It's difficult to sum up an adequate response in a post reply, but given the author's sweeping general comments, I'll reply in kind.
This article seems to present inferred facts about a pre-assumed problem. Part of the difficulty may be a lack of definitions. What is exercise? How is it different from activity?
Very generally, the article suggests a moderation but to what level? The lowest common denominator or just the socially generated mean? With 68.8 percent of Americans being overweight, I'm not sure either of these measures are satisfactory.
Next we’re presented with the evidence of excess. Regarding illness as being an indicator of "Compulsive Exercise" the author may do well to look into heat-shock proteins (induced through high intensity exercise) and their health benefit. And the loss of interest in something once thought important always strikes me as odd. I at one time would beg, steal and cheat for my set of legos, I don’t know I would do that now. I also at one time thought 80s glam metal was the end all be all of music. My tastes have since changed.
The additional presumed depressed mood problem with being told that one cannot workout for a period of time seems to ignore studies which have suggested the impact of exercise on creating and maintaining a positive mood. Perhaps the inverse is also at play and not a bad thing.
Also presented is an idea that food and exercise should not be related? A quick reference to the Basal Metabolic Rate calculation would be well placed here.
And my score on the Compulsive Exercise Test was 74. But the test was based on a sample of under 400 young females so I’m not sure how applicable it is to a middle aged male.
