The NHS defines it as a way to calculate your healthy weight, a way to measure your weight compared to your height. The calculation tells you whether you’re underweight, healthy, overweight or obese.

This is a chart detailing the bullshit:


Let me hit you with some juicy truth nuggets:

The BMI was introduced in the early 19th century by a Belgian named Lambert Adolphe Jacques Quetelet. He was a mathematician, not a physician. I am pretty confident that the general population’s average sizes and lifestyles have changed since the 19th Century. For example, 1830 the average height for a woman was 5’1’’ and 5’5’’ for a man.

BMI ignores bone, muscle and waist size. So a large rugby player with larger muscles or bones could measure obese on the BMI scale.

It ignores body fat percentage

It doesn’t take gender into account. Women have higher body fat percentage than men. We need more body fat to regulate our hormones and have babies! We actually NEED that junk in the trunk.

Doctors seem to rely on BMI which means they are less likely to use scientific methods that are available. (Probably because it would cost the NHS more money)

In 2016, a study by UCLA concluded that tens of millions of people who had overweight and obese BMI scores were in fact perfectly healthy.

But they also found that 30 per cent of people with “healthy” BMIs were in fact not healthy at all based on their other health data.

In 1997, a decision was made by nine experts from the US National Institutes of Health to reduce the max healthy weight range from 27.8 to 25. Megan Crabbe pointed out in her book “Body Positive Power” that 8 of these 9 professionals have ties to the multi-billion dollar weight loss industry. Meaning that 39 million Americans became overweight overnight according to BMI!

This whole “one size fits all” shouldn’t be adopted by Doctors, someone’s general health should be based on each person individually. A person’s health should not be measured simply by a number on a chart! I am not completely dismissing the use of BMI, I am sure that it has some good uses?

From my own experience, BMI has become what Doctors RELY on. I went to the doctors THREE times whilst I was underweight (according to my BMI.) Because I was very lean and had large muscle percentage, my BMI wasn’t LOW ENOUGH for them to even consider that I had an Eating Disorder. They didn’t measure my body fat, they had no idea that it was dangerously low at 8%. (Women need essential fat between 10-13%)

My Doctor said my periods should come back when I am at a healthy weight. So I asked them, what weight would that be then? Out came the fucking calculator.

I believe that MY BODY will decide when I am a healthy weight. So maybe that would be when my periods return and my body fat percentage and hormones return to normal, THEN I think I can be considered to have a healthy BODY rather than a “healthy weight”.

So because of my height, I need to hit Xkg to be considered healthy?

Bitch please, I don’t need a number to tell me when my body is rockin’.
