This one was hard for us to grasp, so it deserves some explanation. If a Paleo pancake calls for nothing but Whole30-approved ingredients (eggs and bananas), the flapjack is still off-limits. The Whole30 wants you to change your habits and your emotional relationship with food. "Your brain doesn't know the difference between an almond flour brownie and your mom's recipe; it just knows you crave sugar. So if you keep eating those sweets during the 30 days, your habits aren't changing," Hartwig says. Don't shoot the messenger!
To get an idea of what that means, we turned to the experts, including Loren Cordain, PhD, a professor emeritus at Colorado State University in Fort Collins, Colorado, and the author of The Paleo Diet; Erin Holley, RD, of Ohio State University Wexner Medical Center in Columbus, Ohio; and Lona Sandon, PhD, RD, an assistant professor of clinical nutrition at the University of Texas Southwestern Medical Center in Dallas.
And if you've really fallen off the bandwagon, a 30-day reset might be what you need. "Sometimes we need to do a complete overhaul of something in order to change that habit," Daniella Cohn, RD, explains. "Following a temporary diet that eliminates all of the junk that we tend to eat daily can be a great way to remind ourselves to pay attention to what we are eating and make healthy and informed food choices."
The idea is that these are the foods that our bodies were designed to eat while many of the heavily processed modern foods that fill our diets today contribute to chronic disease and health problems. Proponents of the diet suggest that a well-planned Paleo diet could lead to improvements in many aspects of health, such as enhanced weight loss and reduced inflammation.
A metaresearch group at Tilburg University in the Netherlands investigates scientists’ research methods and operations, scrutinizing questionable practices such as selective reporting of statistical tests and data massaging. The group instead advocates for practices such as preregistering studies and making experimental data immediately available for open external review and verification. Its members are optimistic that “the perverse incentives of careerist academia, to hoard data and sacrifice rigor for headline-generating findings, will ultimately be fixed.”
