The uselessness of data
February 20, 2017 § 14 Comments
You own a Fitbit, admit it. And after the first month, the only thing it measures is the fitness of the socks in the bottom of the drawer, where it permanently lives now. Right?
But wait. Fitbit and other fitness trackers, also known as sock drawer weights, are supposed to provide “real-time feedback that may be particularly useful to enhance lifestyle changes that promote weight loss in sedentary overweight or obese adults.” In other words … data!
Unfortunately, after billions were spent on the false promise of changing the way America eats through Apple Watches, Fitbits and etcetera, some skeptic, probably related to Billy Stone, decided to do an actual study using science and numbers and shit to see if the sock drawer weights actually work.
One such study started off by “recruiting 197 sedentary overweight or obese adults from the greater Columbia, South Carolina area.” I bet that was pretty easy to do. What would have been a challenge is “recruiting four non-obese adults from the American South.” But I progress.
So they took these poor folks, literally, and put them into four groups.
- Standard Care Group. Participants received a self-directed weight loss manual based on two evidence-based programs, Active Living Every Day and Healthy Eating Every Day. The manual’s focus was to help individuals adopt a healthful eating pattern and increase their physical activity levels through the use of cognitive and behavioral strategies consistent with the Transtheoretical Model and Social Cognitive Theory. Now I don’t know what that manual or model or theory are, but they sound a lot like Coach Castoria’s 7th Grade gym class at Jane Long Junior High back in August of 1979, where a rabid and sadistic football coach would spread a class of weaklings out on a 110-degree asphalt slab and scream at us to do leg lifts until we puked, which was about twice.
- Intervention Group: Same manual as above, along with a diary for participants to record daily meal and lifestyle activity, emotion, or mood. The mood section was pre-filled in with “hungry and pissed off about it.”
- Peer Weight Loss Group: 14 sessions with a facilitator using the manuals, with a weekly weigh-in and greater emphasis on weight loss than in the original programs. One-on-one telephone counseling sessions to provide continued support and enhance weight loss maintenance.
- Fitness Tracker Wearers: You know who you are.
- Peer Weight Loss Group + Fitness Tracker: Lecturing/scolding along with a fitness tracker.
Now before we get to the results and how it affects your cycling pro masters career, a couple of key facts. First, a bunch of people quit, which tells you all you need to know about fitness and weight loss. To recap: PEOPLE MOSTLY QUIT. Get it? No matter what you buy or how many power meters you own or how studiously you learn the CdA, most people quit.
THIS PROBABLY MEANS YOU. So, save your money and go buy some socks or some super stylish underwear. I recommend products by Stance:
Moving on, what the study found is that when you do a study there are a lot of numbers. And making sense of those numbers isn’t possible because the only number that matters was previously discussed and indicates that you are going to give up, which your sock drawer weight proves you already have. More importantly, the study found — and this is truly amazing — that doing something is better than doing nothing.
And unhappily for the Fitbitters out there, it didn’t matter whether you read a manual, got counseled, or did both in tandem. As compared to doing nothing, doing something was better.
I know, I know, let’s call up the Nobel Prize committee now. However, there were a few sad qualifiers that seemed to throw the entire study into doubt, raising the awful specter that doing nothing may be just as good as doing something.
To wit: The study noted that if your participants are university students, they are pretty much worthless at doing anything: “Students were the most unreliable group in this study, and their adherence was especially poor for homework assignments and other assignments.” Parents, time to start asking for some tuition refunds from those deadbeat kids! Also, we learned that since so many people quit, weight loss is hard.
Finally, we learned that the study was conducted by one “Dr. Blair,” who receives book royalties from Human Kinetics and honoraria for service on the Scientific/Medical Advisory Boards for Alere, Technogym, Santech, and Jenny Craig. In other words, this study, which so conclusively shows that your sock drawer weight is no better than Coach Castoria, also conclusively shows that even that flimsy conclusion is dubious at best. Because, industry bias and university students.
But back to your data driven cycling career. Tell me again how all those numbers are going to make you faster? Because first we’ll need to get together a control group, and I’m not planning on going to Columbia any time soon.
