Why do people keep making this argument? It's a terrible argument. BMI and body fat are extremely strongly correlated. People with a very high BMI are all obese or morbidly obese. And people with a very low BMI are almost all underweight. BMI is a very simple, easy to calculate and useful metric. It works across countries and across time. BMI is just one metric. It doesn't tell you everything and knowing only the BMI…

> People with a very high BMI are all obese or morbidly obese. That is tautological - obesity is defined in terms of BMI. BMI over 30 is obese. Arnold Schwarzenegger is 6'2" and weighed 235lbs at contest (30.2 BMI) and 260lbs in the off season (33.4 BMI). So much for your "all" claim.

I feel like we're in the dark ages with nutritional testing.

Someday this will be cross referenced with genetics.

E.g. If you read about coffee, most report that it's a net positive. Drink more coffee. But if you're a slow metabolizer like myself, the caffeine stays in your system 4X the normal person and actually significantly increases your chance for a cardiac event.

So if you just read the pop-sci articles, kept drinking coffee, but you're the 1/3 of the population that's a slow metabolizer, you've been doing yourself a disservice your entire life. Worse sleep. More anxiety.

> BMI denialism

You've already pointed out that it depends on what you're using it for, and that's it's not especially useful on an individual basis. Why the weird Holocaust association?

BMI isn't a great measure for a lot of reasons.

There's way too much variation in height and muscle mass. There's variation based on race as well, for example CMS has different standards for DPP eligibility if you're asian [1].

BMI was created in 1830, and has always been of limited usefulness. There are much better methods for measuring health in relation to total body fat.

It is completely reasonable to be critical of it [2] when it's used improperly (which is very common).

I understand what you're saying, but I think a person that wins Mr. Olympia seven times is clearly a severe, severe, severe outlier. For a decade he was THE most well-built body on the planet. Literally ONE in 5 billion.

Obviously no measurement is "perfect" for "everyone", but BMI is a very good indicator for an extremely high percentage of the population.

For the average person that isn't doing something radical with their body for a specific goal (powerlifer, bodybuilder, olympian, etc.) BMI is a fantastic first pass indicator of how things are going general health/weight wise.

The model disregards ridiculous outliers like world class bodybuilders in order to be simple and useful for the other 99.999% of society.

According to BMI I spent years "obese" and am now "overweight" bordering on obese.

I'm about 16-18% body fat. I'm definitely muscular, but hardly in the .0001%. If I'm wearing a shirt, you can't really tell that I lift.

Hardly world class.

I can see from my Oura ring data that late night eating is hard on the body and the harm is correlated with the how heavy the meal was.

The issue is that it takes work to digest food. Your body does not get to rest as well when you eat late at night. You see it in your heart rate / hrv. Small amounts of carbs don't seem to matter much. A big protein meal is the worst.

yeah... but the likelihood that you have a high BMI because you're just so jacked is low. It's not perfect, but it's a good metric.

Although this has little bearing on the study, BMI works best for people of average height. Tall thin people have a high BMI, and unthin short people have a low BMI.

Math reason: the square term for height is incorrect, people are three dimensional and a cube would be more appropriate (the formula is (lbweight/(inchheight^2 * 703))).

Check the BMI of tall and short people that you know in this chart:

Worrisome to be sure. I knew skipping breakfast (and often dinner too) had little effect on weight, after years of that habit. What did work? Riding my bike on a week-long river-to-river 500 mile bike ride in Iowa this summer! That was a blast, I got stronger and I also lost a few pounds. Not for everybody I know.

I gained weight every RAGBRAI I did. Pie, beer, pork chops, walking tacos. Seems like I was eating or drinking beer every waking minute I wasn't on the bike. Worth it, though.

I rationalize, it's all muscle!
