The Mayo Diet is gaining some popularity, and I wanted to dedicate some time to understand its effectiveness in weight reduction.  Is the mayo diet a fact, fad, or myth?

Well, let’s see what Wikipedia says about the mayo diet:

The Mayo Clinic Diet is sometimes used as a name for a diet plan based mainly on eggs, meat and grapefruit. Claims for it include that it is used on cardiac wards for patients needing to lose weight quickly, and that the grapefruit acts as catalyst to burn fat. However this diet is high in cholesterol and saturated fat. The British Heart Foundation and American Heart Association (among others) warn that these can cause heart problems.

The Mayo Clinic refers to it as a myth and advises people not to follow it.

Being that the Mayo Clinic is a non-profit medical practice, I tend to believe their opinion of the mayo diet…

It’s not only a myth, but the mayo diet may be a dangerous fad, in my opinion.

I’m sure this will continue to cause confusion because numerous versions of the mythical mayo diet have been in circulation for decades.  The Mayo Clinic finally made the official mayo diet available in December 2005.

For comparison, here’s the UNOFFICIAL mayo diet:

Breakfast
1/2 Grapefruit or 4 oz. Grapefruit Juice (unsweetened)
2 Eggs (any style)
2 Slices Bacon

Lunch
1/2 Grapefruit or 4 oz. Grapefruit Juice (unsweetened)
Meat (any style, any amount)
Salad (any kind of dressing)

Dinner
1/2 Grapefruit or 4 oz. Grapefruit Juice (unsweetened)
Meat (any style, any amount) (fish may be substituted for meat)
Vegetables (any green, yellow, or red vegetables cooked in butter or any seasoning)

Bed Time Snack

1 glass tomato juice or 1 glass Skim milk

Vegetables Allowed
Red onions, green onions, bell peppers, radishes, cucumbers, broccoli, spinach, lettuce, cabbage, carrots, peas.

Vegetables to Avoid
White onions, potatoes, celery.

Instructions

  1. At any meal you may eat until you are full - until you can’t eat any more.
  2. 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.
  3. The grapefruit is important because it acts as a catalyst that starts the burning process.
  4. Cut down on caffeine - it affects the insulin balance that hinders the burning process. Try to limit to 1 cup per meal at mealtime.
  5. Don’t eat between meals. If you eat the combination of food suggested you will not be hungry.
  6. 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.
  7. 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.

Here’s an example of an OFFICIAL mayo diet meal:

**Pancakes with syrup and strawberries

**Dilled Pasta Salad with Spring Vegetables

**Rosemary Lemon Chicken

**Fresh Apricots

 

With the official Mayo Clinic plan you can pretty much consume large amounts of vegetables and fruit, plus whole-grain foods, lean protein and heart-healthy fats. The objective is to limit your intake to foods that are lower in calories, which allows you to eat larger amounts of food.  Basically, if it’s lower in fat content, then more food can be eaten due to the fewer calories contained in protein and carbohydrates.  Recommended foods are fruits, vegetables, legumes, poultry, fish, whole grains, low-fat dairy and unsaturated fats.  This is not a restrictive diet plan, so there’s more willingness to stick with this type of diet for the long term.

Well, there you have it…

The mayo diet exists.  You just need to be careful in following the correct diet plan.

Dear All, Some viewers of InvestServ’s Fit365 “What is Nutrition” video have asked me whether pink salt is better than table salt. I thought in this video I would talk about how you can decide if this is true.

How to Figure Out If A Health Claim is True:
You can go onto the website, www.pubmed.gov, which is a search engine from the National Library of Medicine and National Institute of Health. This search engine has an index of all the papers from 4,800 journals written in over 70 countries: if pubmed doesn’t have a paper on your question of interest, then you can be sure that no good research has been done on it.

Fit365’s health claim that pink salt is healthier than sea salt is currently not backed up by any scientific literature. I have read previously that there are toxins in processed table salt–but the literature had no sources. I have not found any evidence that pink salt does not have the same toxins either — please let me know if you have this information and I will be happy to post up a new video revisiting these comments.

For more on this subject, please refer to:
Mayo Clinic health letter [0741-6245] yr:2006 vol:24 iss:12 pg:8

For Salt Intake Guidelines, in general, a daily intake of no more than 4 to 6 grams of salt (2400mg of sodium) is recommended

General idea behind these health videos:
I’m a first year medical student here at the U.S.. Every day, I’m learning exciting and critical topics on medicine and health. But too often, the things I’m learning about never reach the public.

I wanted to try an experiment — sharing health information on youtube, with the sole purpose of trying to get more important health information to you all. Unlike some of the other health videos out there, mine are not about promoting a book, a diet, a pill, an agenda. I hope to answer your questions either through e-mail or through the video updates — please, please, (please!) e-mail me any questions and I will try my best to answer them by asking my professors and by citing credibles sources (JAMA, New England Journal of Medicine, etc…)

e-mail:
unitedstatesmedicalstudent@gmail.com

I hope this experiment works — and if it fails, I hope someone sees these videos, says, “hmmm, these are bad videos, but I love the idea,” and decides to go for it.

P.S. I wanted to point out something important: I’m just a medical student, so my posts are hopefully conversation starters, but only conversation starters — not medical advice. If my posts intrigue you, please read more about the topic and discuss about it with your doctor. I’d be happy to send you the information in the journal articles I talk about. Also, the opinions expressed in this post are not necessarily those of Harvard Medical School, its affiliated institutions, or Harvard University. Best wishes!

Dear All, Hopefully, I’ll add more specific nutrition tidbits that I learn throughout the year, but I wanted to start by posting these websites below. Unlike some of the other nutrition sites out there, (as far as I know) these ones aren’t selling diets or health food products. They also try to examine the actual research, data and evidence on the topics.

As with anything, please be careful about what “evidence” exactly is: it’s easy for someone to take a couple of sentences from a research study, exaggerate the claims, and misrrepresent. Also, always be on the watch out for conflicts of interest — for example, the Mayo Clinic has a bookstore that’s selling their books. Unfortunately, conflicts of interest happen everywhere — I tried to do the best I could by selecting sources from well-respected institutions. But please use your critical judgment when reading.

Reference Websites on Nutrition, Diets, Vitamins & Herbs:

1) Nutrition information (including diet, food and vitamins) from the Harvard School of Public Health

2) Direct Link to Vitamin information from Harvard School of Public Health

3) Supplement and Drug Index from the Mayo Clinic (Has information on supplements such as herbs)

5) National Institutes of Health Website on Complementary and Alternative Medicine

6) Linus Pauling Institute Micronutrient Information Center (has information on vitamins, minerals and other nutrients):
