@mu_t:  the best example is Dwyane “The Rock” Johnson and why BMI doesn’t consider all factors.  The Rock, due to his height and weight, is considered morbidly obese if you typed in his numbers to a BMI calculator.

I think BMI is a good tool to use as a guideline.  I do not think it is the one and only way to indicate how healthy someone is.

I am technically overweight right now, but I am on MyFitnessPal and working to eat better.  Once I meet some of my nutritional goals I’ll start exercising more and hopefully I’ll be within a healthy range by spring 🙂

Some people are considered overweight because they have a higher percentage of muscle.  Muscle is much denser than fat (it doesn’t weigh more… a pound is a pound is a pound!)  A pound of fat takes up a LOT more space than a pound of muscle!

Some people have a thicker bone structure, so no matter how hard you try you may always have a higher BMI but you can still be healthy… like eat well, be strong and active, have good endurance, etc.

I think overall it’s a pretty good indicator because most people in the US don’t fit into that weight-lifter categeory.  The government, doctors, schools can use it as a general guideline and it probably works for a majority of people.  Which is why they use it.  But yeah, it doesn’t necessarily work with everyone.  If you’re carrying a lot of muscle (muscle weighs more than fat too) it can be inaccurate.  It’s maybe best used as a screening tool but not a diagnostic tool.

@mu_t:  I think the most accurate way is to measure body fat percentages, but that usually requires tools/lots of measuring.  I think BMI tends to favor short people.

@mu_t:  honestly, I’m 5’4 and when I was 118lbs I was considered overweight on some charts.  If you saw me, you would swear I was anorexic or had an eating disorder.  Because of my natural body shape I look sick at that weight.  I naturally have a larger chest and hips/thighs.  When I’m that small, my hip bones protrude, and my collar bones are extremely prominent.  My face also gets thin very quickly when I lose weight so my cheeks will hollow and I look ill. 

135 is the weight that feels comfortable and looks healthy.  I’m not saying that BMI’s are wrong, but I think that everyone is different and you need to be the size that is healthy and happy for you!

@housebee:  Yeah, body fat percentages are great!  But you need special equipment for that so I can understand why the government uses BMI as a tool everywhere (no special equipment needed).

@mu_t:  If you lift weights, IGNORE IT.  I’m considered obese and I’m not.  I’ve lost 20 pounds since our wedding and it still has me at obese.


It’s a good guide if you’re changing your diet to lose weight.  Remember, it takes time and even slow progress is progress!  This is my favorite and I think about it ALL the time:

@mu_t:  I don’t trust it. It tells me I’m underweight, but 1) It’s not like I starve myself. I haven’t gained or lost weight for almost 10 years. 2) My doctor has never said ANYTHING to me about my weight. Never once told me I need to gain weight or anything. Never commented at all, always says I’m healthy. 

So I don’t take it seriously. Although, I know how you feel. I would give anything for it to tell me I’m at a healthy weight. I’m hoping to gain some pounds that I can keep when I get pregnant.

I’d say you are a bit overweight for your height (as am I currently.. I have similar stats to yours and I’ve definitely been a lot slimmer in my adult life), but no, BMI isn’t the be-all and end-all. Mind you, I’m no expert on this. If you have a more muscular frame then you’ll likely be towards the end of the healthy ranges even if you’re a pro athlete.

@mu_t:  Honestly, I totally would if I could!
