There is little point of doing a study based on BMI when what you want is body fat. BMI is imperfect. It’s fine when you want to give people a quick metric for them to assess their fitness by themselves. People who are extremely fit with a high BMI already know they are extremely fit after all. It’s not fine when you want to analyse the effect of different life styles.

It’s easier to gather hundreds of people’s BMI for a study than it is to measure fat, which can also be misleading depending on the method used.

It's even easier to not do the study if you are going to use bogus data anyway.

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.

> RAGBRAI

I had never heard of that before, but after looking it up I really wish I was close enough to participate. Sounds like a lot of fun.

> 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.

Outliers don't count in studies, for very good reasons. It is understood that when we say "all" we mean "close to 99%", and for 99% of the population with a BMI over 30, they are overweight.

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…

Congratulations on discovering that tail ends of distributions exist.

It doesn't invalidate anything in the comment you are responding to.

I would love to see a study where they compare the skip-breakfast/eat-late behavior to circadian rhythm and then normalize for that to see if people who work to their actual circadian rhythm are less likely to be diabetic than the 8-5 crowd. Because I know that left to my own devices, I wake at 10am, eat at noon, and go to sleep at 1am, but "real life" means I wake up 4 hours "off schedule" so my diet clock doesn't match my sleep schedule.

I'm firmly in the 'overweight' category based on BMI, at 15% bodyfat, and I wouldn't classify myself as jacked. I have a bit more lean muscle than most from cycling but definitely not a 'gym body'.

Yeah, I'm 'overweight'. I run a lot and generally in pretty good shape. But I could absolutely lose 10-20 lbs of fat. Just because you're a little overweight doesn't mean you're unhealthy.

If you could lose 10-20 lbs of fat (and don't just mean, you have 10-20 lbs of fat left), then tautologically it would be healthier if you did lose the weight. The degree to which it makes you healthier is debatable, but that extra weight isn't making you more healthy (outside of people that are very underweight).

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…

I think you have a misguided idea that most people at the gym are buff, muscular, etc...

This couldn't be further from the truth.

> Breakfast skipping and late dinner intake were associated with obesity, while only late dinner consumption was associated with poor glycemic control.

So they measured that if one doesn't eat breakfast they were more likely to be obese than people that did eat breakfast?
