The Whole30: A 30-Day Diet for Better Health?
The Whole30 diet is a viral health movement that's increasing in popularity.
It encourages followers to cut out alcohol, sugar, grains, legumes, dairy and additives from their diet for 30 days, and is advertised as a total lifestyle change.
Followers rave about its health benefits, while critics claim that it's just another unsustainable diet fad. So does it work and should you try it?
This article explains everything you need to know about the Whole30 diet.
What Is the Whole30 Diet?
The Whole30 diet is a month-long clean-eating program that promises a variety of health and emotional benefits.
It was developed in 2009 by two certified sports nutritionists who promoted it as a way to reset your metabolism and reshape your relationship with food.
The diet focuses on the idea that certain food groups may negatively affect your health and fitness.
Therefore, eliminating these foods from your diet is supposed to help your body recover from the negative effects and promote long-term health.
Most people seem to follow this diet in hopes of losing weight.
However, some may also use the program to identify food intolerances or achieve some of its proposed health benefits.
SUMMARY:
The Whole30 diet is a month-long eating program that aims to help you lose weight, improve your relationship with food and achieve long-term health.
How to Follow the Whole30 Diet
The idea behind the Whole30 program is simple — just completely cut out foods that may harm your health for a period of 30 days.
After the initial 30 days, slowly reintroduce the foods you miss, while monitoring the effects they have on your body.
The diet has a strict set of rules.
It also provides you with a list of allowed foods, as well as a list of off-limit foods. During the month-long elimination period, no cheating is allowed.
Going off-track entails starting the challenge over from day one.
The founders claim that strict adherence allows your body to reset in isolation of certain foods that may cause inflammation, gut disruptions or hormone imbalances.
Unlike other diets, there is no need to track calories, measure portions or count points. Also, weighing yourself is strictly reserved for days 1 and 30 of the program.
SUMMARY:
Following the Whole30 diet involves eating as much as you'd like, while avoiding certain foods for a period of one month.
Proposed Benefits of the Whole30 Diet
Following the Whole30 diet perfectly for 30 days is said to have many health benefits.
These include fat loss, higher energy levels, better sleep, reduced food cravings and improved athletic performance.
What's more, the diet's founders promise it will change the way you think about food, as well as your taste.
Proponents of the diet further claim that it can alter the emotional relationship you have with food and your body.
Although these claimed benefits may appear very attractive, it's worth keeping in mind that there are currently no scientific studies backing them up.
SUMMARY:
The Whole30 diet is claimed to provide you with physical and psychological health benefits above and beyond simple weight loss.

Foods to Avoid
During the 30-day diet, certain foods must be completely eliminated. These include:
Sugar and artificial sweeteners: Raw sugar, honey, maple syrup, agave syrup and all products containing these sweeteners, as well as artificial sweeteners.
Alcohol: All types of beer, wines, liqueurs and spirits.
Grains: Regardless of their degree of processing, all grains, including wheat, corn, oats and rice, are to be avoided.
Pulses and legumes: Most peas, lentils and beans, including peanut butter, should be avoided. Green beans, sugar snap peas and snow peas are exceptions.
Soy: All soy, including tofu, tempeh, edamame and all products derived from soy, such as miso and soy sauce.

Processed additives: These include carrageenan, MSG or sulfites. Any food or beverage containing these ingredients should be avoided.
In addition, the diet recommends that you avoid recreating your favorite baked goods, snacks or treats — even with Whole30-approved ingredients.
Thus, foods such as cauliflower pizza crust and paleo pancakes must be avoided.
There's also no such thing as a cheat meal on this diet. Instead, you're encouraged to adhere strictly to the guidelines all the time. If you do slip up, the diet's founders strongly encourage you to begin the whole program again from day one.
SUMMARY:
The Whole30 diet eliminates sugar, alcohol, grains, legumes, soy, dairy and processed foods for a 30-day period.
A Few Additional Rules
The Whole30 diet encourages some additional rules that are not related to diet.
For instance, smoking is forbidden for the duration of the diet.
You're also not allowed to step on the scale on any days other than days 1 and 30, or partake in any form of body measurements.
The justification behind these additional rules is that the Whole30 program is about more than just weight loss.
Following these rules is promoted as a way to change your mindset and promote long-term health.
SUMMARY:
The Whole30 diet is promoted as more than a simple weight loss diet. Therefore, you are encouraged to avoid smoking and weighing yourself for the duration of the program.
Life After Whole30: The Reintroduction Phase
Once you've successfully completed the Whole30 program, it's time to focus on step 2 — the reintroduction phase.
In this phase, certain foods will be slowly reintroduced to evaluate how they make you feel in regard to your healthier metabolism, digestive tract, immune system and relationship with food.
The suggested way to reintroduce off-limit foods is to add back only one food group at a time. For instance, milk can be reintroduced on day 1.
You are then encouraged to return to the Whole30 diet and avoid milk on days 2–4, while paying attention to any potential symptoms.
If all goes well, a different food group can be reintroduced on day 5, repeating the process.
Reintroducing only one food group at a time while keeping the rest of the diet the same is promoted as a way to better identify which foods cause negative symptoms, such as bloating, skin breakouts or achy joints.
Once all food groups have been individually tested, those that were well-tolerated can be added back into the diet.
Naturally, individuals are not required to reintroduce all foods. In fact, they're strongly encouraged to avoid reintroducing foods that they do not miss.
SUMMARY:
After the initial 30 days, you may slowly reintroduce off-limit foods to see how they affect health and fit into your new eating pattern.

Potential Negative Effects of the Whole30 Diet
Several aspects of the Whole30 program are in line with a nutritious diet.
For instance, the diet promotes consuming minimally processed foods and a high intake of fresh fruits and vegetables.
However, avoiding nutrient-rich foods like legumes, soy and dairy may make it more difficult to meet all your daily nutrient recommendations (1Trusted Source).
This may create negative health effects if the diet is continued for more than 30 days.
In addition, although rigid rules can be a good way to reset eating habits for some people, restrictive diets with no allowance for indulgences are generally not sustainable over time (2Trusted Source).
Those contemplating following this diet in the long term are encouraged to record their meals for a couple days in an online diet journal such as Cronometer.
This can help ensure that daily nutrient recommendations continue to be met.
SUMMARY:
The restrictive nature of the Whole30 diet may make it difficult to meet daily nutrient recommendations or sustain the diet in the long term.
Should You Try the Whole30 Diet?
It's a well-known fact that a calorie deficit is needed for weight loss (3Trusted Source, 4Trusted Source, 5Trusted Source).
Because of its restrictive nature, the Whole30 diet will likely help create the calorie deficit you need to shed some extra pounds.
However, unless the food choices you make on this diet become a habit, the weight loss you experience may not be sustainable in the long term (2Trusted Source).
As for the supposed benefits, there are no scientific studies available to support the claims. There's also no strong reason to restrict dairy, grains or legumes (6Trusted Source, 7Trusted Source, 8Trusted Source).
Nevertheless, it is true that some people may unknowingly suffer from food intolerances, which the diet's reintroduction phase can help identify (9Trusted Source).
Overall, this diet may be helpful if you want to completely reset your eating habits.
But if you're simply looking to improve your diet and overall health, you're better off trying a whole foods diet like this one instead.
