistic known as BMI.

What is BMI?

BMI stands for Body Mass Index. Here is the definition, straight from the Centers for Disease Control and Prevention's website:

"Body Mass Index (BMI) is a number calculated from a person's weight and height. BMI is a fairly reliable indicator of body fatness for most people."

Allow me to share my own definition: "Body Mass Index (BMI) is a worthless number calculated from a person's weight and height. It is an unreliable indicator that is so insane and unrealistic, its very existence contributes to an unhealthy body image and serves no purpose."

To illustrate what I am talking about, I will use myself as an example.  I am just under 5' 8" tall and weigh 199.5 pounds. What says BMI and the government about my weight?  Let's visit the online BMI calculator, again courtesy of the Centers for Disease Control and Prevention:

I have lost going on 400 pounds and have people telling me I look too thin.  Yet according to the dunces at the CDC, I am still "obese."  Furthermore, I need to lose 35 pounds to achieve a BMI of 24.9, so I will no longer be "overweight."  The stupidity is breathtaking, isn't it?

If I lose 35 more pounds,  I would be malnourished and probably scare small children at the store.  This is why BMI is idiotic and useless. Here's the truth about BMI: I am not obese, this chart is unrealistic and stupid and anyone who uses it as a guide is dumb. Perhaps the saddest casualty of BMI as a measuring stick for weight is someone's body image.

When I weighed 577 pounds, I used to look at the BMI calculator. 164 pounds! That's impossible.  At my highest weight, my head probably weighed 164 pounds.  So I just gave up.  BMI causes people to strive for unattainable perfection.  The message is clear: unless you're in the normal range, you're a failure and a terrible person. You're fat.  BMI has the same effect as a fashion magazine with a Photoshopped supermodel on the front of it.  It contributes to an unhealthy body image and causes eating disorders.  BMI is dangerous and destructive.

Who are you calling "obese?"




It turns out I am not the only one who is starting to realize this.  Researchers are finally beginning to accept that BMI is useless as well.

So what is the solution?  I have it right here, right now...and I will tell you for free (lucky you.)  Here it comes....wait for it...wait for it....wait for it....

Common sense. 

Blasphemy! Shocking! How dare I?

Here's how doctors should decide if someone is overweight or not: look at the person.  Look at their history.  Encourage them.  "If you would just get 50 pounds off your knees, it would make a difference."  In other words, if you weigh 500 pounds, 450 is better.  300 would be a fantastic goal. Stop striving for perfection.

And here is the ultimate indictment of BMI: the more society uses it, the fatter we all get.  It simply has no place in our society and is absolutely not part of any solution to our weight problem.

BMI sucks. End of story.

Another Milestone: Below 200

Yesterday was a great day.

It was time for my monthly weigh-in, but I had put it off a few days for superstitious reasons. I really wasn't sure what the scale would say.

People who lose large amounts of weight experience what I like to call "fat paranoia."  This is a condition with no known cure.  Despite all the overwhelming evidence, you become convinced you are getting fatter. The shirt becomes a little more snug. The pants are tighter. "I'm getting bigger, I just know it."  The mind plays tricks on you like that.

So finally I decided enough was enough and I was going to face the music. If it was a few pounds more, I was not going to overreact. I would just exercise more. Tighten up the portions.  I weigh on an old-fashioned balance beam scale, the kind you find at most doctor's offices. These are the most accurate. Digital scales are very inaccurate, I have found.

For more than a year, the large bottom weight was on 200. I slid the top weight all the way to zero and the beam still did not rise.

It was time to move the bottom weight to 150. I couldn't believe my eyes. The scale balanced between 199 and 200.

I finally did it. I was under 200. I couldn't believe it. After all this time, here I was. I remember for years thinking how ecstatic and satisfied I would be to just get under 400. Under 300. Around 250. Anything.

But under 200? It didn't seem possible. Everything I had ever been told by the naysayers wasn't true. I'm not starving. I'm not "too skinny" (at least I don't think so) and loose skin is not hanging off of me to the point that it's a problem.

But I do know one thing: this is not the end, this is just the beginning. When you reach the end of the weight loss rainbow like I have, nothing has been achieved. I can't just sit back and be satisfied with what I have accomplished.  I now have to maintain it. I must do exactly what I have been doing for the last 3 years, 2 months and 4 days. Because if I don't, the weight will come back. All of it, plus more.

I don't often celebrate anything having to do with my weight loss, but for now, I will say...here's to getting under 200!
