Top Rated Diets of 2024
What is it?

The UltraSimple Dietis a weight loss diet claiming to help people lost ten pounds in seven days. You have to avoid eating what’s considered allergenic foods, and then slowly reintroducing these kinds of foods to see which should be avoided in the future.

The main idea is to see which foods cause inflammation and weight gain by resetting your diet. It’s meant to be customizable and catered to one’s own needs. The kinds of foods allowed are based off of what’s less likely to cause any unwanted allergies. Our experts rate many different diets and they’ve found the most effective for weight loss is the 18Shake Diet. It offers an all-natural meal replacement that suppresses appetite for hours, and a fat burning diet pill. You can learn more about the benefits of the 18Shake Diet by clicking the link here.

The UltraSimple Diet Ingredients and Side Effects

The allowed foods one can eat are a combination of:

• Salmon, cod, sardines, cod, organic chicken breast, and olive oil.

• Berries vegetable broth, fresh vegetables, almonds, walnuts, lentils, brown rice, and macadamia nuts.

Foods which are temporarily banned are:

         • Pork, beef, lamb, tuna, and shellfish.

• Yeast, eggs dairy, gluten foods, corn, potatoes, eggplant, bell peppers, tomatoes, peanuts and dry fruits.

• Coffee, corn syrup, table sugar, processed junk foods, hydrogenated fats, and foods with colors and additives.

• Stimulants, nightshade foods, flour, and processed goods.

The diet allows the following same foods every day as a meal:

• Breakfast: Green tea, lemon juice, UltraBroth and Ultrashake every mid-morning.

• Lunch: ½ cup of brown rice, ½ cup of fruit or berries, two cups of steamed vegetables, and an UltraShake. As an afternoon snake UltraBroth and UltraShake are advised.

• Dinner: Two cups of steamed or sautéedvegetables ½ cup of brown rice and UltraBroth, and four to six ounces of lean fish, chicken, or legumes with spices or tofu.

If a bowel movement is not had every day by 10am the diet claims this is a sign of constipation. To relieve this it’s advised to take ground flaxseed and 2 to 4 capsules of magnesium citrate twice a day. If this also does not produce a bowel movement, it’s advised to take an herbal laxative before bedtime, or either a fleet enema or magnesium citrate liquid.

This means that the kinds of foods one is limited to can potentially not be enough for regularity.

A 20 minute UltraBath is recommended to improve health and to detox and relax the body. There’s also an emphasis on eating organic foods and cooking one’s own meals at home. For a list of the highest rated diet plans, click the link here.

Customers have mentioned that they substituted both the broth and shake with their own mixture in order to save money.

EDITOR’S TIP: Combine this diet with a proven meal replacement such as 18 Shake for better results.

The UltraSimple Diet Quality of Ingredients

Most of the foods one will be eating are organic and free of any artificial or processed ingredients. While this is a healthy way to eat, there are very few foods allowed. Several foods are banned while on this diet. This is in order to truly figure out what foods might be causing allergic responses.

While there are some foods which can cause allergies, this is not the case for most people. The Food Allergens group mentions:

“clinically proven allergy to any foodoccurs in 1-5% of the total population”

This typically affects children more than adults and the Center for Disease Control and Prevention adds:

“90% of allergic reactions in affected induvial: mil, eggs, peanuts, tree nuts, fish, shellfish, soy and wheat”

Our experts have rated and ranked several of the best weight loss diets in a list found here.

Therefore these foods are the main reason for one to have allergies, while TheUltraSimple Diet bans several others. When one has a food allergy this will likely result in a strange sensation of the tongue, hives, and other symptoms. This can even lead to death; however, this is often already discovered by people.

This diet claims that by banning several foods that this will removetoxins, which is not a proven fact. Allergies are serious and typically display symptoms. There’s no evidence that this includes weight gain however. Certain foods might increase inflammation and cause sickness, but there are better ways to determine if this is the case. Actual medical tests can be taken to help people find out if they have any potential food allergies.

The official book also states that there are certain symptoms one might face during the detoxing phase:

         • Hunger, fatigue, and bad breath.

         • Nausea, constipation, and ill feelings

This is claimed to be due to the toxins which are being flushed out of the system. There is no evidence that this is true however, as the bodies internal organs already help to flush out any potential toxins. It’s more likely that the potential symptoms are due to either malnourishment or a severe loss of calories which can lead to hunger.

The Price and Quality of The UltraSimple Diet

The book itself can be purchased on Amazon.com for $7.19. There are also suggestions for products under the UltraSimple name such as a broth, bath product, and shake.  Most of what one will eat will be made up of organic foods, which can be incredibly pricy.

It’s difficult to determine the overall cost, as what one pays will depend on what grocery store is used. However, as you’ll see in the“Customer Opinions of the UltraSimple Diet”, this diet is costly to maintain according to many users.

There are also issues with the severe limitation on foods. This can make it difficult to sustain this diet. One has to make significant changes to diet and this can also make eating out impossible.

A list of the best weight loss diets are compiled in an easy to read list found here.

Business of The UltraSimple Diet

The UltraSimple Diet was created by a Dr. Mark Hyman who specializes in family medicine. He is not trained in nutrition and has no background in weight loss. His official website also does not mention this diet; instead he discusses 3 other solutions for weight loss and overall health.

The diet claims that toxins are a leading cause of failed weight loss. There is no scientific proof provided to help prove this claim.

EDITOR’S TIP: The top 10 list of the best diets is available here.

Customer Opinions of The UltraSimple Diet

Featured here are some quotes from customer reviews:

“I was hungry the entire time and I got really sick of the food”

“I tried this diet and today ended up in a walk-in clinic with a severe gallbladder attack”

impossible of the average working American”

“you would need a large, expensive, grocery list and a week off to do everything it instructs”

Some people did enjoy the diet since it restricts many foods which are known to increase weight gain. Since the majority of the diet restricts many fattening foods, and what are allowed are mostly low calorie foods, this makes it easier for one to lose weight.

Some experience many side effects and health problems while on this diet. Many described it as being far too restrictive and difficult to uphold as you can’t eat many foods. There were also complaints about the price. Users have repeated the idea that it’s incredibly expensive to eat the advised organic foods.

Conclusion - Does The UltraSimple Diet Work?

There are many foods which are not allowed while on this diet which are claimed to be potentially toxic as they are allergy causing. While this includes things like processed foods and sugars, there are also healthy foods which are not allowed.

The diet also emphasizes eating a largely organic diet with very few food options to start with. While this can potentially help with weight loss, there is no scientific proof that the banned foods are toxic to the body. Most of the population does not suffer from food allergies, and those that do typically experience serious symptoms to help warn them. There is no evidence provided by the creator nor does he have a background in nutrition. Many users have also experienced side effects and a lack of weight loss benefits.

Our experts review many different diets and the overall most effective for weight loss was found to be the 18Shake Diet. It combines an appetite suppressing meal replacement alongside a fat burning diet pill. They have a combined effect of promoting improved weight loss results without the use of preservatives, colors, artificial ingredients, stimulants, or fillers. Users have left glowing reviews on their official website expressing how effective it is for weight loss.

The 18Shake Diet is also backed by a full 30 day money back guarantee. This risk free return is offered with no questions asked. Learn more information about the 18Shake Diet by clicking the link here.

It is impossible to take a review seriously that includes these kinds of typos:
“90% of allergic reactions in affected induvial: mil, eggs, peanuts, tree nuts, fish, shellfish, soy and wheat”
An affected what? And what is "mil"?

Great kickstart for me, sluggish metabolism, early stages fatty liver disease, 20kgs over weight. I work part time and am a full time carer for my husband so a simple step by step guide has been perfect.

I bought the books, read with relish, then questioned an apparent hypocrisy which was answered with a form letter. I questioned the form letter, then was met wit silence. Hyman's advice to use no processed foods, with nothing in the name we don't recognize, and which would be known to our grandmothers, is sound. Then he advocates taking all manner of unproved supplements which are: 1. Processed. 2. Contain unfamiliar elements, and 3. Would be laughed at by our grandmothers as snake oil. And snake oil, in any form, remains firmly the province of conmen.

This review is seriously flawed.
"Pro:Seven day time commitment is not too long."
"Con: Program can last for up to three months"
LOL! This is not some week long or 3 month long 'diet'!

It is a regimen upon which you start and CONTINUE! It is a lifestyle change, not dome lose weight quick temporary self-deprivation program as imagined by the fool reviewers!

Ironically, as this site focuses on diets as some short term fix it quick routine rather than an ongoing healthy lifestyle approach to eating that we treat the common sense whole plant food, low sugar & fat, sans meat dairy and eggs approach of Hyman (& Esselstyn, McDougall, etc.) as some fad to be done for a week!

Sure the weight loss is temporary, IF you return to the typical American diet high in processed crap, salt, sugar and fat!

Bottom line, the review totally misses the point. this is not some lose weight fast so you can return to eating what you did before that caused the problem - rather it is a basic lifestyle change.

I like this diet, but modify it to fit an everyday healthy lifestyle. I add the night shade vegetables and alcohol everyonce and a while. Other than that, I pretty much stick to it and can keep it up for months at a time. It is definitely harder than other diets because of the food prep work...but worth it!

I do this diet 4 times a year. I am a personal trainer and weight loss consultant and always recommend it to my clients. I am a really healthy eater to begin with, and I still lose anywhere from 4-7 lbs. the week that I do it. It's a great tool to fall back on after the holidays, a vacation, or just when life is stressful. I LOVE this plan!

posted Mar 15th, 2010 6:55 pm



It is hard to get started because there is a lot of prep work. It also takes longer to fix the food. It was good and I lost 12 lbs. in the two weeks. First week to cut out junk stuff and second week of the diet. I feel much better and my blood sugar is as low as it has been in the last year. I'm on the way to health....finally

BACKGROUNDBACKGROUND Start the Diet Now Advertisement

The UltraSimple Diet: Kick-Start Your Metabolism and Safely Lose Up to 10 Pounds in 7 Days is a book written by Dr. Mark Hyman. Mark Hyman is a medical doctor who is also the editor in chief of Alternative Therapies in Health and Medicine.

The UltraSimple Diet offers a fast plan that will have you on your way to weight loss the quick and easy way. You can even lose up to 10 pounds in the first week. Some of the things contained within The UltraSimple Diet are a seven-day weight loss plan, detailed instructions on what to do each day, which foods to eat, which foods to avoid, exercises to do for those that are busy and how to keep the weight off for good.

The UltraSimple Diet has been medically tested over many years to be effective. The two central issues behind weight gain covered by The UltraSimple Diet are toxicity and inflammation. Although the book is called The UltraSimple Diet, it is more formulated to help you deal with toxicity and inflammation rather than solely losing weight. The program helps you deal with certain chronic illnesses and lets you experience the rewards that come from eating a clean diet.

Dr. Hyman is also the author of UltraMetabolism.
