If there's one thing I would change about medicine it'd be to abolish the BMI. It's bad science.

We now know that your weight is not a health risk. Smoking, eating shit food, inactivity: those are the health risks.

Lots of thin people are inactive, crap eating smokers.
There are very healthy fat people.

They're are extremely unhealthy thin people.

We know this. We have the data. We have to stop judging people's health by looking at them. It doesn't work.
There's nothing wrong with being fat.

There's nothing wetting with being thin.

The problem is sedentary lives. So many jobs keep us still. Exercise is expensive and hard to find time for.

The availability and affordability of healthy food. Shit food is plentiful and cheap.

However, it's not just a matter of shitty doctors.

Fatphobia and the belief that fat=unhealthy is baked deep into our society. We have to change that.

It will be about as easy as getting rid of racism.
Indeed. Though many argue that is not applicable for larger populations either because fat is not a health indicator.

Yes. Getting healthy is prohibitively expensive.
The above tweet was in response to this tweet:
Lots of Twitter fail from me this am. Ugh.
If we really wanted a healthy society, we would subsidise healthy food, exercise programs and quit smoking programs for everyone.

We'd eliminate food deserts. Provide free childcare. Subsidise mental health support.

Instead of wasting billions on policing fat.
Yup. All the research I've found utterly refutes BMI. Including folks in the underweight and lower "normal" categories having the worst health outcomes.

I'm blocking the fatphobes responding to this thread. Life's too short for their nastiness.
I'm seeing several of you point to waist measurement as proof that fat is a health indicator.

Nope. That's about fat distribution.

There are folks in the underweight and normal weight BMI categories with pot bellies.
Factors that effect how much you weigh and thus how accurate BMI is:

The size and density of your bones

How much muscle you have--muscle weighs more than fat

The density of your breast tissue.

There are many, many reasons BMI is hooey.
For the "exercise need not be expensive" crowd.

For many in the USA, covering rent & food etc means holding down multiple jobs. They literally don't have time for exercise.

Many people can't go for walks because they don't have time & live in neighbourhoods without sidewalks.
There are vast swathes of the USA where you can't go for a walk without taking your life in your hands.

No sidewalks and barely a shoulder. Cars go zooming by and you just pray they don't hit you.
In the USA the neighbourhoods with sidewalks and parks etc--the walkable neighbourhoods--are expensive to live in.

So, no, that walk you're going on is not actually cheap.
Yup. Street harassment is quite the price to pay for free exercise.

I'm going to mute this as my mentions are a trash fire.

I'll leave you with this summary of some of the research I'm talking about, via @anniebellet.

I would love it if some of you fatphobes would actually read it : nutritionj.biomedcentral.com/articles/10.11…
