Not Exercising Worse For Your Health Than Smoking, Diabetes and Heart Disease, Study Reveals (cnn.com) 213

An anonymous reader quotes a report from CNN: We've all heard exercise helps you live longer. But a new study [published in the journal JAMA Network Open] goes one step further, finding that a sedentary lifestyle is worse for your health than smoking, diabetes and heart disease. Researchers retrospectively studied 122,007 patients who underwent exercise treadmill testing at Cleveland Clinic between January 1, 1991 and December 31, 2014 to measure all-cause mortality relating to the benefits of exercise and fitness. Those with the lowest exercise rate accounted for 12% of the participants. Dr. Wael Jaber, a cardiologist at the Cleveland Clinic and senior author of the study, said the other big revelation from the research is that fitness leads to longer life, with no limit to the benefit of aerobic exercise. Researchers have always been concerned that "ultra" exercisers might be at a higher risk of death, but the study found that not to be the case. "There is no level of exercise or fitness that exposes you to risk," he said. "We can see from the study that the ultra-fit still have lower mortality."

          Not that it's not great that you exercise but the real answer to you feeling better is what you did here. Weight loss (which mostly comes from calorie restriction and not exercise, however exercise is great for many other things) is THE major indicator for improving health vitals in all studies.

            Weight loss (which mostly comes from calorie restriction and not exercise, however exercise is great for many other things)

            I hear this a lot, and it's false. People look for easy solutions and excuses, and it's a heck of a lot easier to do a diet than change your lifestyle, and this is an excuse for doing just that. But it's not true.
            Calorific deficit is what causes weight loss.
            If you do it through diet, chances are you lose both fat and muscle, and the deficit cannot be all that large or you'll get other deficiency problems. And at any rate, you cannot eat less than zero.
            If you do it through exercise, you'll only lose fat, not muscle, and the deficit can be as high as you push it.

            The reason I can state with certainty that you can lose weight (and more importantly, fat) through exercise and not calorie restriction is that I did it. It was simple maths: I burned around 1500 kcal a day if doing nothing, and no safe diet would be under 1000 kcal a day (and even that's pushing it). So that would be a 500 kcal deficit per day. But if I started exercising, burning 3000 kcal a day, without changing my calorie intake, that would be a 1500 kcal deficit per day.
            The path was clear, and it worked beautifully.

            The main problem was all the times people asked what diet I was on, and how they wouldn't believe me when I told them "none", because of the old wives' tale that weight loss starts in the kitchen and is 80% diet. It's a bloody lie that people use as an excuse for not getting off the couch.

            Now I am lean and no longer lose weight, but I continue exercising and simply eat more to keep my weight.

              Burning 3000 kcal per day is relatively difficult. It takes time and effort. Eating 3000 kcal is very easy. It is "rewarding", eating makes us feel good due to evolutionary reasons. It is not even expensive. Exercises provide significant benefits but to claim that they make diet unnecessary is obviously dumb.

              • It's dangerous if done for any extended period of time. The body needs a certain amount of power to run and without that it will start to break down or damage itself. The brain takes huge amounts of power on its own and I wouldn't recommend starving it. Sure fat stores are used to make up some of the difference but it is much harder for the body to burn fat for energy than food. You'll probably just feel like shit and be too lazy and exercise and too groggy to think straight.

            cardio doesn't directly help you lose weight by burning calories. Mathematically the 600 calories you burn in a workout doesn't add up to the weight you lose each week. However, it does increase your metabolism so that your basic metabolic rate increases, thereby burning more calories when your not working out also. Similarly by increasing your muscle mass also helps increase your BMR.

        I've heard the opposite and that it actually takes pathetically little effort to get a large amount of benefit, as in 15 minutes of brisk walking each day and it's going to have an impact. This has even been previously covered on Slashdot [slashdot.org].

        If you want to look like Mr. Universe or something like that, obviously you'll need to do a substantial daily workout, but basic health benefits don't require all that much. Just because you don't look like a gym rat doesn't mean that you're completely unhealthy.

(A good rule of thumb is to look at the nutrition labels. If the mg of sodium is less than the number of calories in a serving, you'll be below 2000 mg a day.)

    Spoken like a true statistician. However, the statement is provably false. Rhabdomyolysis in the Crossfit community is a thing. There are levels of exercise that expose you to risk, however extreme they might be. The fact that putting yourself into a "group" that is statistically healthier does not mean you are risk-free. That statement just strikes me as completely moronic, though I didn't RTFA so maybe he qualified it at some point, I don't know.

    This is not an argument against fitness. I absolutely believe in being fit and it's obvious that being fit improves and extends life, in general. But to make a blanket statement like ""There is no level of exercise or fitness that exposes you to risk" is just naïve or lazy.

  • And then you go check funding for the study, and the interest of the team and you'll see a big chain of fitness stores funded it.. no limit to fitness? BS as it also puts a strain on your system. And we've seen more than enough unhealthy living people outlive healthy living people..

      Did you really check the funding? I saw the study was done by the Cleveland Clinic which is pretty well respected but it wasn't apparent what the funding source was.

      The fitter your body, the better it is able to handle strain on your system. That level of fitness is improved by exercise (straining your system), but in degrees. Equally important to improving fitness are adequate rest and recovery along with proper nutrition.

      There is of course such a thing as over training which will decrease your fitness. The study didn't measure how much people exercised. It measured how fit they were. The fitter people were, the longer they lived and there did not seem to be a point at which improved fitness didn't improve their chances at a longer life.

      The study didn't say that there was no upper limit on how fit a person could be. My guess is that there's a certain level of fitness a person can achieve beyond which it becomes very difficult to become any fitter.
      • But the title and article suggests it depends on exercise, and not just fit..

          Well sure, if you're not fit now, you won't become more fit without exercising. But while exercising and fitness are inextricably linked, they aren't the same thing. Too much exercise can have negative impacts on your health AND your level of fitness. But what the study says is that improved fitness never detracts from your health.

    This study does not prove what it purports to prove. Namely, that people who are currently sedentary will live longer and be healthier if they change their habits to get more exercise.

    In order to show that, you would need to recruit sedentary people, then create an experimental group and a control group, and randomly assign participants to one group or the other. The control group would simply be monitored. The experimental group would receive an intervention that (ideally) caused them to exercise more. All participants would be tracked until death and then you could see whether the intervention was successful.

    The flaw in the current study is the assumption that sedentary habits are the CAUSE of high mortality. But it may simply be that some underlying trait (such as diet or a metabolic disorder) is responsible for both the sedentary habit AND the higher mortality. In other words, maybe healthy people are more likely to go exercise in the first place, because they have more energy and feel good.

      The study measured outcomes based on level of fitness. The study showed that the fitter you are the better your chances are of living longer.

      You're right in that it does not directly show that sedentary people would live longer if they start exercising but there are plenty of other studies that show that improved fitness comes with exercise. That's pretty well understood. It's about the only way to achieve better fitness unless you're already over-training.

      You're also right about the fact that there m

    a sedentary lifestyle is worse for your health than smoking, diabetes and heart disease.

    What I need is a list of options. How to balance the things I like with the things that will prolong my life to a reasonable extent (so I can continue enjoying myself).

    While it might be nice to live to a grand old age, for most people their ability to be happy in old age is limited by available cash, friends / relatives who still survive (I.e. a support network) and the physical and mental faculties to enable independent thought and movement.

    Another important point, not mentioned, is that of diminishing returns, At what point does the extra time required for exercise, including preparation, travel, showering, laundry, etc. take up more of a person's life than it is likely to extend it by? If someone spends an hour at the gym, 4 days a week (plus another hour for travelling, showering, etc) that is 400 hours a year. That is hours taken not from your *life* but from your quality time: after sleeping, chores, work, commuting, etc. That could easily be 25% of all your discretionary leisure time. So over 40 years of working, that amount of exercise would need to extend your life by an additional 10 years just to make up for the "lost" quality time you spent doing it.

    • At what point does the extra time required for exercise, including preparation, travel, showering, laundry, etc. take up more of a person's life than it is likely to extend it by?

      You're implying that the benefit of exercise is only to extend life. If your exercise is such a druge and you're only trying to get a few years extra then you're doing it wrong on the most fundamental level.

      You should find something that is fun, find something to relax your mind, if you're a social person find something to do with other people. Exercise right and your body releases loads of endorphins. You won't care about how much time you get at the end of the life, you'll be happier living in the now imp

      As the AC wrote, the key is to make exercise your "quality time". Biking, kayaking, hiking, running, surfing, falling trees, and construction are activities that require a high level of exertion. Exercise does not need to be done locked in a gym.

    Some years ago, not long after I got married, my mother in law observed that I wasn't particularly athletic unlike my wifes' cousin who was a sprinter, hoped for olympic medals etc.

    I said that while I would not win prizes for speed, I looked forward to a healthier life. She was very surprised that I really meant it.

    Over the following years, I did not have back problems, glandular fever and all the other things my wifes cousin did get. She may have been able to run 200m in far less time than I would take t

  • Personally I'd rather not exercise than smoke and have diabetes and heart disease whatever the doctors say.
  • According to another study, getting up and walking for 10-15 minutes every 1.5-2.0 hours is healthier than a single concentrated 2-6 hours of aerobic exercise. It's not a matter of exercising, it's a matter of regularly moving.
    • Though I don't walk 15 minutes every 2 hours, I do usually get in 1-3 15-30 minute walks around the parking lot every workday. I think that helps.

  • I believe that exercise is very good BUT I want to point out that my (quick) skim of the study indicates that this is not a controlled study, in the sense of "participant A was told to exercise and participant B was told not to". So unless I missed the part where they did that, this is a correlation... and it's entirely easy to construct a theory where people who are going to die find it harder to get motivated to exercise... effectively reversing the cause/effect relationship that would otherwise be reall

Every nonzero finite dimensional inner product space has an orthonormal basis. It makes sense, when you don't think about it.
