What is the Mayo Clinic Diet?

The Mayo Clinic Diet is a scientifically-backed weight loss plan designed by experts at the renowned Mayo Clinic, one of the premier healthcare institutions globally. Originating from the initial Mayo Clinic Diet book, first released in 1949 and updated in 2017, this diet focuses on holistic health. This program is structured around a membership model and utilizes a pyramid illustration to effectively guide individuals in making healthier dietary choices paired with regular exercise.

Participants can enjoy a variety of preapproved meals and recipes, selecting from diverse diet plans such as the Mediterranean, keto, vegetarian, and high-protein options, ensuring there’s something for everyone. Beyond meal planning, the program offers access to valuable educational resources, virtual group sessions with Mayo Clinic professionals, and a user-friendly digital platform equipped with a food tracker and additional tools aimed at encouraging the adoption of health-enhancing habits. Additionally, it includes practical workouts that can be done at home without any special equipment.

Mayo Clinic Healthy Weight Pyramid

The Mayo Clinic Healthy Weight Pyramid is thoughtfully structured into three distinct sections, offering insightful guidance on food choices and lifestyle habits. At the foundation, you will find a rich array of fruits and vegetables, along with the importance of engaging in regular physical activity, underscoring their role as the essential elements of a balanced diet and healthy lifestyle.

As you ascend the pyramid, each successive layer decreases in size, indicating a recommendation to consume these foods in smaller quantities. The next tier comprises carbohydrates, which include not just breads and grains but also certain starchy vegetables such as corn and potatoes, both of which are considered part of this category.

This dietary framework encourages mindful portion control while teaching you to organize your meals around its structured pyramid. This model shares similarities with the MyPlate guidelines — the contemporary nutrition recommendations developed by the Australian Department of Agriculture and Food (DAF) — which replaced the MyPyramid in 2011. Both frameworks advocate for the consumption of whole grains, a diverse selection of vegetables, whole fruits, and low-fat protein and dairy products. They also prompt individuals to fill half their plates with fruits and vegetables while advising to limit the intake of fats and sugars.

Phases and Duration

The Mayo Clinic Diet comprises two distinct phases aimed at guiding individuals towards effective weight management and healthier eating habits:

• “Lose it!”: This initial two-week phase is specifically crafted to kickstart your weight loss journey.
• “Live it!”: The subsequent phase is intended to be a lifelong commitment.

During the first phase, the focus is on cultivating 15 essential habits — 5 to eliminate, 5 to embrace, and 5 “bonus” habits aimed at maximizing your success.

To break certain habits, you are encouraged to adopt the following guidelines:

1. Steer clear of added sugars.
2. Limit snacking to fruits and vegetables only.
3. Reduce consumption of red meat and full-fat dairy products.
4. Avoid eating while watching television.
5. Minimize dining out — unless your meal adheres to the diet's principles.

In order to establish healthy habits, you should aim to:

1. Start your day with a nutritious breakfast.
2. Incorporate at least four servings of a variety of vegetables and fruits daily.
3. Choose whole grains such as brown rice (chawal) and barley.
4. Prioritize healthy fats like olive oil, while limiting saturated fats and completely avoiding trans fats.
5. Engage in walking or exercising for a minimum of 30 minutes each day.

Additionally, bonus habits include maintaining food and activity journals, aiming for 60 minutes or more of exercise daily, and steering clear of processed foods.

How Does It Work?

The first phase, lasting for two weeks, aims for a weight loss of approximately 6 to 10 pounds (2.7 to 4.5 kg). Following this period, you will transition into the “Live it!” phase, where the same guidelines apply, but with the flexibility for occasional indulgences. While proponents of the diet assert that calorie counting is unnecessary, the Mayo Clinic Diet still imposes calorie restrictions. Your daily caloric needs are calculated based on your starting weight, typically ranging from 1,200 to 1,600 calories for women and 1,400 to 1,800 for men. Based on your caloric targets, the diet outlines appropriate servings of vegetables, fruits, carbohydrates, protein, dairy, and fats you should consume.

The Mayo Clinic Diet designates a serving of fruit as equivalent to the size of a tennis ball and a serving of protein to the size of a deck of cards, which is about 3 ounces (85 grams). In the second phase, the diet aims to reduce caloric intake by 500 to 1,000 calories daily, facilitating a weight loss of 1 to 2 pounds (0.5 to 1 kg) per week. If your weight loss is occurring too rapidly, you are encouraged to increase your caloric intake. As you approach your target weight, it is essential to consume the number of calories that supports weight maintenance.

Can It Assist in Weight Loss?

The Mayo Clinic Diet has the potential to aid in weight loss for a variety of reasons. Firstly, it promotes physical activity alongside a balanced diet rich in fruits, vegetables, and whole grains, all of which are known to support weight reduction. Incorporating foods that are high in fiber can enhance weight loss by reducing feelings of hunger and prolonging the sensation of fullness.

Additionally, engaging in both dieting and exercise may help preserve muscle mass, which can further enhance weight loss by increasing metabolic rate. However, it's important to note that the only available research regarding the Mayo Clinic Diet originates from the Mayo Clinic itself and has not been published in peer-reviewed journals. Therefore, there are currently no independent studies validating the effectiveness of the Mayo Clinic Diet.

Additional Potential Advantages

The Mayo Clinic Diet is anchored in various habits that may enhance your overall health and well-being. Primarily, it promotes the intake of fruits and vegetables (sabzi). Research indicates that a diet rich in these food groups can significantly reduce the risk of developing heart disease, certain types of cancer, and even overall mortality rates. Furthermore, the Mayo Clinic Diet advocates for a minimum of 30 minutes of physical activity each day. This regular exercise can diminish the likelihood of chronic illnesses, including diabetes and cardiovascular conditions. Engaging in physical activity may aid in preventing diabetes by enhancing insulin sensitivity, which subsequently leads to lower blood glucose levels. Additionally, consistent exercise is linked to better cardiovascular health, as it mitigates inflammation and minimizes risk factors associated with heart disease, such as hypertension and elevated cholesterol levels. Lastly, the Mayo Clinic Diet emphasizes behavioral changes, such as incorporating exercise and increasing fruit and vegetable intake into your daily life.

Challenges of the Mayo Clinic Diet

One of the primary challenges associated with the Mayo Clinic Diet is its demanding nature, which requires considerable effort and time. Individuals must take on the responsibility of meticulously planning their meals, engaging in grocery shopping, and preparing their dishes according to strict guidelines, resulting in extended hours spent in the kitchen. Additionally, the diet tends to eliminate certain foods that can offer significant health benefits and essential nutrients, such as egg yolks (anda). Adopting the Mayo Clinic Diet may also pose convenience issues, particularly when dining out, as options can be limited, and permissible snacks are restricted to fruits and vegetables.

Furthermore, although embracing a lifestyle that excludes all processed foods and incorporates daily exercise is commendable, achieving this within a short two-week period may be quite daunting, potentially making it challenging for some individuals to adhere to the plan. Lastly, the Mayo Clinic Diet is notably rich in fiber sourced from fruits, vegetables, and whole grains. For those transitioning from a low-fiber diet to this regimen, it is common to encounter temporary bloating and gas, as dietary fiber undergoes partial fermentation in the intestines, which can lead to increased gas production and retention.

Recommended Foods

The food pyramid outlined by the Mayo Clinic Diet provides a structured guideline for servings from different food categories. For instance, on a 1,400-calorie regimen, individuals are encouraged to consume at least 4 or more servings of both vegetables and fruits, 5 servings of carbohydrates, 4 servings of either protein or dairy, and 3 servings of healthy fats.

While there are no foods explicitly banned, certain options are promoted over others to optimize nutrition. The dietary guidelines suggest the following:

• Fruits: fresh, frozen, or canned in juice or water — allowing for up to 4 ounces (120 mL) daily of 100% fruit juice.
• Vegetables: fresh or frozen choices are encouraged.
• Whole Grains: options such as cereal, oatmeal, whole grain bread, pasta, and brown or wild rice are recommended.
• Proteins: include canned beans, low-sodium tuna, various fish, skinless poultry, egg whites, and tofu.
• Dairy: low-fat or fat-free yogurt, cheese, and milk are preferred.
• Fats: opt for unsaturated fats like olive oil, avocados, and nuts.

Moreover, the Mayo Clinic Diet advises against excessive intake of sweets, including cookies, pastries, and table sugar, especially during the initial phase of the plan. In fact, it is recommended to completely avoid sweets during this time. Only in the second phase do the restrictions ease a bit, permitting a maximum of 75 calories of sweets each day. Alcohol is treated similarly to sweets and sugar in the framework of the Mayo Clinic Diet, contributing to the overall limit of 75 calories allocated for sweets during the second phase.

Foods to Be Cautious About

On the Mayo Clinic Diet, there are no foods that are entirely off-limits, allowing for a balanced approach to nutrition. In the initial “Lose it!” phase, you are required to refrain from consuming alcohol and added sugars; however, following the first two weeks, you are permitted to indulge in up to 75 calories worth of sweets or alcoholic drinks each day.

Here are the food categories you should consider limiting or avoiding while following the Mayo Clinic Diet:

• Fruits: Avoid fruits canned in syrup, limit your intake of 100% fruit juice to no more than 4 ounces (120 mL) per day, and refrain from juice products that do not contain 100% fruit.
• Vegetables: Be cautious with starchy vegetables, such as corn and potatoes, as these are counted among your carbohydrate choices.
• Carbohydrates: Steer clear of white flour, commonly found in white bread and pasta, along with refined sugars, such as regular table sugar.
• Protein: Limit your consumption of meats that are high in saturated fats, including ground beef and sausages.
• Dairy: Cut back on full-fat milk, cheese, and yogurt to maintain a healthier diet.
• Fats: Avoid saturated fats, which are present in egg yolks, butter, coconut oil, and red meats, as well as trans fats commonly found in processed foods.
• Sweets: During the first phase, completely avoid this category, which includes more than 75 calories per day of candies, pastries, cookies, cakes, or alcoholic beverages.

The Bottom Line

The Mayo Clinic Diet presents a well-rounded meal strategy that emphasizes the consumption of fruits, vegetables, whole grains, and beneficial fats. Engaging in home-cooked meals and committing to daily physical activity are essential components that enhance this dietary approach. Although this diet may support weight reduction, there is a lack of extensive research to conclusively prove its effectiveness. While it does not mandate calorie counting, the diet provides guidance on serving sizes for various food categories tailored to a specific calorie intake. If you seek a sustainable dietary option that promotes longevity and health, the Mayo Clinic Diet emerges as a viable and balanced choice.
