Mayo Clinic Diet

The diet plan often referred to as The Mayo Clinic Diet is actually not recommended, sponsored by, or approved by the actual Mayo Clinic in any way.

Types of food allowed:

Grapefruit, Meat (Red, Chicken, Turkey, Pork, Sausage... basically, Any Meat), eggs, seafood, nuts, butter, cheese, some (low starch) vegetables, artificial sweeteners, diet soda, water. No complex carbohydrates are included on this diet.


People who like to eat grapefruit, meats, and fatty foods may enjoy them in unlimited amounts. Weight comes off fast at first. The diet incorporates a 3 day break and return to normal food every 14 days to prevent the thyroid gland from entering the body in a state of starvation.


This is a high fat diet. This diet limits carbohydrates and teaches people to choose calorie dense food. This diet is likely to lead to weight gain and heart disease once the diet is over.

Health Issues:

This diet limits many healthy vegetables and necessary carbohydrates. Diets that are high in fat raise blood cholesterol levels and increase the risk of heart disease. This diet is not in any way associated with the Mayo clinic.

1. At any meal you may eat until you are full - until you can't eat any more.
Don't eliminate anything from the diet, especially don't skip bacon at breakfast or omit salads. It is the combination of foods that burn fat.

2. The grapefruit is important because it acts as a catalyst that starts the burning process.
Cut down on caffeine - it affects the insulin balance that hinders the burning process. Try to limit to 1 cup per meal at mealtime.

3. Don't eat between meals. If you eat the combination of food suggested you will not be hungry.
Note that the diet completely eliminates sugar and starches, which are lipids and form fat. Fat doesn't form fat; it helps burn it. You can fry food in butter and use butter generously on vegetables.

4. Do not eat desserts, bread, and white vegetables or sweet potatoes. You may double or triple helpings of meat, salad, or vegetables. Eat until you are stuffed. The more you eat of the proper combination of food, the more you lose.

NOTE: While the nutritional value of this diet has been widely debated, and there is no evidence to support grapefruit actually "burning" calories, it is documented that breaking a diet 2 out of every 14 days can help prevent the body from going into a state of percieved starvation that dramatically slows weightloss after the first two weeks in many diets.
