Now that I’m typing this, I still have no clue why I made this... but here it is. Enjoy!
Pexels is an excellent source of free, creative commons images and they have all the animals you need. Here's some geckos https://www.pexels.com/search/gecko/ :)
It can, but the ‘baby peacock’ thing has damped my enthusiasm.

That seems suspicious.
I consider myself on the skinny side so it was a surprise to be sure.
I am not an animal expert but just based on intuition this seems off...
Doctor: Your BMI is high I'd like you make some dietary adjustments.
Patient: BMI doesn't measure fat accurately for example professional Rugby players are marked as obese but aren't.
Doctor: Are you a Rugby player?
Patrient: No.
It's a good guideline. Don't let edge cases control your perception and let professionals do their thing with the tools they have -- they're aware of limitations that's why their professionals.
If we're just relying on the professional's opinion then they don't really need the BMI, right. They can just look at you and go "huh, you're looking a little thicc today."
BMI is a good tool for population health, a bad tool for individual health, and if it just so happens to correlate to your thiccness then you probably already know that.
I agree with parent that body composition analysis via DEXA or air displacement plethysmography is a far better metric.
I have no doubt that a carpenter can bang a nail in with a screwdriver 90% of the time, that's why they're professionals after all, but when I see it, I can't help but think "there's gotta be a better way mate."

Melanin doesn't effect fat comp... does it?

Because social matter
Different genetics lead to different health outcomes for the same body fat percentages - or the same BMI on a population level. Just as it's not a "social matter" that the prevalence of sickle cell is much higher in African Americans. It doesn't make sense to use health outcomes standardized against a BMI range for one population racial mix against individuals of a race not represented -- in at least two separate ways.
Hong Kong for instance sets the obesity cutoff at a BMI of 25. China and Singapore use 27.5 I believe. The WHO and various other organizations generally endorse lower cut-offs for people of Asian descent. [1]
That's not to say there aren't social aspects to obesity as well (obviously) but that's not what we're talking about right now, and parent dragging that in is just a distraction.
From [1] in the comment you replied:
> Access to medications and surgery should be improved, in part by updating US indications for therapies to reflect race‐specific obesity thresholds and through inclusion of Asian American people of all subtypes with lower BMI values in clinical trials.
I'm 5'11, 180 lb male, that counts as overweight.
I'm 18% bodyfat. You wouldn't even note me as being particularly athletic looking if you walked by, I'm right in the middle of the bell curve for "guy who works out sometimes". There's no way it should be flagging someone like me as overweight.
I went to a new primary care doctor and who said I was a bit overweight. I had the same initial response of "oh come on!" and general exasperation with the state of medical care.
The thing is, he really wasn't wrong. From an epidemiology perspective it is simply better to be leaner if possible. The fact that I didn't "look fat" isn't really relevant; I was still carrying excess adipose tissue.
I already had a DEXA scan booked and was planning to do a cut before that exam. I lost about 10 pounds over the next 8 weeks through basic caloric deficit and moderate exercise. It wasn't exactly fun but it also wasn't that difficult, and the results were far more impactful than I expected.
Yes, I looked noticably lean with more muscle definition. I also went down a pants size and felt better in general. My blood work, especially lipid panel, was better than ever.
All this is to say that, while BMI charts certainly have flaws, and all individuals are different, most of us can still improve our health and longevity prospects by shedding excess fat. And that probably is leaner than we might expect.
100% accurate. Caveat Emptor - the world does not understand even the smallest nuance that needs to take into consideration - in this case "guideline".
For example, the US DoD used BMI (DoDI 1308.03) to disqualify a friend of mine from joining. his actual body fat by DEXA? 7%, he was just short and very fit.
it's a useless statistic.
It says mine is 1.6%, which I'd say is at least 5% out.
Fat calipers would be less accurate than DEXA but much more accurate than Navy circumference method, yet a lot cheaper than DEXA.
It's a shame when people use those electronic home scales and believe the results. Someone was so happy to tell me they were at 10% body fat, I could only smile and nod...
Most healthy people would have difficulty dropping below 10-12% without very deliberate effort. And beyond that would probably be kinda freaked out when they start to see all the veins and striations appearing.
Most people at 30+ lbs further away from 'having abs' than they think. I see it time and time again.
Two interesting things that also came from getting the scan done was that it showed that I have poor bone density so that's an issue that needed addressing (and hopefully the second scan will show improvement) and the scan was part of a package where they also did a 3d scan of my body exterior, which I was able to download and 3d print. I plan on making a half-and-half model of my body's change upon hitting my goal body fat percentage.
The data is also dubious. I'm not going to enter every possible number to see what comes back, but the number reported here for cows is definitely wrong. Insects have cells that can store nutrients, but not adipose tissue in the familiar mammal sense that we have. There is no way to know how much fat they're actually storing at any given moment versus other nutrients.
I have a few thoughts:
- my intuitive sense of animals that are thin or fat is totally off. I think of cows as being fat (ex: "fat cow") but their body fat percentage is only 6%! I think of Gorillas being super fit and muscular but they're at 31%!
- I hate that I can't hit enter after changing the body fat percentage value and have it change
- on that note I'd prefer if there wasn't a "find my match" button at all—after changing the body fat percentage value the match should immediately update
- better than that would be a sliding scale of every animal and the one that matches gets highlighted and centered
- real-world pictures would be better and even better than that would be an image of the animal and a cross section/MRI of the animal where you can see the fat distribution
OP's source is a YouTube video that doesn't list their source. Given that video is post ChatGPT...
It could also be fun if one could fill out the age, weight, height and gender to calculate the bmi.
Now that I think about it it would be hilarious to use sliders and have a cartoon person populated with the data generated in real time.
The average body fat of a Kiwi woman is 25-31% according to ChatGPT.
The closest match is the sheep.
