Better than the BMI take the ratio of your waist to your height. Keep it a 0.5 or less.

  1. I've always had some serious issues with "BMI" measurements. For one thing, it does an extremely poor job of taking muscle mass into account. Going by BMI alone, I am at very least "over-weight," but I know this to be bollocks. At 6'2" and 200 lbs (I know, I should be using metric), with an athletic frame and heavy leg muscles (from ladders and stairs), I am not over-weight.

    But I'm sure you've heard this all before. I'm not an anomaly. Which, I suppose, only highlights how useless BMI is for a lot of people.

    According to the Waist-to-Height ratio, I am around 0.45 which is "on-par" and "healthy shape". Which is probably accurate. Unfortunately, this is also a case of confirmation bias (I am getting the result I want to get, and therefore it must be right!). Rochelle gets a 0.5.

    I think, as always, a truer measure of your body-shape-health-mass thing is to look at a number of your vitals. Which is why, of course, we go to see a professional in order to have a true physical exam. Range of motion of our major joints, heart rate at rest & under physical exertion, blood pressure at rest and under exertion, and so on.

    I look at it more like our bodies are special kinds of machines. If I walk past a turbine and all I check is the temperature of the bearings, I'm not really getting a full view of its health; I have to look at its vibrations, whether its seals are functioning properly, whether its oil contains debris or discolouration ... and so on. Obviously our bodies are even more complicated, but you get the gist.

    Anyhoo ... this ended up as a long tirade because I've long had a hate-on for the ridiculous (and bizarre to quote the article's reference) Body Mass Index measurement.

  2. Again, BMI is for populations not individuals:)

    There are lots of home tools to give you a heads up. The trusty tape measure for your waist (that's the most important one) and heart rate and sleep monitors probably to more to maintain weight than stepping on a scale (says someone who steps on a scale every day)

  3. Hah, I step on a scale from time to time, just to make sure I'm not slipping. LOL. The only way I'm failing, though, is horrendous sleep habits. I blame shift work.
