So if you surfed the internet at all yesterday, you may have come across an article with the title, “A Few Extra Pounds Might Bring Extra Years.” In fact, if you Google that title, you’ll see the article all over the place. Seems to be a hot story.
If you didn’t see the article, Click Here to read it.
I also dug up the abstract of the research.
I worry about articles with titles like that. How many times do we just scan headlines and titles without reading the articles. Millions of people do this. If you’re one of them, you might get the wrong idea that if you weigh more, you’ll live longer. However, the article was quick to point out that the findings do not mean that normal-weight people should try to pack on extra pounds, the researchers said.
Anyway, the gist of the article said that if you were underweight or obese, according to BMI measurements, then you will have a shorter lifespan and that if you are overweight, you will live longer than a normal weight problem. The problem is #1 that there have been other studies stating that if you were overweight, that this could lead to premature death, which is in direct conflict to this study.
And secondly, they used the measurement of BMI, or body mass index, to classify whether a person is underweight, overweight, normal weight or obese. I can’t believe that research which still use BMI as a measurement still exist. BMI is a measure of height to weight and is an inaccurate way of determining whether a person is overweight or not.
Overweight using BMI is defined as someone who has a BMI between 25-30. So a 5’10″ man weighing 181 pounds has a BMI of 26 and is considered overweight. In reality, this person may have lots of lean muscle and have a body fat % of 8 percent. That man is not overweight in reality. This is where the results of any study using BMI can be skewed.
So what is a better measurement? I believe that taking your waist circumference using a tape measure of even finding your waist to hip circumference ratio, again using a tape measure, will give you a better predictor of heart disease, heart attacks and other obesity related ailments. If you’re a woman, the waist-to-hip ratio should come out as no more than 0.8. Men have a little more wiggle room: a healthy waist-to-hip ratio for them is 0.95.
This means, if your belly has bulged out enough to catch up to the size of your hips, you should start worrying about your heart, experts say.
I would love to hear your thoughts about this research article that just came out. Please leave your comments in the comment section.
Have a great day!

The waist/hip ratio is a new one to me. Thank you for that. I would have thought body fat would also be an important number.

Ya, BMI is bogus really. I went for a physical as required by the health insurance company, I signed up a new policy. My risk factor was high because my BMI was high. Did they bother to measure my waist? Nope, 32.5"…
I had to go to one of their doctors for a re-appraisal. At the office, the doctor walked out and called my name. When I got up, he called my name again, looking around. I guess he expected a very heavy mid-section person. Once I convinced him I was that person, he signed the papers and let me go home!

Is it fair to suck in one's belly when measuring? lol

I am 6'0," 253 lbs, 12% BF. Waist to hip measurement means nothing to me.
I found a scale that used height, waist and weight to find BF, it was very accurate; for woman it used a slightly different configuration with waist and hip ratio.
The last time I used BMI it said I was obese or on staroids, (LOL)!
No, I am not on steroids, I do not take suppliments; rarely I use creatin and weigh protien, 2 months with, 4 months without. Did I mention, I have a broken neck and I am on the brain and spinal cord registry for Florida… If you believe, you can achieve!.

I totally agree that BMI is not representative, particularly for people with a lot of muscle – have to play with the waist/hip ration – sounds interesting

I believe you have said is correct. BMI's are bogus. Just because one may be heavier than the ideal weight based on height, it doesn't mean one is fat – it could be muscles gained.

I can't believe someone would even fund a study where the data is so pointless in determining anything. My partner and I are roughly the same height (he is about 2-3cm taller) but he has 22kg of muscle on me. But his BMI index is 26.4 and mine is 20.4. Is crazy, how irrelevant this measurement is.
Even comparing females, breast weight between someone who is an A and someone who is a D could possibly categorize 2 women of the same basic health and height as one being overweight and one normal.

Abstracts usually only pick research that backs their hypothesis (see Joel Marion's defence of Aspartame- even then he hedged by recommending only one "soda"/ day).
Go with what feels good for YOU and eat healthy and you will lead a healthy lifestyle.
There is NO way in the world that John Candy could have ever dieted and exercised his way to look like Arnie!
Just be the best that YOU can be.

Here's a link to an article that states also the hip/waist ratio is as far as we know not a good predictor based on research:

I'm not saying stuff yourself…extra weight still is heavy on the joints and junk food is lacking in vitamins it won't make you feel good. But it seems weight/bodyfat in epidemiological studies is not a great predictor of health/longevity as far as we currently know.

BMI does not work for athletic people at all. WHR is better for young adults like Scott, but needs adjustment for older people. It is unrealistic to think that an older man or woman should keep the same WHR as when they were younger. Any reliable index should include age and some measure of athletic condition (Body Fat %?).
Regardless of measurements used, I think the study has some merit about how being too thin is not healthy. The news about Michael Jackson's death yesterday makes me think about this. Although he seemed to be aerobically active in dance, he also always seemed rather frail to me. Heart attack at 50? Not what we all hope for in life.
