It aims to fix unhealthy eating habits, improve digestion, boost energy levels, and foster a deeper understanding of how food impacts our body. In this article, we discuss everything about how this diet works, its benefits, and potential side effects. Continue reading.

What Is The Whole30 Diet?

The Whole30 diet is a 30-day restrictive dietary program designed to identify and restrict the consumption of foods that may cause inflammatory and gastrointestinal discomfort, skin problems, cravings, and energy fluctuations. Two sports nutritionists, Melissa Hartwig Urban and Dallas Hartwig, created this diet in 2009. It is a highly restrictive diet plan that excludes commonly problematic foods such as gluten-containing grains, processed sugar, and soy for 30 days to allow your body to recover from their negative effects and repair itself. Participants are encouraged to reintroduce the excluded foods after 30 days, one at a time, to understand how they affect their health and well-being.

Did You Know?

The #Whole30 hashtag was used in over 4 million Instagram posts by Whole30 participants.

The simple strategy of the Whole30 diet has made it popular among millions. Let us explore how this diet works in the next section.

How Does The Whole30 Diet Work?

The Whole30 diet is not a long-term plan. It is a quick reset strategy that can help you find potential food sensitivities and create a better relationship with food. Here is how it works:

• During the 30-day elimination period, you need to stop consuming dairy products, foods with added sugars or a high amount of preservatives, and other common foods that may cause allergies.
• You will instead take more whole foods like fresh fruits, vegetables, and healthy fats, and moderate amounts of lean protein.
• You must strictly adhere to the program’s rules to enjoy the benefits. This is one reason the diet does not allow any ‘cheat days’. This is one of its key principles.
• After 30 days, you can gradually reintroduce the problem foods one at a time. Consume them for a few days and stop their intake to observe your body’s response. This can help you identify specific triggers that cause discomfort.

Note: Always consume Whole30-approved foods and read product labels of packages to ensure they contain no prohibited ingredients.

Did You Know?

Celebs like Elizabeth Jean “Busy” Philipps, the American actress, shared her experience with this diet in her Instagram stories and brought attention to the program.

The Whole30 diet is restrictive and follows a strict protocol. But if you can stick with it, you get to experience several benefits. We discuss the same in the following section.

Whole30 Diet Benefits

• May Promote Body Fat Reduction: The fruits and vegetables and mono- and polyunsaturated fats in the diet may help promote body fat reduction. Trained CrossFit individuals could lose body fat and gain fat-free mass with the Whole30 diet (1). Also, the dietary fiber in fruits and vegetables may help with fat loss and weight loss (2).
• May Provide Better Sleep: This diet plan allows all nuts and nut butters. These contain antioxidants like serotonin, melatonin, and polyphenols that may help improve sleep quality (3).
• May Improve Digestion: The fruits and vegetables (leafy greens) in the diet are high in dietary fiber that may help improve digestive health (4).
• May Reduce Cravings: The fruits and healthy fats in the diet may help reduce cravings as they both may promote feelings of fullness (5).
• May Increase Energy: The intake of tree nuts, which are rich in vitamins, flavonoids, and mono- and polyunsaturated fats, may help boost energy (6). However, consume nuts in moderation as their excess intake may cause weight gain.
• May Reduce Inflammation: The consumption of anti-inflammatory foods like fruits and vegetables, vitamin C, and mono- and polyunsaturated fats may help reduce inflammation (7).
• May Regulate Blood Sugar Levels:Regular intake of leafy greens can improve glycemic control and may help regulate blood sugar levels (8).

This dietary pattern claims to provide many health benefits beyond weight loss. However, individual experiences may vary, and direct research on the benefits of the Whole30 diet is limited. Hence, consult your healthcare professional before making any changes to your diet.

If you are looking for a diet focussed on weight loss, you may try the 30 Day Shred Diet which is sometimes mistaken with the Whole30 but differs significantly from it. It offers a more structured fitness and nutrition approach and may help support your weight loss goals.

While the Whole30 diet appears quite beneficial, it does eliminate certain nutrient-rich food groups. This restriction may pose risks for some people. Learn further in the next section.

Risks Associated With The Whole30 Diet

The Whole30 diet is very restrictive, and one needs a lot of self-discipline to follow it. While there are no major health risks associated with it, restricting nutrient-rich food groups like dairy or grains, for 30 days, may lead to nutrient deficiencies in some people. Individuals largely dependent on dairy and grains may struggle switching to this diet, and may even experience deficiencies of calcium.

In addition, check with your healthcare professional before starting this diet, especially if you have a history of eating disorders, are already on dietary restrictions, or are taking any medication. You may start this diet once you get a clearance.

Further, avoid this diet if you are pregnant or breastfeeding as it eliminates multiple food groups. A specially designed pregnancy diet is better suited to ensure more balance and flexibility to ensure essential nutrients for both mother and baby.

Planning your meals according to the guidelines of this diet can help you achieve your health and fitness goals. The following 7-day sample diet menu can shed light on what to expect.

• Sugar (artificial sweeteners, honey, raw sugar): Foods with added sugars are full of empty calories. Their excessive intake can cause headaches, cognitive issues, and an increased risk of diabetes and obesity (9), (10). However, more research is warranted in this regard.
• Grains (rice, oats, wheat): Daily intake of cereal grains and wheat products may lead to chronic inflammation in some due to the presence of anti-nutrientsⁱ  Natural or synthetic compounds found in plants and various foods that interfere with nutrient absorption in the body. (11).
• Dairy (milk, cheese, yogurt): Some individuals cannot digest the proteins in milk and end up experiencing gas and bloating (12). In addition, the steroid hormonesⁱ  A class of hormones that plays a key role in various functions within the human body. in milk may lead to tumors in certain people (13).
• Legumes (lentils, soy, beans, peas): Antinutrients such as tannins, lectins, and phytates in legumes are hard to digest and inhibit the absorption of nutrients (14).
• Alcohol (wine and beer):Higher alcohol consumption in the fasting state mainly interferes with glucose metabolismⁱ  A series of chemical reactions which occur within cells and are responsible for converting glucose into energy. and can cause dangerously low blood sugar levels (15).
• Processed Additives(MSG and carrageenan): Monosodium glutamate (MSG) is a flavor enhancer that may cause abdominal pain, headache, and excess sweating (16). Carrageenan is a seaweed extract that may lead to digestive issues (17).

The Whole30 diet is often compared with the Paleo diet as both options seem to include similar foods. However, the two are distinctly different. Learn more in the next section.

Whole30 Diet Vs. Paleo Diet

The Whole30 diet is a restrictive, short-term dietary plan designed for a 30-day reset. But the Paleo diet is a long-term choice that may allow some flexibility. While the Whole30 diet is designed to reset our relationship with food, Paleo is based on the idea that modern humans should include foods in their diet that were available to their prehistoric ancestors. Whole30 is a stricter program than the Paleo diet in terms of the foods it eliminates. For instance, while alcohol is strictly prohibited during the 30-day diet plan, Paleo allows for moderate consumption.

The Whole30 diet is a 30-day restrictive dietary approach designed to eliminate potentially harmful food groups that cause health concerns in some people.

However, it requires a high degree of meal planning and is not suitable for people dealing with eating disorders or following any specific dietary patterns. Hence, it is important to consult your healthcare professional before starting this diet.
