Is a 21-Day Elimination Diet Right for you?


You’ve tried eating gluten free, even though you’re not sure if you’re allergic to gluten. You thought about cutting nightshades out of your diet after reading a post on social media.  Maybe you even went vegan for a while. And every time you cleaned up your diet, you felt a little better—but you’re not exactly sure what works for your body … and what definitely doesn’t.

Here’s the thing—many of us have quite a few “trigger” foods that just make us feel off. For some, it’s equivalent to a serious food allergy that causes everything from hives to anaphylactic shock. But it’s far more likely that your body’s adverse reactions to certain foods or ingredients are much more subtle. Symptoms like bloating, digestive discomfort, gas, skin problems, headaches, and even fatigue can all be signs that you have a slight food intolerance.

But without taking an expensive allergy test, it can be really challenging to determine which foods are triggering your uncomfortable reactions. And even if you do take an allergy test with your physician, sometimes there are discrepancies and inaccuracies. One of the easiest, cheapest ways to find out exactly what causes a deleterious response is by going through an Elimination diet. In fact, IIN recommends that all graduates try a 21-day Elimination diet in order to determine exactly which items in their diet makes them feel energized and healthy, and which foods or ingredients are holding them back from feeling their best.

It sounds a little intimidating, but it’s actually pretty easy to follow a 21-day elimination diet at home. There are a few different ways to go about it, but generally, you’ll start by cutting out three of the most allergenic food groups from your diet—dairy, grains and gluten. You’ll also need to ditch fast food—the preservatives and processed ingredients in fast food can cause an inflammatory response in your body—and alcohol for 21 days straight.

Why three weeks? It takes 21-23 days for the antibodies in your bloodstream to turn over. Antibodies are activated by intruders like bacteria and viruses, but they’re also triggered by allergic reactions. After 21 days, you should notice a serious decrease in the amount of inflammation (which is caused by an antibody response) that you see or feel. It’s really important to stay honest with yourself when you try an elimination diet—slipping up and noshing on a slice of cake or even snacking on a handful of nuts could mess with the outcome.

After you’ve completely eliminated those three allergenic food groups from your diet for 21-days, you’ll slowly start to reintegrate each group into your day-to-day. Start slowly, first adding dairy back into your meals. Two to three days later, you can try eating gluten, too. As you add foods back into your meals, you’ll notice almost instantly when something causes a negative reaction in your body. Seriously, the reaction can be fast and BRUTAL! We’re talking upset stomach, headaches, hives … and even, ahem, bathroom problems.

Obviously, if something instantly makes you feel ill, that’s a pretty good indication that you have an intolerance to that food. The good news is that food intolerances are things that can come and go—sometimes, all you need to do is lay off the diary/gluten/grains for a while to allow your body to recover, and then you can slowly begin to reintegrate that food into your life. Of course, if it’s more serious than an intolerance—like a dairy allergy or Celiac disease—you’ll probably need to avoid eating that food for good.

So, is trying an elimination diet right for you? If you think you have a food intolerance or allergy, it might be just the thing you need to finally understand what’s best for your body!
