Let’s be honest: You aren’t likely to
click on a snooze-inducing headline like “Eat More Vegetables and Protein, Less
Fat and Sugar to Lose Weight.”
Which
is why health and wellness sites are always on the lookout for the next hot,
new trend, like drinking black, mucky lemonade filled with charcoal or gulping
down tablespoons of coconut oil. But the desire for that shock factor may end
up misleading readers with sensationalized headlines and oversimplified
conclusions.
“The
media tends to blow up a research study and create headlines that target
people’s fears,” says Krista Haynes, R.D., and nutrition manager at Beachbody.
Another
problem with weight-loss trend stories is that there are too many bold,
generalized recommendations based on little solid scientific evidence, says
Lisa Hayim of thewellnecessities.com, M.S.,
R.D., nutritionist based in Great Neck, N.Y.
“One
day, low fat is best for weight loss, the next, we wake up to learn that high
fat is best,” she says. “These trends don’t take into consideration that every
person is different, and their ability to metabolize and use nutrients is very
different depending on their gender, age, body composition and exercise
regimen.”
So
before you try that “magic” diet/food/ingredient/drink/etc. to lose weight, you
should take the time to examine it with a critical eye.
But What About the Studies?
Many reputable publications will
include links to the actual studies in their articles to provide
substantiation, but readers who are scanning to get to the “good stuff”
probably don’t click through to read them.
But if you’re intrigued enough to
take a new eating trend for a test drive, you should check out
those links: “Go to the source (preferably the peer-reviewed journal that it
was published in),” Haynes says.
Reading dense medical studies
probably doesn’t sound like fun, but the good news is that it isn’t actually
difficult to figure out if a study is worth taking seriously — if you know what
to look for.
Here are some easy ways to fire up
your B.S. detector when it comes to examining the truth behind the latest
weight-loss trends.

Take headlines with a grain of salt
Headlines have to highlight the
article’s “hook”; there’s no space to include the fine print, such as
“Preliminary Research Suggests…”).
No one food or exercise routine is
likely to single-handedly overhaul your health, for example, so a headline like
“Eating Kale Slashes Heart Disease Risk by Half” should be regarded with a
healthy dose of skepticism.
Consider the subjects
Find out who or what the study was
done on before adopting a new diet trend. Were the subjects human beings,
rodents, or cells in a petri dish? Most scientists consider it irresponsible to
base recommendations for humans on the results of rodent studies, which is why
some publications won’t report on animal studies at all.
But others will, so you might want to
wait until similar results are found in humans before making any big changes to
your eating habits, especially when the safety of a trend is largely unknown.
Even if a study was done on humans,
consider whether its results might apply to you. So you may want to
ask yourself whether a study of 17 20-year-old males has any bearing on your
life or health. Or whether a study trumpeting “Walking Three Times a Week Cuts
Your Risk of Death by 30 Percent” might be applicable to your life when the
subjects were 70-year-old women with diabetes.
The size of the sample is also
important. It’s much less meaningful if a study reports that a risk for disease
“doubled” when researchers only studied 12 people.
Consider the funding source
Who funded the research? The
government doesn’t conduct its own studies to evaluate health product claims,
so they’re dependent upon companies’ own research.
The reality is that most research is
funded by companies that have a financial stake in the results. That doesn’t
mean that those studies always are unreliable, but it does mean you should
consider waiting until more evidence emerges to support a health trend.
Most studies will include a section
that discloses where funding for the research came from and a section in which
the authors disclose any affiliations with parties that might have a vested
interest in the results.
Another thing to look for: Sometimes
it’ll appear as though a health story is based on research when instead, the
news is about a summary paper a scientist presented at a conference. Although
the idea might be solid, be more skeptical of those types of research stories,
because they haven’t been reviewed by scientists’ peers or editors of quality
scientific journals yet.
Remember the “safety in numbers” rule
Don’t put your faith in a trend for
which there’s just one published study about it, Haynes says: “One study
doesn’t mean there’s a cause-and-effect relationship. Reproducing the same
results over and over is the best way to judge the outcomes of the studies,”
she says.
