Bmi

OK, so my work is starting a new health insurance program next year that incentivizes you for staying healthy. One incentive is a $100 deposit into your medical spending account if your BMI is under 25. I'm currently around 29-30 at 6'0" 220 lbs. I have a few questions.

1. Is BMI an accurate indicator of being healthy?

2. If so, is it a reasonable goal for me to try to get under 25?

3. If so, what should I do to reduce my BMI? Is heavy lifting (which is my currect program; 70s Big) not a good fix because it will add mass?

Thanks in advance!

Re: Bmi

That is pretty cool about the incentives. I don't believe the BMI is a good indicator of health. Request if there can be an alternate metric such as BMI + waist size, excercise log etc...

FWIW I am in the same range and fall under the boderline overweight/obese category

Re: Bmi

BMI is worthless because all it considers is height and weight. Ratio of muscle mass to bodyfat isn't figured in there. It's ok for populations, but it doesn't tell much of a story for individuals.

You could be a skinny-fat 6'2" and 180lbs with 20% bodyfat and be within "healthy" BMI, or you could be built like an NFL linebacker at 6'2" 250lbs and 8% bodyfat and be "unhealthy" by BMI standards.

Mine is close to 29 - almost "obese" on the BMI scale. I definitely do not have an office body. If you looked at me, you'd probably say, "you look like you're in great shape."

When I got down to my lightest adult weight weight a few years ago (157#), I had been on a calorie deficit diet for a couple of years and my BMI was 24.6, at the highest end of "normal" and almost considered "overweight." At that time, you could see almost all of my ribs.

Re: Bmi

I wrote a post on specifically this. BMI is a problem in fit populations. Is an easy number to look at in large populations, but has serious problems.

Re: Bmi

I have nothing to add besides whats been said. I just want to post so I can be on the BMI hating train.

So... useless.

Apparently Rich Froning and Rob Orlando are morbidly obese. Huh...
