The 21-day diet
Dr. Oz's 21-Day Diet is a weight-loss program that involves eating three meals and two snacks per day, drinking lots of water, and consuming specific foods. The diet recommends eating plant proteins, non-starchy vegetables, and healthy fats, while eliminating sugar, artificial sweeteners, and processed foods. Dr. Oz also suggests drinking two cups of oolong tea daily, claiming that it boosts metabolism and increases mental alertness.
The diet is flexible and does not require packaged foods or meals. It encourages cooking your own meals and includes a long grocery list with various foods to fit all taste buds. It also recommends finding a "'weight-loss buddy'" for support and accountability.
On the 21-Day Diet, you can eat unlimited non-starchy vegetables for lunch, dinner, and snacks. Dr. Oz provides a list of 42 permitted vegetables, including some root vegetables like beets and turnips. The diet also suggests three servings of plant-based proteins per day, such as half an avocado and legumes. It allows for one serving of whole grains and two servings of fruit per day. Healthy fats, such as olive oil, nuts, and nut butter, are also included in the diet.
In addition to the specific foods, the 21-Day Diet also emphasizes exercise. It recommends 30 minutes of cardiovascular activity per day, such as walking, and strength training once a week to build muscle. The goal is to eventually work up to 10,000 steps or about 5 miles per day.

Intermittent fasting
Eating within a smaller time window allows your body to burn off all the blood sugar in your system, at which point it starts turning stored fat into ketones to use as fuel. This is similar to the process that occurs when people go on the keto diet, but with Dr. Oz's approach, you can still enjoy carbohydrates. Research from the National Institutes of Health and Johns Hopkins University also shows that this style of eating makes cells stronger, providing a significant overall health boost.
Dr. Oz's System 20 Diet is a comprehensive, science-based health plan that focuses on improving various aspects of wellness, including diet, sleep, and exercise. The diet includes specific guidelines for meals and snacks, with a focus on lean protein, legumes, non-starchy vegetables, fruit, whole grains, and healthy fats. It also incorporates cheat days and allows for cocktails, which have been shown by Cornell researchers to shock the body's system and boost metabolism.
In addition to dietary changes, the System 20 plan also recommends altering your morning routine, setting realistic goals, and working on de-stressing and connecting with others. Dr. Oz emphasizes the importance of finding a buddy to accompany you on your health journey, as social connection is a crucial aspect of the plan.
