Dr. Oz's Ultimate Diet
The diet includes a long list of recommended foods, including fresh fruits and vegetables, lean proteins like skinless chicken breasts and salmon, low-fat dairy, and whole grains. Dr. Oz's Rule of 5s helps followers identify foods to avoid: if sugars, syrups, white flours, saturated fats, or trans fats are listed as one of the first five ingredients on a food label, you should stay away. Alcohol is permitted in moderation (one drink per day, preferably with dinner).
The diet may require an initial purge of your kitchen cabinets, and stocking up on recommended foods can be expensive. However, the cost should balance out with savings from cutting out fatty meats and prepared foods. Dr. Oz's Ultimate Diet provides tips on sticking to the diet and maintaining weight loss, and it emphasizes the importance of cooking your own meals.
In addition to his Ultimate Diet, Dr. Oz has also proposed a 21-Day Diet and a System 20 Diet. The 21-Day Diet recommends cutting out sugar, artificial sweeteners, and processed foods, and getting most of your calories from nutrient-dense vegetables and plant-based proteins. It allows for unlimited non-starchy vegetables and includes a list of 42 permitted veggies. The System 20 Diet focuses on intermittent fasting, suggesting that eating between 11 AM and 7 PM allows the body to burn off blood sugar and turn stored fat into ketones.

System 20
Dr. Oz's System 20 is a diet plan that focuses on intermittent fasting, allowing followers to enjoy cocktails and cheat days while losing weight and improving their overall health. The plan involves eating between 11 am and 7 pm daily, with meals consisting of a palm-sized serving of lean protein, half a cup of beans, and one cup of greens. The beans are a key component, as they nix cravings caused by extreme carb cutting and release powerful metabolism-boosting compounds.
In addition to the dietary guidelines, System 20 also recommends starting the day with coffee with a special "creamer" made from MCT oil, which boosts fat burn, kills appetite, and increases energy. This is followed by meals that include lean protein, non-starchy vegetables, and healthy fats, similar to the Mediterranean diet.
Overall, System 20 provides a comprehensive and science-based approach to weight loss and improving overall health, with followers reporting significant weight loss and improvements in mood, memory, energy, blood sugar, and blood pressure.

The diet recommends eating plant proteins, non-starchy vegetables, and healthy fats to promote weight loss.

The diet includes unlimited non-starchy vegetables for lunch, dinner, and snacks, with a list of 42 permitted veggies, including some root vegetables like beets and turnips.
Dr. Oz recommends eating half an avocado every day and a total of two tablespoons of olive oil at lunch and/or dinner. The plan limits fruit to two servings per day and suggests adding an ounce of nuts or a tablespoon of nut butter to one of the fruit servings as a snack. It also includes legumes, one serving of whole grains per day, and lean protein.
The System 21 plan eliminates sugar, artificial sweeteners, and processed foods. It recommends swapping morning coffee for two cups of oolong tea, which Dr. Oz claims will boost metabolism and increase mental alertness. The diet also includes a "cheat day" where you can eat whatever you like.
In addition to the diet, the System 21 plan also focuses on goal-setting, routine, and sleep. Dr. Oz recommends starting the day with a two-minute meditation and avoiding caffeine after 3 pm and electronics one hour before bedtime to ensure a good night's sleep.

21-Day Diet
Dr. Oz's 21-Day Diet is a weight-loss plan created by celebrity physician Dr. Mehmet Oz. The three-week diet is intended to jump-start weight loss, followed by a balanced, low-calorie diet for long-term weight management. The diet recommends eating plant proteins, non-starchy vegetables, and healthy fats to promote weight loss.
The 21-Day Diet eliminates several foods and food groups. Starchy vegetables like potatoes, sweet potatoes, carrots, and green beans are not on the permitted foods list. Sugar, artificial sweeteners, and processed foods should also be cut out. The diet suggests getting most of your calories from nutrient-dense vegetables and plant-based proteins. Dr. Oz recommends eating half an avocado every day and a total of two tablespoons of olive oil for lunch and/or dinner. Fruit is limited to two servings per day, and only one serving of whole grains is allowed.
The diet includes three meals and two snacks per day, along with lots of water and two daily cups of oolong tea, which Dr. Oz claims will boost metabolism and increase mental alertness. A serving of meat, poultry, fish, or eggs can replace a plant-based protein serving. Alcohol is permitted but limited to one drink per day, preferably taken towards the end of dinner.
Dr. Oz's diet also includes about 30 minutes of aerobic activity on most days, which is in line with the recommendations of the American Heart Association. However, it falls short in strength training, which the American Heart Association and the CDC recommend including at least twice a week. It is always advisable to consult a healthcare provider or registered dietitian before starting any new diet plan, especially if you have an underlying health condition.

Exercise and health goals
Dr. Oz's exercise and health goals are centred around the idea that individuals can take control of their health. His plans encompass many aspects of wellness, including diet, sleep, and exercise.
Dr. Oz recommends setting realistic and measurable goals for exercise and health. For example, he suggests that individuals should work up to 10,000 steps or about 5 miles per day. This should include half an hour of cardiovascular activity, such as walking, as well as strength training to build muscles once a week.
For those with an apple body type, Dr. Oz suggests metabolic disturbance training to slim the middle. This involves interval training with sudden bursts of high-intensity movement alternated with lower-intensity movement. Using an exercise stepper, individuals can begin by stepping up and down at a moderate pace for two to five minutes, before increasing the pace for 30 seconds to one minute, repeating this process throughout the workout.
Dr. Oz also emphasizes the importance of routine and sleep. He recommends starting the day with a two-minute meditation and establishing a consistent routine.
In terms of diet, Dr. Oz suggests intermittent fasting, where individuals eat only during an eight-hour window and fast for the remaining 16 hours of the day. During the eating window, two meals should be consumed, centred around beans, greens, and protein, with limited carbs and palm-sized protein portions. He also recommends healthy substitutions, such as frozen berries for dessert and clear alcohol with lime and seltzer for drinks.
Dr. Oz's weight loss plan also includes plant proteins, non-starchy vegetables, and healthy fats. He suggests using the Rule of 5s to determine what not to eat, avoiding foods with sugars, syrups, white flours, saturated fats, and trans fats listed as one of the first five ingredients.
It is important to note that Dr. Oz recommends consulting a doctor before starting any diet or exercise plan.
