And BMI says nothing of body fat percentage Can have higher BMI and lower bodyfat I'm not convinced BMI is a useful metric

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…

It’s because people take their BMI and become shocked about where they land. It takes like a small beer gut to land in to obese.

BMI isn’t generally used as a picture of overall health anyway. More often, it’s used as a measure for health issue probability. As Texas BMI raises, it can be used to calculate the increasing chances of a huge variety of health problems.

They interviewed 310 ppl, calculated their BMI, then found out around half skip breakfast. That half had BMI a little higher than the rest. No discussion of what they eat. What a waste of time for everyone involved.

On one hand, I like the publishing policy of NIH, because more dissemination of information is a good thing.

But on the other, so many people gloss over or are just blatantly unaware that NIH specifically doesn't endorse anything about anything published there, that they're just a clearing house. And then people either infer authority from the domain, or they use that to consciously or subconsciously push their belief.

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.

Most people you see at a gym will probably be classified as 'overweight'. The fact of the matter is muscle is counted against you in BMI, and it takes very little to cross into the 'overweight' threshold. I would have to cut down to around 12% or lower body fat to be considered 'healthy', and I'm far from jacked. 1. Being sub 12% body fat (the highest BMI that would be considered healthy) is arguably unhealthy in and…

Most people don’t go to a gym.

12% body fat isn't a BMI, what are you trying to say?

BMI is not supposed to bucket you into healthy or unhealthy. It is a ratio of your weight to height. You're right that there are a lot of people who are overweight but are perfectly healthy. I think your problem is that you're viewing BMI as some kind of blanket good or bad health number. It is what it is, and it's just one aspect of your physical health, which you probably shouldn't be trying to capture in a single number anyway.

Go get a physical exam from a doctor if you want something comprehensive. If you just want a general height/weight ratio, BMI is pretty good for most people.

Pretty much only true if you are a body builder or someone else with an unusual amount of muscle mass relative to your height. For the vast majority of people though BMI is fine.

Very tall and very short people can also have BMI's that don't make sense.

99.99% of people BMI works just fine. As it turns out, most people in the western world are fat.

The musclebound people literally do not care about BMI because its irrelevant to them. Almost everyone else, should probably start eating less.

> 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.

Most people are fat. BMI is accurate for 99+% of people.

Would be interesting to see another study with people who do both breakfast skipping and skipping late-night eating. When I was in my 30s I was a typical woefully sedentary "IT potato" with more than a few extra kilograms around the waist, but today in my early 40s I manage to stay slim and free from diabetes despite being just as sedentary, and I'm convinced that my intermittent fasting is contributing to it: These…

I was pretty sure this is the normal way of intermittent fasting. Otherwise most people i know would almost be doing intermittent fasting all the time. How did you eat before, if i may ask?

Same foods, same amounts, but the time span was more typical and covered about 14 hours starting with breakfast around 9 in the morning and ending with a small snack around 11 in the evening (though never close to bedtime).

What I do now is to simply compress the same consumption (including the small snack after dinner) so that it fits in a span of 7 hours on average. I'm flexible with it since some days and schedules call for other plans. My goal is not complicated: eat nothing for an unbroken stretch of roughly 16 hours per day.

It seems like there are a lot of breakfast skippers on HN that don’t like the correlation.

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.

it seems likely parent is talking about his* required body fat to be considered in the "healthy" BMI range (under 25 for males).
