If you’ve ever tried a diet after hearing a friend rave about the weight they’ve lost on it only to find yourself hungrier than ever with nary a kilo shed, you are not alone.
And now, thanks to science, there’s a very good reason why you might be striking out with your diet while your friend has found success.
A new study examined the diets of 1,100 adults in both the U.S. and the U.K., testing their blood sugar levels prior to and after meals. Despite the participants consuming the exact same meals for 14 days (three types of muffins), no two people produced the same results—even though 60% of the subjects were identical twins—indicating that diets are not a one-size-fits-all situation.
Tim Spector, an epidemiologist and the study’s lead author, expressed his thoughts on the findings in an interview with Business Insider.
“Even we were surprised by the results, ” he said.
“Just because some diet or recommendation is out there doesn’t mean that you fit it. We should be personalising diets and not just trying to squeeze everyone into the same shoe size.
“For most people, we can make basic recommendations about how they respond to carbs in general, or fatty foods.”
What all of this ultimately translates to is the importance of finding exactly which diet works for you. This can be worked out by noting how your body responds to particular foods, which does take some time as well as a bit of trial and error. Spector is currently in the process of creating an at-home blood sugar monitoring kit to help people do exactly this.
If you are struggling to find a diet that works for your goals, it may be worth consulting a nutritionist to help cater to your individual needs.
