3 min read

According to the Mayo Clinic's own analysis, participants in its diet program can achieve an average weight loss of 5.3% of their body weight over six months. For those considering a lifestyle change, the question remains: is the Mayo Diet worth it for your personal health goals and long-term well-being?

Quick Summary

A review of the Mayo Clinic Diet, a two-phase, lifestyle-focused program emphasizing healthy habits, balanced nutrition, and regular exercise for sustainable weight loss and improved overall health.

Key Points

Not a fad diet: The Mayo Clinic Diet is a legitimate, medically-backed program, not a mayonnaise-based fad diet.
Focus on habits: The diet is centered on adopting healthy habits and breaking unhealthy ones, rather than simply restricting calories.
Two-phase approach: It uses a 'Lose It!' phase for initial weight loss and a 'Live It!' phase for long-term maintenance.
Emphasizes whole foods: The program is based on the Mayo Clinic Healthy Weight Pyramid, prioritizing fruits, vegetables, whole grains, and healthy fats.
Requires commitment: While effective, the diet can be demanding and requires significant time for meal planning and preparation.

Understanding the Myth vs. the Medical Program

It's important to differentiate the actual Mayo Clinic Diet from a long-standing fad diet myth. The official program, developed by medical professionals, is an evidence-based, two-phase approach focused on sustainable weight management and overall health, emphasizing fruits, vegetables, and whole grains. The mythical diet, falsely attributed to the Mayo Clinic for years, involved specific foods and was high in protein and calorie-restricted.

The Two Phases of the Mayo Clinic Diet

The program guides participants towards healthier living through two distinct phases.

Phase 1: 'Lose It!'

This initial two-week phase aims to initiate weight loss by helping individuals break unhealthy habits and establish new ones, targeting a loss of 6 to 10 pounds. This involves adopting five healthy habits (like eating a healthy breakfast and exercising) and breaking five unhealthy ones (such as avoiding added sugar and snacking on unhealthy foods). Optional bonus habits include keeping a food journal and increasing exercise time.

Phase 2: 'Live It!'

Designed for long-term health and weight maintenance, this phase focuses on making sustainable changes through mindful eating and portion control, guided by the Mayo Clinic Healthy Weight Pyramid. While calorie counting isn't mandatory, serving recommendations align with target calorie levels. Participants can continue to lose 1 to 2 pounds per week during this phase until their goal is reached.

Core Principles and Food Choices

The diet is structured around a "healthy weight pyramid" that prioritizes foods based on their nutritional value and calorie density. The base of the pyramid, allowing unlimited consumption, consists of fruits and vegetables. The next level includes moderate portions of whole grains. The mid-level focuses on controlled portions of lean protein and low-fat dairy. The top, smallest portion level is for healthy fats and a minimal amount of sweets.

Potential Benefits

Beyond weight loss, the Mayo Clinic Diet offers several health advantages. Its focus on behavioral changes and a long-term perspective supports sustainable weight loss. The emphasis on whole foods and exercise can improve health markers for conditions like diabetes and high blood pressure, and reduce the risk of chronic diseases such as heart disease.

Potential Drawbacks and Considerations

While generally safe, the diet has potential challenges. The initial 'Lose It!' phase can feel restrictive due to the elimination of added sugars and alcohol. The program requires significant time commitment for meal planning and preparation. There's also a cost associated with the optional online program membership. Some individuals may experience temporary digestive discomfort from the increased fiber intake. It's also worth noting that the primary research supporting the diet is from the Mayo Clinic itself, with limited independent studies available.
