Researchers have been studying what works—and what doesn't—for real, permanent weight loss for years. Various weight-loss interventions (from specialized diets to in-person support groups to educational sessions to weight-loss apps) have been analyzed, scrutinized, and reviewed in hopes of finding "the" answer to the obesity epidemic.|
But these studies, while more scientific and controlled than weight-loss reality shows, have something common with the latter: They rarely reflect how real people lose weight in the real world. Many weight-loss studies enroll volunteers who not only know they're being studied (which can skew results) but are usually paid for their participation—and even receive free access to a variety of weight-loss tools that might otherwise be out of their reach. I don't know about you, but if I wanted to lose weight and enrolled myself in a study to do so, was paid for my time, and received free access to experts, support groups, tools and more—I'd probably be more successful. Tell me to figure it out on my own and find my own motivation to stick with it, and my results would be entirely different.
A recent study broke all of the old rules in weight-loss research. Researchers from the University of Texas Health Science Center at Houston Medical School, led by researcher Kevin Hwang, M.D., M.P.H., wanted to see how well people would lose weight when they didn't get paid to do so, when they didn't know they were part of a study, and when they used a free, universally available weight-loss program on their own. The program they chose to examine was SparkPeople.com, America’s largest diet and fitness website by unique visitors, according to comScore, an Internet technology company. Yep, it's even bigger than Weight Watchers Online—but it doesn't cost members a dime.
Hwang and his colleagues report that this could very well be the first analysis of a natural cohort of members of a free online weight-loss community, so their findings reflect the real world. Moreover, “Because this [SparkPeople] online program is free, scalable, and widely disseminated, the potential public health impact is significant," the researchers wrote in the Journal of Medical Internet Research, which published their findings in February 2013.
So what did they discover?
Put simply, the more that members used and interacted with the SparkPeople website, the more weight they lost. More specifically, reporting weight changes (whether increases or decreases) and interacting within the SparkPeople Community forums were both associated with significant weight loss compared to those who did not use these tools. Additional SparkPeople tools other than the weight tracker and forums also correlated with increased weight loss in the study, but not a statistically significant amount.
SparkPeople engineers provided the researchers with data of a random sample of members who joined the site within a three-month period in 2008 and included all available follow-up data for these members through May 10, 2010. Members did not know their data was being collected or that they were part of a study, and all personal identifiers and usernames were removed for privacy. The final study sample included 1,258 members (91% female, average BMI of 31.6) who had at least two self-reported "weigh in" entries and adequate data to allow complete analysis.
Members who entered their weight at least four times a month lost 11 more pounds per month than those who did not, regardless of the duration of their membership. (Hwang said that they considered the possibility that "members made weight entries only when they were losing (rather than gaining) weight," which could have skewed the results. However, 71 percent of subjects in the study posted at least one instance of weight gain.) Likewise, members who posted at least one message on a message board in the SparkPeople Community lost 3 pounds more than those who did not post at all.
If you're reading this, chances are that you're already a SparkPeople.com member. (And if you're not, join now—it's free.) We've long known that our program, with its evidence-based and medically accepted recommendations for nutrition, fitness and weight-loss, works. But like any program, it works when YOU put in the work. This study shows that being an active participant in your weight-loss journey pays off, and confirms what previous studies have shown: that tracking your weight over time is beneficial to your progress. It also proves what SparkPeople has known from our own statistics and surveys for a while now: that members who have and utilize a support system, including our online forums, will get better results than those who go it alone. So consider this your call to action to get active in our vibrant and positive Community, to track your progress (you can weigh in right here!), and get engaged in the process of weight loss.
