Lately I've become addicted to watching documentaries.
I've seen documentaries on Native-American life, deaf entertainers, struggling single moms, the women's rights movement, female artists, recycling, the horrors of Walmart, the Joffrey Ballet, the 1980s, and several other diverse subjects. There's probably no documentary on any subject that I wouldn't be willing to watch.
It's good that I don't have Netflix because I'm sure I'd be watching its documentaries around the clock instead of doing more productive things (you know, like sleeping, eating, exercising, going to work, going outside, having a life, etc.). In lieu of that, DISH Network, which offers my beloved PBS and the recently-discovered Documentary Channel, keeps my DVR constantly filled with all the informative, entertaining documentaries I could ever want.
Three of the most interesting recent documentaries that I caught were Michael Mosley's trilogy, "Eat, Fast and Live Longer," "Guts," and "The Truth About Exercise," courtesy of PBS.
The first followed Mosley, a British journalist with a medical background, as he adopted, based on medical and scientific research, an intermittent fasting diet (eating normally for five days and drastically reducing calorie intake on two non-consecutive days) in an attempt to lose weight and stave off diabetes (to which he is genetically predisposed). His new approach to eating was surprisingly (to him and perhaps also to viewers) successful, as evidenced by improved blood work levels and modest weight loss, though less than enjoyable.
"Guts," as you can expect from the title, was fascinating but gross, and difficult to watch at times for those, like me, who are squeamish. (Particularly awful was a gory operating-room scene depicting far too much of one man's gastric-bypass surgery...yuck.) In this film, Mosley again offered himself as a test subject (he is seemingly willing to try anything for the sake of research), this time by swallowing a tiny camera (really!) that allowed a museum full of gawking onlookers to watch on a video screen the internal effects of his body's digestion of a hearty meal.
The most insightful, and possibly life-changing, for me of the three was "The Truth About Exercise." As a former (recovering) couch potato/junk food junkie turned exercise/healthy eating enthusiast, I've read a lot of books, articles, and websites devoted to exercise and nutrition during the past year and a half, and thought I knew a fair amount of information on those subjects.

But I was surprised to learn, along with Mosley, that a person who has steady amounts of physical activity throughout the day but does no formal exercise can be healthier (overall) than someone who completes an hour-long workout at the gym after a sedentary eight hours at the office. That was tested in the film's segment that stood out the most to me as the researchers monitored the daily activity levels of Mosley, a business executive, and a busy pub waitress. The most active of the three turned out to be the non-exercising waitress (who was on her feet all day, constantly moving) who had a healthier activity level than the executive who went to the gym after a sedentary day at the office.
An hour-long burst of daily activity does not make up for eight hours of relative inactivity, I was unpleasantly dismayed to learn. Like Mosley and the business executive in the film, I spend the bulk of my workdays sitting in front of a computer, but I work out for at least an hour, six days a week. Of course, I have previously read that sitting for longer than an hour without getting up and moving your body puts you at risk for health problems even if you do get or exceed the recommended daily amount of exercise, but I hoped that what I did was enough to make me fit and healthy.
So...like Mosley, who made small changes like walking more frequently and taking the stairs instead of "the lift" (and trying high-intensity training for a few minutes a week, which is reportedly more effective than working out for hours every week) for improved health results, I need to increase my activity level throughout the day instead of resting on my daily workout laurels...or, in this case, my ass.
