Difference is just 5.8 per 1000 person-years. The effect size is very modest. You spend more time in exercising than increase your lifespan. The metaphor is literal, you are running from death and disease, and death is running faster. What we need is review studies ranking lifestyle and health regimes by their effect size and combined effect sizes. Almost certainly combining two effective regimes increases the life-…

Your assertion here is that the lifespan of a healthy person and one of the unhealthy individual is the same. They are not.

The healthy person has less stress, sleeps better, has better sex, has better mood and energy and isn't spending most of his life having difficulty dealing with illnesses steaming from unhealthy habits.

Additionally, the time spend exercising isn't wasted, it's quiet enjoyable thanks to the release of Endorphins. Not to mention that it helps build muscles and keeps your body in shape which makes you more attractive to the opposite sex, thus increasing the chances of finding a partner. You also get all the cognitive benefits mentioned in the article for free.

To top if it off, the time commitment isn't 8 hours a day. It only requires an hour every 2 days or so (it varies depending on what you're trying to accomplish).

I highly recommend it.

HIIT fits the bill https://en.wikipedia.org/wiki/High-intensity_interval_traini...

In my experience, HIIT is unbelievably effective but there is a bit of a tradeoff with this path. If you can make yourself do proper HIIT regularly you will become batman but the mental barrier of intentionally making something "suck" as much as possible (and then some) is really tricky to get over. Even once you are "on the wagon" it's a difficult habit to maintain. I find 30-60 minutes of moderate daily cardio to b…

Crash after high intensity exercise is pretty common. One thing that helps is carbing up before your exercise. Problematic if you are trying to diet down I guess, so high carb before exercise and high protein after exercise is probably a good solution.

The cost of diet point is absolutely true. I'm a writer and filmmaker living in Europe - i.e.: poor. I've also got a variety of food intolerances and health issues, which compound over time. To help with stomach and sleep issues I'm currently trying to eat only foods I cook from scratch: mostly fish, meat and veg and a little fruit. It's wildly more expensive (and time consuming) than cooking prepackaged food. Fortun…

> pasta, chips, processed meat and other cheap carbs. Carbs are one aspect of diet. There's very little actual nutrition in any of those things.

Yes, that's my point... It's cheaper to eat poorly. It's (significantly) more expensive to eat well. As I said before I'm spending more than twice as much cooking from scratch. And (as I'm coeliac and intolerant of milk) I wasn't eating the cheapest food before by any means. I reckon here in Dublin, the cheapest (and extremely unhealthy) diet of oven chips, pasta, bread etc - could be had for well under 20 euro per person per week. Whereas my partner and I are currently spending around 150 on veg and meet between us.

Looking at car ownership rates in the US over time and comparing to hypertension rates over time there doesn't seem to be much correlation.

I'm surprised I need to say this on HN, but you can't make inferences from this sort of uncontrolled choose-your-own-correlation-adventure in a whole population over time because thousands of things have changed in the population over that time. If this were your epistemic standard, you'd have to accept all sorts of absurd or conflicting conclusions.

When someone is suggesting that a particular thing is causing or partly causing a particular outcome it is not a choose-your-own-correlate-adventure to look at how prevalence of that thing and that outcome have changed over time.

Things tend to be affected by their causes (!) so when the outcome is changing significantly and the purported cause is not then it suggests more evidence needs to be offered before we accept that the purported cause actually has a significant affect.

There is an undercurrent of skepticism and contrarianism bordering on anti-intellectualism on this forum - especially with those accounts started after the pandemic. This is just one of dozens of studies that have shown that good cardiovascular health (a side effect of "vigorous" exercise) has a downstream positive effect on health. And I personally can attest to that - the days I don't vigorously exercise (run, swim…

This should be quantifiable. Use an LLM to help identify this undercurrent you’re referring to in maybe 10,000 conversation threads using the API from the footer. A thread being a reply to a topic, and a singular chain of replies. Then use that to train an RNN for sentiment analysis based on the values you’ve just described. Then run the entire HN corpus through your RNN and chart the values over time. For bonus poin…

You don't need an LLM for sentiment analysis.

I also don't want to pay for scraping and data ingest costs out of my personal pocket.

Feel free to do it if you want - it would make a nice blogpost.

If you want slimmer people, invest in hunger-stopping pills. Have a lettuce satiate you like two ham and cheese baguettes, and the obesity problem will disappear overnight.

I find it interesting that you assume the issue is related to hunger.

Most overweight and obese persons I know are overweight because they are using food as a drug. This has nothing to do with hunger.

Shoveling fistfuls of Reese's Puffs into your face because you're bored, sad, stressed, angry, etc. is not to relieve hunger pains.

It's to get high.

40+ years ago these people would have been chain smokers instead.

Want to fix the obesity crisis? Design a cheap, socially-acceptable, ritualized drug which can be consumed using little-to-no energy in near-limitless quantities and has no preexisting history of being considered "bad".

I am also a fit person. When I hear someone tell me that they don't have time for doing exercise I do not respond, I just listen and watch. I almost always will see the same person in the next days watching TV, or social media or playing video games for hours. I do minimal high intensity exercise every single day, it is just routine, because I am busy. Everyone can learn that. In fact I see the biggest number of bett…

Sure, and you’re right in plenty of cases. But likewise if your day to day is hard, stressful and has a decent amount of worry then once you’ve got the kids to bed at 8:30 the will power required to do some exercise is monumental. Quite frankly their will power points are gone for the day. So, instead try to find a way to squeeze exercise in as part of daily life (essentially habit stacking)

I think the positive effects for physical exercise in cognition and hypertension are fairly well known. There are other factors like alcohol consumption and stress have high correlation on the downside as well. I have a family history of alzheimer's and have hypertension so have a personal interest in looking after my mental health. What I can recommend from personal experience is: 1) Regular exercise with a routine…

Jesus, you manage stress by doing chores?

I had a highly-educated, very intelligent girlfriend once. She loved cleaning the toilet. She said it relaxed her and she enjoyed seeing the results of her work immediately.

I am no expert on the public health system and so I'm more than willing to be educated/corrected here, but I have the following impression: There is more money to be made by stakeholders treating health problems than there is in preventing them. And so there is a lot more money and effort invested in developing pharmaceutical and treatment solutions than there is in preventing the problems they treat – even though th…

Well, one clear market-based solution would be pricing transportation appropriately. If people were allowed to not pay for car infrastructure (via parking minimums, restrictive zoning, taxpayer-funded highways, etc. et.) and take their bike and train instead there would be a strong price signal to encourage the healthier activity. I moved to the Netherlands a year ago and have already lost 9kg (about 20 pounds) witho…

About half of the people United States are on government supplied medical insurance, and most of the people in other countries are on some version of that.

It is cheaper for people to die younger and so we should be encouraging unhealthy habits if we want to minimize medical care costs.

In spite of it's near ubiquity, I am trying to avoid the phrase "health care" because that is, as another comment talked about, not really what we do.

The barrier to exercise isn’t money in most cases. It is that exercise is misery. Exercise sucks. I am overweight. I much prefer Ozempic (and pay a substantial premium for it) vs lifestyle change. So do millions of other Americans who are shelling out for it. You would basically need to economically torture fat people to the point that exercise is less horrible than your incentives. I’m paying 8K a year to avoid exer…

> Exercise sucks. Lots of people, including myself, love exercising. If nothing else, endorphins are a great natural "high". And I can tell that the rest of my system just works better when I'm working out regularly: I have fewer hunger attacks, I sleep better, I feel better. And, I just really like the feeling of picking up really heavy things (that being my current exercise of choice). From what I can tell, the "ex…

> Lots of people, including myself, love exercising.

great, good for you and those people. but clearly most people don't.

plus you cannot out-exercise a poor diet. doesn't matter how hard you go in the gym or on a hike if you slam donuts and pepsi all day.
