Whole30

Whole30 is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Whole30 rather than just read about it. In short: The Whole30 is a 30-day elimination fad diet that emphasizes whole foods and the elimination of sugar, alcohol, grain, and dairy. The traditional Whole30 also eliminates legumes and soy, while a plant-based version of the Whole30 allows consumption of those food groups.

Key takeaways

  • Whole30 belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Whole30 to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Whole30 from memory before moving on to harder problems.

Reference excerpt

The Whole30 is a 30-day elimination fad diet that emphasizes whole foods and the elimination of sugar, alcohol, grain, and dairy. The traditional Whole30 also eliminates legumes and soy, while a plant-based version of the Whole30 allows consumption of those food groups. The traditional Whole30 is similar to but more restrictive than the paleo diet, as adherents may not eat natural sweeteners like honey or maple syrup. There is no scientific evidence to support health claims made by Whole30 and limited independent research has been conducted on the diet.

Description Foods allowed during the traditional Whole30 program include meat, nuts, seeds, seafood, eggs, vegetables, and fruits. During the Whole30, participants are advised not to count calories or to weigh themselves. After the program is complete, participants are counseled to strategically reintroduce foods outside the endorsed Whole30 list, document the health consequences and culinary value of these additions, and determine whether the addition is desired. The program's founders believe that sugar, grains, dairy, alcohol, and legumes may affect weight, energy, and stress levels. Losing weight is not a focus of Whole30; calorie-counting and weigh-ins are not allowed.

History The program was created by then wife and husband Melissa (Hartwig) Urban and Dallas Hartwig in April 2009. They both became certified sports nutritionists; he worked as a physical therapist, and she was working at an insurance company during the day and doing nutritional consulting in her spare time. She quit her job to run the Whole30 business in 2010. They co-authored It Starts with Food (2012) and The Whole30: The 30-Day Guide to Total Health and Food Freedom (2015). They separated in 2015. Melissa (Hartwig) Urban took over the business, and published Food Freedom Forever: Letting Go of Bad Habits, Guilt, and Anxiety Around Food in 2016. In July 2016, a New York Times article on use of Instagram by dieters noted that participants in the Whole30 program had shared over one million Instagram posts using the #Whole30 hashtag, and noted that those sharing the tag were "one of seemingly endless like-minded communities," comparing it with the over 3.5 million posts under the #WeightWatchers hashtag. As of 2018, the "Whole30" trademark had been licensed to Applegate, Blue Apron, Whole Foods Market, Snap Kitchen, and Thrive Market.

Reception No studies that specifically look into the health impacts of the Whole30 had been conducted as of 2019. While most dietitians generally agree with the program's emphasis on proteins, vegetables and unprocessed foods and the avoidance of added sugars and alcohol, some also view the diet as too extreme. The diet ranked last among 38 popular diets evaluated by U.S. News & World Report in its 2016 Best Diets Rankings; one of the raters, dietitian Meridan Zerner said: "We want behavioral changes and dietary changes that are slow and progressive and meaningful." David L. Katz said of the diet: "The grouping [of banned foods] is both random, and rather bizarre from a nutrition perspective. If the idea is good nutrition, cutting out whole grains and legumes is at odds with a boatload of evidence." It was selected as one of the worst health trends for 2013 by Health magazine. In 2017, the diet was ranked last (out of 38 diets) by U.S. News & World Report on account of its extremely restrictive nature and likely adverse effects on a dieter's social life. In 2018, the Whole30 was ranked 37th out of 40 by U.S. News & World Report, and in 2019, it was ranked 38th out of 41.

Worked examples

Example 1 — a first encounter with Whole30

Start with the simplest possible case. Write down what Whole30 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Whole30 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Whole30 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Whole30

In research
Whole30 appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Whole30 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Whole30 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Diets, Fad diets, Gluten-free diet, so understanding it makes those chapters shorter.
In everyday life
Look for Whole30 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Whole30 in simple terms?

The Whole30 is a 30-day elimination fad diet that emphasizes whole foods and the elimination of sugar, alcohol, grain, and dairy. The traditional Whole30 also eliminates legumes and soy, while a plant-based version of the Whole30 allows consumption of those food groups.

Why does Whole30 matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Whole30?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
