Choosing Between Paleo, Keto, Whole30, Vegan, & Clean Eating Diets
Are you confused about which healthy diet to choose? This article shares some of the differences between clean eating, paleo, Whole30, keto, and plant-based diets. Use this information to help determine which diet will work best for you.
Choosing a Diet Plan
It can be confusing to figure out which diet plan will work best for you. The United States Department of Agriculture (USDA) is in charge of offering nutrition advice to Americans. The USDA promotes the “My Plate” format for the basis of a healthy diet.
But, many people have dietary restrictions, food allergies, and specific health conditions that may be helped by specialized diets that restrict certain macronutrients, food groups, or foods.
And, women need to be particularly mindful about dieting, as women of reproductive age especially need to ensure adequate intake of iron-rich foods, calcium, and vitamin D.
Some of the specialty diets that have developed to address both health concerns and weight management include clean eating, paleo, Whole30, plant-based, and keto.
This article will explore each of the popular diet plans and point out their main differences to help you determine which one might be best for you. As always, it’s best if you discuss this with your healthcare provider, as he or she can help figure out exactly which diet will work best for your specific situation.

Clean Eating Diet
Clean eating is less of a diet and more of an overall eating philosophy. Clean eating is generally described as including real, whole foods most of the time, choosing organic and sustainable options whenever possible. Clean eating also means selecting foods that meet one’s individual needs.
People following a clean eating diet are advised to eat minimally processed foods and be more mindful of how their food is sourced. A clean eating diet is considered to be healthy because of its elimination of processed foods and its focus on eating real, whole foods. Check out my clean eating food list.
The benefits of a clean eating approach are that it is flexible and allows for individuality. Women who follow a clean eating diet don’t have to feel overly restricted. And, people who “eat clean” can easily adapt the diet to meet their individual needs without feeling like they have failed at it.
Other types of general “clean eating diets” can include the Mediterranean diet, anti-inflammatory eating, and real food diets.
The main drawback of a focus on clean eating is that it may lead to disordered eating patterns in some women. The fixation on eating only unprocessed foods is referred to as orthorexia, and is a recognized type of eating disorder.
A clean eating diet can also be more expensive than that Standard American Diet, as it eliminates fast foods and processed foods. Read my tips on how to eat clean on a budget.
So, while clean eating is a flexible approach to dieting, it may work best if the participant works with a dietitian or nutritionist who can help keep her in the right mindset, especially if she has a history of disordered eating.
A paleo diet is more specific and restrictive than a clean eating diet, because it is both gluten-free and dairy-free, with no refined sugars or processed ingredients. The paleo diet also excludes legumes and grains.
The paleo diet is a diet that focuses on foods that humans ate before agriculture was invested. In other words, paleo foods include those that could be hunted and gathered, including meats, eggs, fruits, vegetables, nuts, and seeds.
Proponents of the paleo diet claim that it can improve your health by eliminating processed foods and increasing the intake of fruits and vegetables for more phytonutrient and fiber consumption.
People who follow a paleo approach can lose weight and improve their health markers because they are eliminating inflammatory, highly refined and overly processed foods. A paleo diet is often recommended for autoimmune disease because it avoids the worst foods for Hashimoto’s, as an example.
People who oppose the paleo approach do so because this way of eating can be very restrictive. Other criticisms of the paleo diet are that it can be expensive, it can be time-consuming to prepare foods from scratch, and that is is too high in meat consumption.
A paleo approach is not necessarily low-carb, although some people mistakenly believe it to be so. Carbohydrate sources on a paleo diet include sweet potatoes, fruits of all types, and other starchy vegetables like carrots. Some less strict paleo dieters even include white rice, white potatoes, and legumes as part of their diet.
Whole30 is very similar to paleo, but with even more restriction on the types of foods allowed and the addition of mindset shifts. The Whole30 approach differs from paleo in that is allows white potatoes. But, Whole30 is similar to paleo in that it eliminates all grains and legumes.
A paleo diet can include some alcohol and sugars, a Whole30 diet does not.
The Whole30 diet has gained somewhat of a cult following in the past several years. It’s essentially a more restrictive version of the paleo diet that is to be implemented for a minimum of 30 days. The “rules” are set out in the Whole30 book.
In addition to being instructed to avoid things that our paleolithic ancestors didn’t eat, the Whole30 diet also excludes anything that resembles things that our paleolithic ancestors couldn’t hunt or gather in the wild. This means no paleo pancakes, muffins, chips, bars, etc.
The pros and cons of the Whole30 approach are very similar to those of the paleo approach. Critics of Whole30 say that it’s not convenient, it can be expensive, it excludes all alcohol, and it’s time-consuming since almost every food has to be prepared at home.
Also, the Whole30 diet plan is not recommended for anyone who has a history of disordered eating, as the restrictive nature of the plan can trigger over-restriction and unhealthy patterns.
While there are no studies looking at the positive or negative effects of the Whole30 diet, the Cleveland Clinic supports its use for some people.
The ketogenic diet, also known as high-fat, low-carb, has been dramatically increasing in popularity over the past few years.
The concept behind this diet is to restrict carbohydrates and increase fat intake. A general rule is to get at least 70% of your calories from fat. Keto dieters are also told to stay below 50 grams of carbs per day, and those with a significant amount of weight to lose are instructed to stay at or below 20 grams of carbs per day.
Some people who follow a ketogenic diet choose not to consume carbs at all. Others include a carb-up practice where they may eat a piece of fruit or a sweet potato every few days.
A keto diet may be similar to paleo, but it does not restrict dairy. So, a keto diet is more focused on blood stabilization and weight loss where paleo and Whole30 diets may be more focused on reducing food allergies and lowering inflammation.
However, criticism of the keto diet include that it can cause severe nutritional imbalances, requires medical supervision, is too rigid, and is too difficult to sustain.
As with all types of restrictive diets, people who have a history of eating disorders should proceed very cautiously when thinking about doing an ultra-restrictive diet such as keto. Additionally, there are groups of people including children and pregnant women who are not advised to do a keto diet.
Vegan and plant-based diets have become very popular over the last 10 or so years. A plant-based diet is one that eliminates all animal products. A vegan diet is even more restrictive in that vegans do not own clothes or other products that have come from animals.
Vegan or plant-based dieters do not eat fish, chicken, red meat, eggs, dairy products, or even honey. Some people on a plant-based diet also eliminate oils, even those that come from plants.
Plant-based and vegan diets have been shown to reduce the risk of heart disease and certain cancers. And, the American Dietetics Association says that an appropriately planned vegan or vegetarian diet can be safe for all stages of life.
However, a vegan diet is not right for everyone. Some people who follow a vegan diet can become deficient in certain nutrients including vitamin B12, calcium, and iron. Read more about the potential plant-based diet dangers.

As with all restrictive diets, a plant-based diet is no different in that it can lead to disordered eating patterns, especially in women. So, it may be helpful to work with a dietitian or nutritionist to help make sure you are getting all the nutrients you need on a vegan or plant-based diet.
As you may have gathered from reading this article, adopting a dieting mentality can be dangerous for those who have struggled with an eating disorder in the past. There is also not one diet that is perfect for everyone, or even for a person throughout her whole life.
Restricting whole categories of foods or macronutrients can lead to obsessive behavior surrounding food. It may be helpful for some people, and especially for women who have a history of disordered eating, to not limit themselves to one particular diet style.
Rather, it may be more helpful and sustainable over the long run to focus on eating more whole foods and fewer processed foods. As long as you are making food choices that nourish you and make you happy, you are on your way to freeing yourself of dieting mentality.
The purpose of this article was to review the major healthy eating diets that are popular right now, including clean eating, paleo, Whole30, keto, and plant-based. After comparing and contrasting each diet, we also determined that some women may be better off by not following a specific diet, but by simply choosing more whole foods and fewer processed foods.
