Weight loss success stories shouldn't be accepted without skepticism. I’m not referring to the outrageous claims like 'I lost 54 pounds with this magical solution!' Those are clearly nonsense. Instead, I’m talking about the stories that say, 'I struggled for years, but perseverance and effort finally paid off!' While the idea of hard work is appealing, it’s important to remember the concept of survivorship bias.
Survivorship bias is the tendency to focus only on those who succeed while ignoring those who fail. It might seem logical to emulate the winners to achieve similar results, but the problem is that the countless failures remain invisible. This creates unrealistic expectations, skews the perception of what success requires, and makes success appear far more attainable than it actually is.
This post was inspired by a recent article by Sol Orwell, co-founder of the independent nutrition research site Examine.com. While his article discusses the success and promises of figures like Tony Robbins, survivorship bias is equally relevant in the fitness industry. After all, we’re constantly bombarded with so-called 'successful' weight loss stories.
Many weight loss success stories are crafted to target what marketers refer to as your 'pain points,' drawing you in and making you wonder, What’s their secret? They reveal it, of course: They followed a specific diet, stuck to a workout plan, and waited for the perfect moment. Eventually, you think, Aha, that’s exactly what I need! And that’s when the gurus cash in—cha-ching! (It’s worth mentioning, however, that there are also many genuine and helpful experts out there.)
It’s no secret that what works for one person might not work for you, but I’ll say it again. These stories are undeniably motivational, filled with clichés, and can feel especially enticing if you’re facing similar struggles and the successful individual appears just like you (a common tactic). However, it’s crucial to remember that there are countless hidden details beneath the surface.
Perhaps they exercised three to five hours daily, or their genetics played a significant role in their results. It’s also possible they weren’t certain their efforts would pay off, and only later realized that their initial doubts were misplaced. As the You Are Not So Smart blog puts it more broadly:
Remember, those who fail rarely get paid to share advice on avoiding failure, which is unfortunate because, despite appearances, success often comes down to consistently avoiding major failures while enduring minor setbacks.
The next time someone shares their weight loss success story, make sure to ask these two critical questions:
How long have you maintained your weight loss? As we’ve previously noted, exercise is just a small part of the weight loss equation. In reality, many people regain the weight they lost—and sometimes even more. Before trusting someone’s advice or story, dig deeper into their long-term results.
Are you still following the same plan? After all, as you know, unsustainable diets rarely last more than a few months, if that.
The author of You Are Not So Smart further explains:
When seeking guidance, prioritize learning what to avoid, as Phil Plait recommended, but don’t expect this wisdom to come from the quotes or life stories of those who managed to stand out from the crowd.
Focusing solely on success stories provides a skewed and incomplete perspective of reality.
