    Carrying heavy bodyweight, whether muscle or fat, has been shown to be detrimental to health.

    It puts a strain on your heart in either case.

    I'm going to go out on a limb and say if we look at 2 6ft, 275 pound guys one is 15% BF and the other is 35% BF the guy with 15% is actually moving, getting his heart rate up, etc and most likely healthier.

    Is his heart healthier than another guy that is 6ft, 200 pounds and 25% BF? Someplace the streams cross.

    I don't know what the comparison date was, but if we are going back significant years, I don't think Americans exercise more is true. We may go to the gym more or do things we call "working out" more, but we are likely far less active in our daily lives (on average) even so.

    Re CI vs CO, it doesn't make sense to say one side is more important or 80% or whatever. The problem is that if you don't do something (it doesn't have to be counting calories) to control calories in, and if you live in an environment like ours where eating is super easy and cheap, then increasing exercise may just result in eating more. Especially since many think exercise burns more calories than it does and will see that as an excuse to eat more indulgently.

    I've lost weight just by increasing exercise, but it happened when my eating was already under control, so I didn't start eating more without realizing it. And I was truly exercising quite a lot (tri training)--many of the studies showing exercise does not help do things like taking someone out of shape and having them walk on a treadmill for an hour, which is both boring (people feel like it was more work than it was, since they hated it, and think they deserve a reward, food) and doesn't burn many calories.

    It looks like the report is comparing numbers from Jan-Sept 2017 back to 1997. Given that time frame, it actually doesn't surprise me that physical activity would be up. I'd be curious specifically how many more people work out at home given the rise of free or inexpensive (at least compared to gym membership) online services.

    Source: https://www.cdc.gov/nchs/data/nhis/earlyrelease/EarlyRelease201803.pdf

    ETA: The charts for "leisure-time physical activity" start on page 43 and show a distinct jump for people meeting the aerobic activity recommendation starting in 2009 with a general upward trend since then. The response for meeting aerobic plus strength recommendations is on page 46 and shows a general upward trend since 1997, although overall numbers are lower.

    I assume this is largely or entirely based on self reports. Perhaps a chunk of the exercise-increase statistical result arises from people gradually starting, around 2009, to feel better about themselves if they delude themselves into believing they routinely exercise, or simply wanting to look more respectable by lying about it?

    According to Wikipedia...

    The average American consumes 3750 calories per day
    2nd highest in the world

    PER DAY!

    And check how much non-work time people spend on screens. Not a good combination.
