Only read the past couple of posts but isn't blood work coupled with body fat measurement (calipers, dexa, waterstatic) the best way to test one's general health . You can look at the biomarkers and deduce what needs to be done accordingly. BMI is a good cheap indicator in high school since people don't exercise as much and don't have as much muscle maturity or use anabolics. However, I think around 20% of Americans are gymgoers, so it might not be accurate for the general populace.

BMI doesnt "accurately describe their body", its a very general measure of overall health using the relationship between height and weight. it doesnt account for muscle mass, nor fat mass, its more general than that.

BMI is a useful health indicator for 99% of the population. That there are edge cases does not discredit it's general use.

I know this topic is completely derailed but by today's standards most democrats would probably say 2008 0bama leaned right....

Which is sad.

You have yet to show any data whatsoever that your claim is in any way supported by ANY data. Why?

The answer is simple: BMI has only proven somewhat "accurate" in predicting the likelihood of health issues in the "Obese" and "Underweight" categories. The "Overweight" category, specifically, is not at all trustworthy without assessing the lifestyle of the individual. Even the CDC doesn't make any claims about "99% accuracy" even in the Obese category.

I bet everyone talking about BMI on here is fat as hell lol.

Correct. Note, the relevant (and stupid) claims that led to this conversation are here: https://forums.d2jsp.org/topic.php?t=84751616&f=119&p=568222059 and this response: https://forums.d2jsp.org/topic.php?t=84751616&f=119&p=568222257

There appears to be a lot of desperation to "win" a discussion that's mostly meaningless. BMI is a shit indicator of health outside class 2 and 3 obesity and underweight.

Also, for other measurement methods besides calipers: https://www.healthline.com/health/how-to-measure-body-fat#takeaway

The real irony is, it's entirely possible to be obese while being considered "healthy" based on BMI. Those are true outliers though, which'd be picked up by the 99% number Thor referred to.



Why are you arguing if you agree? Thor's claim:



Is false. The "overweight" category of BMI is more useless than not. The "Normal" category of BMI is also not an accurate indicator for 99% of the population either. Though it is pretty rare to find an obese person within that category. And the class 1 obesity metric is not anywhere close to even 90% accurate as a health indicator.

BMI is most useful as a health indicator at the "underweight" and class 3 AKA "Morbidly Obese" stages. But even there, the most generous health experts only rate the BMI index as a useful indicator of health 90-95% of the time. Thor made a completely wild claim that lacks any support in data or fact. Why are you defending him? He claims to be a healthcare researcher, a person who is supposed to be knowledgeable in the field. Shouldn't you be holding him to a higher standard?

there's no contradiction between "useful health indicator" and "general measure of overall health", even if they aren't synonyms.

knowing you're not "obese" or "underweight" is still a useful health indicator. you've played yourself sir, you're identifying 2 small by % groups and claiming that BMI is only useful to them. you haven't taken a second to think about the fact that not being in one of those groups is also a useful thing to know.

EDIT: this is like claiming cancer screenings are only useful to those with cancer. an idiotic line of thought really.

My BMI is 31. I definitely need to lose weight.

Just remember calories in/calories out and you'll get to your target goal in no time. Adopt a diet that you enjoy and will stiick with. Ensure you track your calories and weight progress on Excel or Google docs so you can calibrate your daily calories accordingly. Protein and fiber are very satiating. You don't need keto, fasting, etc especially if they make you feel miserable.

My BMI is 24.4 (high end normal). My estimated body fat percentage according to my doctor is 8.5%.

I do not go to gyms, ever. I just work. The highest my BMI has ever gone was 27.3 (low end overweight). At the time, I was in a heavy labor job. I passed out at work a couple times, they required me to go to the doctor to figure out what's wrong. Doctor didn't give me a real number, just said my body fat percentage was too low, and short term I needed to eat snacks at work, that my blood sugar was getting too low which caused the "faint". Long term, the doctor advised introducing a higher starch content into my diet, which was pretty low on pasta/starch, higher on vegetables, fruits, and lean meats. I do not eat any form of "dessert" beyond simple fruit, I do not drink sodas or any other sugar-based flavored drink. Water, orange juice, coffee, and vodka is about it (edit: Oh, every couple weeks I'll grab a 12 pack of ale). I followed the advice on more pasta, rice, and potatoes, saw no weight change, but was more solid through the work day.

Mostly meaningless post. You don't need a BMI indicator to know how healthy you are.

These days, outside of high school, BMI is really only used in national weight statistics to show that nearly all first world nations are full of overweight people, and third world shitholes are full of underweight people.

Another useless analogy btw. Cancer screenings are to determine if you have it or not so you can treat it. BMI is a scale primarily used to create statistical models designed to shame people. :)
