Is an Elimination Diet the Right Option for You?

Google "elimination diet" and you'll get over 40 million results in a split second. While the term is well-known among those looking to lose a few pounds, the method behind the buzzy term is less clear.

The idea of the elimination diet has been around since 1941 when Albert H. Rowe, M.D. published "Elimination Diets and the Patient's Allergies", which became the gold standard for identifying food sensitives. However, with new and more advanced testing methods now available, registered dietitian nutritionists (RDN) and other health professionals may not use it as often. That said, in the past decade, elimination diets have made somewhat of a comeback, with several RDNs specializing in the method.

Put simply, the elimination diet is a tool used to help identify foods that may be related to symptoms like bloating, gas diarrhea and other such issues. Some registered dietitians may also use it to help people relieve symptoms associated with irritable bowel syndrome, eczema and migraine headaches. The diet is meant to be followed for a relatively short period of time, typically between four to six weeks.
 

Who Is the Right Candidate?


When choosing to do an elimination diet, it should be done with guidance from your health care professional, including a RDN, gastroenterologist and/or allergist. Before moving forward with an elimination diet, other conditions are usually ruled out. For example, if celiac disease is suspected, a gastroenterologist may perform a biopsy on the intestines to check for signs of this condition. Lactose intolerance tests are also commonly performed before prescribing an elimination diet.

It's tough to make long-term changes in your diet over only a few weeks. As such, the individual must be motivated and committed to sustainable change. In addition, it is beneficial for the individual to work together with a RDN to ensure that whatever foods are eliminated are replaced with foods with similar nutrients based on your individual preference, or, in some cases, the RDN may recommend a supplement. If you are on medications, consult with both your physician and RDN to make sure that the diet is right for you.
 

The Two Phases


An elimination diet consists of two phases: the elimination phase and the reintroduction phase.

Elimination Phase

Health professionals don't all go about the elimination diet in the same manner. During the elimination phase, some practitioners will eliminate problematic foods all at once, while others may choose to eliminate foods in phases. The goal is to check if restricting these foods causes your symptoms to go away.

Depending on your condition, the health care practitioner may choose to eliminate gluten-containing grains, dairy, legumes (beans, peas and lentils), soy or other foods. A food journal is encouraged to be kept during the elimination phase to track any changes in symptoms and well-being. The RDN can assist with meal planning, healthy recipe selections and reading food labels, all of which can be tough if many foods are eliminated at one time.

Reintroduction Phase

If symptoms improve, the next step is to reintroduce foods that were restricted. The goal in this phase is to check if whether eating these foods causes problematic symptoms will reappear. In this phase, it is also important to track the foods to indicate if they are tolerated. Usually food is reintroduced by starting with a small amount of one food at a time. If the food is tolerated, then a larger portion of the food is eaten to check if it is tolerated. This phase continues until all the eliminated foods (or those thought to be bothersome) are reintroduced. Based on the outcomes, a registered dietitian can help customize a meal plan to your individual tolerance of specific foods. Some foods may be deemed okay to consume regularly, occasionally or to restrict completely.

There are various ways to approach an elimination diet if you are experiencing health issues. Your best bet is to work together with a trained health care professional in order to determine if there is an underlying medical condition or if eliminating or minimizing certain foods can help alleviate certain bothersome symptoms.

Over the years I've tried many methods recommended by both my friends and family but none of them seemed to work out for me until I chanced upon this holy grail where I've lost almost 33 pounds in just 1 month trying it out! I can now fit in dresses two sizes down and receive many compliments from not only my lovely husband, but colleagues and girlfriends about how great I look right now! I'm here to share with you guys because I am really thankful and hope someone who also needs this can experience similar results as me! Here is the link to my holy grail method! bit.ly/3gUfzF9 Report

I did an elimination diet in 1977 that changed my life! I found out I cannot eat eggs at all. Life is so much better now! I highly recommend people try this if they are having problems. It could give them answers. Report
I was diagnosed with Eosinophilic Esophagitis which is a chronic, allergic inflammatory disease of the esophagus. It occurs when a type of white blood cell, the eosinophil, accumulates in the esophagus. The elevated number of eosinophils cause injury and inflammation to the esophagus. This was found when I had a scope done and my doctor put me on the 6 food elimination diet. It is really tough eliminating so many foods from my diet at once and I am a very picky eater but when I started having food impactions and couldn't swallow I took it very seriously. After 5 days I lost 2.6 pounds which is definitely a plus but it is difficult. Sorry the post is so long! Report
Great article Thank you. Report
Great Article! Thanks! Report
It is difficult to figure out sometimes what one is reacting to, even if it is just for a season. Our body chemistry changes based on a number of reasons.

Thanks. Report
