Whole30 Diet

Whole30 Diet

Whole30 is a month-long diet plan aimed at promoting a healthy lifestyle by eliminating a range of common foods in our diets. The diet is based on the premise that there are certain foods in our daily diet that can be harmful to our health, and cutting them off can make us healthier.

The foods in this category include sugar, grains, alcohol, legumes, dairy, and certain food additives.

The Whole30 diet program was created by nutritionists Dallas and Melissa Hartwig in 2009, when they wrote The New York Times bestseller, It Starts with Food. The program was promoted as a way to reset your metabolism and restructure your relationship with food.

During the one-month duration, followers will eat whole, unprocessed foods like vegetables, fruits, healthy fats, animal protein, and nuts. After the 30 days, you will gradually reintroduce the forbidden food groups to check for reactions.

The diet plan has been the topic of debate for some time now as some critics believe it is another unsustainable diet fad, even though followers believe that it can enhance different aspects of our health.

How does the Whole30 diet work?

The idea behind the program is simple – just completely eliminate foods that may harm your health for a period of four weeks. Once the initial four weeks have elapsed, gradually reintroduce the foods you miss, while looking out for how your body responds to them.

You will be subjected to following a set of simple but strict rules. For the next 30 days, you will be given a list of allowed foods as well as off-limit foods, which you will strictly adhere to as going off-track means starting all over again from day one.

The founders believe that strict adherence enables your body to reset in isolation of certain foods that may cause hormone imbalances, inflammation, or gut disruptions. Unlike other diets, Whole30 doesn’t require calorie tracking, portion measurements, or point counts.

Also, taking body measurements and weight is strictly reserved only for the first and last days of the program.

What are the benefits of the Whole30 diet?

While most people follow the Whole30 diet plan in the hopes of losing weight, the program is also believed to help in the following areas

  • Balancing the immune system
  • Healing the digestive tract
  • Improving medical conditions
  • reduced food craving
  • Higher energy levels
  • Improved sleep
  • Change your thoughts and attitude towards food

What foods are accepted in the program?

Followers are allowed to eat whole, unprocessed, and minimally processed foods such as:

  • Fruits: All types, both fresh and dried, but fresh fruits are preferable.
  • Eggs: All types of eggs, including meals made from them like homemade mayo
  • All types of vegetables
  • Fish and seafood: Fish, calamari, anchovies, crab, lobster, shrimp, etc.
  • Meat and poultry: Veal, beef, duck, chicken, duck, turkey, pork, lamb, etc
  • Some fats: Coconut oil, duck fat, plant oils, clarified butter and ghee.
  • Seeds and nuts: All types of seeds and nuts besides peanuts, which are technically legumes. Nut flours, nut butter, and nut milk are allowed.

If you must use minimally processed foods, the program encourages you to go for those with the shortest ingredient lists that only contain ingredients you know.

What foods are off-limits?

The following foods must be eliminated during the course of the diet.

  • All types of spirits, liqueurs, wines, and beer
  • Sugar and artificial sweeteners: Honey, raw sugar, agave syrup, maple syrup, as well as all products containing these sweeteners and other artificial sweeteners.
  • Soy: all including edamame, tofu, tempeh, and all products derived from soy, including miso and soy sauce.
  • Regardless of how they were processed, all grains are to be avoided, including corn, rice, wheat, and oats.
  • Processed additives: These include MSG, sulfites, or carrageenan. Foods containing any of these ingredients should be avoided.
  • Legumes and pulses: Most peas, beans, and lentils, as well as peanut butter, should be avoided. Exceptions include sugar snap peas, green peas, and snow peas.

Also, the diet restricts you from recreating your favorite baked goods, treats, and snacks – even with Whole30-approved ingredients. So, foods like paleo pancakes and cauliflower pizza crust must be avoided.

Other additional rules

The Whole30 program also recommends some extra rules that are not related to diet. For instance, smoking is not allowed for the duration of the diet.

You are also forbidden from partaking in any form of body measurement or step on a scale on any other day other than the first and last days. The reason for these additional rules is that the Whole30 diet is about more than just weight loss.

Adhering to these rules is promoted as a way to reset your mindset and encourage long-term health.

What happens next: the reintroduction stage

Once you’ve successfully completed the four weeks, you can then move on to the second phase of the program, which is the reintroduction stage.

In the stage, certain foods will be slowly reintroduced into your diet to evaluate how they react to your health in areas like your immune system, digestive tract, healthier metabolism, and your relationship with food.

The recommended way to reintroduce these restricted foods is to add back only one food group at a time. For instance, you can introduce eggs on day one. You are then encouraged to resume the Whole30 diet and avoid eggs on days two to four while looking out for any potential symptoms.

If all goes well, you can then reintroduce a new food group on day five and repeat the process. The idea behind this gradual reintroduction process is that it will help you better identify which foods can cause harmful symptoms such as skin breakouts, bloating, or achy joints.

Once you have successfully tested every food group, those that didn’t have adverse effects on your well-being can be added to the diet. Naturally, you are not required to reintroduce all the foods. In fact, you are encouraged only to reintroduce foods that you miss.

What are the potential adverse effects of the Whole30 program?

There are some aspects of this diet plan that are in line with a nutritious diet. For instance, the diet encourages consuming minimally processed foods and a high intake of fresh vegetables and fruits.

However, avoiding nutrient-packed foods like soy, dairy, and legumes may make it more challenging to meet all your daily nutrient recommendations, which may result in adverse health effects if continued for more than four weeks.

Also, the diet was created by expert sports nutritionists who take on a tough-love approach in making sure people keep up with the plan. While these may be seen as an effective way to ensure strict compliance, some people see it as off-putting and may not be able to sustain the diet over time.

Is the Whole30 diet right for you?

That depends on your motive for wanting to try the diet plan. The Whole30 diet program is not a simple diet plan that someone can ease into over long periods. Since it’s a 30-day full commitment program, it may not be right for everybody.

The program itself is very restrictive; if you slip up once, or have a cheat meal, you will need to start over from day one, even if you were on your 29th day. This alone is an obstacle unless you can discipline yourself for the whole 30-day duration.

In addition, a lot of time is also spent on preparing for the diet. Since the diet eliminates certain food groups, you may have to spend ample time planning drafting out a meal plan and actually preparing them yourself for the next 30 days. While this may be great for people who love cooking, it can be overwhelming for others.

Ordering meals and eating out at restaurants will also be complicated due to the strict nature of the program. You also have to plan ahead for your on-the-go snacks as any snack that falls into the category of junk foods are off-limits.

It is a widely known fact that a calorie deficit is required for weight loss. So even though the Whole30 diet is not promoted as a weight loss program, it may likely help you create the calorie deficit needed to shed a few extra pounds.

However, if you discontinue the food choices you made on this diet, you may not be able to sustain the weight loss in the long term.

As for the potential benefits, there is no scientific evidence available to back the claims. There is also no strong reason to restrict grains, legumes, or dairy.

Nevertheless, some individuals may indeed suffer from food intolerances that they don’t know about, which the diet reintroduction stage can help identify.

Overall, if you’re looking to completely reset your relationship with food, this diet may be beneficial. But if you’re looking to improve your diet and overall well-being, you are better off trying out other diet programs.


Whole30 is a diet program that is meant to last for four weeks. During this period, you’re required to eliminate certain food groups and only consume minimally processed and whole foods. While the diet is promoted to have several health benefits, these claims haven’t been evaluated by the relevant authorities.

The program does have its own benefits, such as helping you identify foods that may cause certain problems, and some people have claimed it helped them lose weight. However, it is not a weight loss program, but it is aimed at giving your body a reset and allowing it to recover from the harmful effects that certain foods have on your health.

Due to its restrictive nature, the program is only recommended for people who have a high level of self-discipline and can stick to the plan for the whole duration without cheating a meal, and those who love spending time making their own meals at home.

If you’re looking to try out the program, make sure to familiarize yourself with the rules of the diet plan before you begin. To make the transition easier, start reading food labels to identify foods that are not permitted in the program and slowly wean yourself off some of the foods that may be addictive, such as sugar and alcohol.

It is also crucial to note that the Whole30 program is not a long-term diet. Therefore, once the 30 days are up, it is essential to switch to a more healthful and balanced long-term diet plan than the Whole30 diet.
