5 Factor Diet Ingredients and Side Effects

The information on the 5 Factor Diet is difficult to find, as the official website redirects to an Amazon.com page to purchase it. Very little information about it is offered from the actual official website.

Most of what’s known about this diet has been shared by users and other sites. It’s revealed that the 5 factors of the diet are to prepare 5 meals a day which take 5 minutes each. A 25 minute workout broken into 5 stages is suggested 5 times a week

The basics of every meal are that it must contain:

Complex carbohydrates. This includes things like oatmeal, quinoa, wild rice, beans, vegetables, sweet potatoes and brown rice.

• High fiber.Wild rice, flourless wheat bread, whole grain cereal, beans, fruits and vegetables with the skin on.

• Healthy fat. Peanut oil, olive oil, canola oil, flaxseed, sunflower oil and fatty fish. The kinds of fish allowed are halibut, salmon and others.

• Fluids that are sugar free such as coffee, tea, unsweetened energy drinks, and sugar-free soda.

• Quality sources of protein. Egg whites, fat-free dairy, and lean meats.

There’s also cheat days allowed where people can indulge in the foods one likes for one day of the week. It also heavily relies on using foods low on the glycemic index, which is a scale of foods which are ranked in terms of their effects on how high they raise blood sugar. This low glycemic approach is used to help provide long lasting energy and improved mood through the day. This scale has been shown to be effective for regulating blood sugar.

A sample of the types of foods one can eats includes:

         • Breakfast: A special 5 Factor French toast.

         • Morning Snack: Non-fat cottage cheese with a pear.

         • Lunch: Brown rice and navy beans.

• Afternoon Snack: Non-fat French onion sour cream with added celery.

         • Dinner: Halibut with 5 different spices.

Many low fat options will often be suggested as well.A comprehensive list of the top 10 ranked diet plans is featured in the link here.

According to a review by a Dr. Melinda Ratini:

“scientific research on the 5-Factor Diet is lacking”

“Research is mixed concerning the weight loss advantage of eating smaller meals more often”

“amount of weight that you can lose, however, depends on many things, including your size, gender, and activity level”

In considering all this, it’s clear that there is still a lack of evidence provided to show this is effective and long lasting.

There is no clear evidence that separating meals into 5 different meals a day is any more effective for appetite suppression than any other amounts.

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

5 Factor Diet Quality of Ingredients

The kinds of foods eaten are low glycemic, rich in protein, full of fiber, and not processed. This is a healthy approach to weight loss, though it’s unknown if this is better than any other general weight loss advice. The website Love To Know adds:

“it is not for everyone. For people with diabetes, the amount of carbs provided… may not be enough”

The foods offered are quality, but it’s clear that there is no proof to back up the claims that this is better than other diet plans. Without knowing how this was created and why the specific choices were made, it’s impossible to determine if there’s any legitimate science to help back it up.The list of the highest rated top 10 diet plans is featured in the link here.

The Price and Quality of 5 Factor Diet

Pricing depends on where one purchases their groceries. The overall quality of the foods does seem healthy as lower calorie options are offered, but much more information is needed to make an informed decision on the 5 Factor Diet.

Web MD also adds:

“This may not be a good choice for those who have to travel a lot for work, have an inflexible schedule, or prefer to eat out, as food prep and timing may be a problem”

The concern about this diet is that there are restrictions placed and no alternatives. Very specific food choices are suggested, and it can take time to prep all of what’s needed.  This is why some users say it was too time consuming. For a comprehensive top 10 ranked diet plan list, follow the link here.

Customers did say that it was pricy to have to buy all the recommended foods, and that the recipes were difficult to create. A few recipes were listed online which had users adding large amounts of certain foods which don’t mix well with others.

One customer posted a recipe that asked for 20 asparagus spears with 2 cups of shredded carrots, which according to them, was impossible to mix well. Many others had issues with the overall quality of the recipes provided. For some the kinds of foods required were too complicated to create, and there were issues since the foods one has to eat repeatedly can become costly.

Business of 5 Factor Diet

The creator of 5 Factor Diet is the celebrity trainer and author Harley Pasternak. He does have an official website for the diet, but there is very little information provided. No evidence is offered to help show how why this diet would actually work. The only sort of support is a few celebrity testimonials.

It’s unclear why the specific foods offered in the recipes section were selected. The science behind eating more meals thought the day has not been proven as an effective weight loss strategy either.

Much more information is needed to help show why this would be effective, safe, and better than other diets. The link provided here has a list of the top 10 diets for weight loss.

Customer Opinions of 5 Factor Diet

Here are direct quotes taken from user reviews:

“recipes are definitely not for the working person unless you have a personal chef”

“diet is not sensible if you’re on a budget”

“information in this book was too basic”

“very basic and really common sense at this point if you know anything about nutrition”

Many mentioned how the recommended foods were far too limited, and that it would be nearly impossible to uphold the diet without feeling bored. There was also concern that the amount of meal prepping would take too much time, and the reason why celebrities have endorsed it is because they can hire personal chefs.

There was also disappointment with the quality of information presented. Some called it common sense weight loss advice, and that they learned nothing new from this diet. This was often mentioned by people who said they were disappointed to read the book.

Since the foods suggested are very specific, the options offered were deemed as being either expensive or unsatisfying to eat.  For a comprehensive list of the highest ranked diet plans click the link here.

Conclusion - Does 5 Factor Diet  Work?

In reviewing the 5 Factor Diet it became clear that its approach is to provide support for sustained appetitesuppression, quality macronutrients, and exercise recommendations. There is no evidence that this is a safe and effective weight loss approach. Some users have said that prepping the recipes can be time consuming, and that there is very little variety. There was also concern over the lack of substitutions one could make. The advice offered seems very general, and many have said thatthey didn’t learn anything from reading the official book.

Of all the diets available, our experts have concluded that the most effective for well-rounded weight loss is the 18Shake Diet. This diet provides an all-natural meal replacement and diet pill made to help burn fat and suppress appetite for hours. Many users say that the meal replacement has a great taste, is easy to blend, and can alleviate hunger. The benefits listed of the diet pill are fat burning with no added stimulants of artificial additives.

The 18Shake Diet is also supported by a full 30 day money back return policy. This risk free return is offered with no questions asked. More information on the 18Shake Diet can be seen when you click the link here.

The book is very easy to follow, so there's no need to follow an online version. Recipes are great if you're a time-starved single person, as they are FAST and only make a couple servings. Problem is, if you're a foodie, these recipes are BLAND, BLAND, BLAND. They all need some serious extra spices. All in all though, good jumping off point for healthy meal ideas if you already know well the fundamentals of weight loss.

hi wot does the food tast like

This has been a great experience so far. I have had great results and it has been fairly easy to adjust. I needed to make a lifestyle change and it teaches you to eat healthy. Initially the cheat day was great and I looked forward to it. Now I find myself wanting to eat healthier on that day as well. There has been one very noticable change that is embarrasing- gas. I have bad gas all the time and don't know what to do about it. I assume it is all the fiber, but would like to know what I can do.

That Diet is so logical, its increasing your metabolism and make you lose pounds like you will never believe. I gained weight... but I lost 8% of fat... the gain was muscles... The hormones stabilizing after 15 days


Be sure this diet looks right for you. If you cancel, even within the 3 days normally allowed by law, they will keep a portion of the charge.


this be the phatest diet i ever be on i be lookin good for the brothas


I got a newsletter from 5 factor-----Had one of the worst suggestions I've ever heard. It was saying to microwave most of your food that you cook. I am a doctor and know that microwaved food is terrible. People should avoid using their microwave as often as they can.


I have done this 5 factor diet for the past 4 weeks and so far the results are great. i have lost 12 lbs.


With Atkins you can lose a pound a day...but you have to be willing to do it for the rest of your life


If it is only meant to last for 5-weeks, why is the online plan for 13?


The diet for the stars! Anyone try the 5 factor diet?
