For three weeks, certain food groups are eliminated, which could allow individuals to observe how their bodies react as they reintroduce them (<\/span><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/books\/NBK599543\/\"><span style=\"font-weight: 400;\">2<\/span><\/a><span style=\"font-weight: 400;\">).<\/span><\/p>\n<p><span style=\"font-weight: 400;\">But what does it really mean to follow an elimination diet?

In this article, we\u2019ll break down these topics and provide practical tips that could be useful for those who&#8217;ve been prescribed an elimination diet and want to better understand their relationship with food.<\/span><\/p>\n<h2 style=\"text-align: center;\"><span class=\"ez-toc-section\" id=\"What_Do_You_Eat_on_the_21-Day_Diet\"><\/span><b>What Do You Eat on the 21-Day Diet?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">As you start the 21-day<a href=\"https:\/\/betterme.world\/articles\/elimination-diet-recipes\/\"> elimination diet<\/a>, one of the questions you may be asking yourself is: What do you eat on the 21-day diet? It\u2019s important to remember that there are many types of elimination diets, each with its own guidelines and approaches. However, the main goal is to identify foods that could be causing adverse reactions in the body.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">During this process, certain foods that are common allergens or that may trigger sensitivities are eliminated for a set period of time, usually 2-4 weeks. Some of these can include:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Dairy:<\/span><span style=\"font-weight: 400;\"> Dairy products such as milk, cheese, and yogurt and their derivatives may be eliminated because many people could experience direct symptoms, particularly from milk, such as bloating, gas, or digestive discomfort after consumption (<\/span><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/30783042\/\"><span style=\"font-weight: 400;\">3<\/span><\/a><span style=\"font-weight: 400;\">).<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Gluten:<\/span><span style=\"font-weight: 400;\"> Foods that contain gluten, such as wheat, barley, and rye, are usually excluded to identify potential intolerances (<\/span><a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC10096482\/\"><span style=\"font-weight: 400;\">4<\/span><\/a><span style=\"font-weight: 400;\">).<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Added Sugars<\/span><span style=\"font-weight: 400;\">: Certain refined sugars and artificial sweeteners may be avoided as they could cause gastrointestinal issues (<\/span><a href=\"https:\/\/www.frontiersin.org\/journals\/immunology\/articles\/10.3389\/fimmu.2022.988481\/full\"><span style=\"font-weight: 400;\">5<\/span><\/a><span style=\"font-weight: 400;\">).<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Processed Foods:<\/span><span style=\"font-weight: 400;\"> Ultra-processed foods, which often contain additives and preservatives, may be eliminated as they could contribute to inflammation and disrupt gut health &#8211; this will allow the digestive system to rest and recover (<\/span><a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC10058108\/\"><span style=\"font-weight: 400;\">6<\/span><\/a><span style=\"font-weight: 400;\">). Some of their ingredients may also need to be avoided for specific reasons, depending on the reason for the elimination diet.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Nuts:<\/span><span style=\"font-weight: 400;\"> Nuts may be excluded due to their potential to cause allergic reactions in some individuals (<\/span><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/30860761\/\"><span style=\"font-weight: 400;\">7<\/span><\/a><span style=\"font-weight: 400;\">).<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Fish and selfish:<\/span><span style=\"font-weight: 400;\"> Certain types of seafood may also be avoided as they can be common allergens (<\/span><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/26252073\/\"><span style=\"font-weight: 400;\">8<\/span><\/a><span style=\"font-weight: 400;\">).<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Legumes<\/span><span style=\"font-weight: 400;\">: Some elimination diets may exclude legumes, particularly soy and its derivatives, in addition to other legumes in large quantities, as they could potentially ferment in the gut and lead to digestive symptoms in some individuals. While legumes are generally considered incredibly healthy due to their fiber content, their potential to cause discomfort in certain people may justify their temporary removal from the diet.\u00a0<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">It\u2019s important to note that the specific foods eliminated will depend on the type of elimination diet that is being followed and the objectives you aim to achieve. Certain diets may necessitate the removal of other foods, such as eggs, especially in the 6-food elimination diet that will be discussed later. In addition, specific fruits, vegetables, and other items may also be excluded, as seen in the <a href=\"https:\/\/betterme.world\/articles\/is-avocado-low-fodmap\/\">low-FODMAP diet<\/a>.\u00a0<\/span><\/p>\n<p><a href=\"https:\/\/quiz.betterme.world\/en\/first-page-generated-gender?flow=2196&amp;utm_source=Blog&amp;utm_medium=Blog&amp;utm_campaign=21-Day_Elimination_Diet\"><img decoding=\"async\" class=\"aligncenter size-large wp-image-71091\" src=\"https:\/\/cdn.betterme.world\/articles\/wp-content\/uploads\/2020\/08\/511-asian-weight-loss-1024x640.png\" alt=\"21-Day Elimination Diet\" width=\"770\" height=\"481\" srcset=\"https:\/\/stage.betterme.world\/articles\/wp-content\/uploads\/2020\/08\/511-asian-weight-loss-1024x640.png 1024w, https:\/\/stage.betterme.world\/articles\/wp-content\/uploads\/2020\/08\/511-asian-weight-loss-300x188.png 300w, https:\/\/stage.betterme.world\/articles\/wp-content\/uploads\/2020\/08\/511-asian-weight-loss-768x480.png 768w, https:\/\/stage.betterme.world\/articles\/wp-content\/uploads\/2020\/08\/511-asian-weight-loss-1720x1075.png 1720w, https:\/\/stage.betterme.world\/articles\/wp-content\/uploads\/2020\/08\/511-asian-weight-loss.png 1920w\" sizes=\"(max-width: 770px) 100vw, 770px\" \/><\/a><\/p>\n<p><span style=\"font-weight: 400;\">However, the most important aspect is to focus on what you can eat. The 21-day elimination diet emphasizes including fresh and nutritious foods that contribute to your well-being. Here are some options you might consider:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Fruits and Vegetables:<\/span><span style=\"font-weight: 400;\"> A wide variety of fresh fruits and vegetables is fundamental. These are not only rich in vitamins and minerals but also provide fiber, which could help with digestion and promote gut health.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Lean Proteins:<\/span><span style=\"font-weight: 400;\"> Sources of protein such as chicken or turkey are excellent options.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Gluten-Free Grains:<\/span><span style=\"font-weight: 400;\"> Grains such as rice, quinoa, millet, and buckwheat are suitable options as they are easier to digest and don\u2019t contain gluten.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Seeds:<\/span><span style=\"font-weight: 400;\"> Chia seeds and flaxseeds are great sources of healthy fats and proteins, which could be beneficial for your overall health.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Healthy Oils<\/span><span style=\"font-weight: 400;\">: Oils such as olive oil and avocado oil are ideal for cooking or dressing salads, providing healthy fats.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">In summary, the 21-day elimination diet isn\u2019t just about what you eliminate, it\u2019s also about what you include. By focusing on nutritious foods and balancing your meals, you may start to better understand your relationship with food and how certain foods could influence your health and well-being.<\/span><\/p>\n<h2 style=\"text-align: center;\"><span class=\"ez-toc-section\" id=\"What_Is_Stage_1_of_the_Elimination_Diet\"><\/span><b>What Is Stage 1 of the Elimination Diet?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Stage 1 of the elimination diet focuses on the removal of certain foods over a period of 21 days. As previously mentioned, this approach could help identify possible food intolerances or sensitivities. Eliminating these foods may allow the body to recover and symptoms to subside, laying the groundwork for the next phase: reintroduction.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Elimination is the first step in this process. By removing foods that may potentially cause adverse reactions, which you may have been consuming daily, you can observe how your body responds without them. This may help identify symptom triggers and promote greater awareness of the relationship between diet and overall well-being.<\/span><\/p>\n<p><strong>BetterMe: Health Coaching app is a foolproof way to go from zero to a weight loss hero in a safe and sustainable way!

The good news is that generally, the foods that are allowed in most elimination diets are of high nutritional value, so you shouldn\u2019t worry about not getting enough nutrients during these days or about going hungry, particularly if you can be flexible and a little creative. Allowed foods typically include lean meats such as chicken, turkey, and sometimes fish, in addition to various fruits and vegetables. Rice and other grains are also permitted, along with healthy oils such as olive oil.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">At the end of the 21 days of the elimination diet, you proceed to the second stage where foods are reintroduced in a controlled manner. This process is essential for identifying which foods may be causing problems. Reintroduction should be done one food at a time, as this will allow you to observe any adverse reactions. Once a formal diagnosis is made, strictly avoiding the offending food until symptom control is maintained becomes the primary focus (<\/span><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/books\/NBK599543\/\"><span style=\"font-weight: 400;\">2<\/span><\/a><span style=\"font-weight: 400;\">).<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Remember that it\u2019s necessary to perform this process under the supervision of a healthcare professional to ensure adequate nutrition is maintained and reactions are managed properly.\u00a0<\/span><\/p>\n<p><em><strong>Read more:<\/strong> <a href=\"https:\/\/betterme.world\/articles\/real-food-vs-processed-food\/\">Real Food Vs.

Generally, in most elimination diets, foods that are known to be common triggers of adverse reactions, such as dairy and wheat, are excluded. However, it\u2019s important to understand that each diet should be tailored to the individual needs of each person.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">One of the most common elimination diets is used to identify food allergies. In this context, it\u2019s recommended to eliminate those foods that are considered the most frequent allergens. In a 6-food elimination diet, the most commonly implicated allergens are:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Milk and dairy products.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Eggs<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Soy<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Wheat<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Nuts and peanuts<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Fish and shellfish<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">In addition to the 6-food elimination diet, there are approaches that involve the elimination of one, two, or four foods in a similar manner. For example, some people often opt for a <a href=\"https:\/\/betterme.world\/articles\/low-fodmap-meal-plan\/\">low-FODMAP diet<\/a> to manage irritable bowel syndrome, which involves the elimination of certain fermentable carbohydrates that could cause digestive discomfort. Another option is the gluten-free diet, which is commonly used for those who have been diagnosed with celiac disease (<\/span><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/books\/NBK599543\/\"><span style=\"font-weight: 400;\">2<\/span><\/a><span style=\"font-weight: 400;\">).<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Regardless of the elimination diet chosen, it\u2019s essential to have the assistance of a healthcare professional. The guidance of a registered dietitian can help ensure adequate nutrition is maintained and desired goals are achieved, and your doctor will also be monitoring your symptoms and response to the diet.<\/span><\/p>\n<h2 style=\"text-align: center;\"><span class=\"ez-toc-section\" id=\"What_Is_the_Perfect_21-Day_Elimination_Diet_Meal_Plan\"><\/span><b>What Is the Perfect 21-Day Elimination Diet Meal Plan?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The perfect meal plan for an elimination diet should be balanced and nutritious, even when certain foods are removed. When embarking on an elimination diet, it\u2019s important to maintain a complete and balanced diet. This process can be confusing as many of the foods you consume daily are likely to be eliminated. Therefore, having the guidance of a healthcare professional could be quite helpful for navigating this path effectively.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">It\u2019s essential to enjoy a balanced diet with the foods you can consume. You should prioritize <a href=\"https:\/\/betterme.world\/articles\/protein-and-fiber-foods\/\">protein<\/a> sources that fit your diet type, whether through lean meats, eggs, or plant-based alternatives. In addition, don\u2019t forget to fill your plate with colorful fruits and vegetables &#8211; each color on your plate represents different vitamins, minerals, and fiber that are important for your health.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Healthy fats also play a crucial role in your nutrition. Incorporating olive oil, avocados, and seeds can be beneficial, and in most elimination diets, these options are commonly allowed.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Most importantly, a perfect elimination diet plan should ensure that you maintain adequate nutrition despite the restrictions.

This approach helps identify foods that may cause intolerances and can bring symptom relief. Many people report improvements in their energy and overall well-being by the end of the process.<\/span><\/p>\n<ul><li><h3><span class=\"ez-toc-section\" id=\"Can_I_have_coffee_on_an_elimination_diet\"><\/span><strong>Can I have coffee on an elimination diet?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3><\/li><\/ul><p><span style=\"font-weight: 400;\">The answer depends on the version of the elimination diet you\u2019re following. In many types of this diet, coffee is allowed as long as it doesn&#8217;t contain additives. However, other types of diets suggest avoiding it due to its potential to cause irritation in the digestive system. It&#8217;s important to listen to your body and pay attention to how you feel when consuming it.<\/span><\/p>\n<ul><li><h3><span class=\"ez-toc-section\" id=\"Can_you_eat_bananas_on_an_elimination_diet\"><\/span><strong>Can you eat bananas on an elimination diet?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3><\/li><\/ul><p><span style=\"font-weight: 400;\">Yes, bananas are generally acceptable on an elimination diet. They are an excellent source of energy and nutrients, which makes them a healthy option. However, it\u2019s always advisable to check the specific guidelines of the diet you\u2019re following. For example, ripe bananas are considered high in FODMAPs and may be limited on a low-FODMAP diet.<\/span><\/p>\n<ul><li><h3><span class=\"ez-toc-section\" id=\"Can_I_lose_7_lb_in_21_days\"><\/span><strong>Can I lose 7 lb in 21 days?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3><\/li><\/ul><p><span style=\"font-weight: 400;\">It\u2019s possible to lose 7 pounds in 21 days, particularly if you combine a reduced-calorie diet with regular exercise, but it\u2019s an ambitious goal. Results may vary depending on metabolism and personal commitment. The key is to maintain a healthy and sustainable approach. The goals of an elimination diet are symptom relief and identification of trigger foods, not weight loss. There are much healthier and more sustainable ways to lose weight if that\u2019s your primary goal.<\/span><\/p>\n\n<\/span><\/p>\n<p><span data-sheets-root=\"1\"><a href=\"https:\/\/quiz.betterme.world\/en\/first-page-generated-gender?flow=2196&amp;utm_source=Blog&amp;utm_medium=Blog&amp;utm_campaign=21-Day_Elimination_Diet\" target=\"_blank\"><video autoplay=\"autoplay\" loop=\"loop\" muted=\"muted\" playsinline=\"playsinline\" width=\"777\"><source src=\"https:\/\/cdn.betterme.world\/articles\/wp-content\/uploads\/2023\/06\/ezgif.com-gif-to-mp4-1.mp4\" type=\"video\/mp4\" \/><\/video><\/a><\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"The_Bottom_Line\"><\/span><b>The Bottom Line<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The 21-day elimination diet is an approach that is designed to identify foods that could cause adverse reactions. For three weeks, certain food groups are eliminated to observe how the body responds. This process helps detect intolerances and can also foster a greater awareness of eating habits.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Elimination diets will vary based on your healthcare provider\u2019s instructions, but often dairy, gluten, added sugars, and ultra-processed foods are excluded, while fruits, vegetables, lean proteins, and gluten-free grains are included. The first stage focuses on elimination, preparing the ground for the controlled reintroduction of foods.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In summary, a good 21-day elimination diet should focus on both what is eliminated and what is included, helping improve the relationship with food and its effect on health.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>On the journey toward healthier eating, some people may find themselves dealing with symptoms such as fatigue, digestive issues, or allergic reactions (1).
