So here’s a gut kicker that happened to me today. Regularly, I go to my general practitioner for a med check and I for the most part I request that they don’t check my weight. As much as I talk about how the number on the scale isn’t necessarily an accurate indicator of one’s health and definitely not a definition of one’s worth – there are times when that number grabs a hold of my self esteem and drags it down a few notches.
I received an invitation to my GP’s medical website that has all of my health information and records. As I logged in, guess what was the first thing I saw? My weight. The second thing? That it was classified as obese. My files show one of my diagnosis is Obesity. I know I have gained some weight in the past year –and it hasn’t been from strength training. The past year definitely knocked me on my butt emotionally and I am no different than many others out there — I wasn’t interested in being diligent in what I was eating and eating crap made me feel better – at least at that moment in time. But.. even with that – there is no way I am obese. Intellectually I know this — even with my admission that I could stand to lose some poundage-I am not obese.
Even that pod test I did earlier this year didn’t put me at obese.
As I work to beat down the blow to my self esteem, it bears repeating that BMI is not a good indicator of health or a healthy weight — “We’re battering a ram into a brick wall trying to measure success through people’s BMI.”
Seeing that word OBESITY in black and white has added to the blah feelings that have been hovering over me lately. I’m exercising just as usual –maybe even at a higher intensity so I know that I have to put the focus on my nutrition. But knowing what I need to do – and doing it are two different things. I have to figure out what’s going on my head first — and I know it will click.
During yesterday’s hot yoga class, the theme was practicing compassion -specifically SELF COMPASSION. Often times we are so hard on ourselves, never cutting ourselves a break. Kindness needs to start with you in order for it to really blossom. We all have disappointments, struggles that we deal with and visions of how we think things should be — but sometimes the reality doesn’t or just can’t line up. We want to look a certain way or be better at something we try and set up these unrealistic expectations and then are so mean to ourselves when it doesn’t happen. Challenge yourself to stop those voices in your head that automatically shoot you down — and practice self compassion daily.
One of the guys I workout with in the AM, Ray, shared his experience when he went in for a physical this week:
Doctor at my physical today told me that because of my BMI number he thinks i am OVER WEIGHT, even though the nurse did my body fat percent which was 11.4%.
It’s another example of what a crock of crap BMI is —

I personally was not a fan of the BMI measurement scale. 2 people can have completely different body shapes and and weigh the same — and one comes out as obese based on weight alone. There are way too many variables to add to make it that simple in my opinion.
Scientists have developed a new way to measure whether a person is too fat without having people step on the scale.
The new measure, called the Body Adiposity Index, or BAI, relies on height and hip measurements, and it is meant to offer a more flexible alternative to body mass index, or BMI, a ratio of height and weight, U.S. researchers said on Thursday.
BMI has been used to measure body fat for the past 200 years, but it is not without flaws, Richard Bergman of the University of Southern California, Los Angeles, and colleagues wrote in the journal Obesity.
While there are other, more complex ways to measure body fat beyond simply stepping on a scale, BMI is widely used both by researchers and doctors.
It is calculated by dividing weight in kilograms by height in meters squared. A person who is 5 feet 5 inches tall is classified as overweight at 150 pounds (68 kg) and obese at 180 pounds (82 kg).
But there is a lot of wiggle room in that calculation.
For example, women and men with the same BMI might have very different levels of extra flab. BMI numbers cannot be generalized across different ethnic groups or used with athletes, who have extra lean body mass.
The team made the index using data from a Mexican-American population study. They confirmed the scale’s accuracy using an advanced device called a dual-energy X-ray absorption or DEXA scanner. Tests in a study of African Americans showed similar findings, suggesting BAI can be used across different racial groups.
BAI is a complex ratio of hip circumference to height that can be calculated by doctors or nurses with a computer or calculator.
The team says BAI still needs some fine tuning, and they still need to test it among whites and other ethnic groups, but they think it has promise as new tool, especially in remote settings with limited access to reliable scales.
“After further validation, this measure can be proposed as a useful measure of percent fat, which is very easy to obtain. However, it remains to be seen if the BAI is a more useful predictor of health outcome, in both males and females, than other indexes of body adiposity, including the BMI itself,” the team wrote.
Obesity has become a global epidemic, with more than half a billion people, or one in 10 adults worldwide, considered to be obese – more than double the number in 1980. Obesity-related diseases account for nearly 10 percent of U.S. medical spending, or an estimated $147 billion a year.
Obesity is the latest health woe being blamed for low sperm counts among men of child-rearing age,

Maybe, at least according to a study on 2,157 young men published in this month’s Fertility and Sterility.
Men with higher body mass indexes also had lower sperm counts, although still within the normal range. And BMI doesn’t necessarily offer an accurate indicator of body fat levels — although previous studies have already found a link between men’s body fat distribution and poor semen quality.
Based on the results, Oreopoulos found that 41 per cent of her study group had been wrongly classified by BMI. Some patients who had high body weight but lower body fat were mistakenly considered obese, and conversely, patients of low weight and high body fat were often labelled as normal.
“What it showed is BMI doesn’t really mean much. It’s not a good measure of risk,” she said.
