Re: Not exercising worse than smoking, diabetes and heart disease study finds
#2There's a gentleman who spends an hour or so every night walking around the neighborhood. He's usually watching something on his phone as he walks, and he always smokes a cigar at some point.
I've always wondered if he'd be better off not exercising and not smoking that cigar. I guess now I know.

#3The article's title is somewhat misleading. The study emphasises the level of fitness rather than the regularity of exercise. [0]
> Question: What is the association between cardiorespiratory fitness and long-term mortality?
> Findings: In this cohort study of 122 007 consecutive patients undergoing exercise treadmill testing, cardiorespiratory fitness was inversely associated with all-cause mortality without an observed upper limit of benefit. Extreme cardiorespiratory fitness (≥2 SDs above the mean for age and sex) was associated with the lowest risk-adjusted all-cause mortality compared with all other performance groups.
> Meaning: Cardiorespiratory fitness is a modifiable indicator of long-term mortality, and health care professionals should encourage patients to achieve and maintain high levels of fitness.

Well, cigars surely cannot be in the same category as something you inhale.

That's a little pedantic, even for HN, don't you think? "Oh, it's not the exercise that's important, it's the stuff that happens BECAUSE you exercise."

How do you propose that someone attain a high degree of fitness without regular exercise?
Would it be insufficient for a study to tell people to drink more water even though we know it's not the action of drinking water that helps us, but the cellular interaction with it once it's inside us? And even though people could connect saline bags directly to their nervous system?
So, I'm wondering what you're clarifying.

They're not really comparable.
What good is being fit when you die in your 50s from lung cancer?

I think it's more that regular exercise isn't sufficient to actually have a high degree of fitness. If you exercise regularly but still over eat with a terrible diet then you're likely not going to actually get fit.

#9My work provides a gym, and I go there for at least an hour every weekday. I'd rather do poorly at work then skip exercising to be honest. I see some of the older employees coming in trying to reverse the effects of a sedentary lifestyle and I do not envy that position. It's crazy how people will deprioritze their health. It should always be a person's #1 priority to live as long as possible.
Of course, diet is also a huge factor as well. I stick to an intermittent fasting routine unless I can devote more time in the gym to bulking. I think fasting and caloric deficiency have some promising research behind it, and I think intuitively it makes sense that our ancestors would be eating only intermittently and probably never enough to put on a lot of weight. My nutritionist cautioned me, however, that there's still no scientific consensus and it still has a fad smell to it. It also takes quite a bit of mental discipline.
Also, if you're struggling with getting fit, GET A PERSONAL TRAINER AND NUTRITIONIST. You could not do more with your money than get professional help in steering your body in a direction that works for you. At the end of the day, you have to do what's right for your physiology and these trained professionals no how to make that easy for you.

#10Put bluntly, exercising creates new mitochondria in your cells. Since disease is often due to low cell energy (making cells underperform or malfunction), it makes sense that adding mitochondria (=adding ability to convert cellular energy) is very beneficial.
Here is a quite technical paper on exercise and mitochondrial biogenesis: http://m.jbc.org/content/282/1/194.full
