Exercise Paradox
![Post Post](./styles/mcd/imageset/icon_post_target.gif)
Since the "Exercise, Health & You: How Much Is Enough?" thread is locked and I wanted to comment on it, I started a new topic. I hope this OK with you. In the original post of this thread, you wrote the following (in red):
We can also look at the issue another way, which I have discussed many times before. Let us say we have two identical people.
- one maintains a BMI of 18.5 and does so through a very healthy diet. They exercise moderately about 30 minutes a day, 5x a week and burn a total of about 2000 calories per day. To maintain their BMI, they consume about 2000 calories per day.
- the other identical person also maintains a BMI of 18.5 and does so through a very healthy diet. However, they exercise vigorously about 1.5 - 2 hours a day (or more) and burn a total of about 3000-3500 calories per day. To maintain their BMI, they consume about 3000-3500 calories per day.
All the studies in animals and the recent ones in humans show the first one will do much better and live longer and healthier.
Remember, a little is good, a little more may be a little better, but not that much and lots more is not good.
The latest post on this thread, dated April 8, 2017 discusses an article called the Exercise Paradox. This article presents the following concept: viewtopic.php?f=1&t=55287#p560778
If the Constrained model of energy expenditure is accurate, then both identical people in your example would be burning approximately the same amount of calories per day regardless of their differing exercise regimes.
Now that this study has come out, does it change your thoughts on this scenario? It seems to be based on the Additive model.
