Spread the love


Americans are constantly trying to lose weight each year. Whether it’s to lose weight because of their health or just to look and feel better, they may need to consider going through a change in lifestyle. Americans and others across the globe are spending billions of dollars each year on diets and other weight loss products each year.

This shouldn’t be a surprise to us considering that almost 30 percent of the world’s population is estimated to be obese. That amounts to around 2.1 billion people across the globe. If you are suffering from obesity or just someone who wants to maintain a fit and healthy figure, this is when you should consider going on a diet to help you lose weight. Many diet programs and plans claim to be one of the best ways to lose belly fat, or, perhaps advertise to be the best way to lose body fat, but I believe you should decide for yourself.

In this review, I will be discussing Brain Flatt’s, “The 3-Week Diet Plan,” and what it promises to anyone who undertakes his dieting program.

The 3-Week Diet Program is a step-by-step manual-based system created by Brain Flatt. Brian designed it to help consumers lose body weight, body fat as well as belly fat in twenty-one (21) days. The 3-Week Diet Plan promises to help you lose weight and It says it can help you lose up to 33 pounds in just 21 days.


Brian Flatt created the breakthrough weight loss program, ” The 3-Week Diet,” is a science-based approach to weight loss that

helps people melt away all unwanted body fat and belly fat in just 21 days.

Flatt has a degree in Biology and has been in the fitness industry for over 20 years. Flatt, 44 years old, started his fitness career as a professional trainer, weight loss coach, and nutritionist. He is well-known in Southern California and demand for his services soared, he opened his own personal training facility called R.E.V. Fitness, which he still runs today.

As a trainer and gym owner, Flatt was on the front lines in the “battle of the bulge.” He saw how his clients struggled to lose weight and keep it off and developed “The 3-Week Diet” as a way to help them achieve fast weight loss success.

“Flatt says, I’m a firm believer that with something that is hard to do like lose weight, enjoying quick success can provide just the encouragement that is needed for a person to commit long-term to the healthy changes they are making.”

Flatt created his diet program after seeing the frustration his clients were experiencing trying to lose weight. He reviewed over 500 medical studies, dozens of diet books and hundreds of diet systems, programs, gadgets, pills, and potions as he created the system. In all, he spent over a decade doing research and another two-and-a-half year fine-tuning his weight loss system.

“This is a revolutionary diet because it focuses on reducing cellular inflammation, which is the real cause of weight gain and is something that most diets ignore,” Flatt says. “Reduce cellular inflammation and you will boost your metabolism and increase your ability to lose weight.”

Flatt’s diet also corrects the bad information dieters receive and is simple to follow as it completely avoids the complexity of counting calories.

Flatt’s current mission is to help as many people as possible by spreading his diet system and tips around the world.

“I want to help people learn what to eat, when to eat and how to eat to lose weight,” Flatt says. “I also want to help them develop the mindset, or willpower, to lose weight and keep it off.

Since creating “The 3-Week Diet,” Flatt has also become an in-demand health and fitness speaker known for delivering a message of hope to those wanting to lose weight — a message that weight loss doesn’t have to be a slow, tortuous grind, that it is possible to lose weight quickly and easily.

What Comes In The 3-Week Diet Plan?

The 3-Week Diet Plan is a nutritious low-calorie diet consisting of four Phases. It is filled with fresh foods, and it recommends that carbohydrates should be kept from low to moderate. Brian as recommends for the diet to be successful, a person should walk every day before breakfast and if possible (but optional) to do weight training.

The 3-Week Diet Plan is a diet system with manuals focusing on certain aspects of weight loss. The program consists of four instruction-based manuals, including the:

-The Introduction Manual

-The Diet Meal Plan

-The Workout Manual

-Mindset and Motivation Manual

When Consumers purchase the entire system, which is also available as a digital download, they can start working on their weight loss immediately.

What Does the 3-Week Diet Contain?

One of the main focuses of the 3-Week diet is food, much as the name implies.

The diet portion of this program can be separated into four phases – detoxing phase, fasting phase, the fat phase, and custom dieting phase.

Of course, there are also plenty of rules for exercise. Altogether, the author claims that by strictly following all the rules outlined in this manual, the average person can lose between 12 to 23 pounds.

Detoxing phase – In this phase, the dieter is restricted to certain foods and contains a detailed explanation of what type of food users are supposed to eat. This phase lasts for seven days and it specializes in eliminating toxins and clearing waste from the body and helps detoxify the liver. It helps a person flush out their system as well as help them lose a considerable amount of body fat and belly fat along the way. It only allows certain foods that users can eat and are as follows:

  • Chicken
  • Broccoli
  • Eggs
  • Spinach
  • Tomatoes
  • Turkey
  • Cabbage
  • Beef
  • Cabbage
  • Kale
  • Mushrooms
  • Nuts

This part is quite restrictive in terms of the food that a person can actually be allowed to eat. As long as a person sticks with this phase, he/she will be able to lose weight.

Fasting phase – The fasting phase makes the users do ‘The 24 Hour Fast,’ in which you are supposed to skip meals for one day.


Flatt created the fasting phase of his diet plan so that it is easier for most people to achieve. The fasting phase allows a person to start the fast at the end of one day, carrying it through the night as a person sleeps, and on until the end of the next day. This is so that a person’s time is spent sleeping which makes it less stressful.

Fat Phase – This phase lasts for two days and users are supposed to eat food with more calories and which may contain more than 70% fat. Flatt speaks about how fat isn’t actually related to “getting fat.” He explains how to add healthy fats in your diet, you are able to burn more fat. Flatt advises adding healthy fats to a person’s diet to ensure that around 80 percent of the total calories consumed is derived from healthy fats. Dieters should not consume more than a certain number of calories, typically 1200 calories a day.

Then, it is all about tailored dieting.

Custom Dieting Phase – During this phase, a person has to calculate his/her individual basal metabolic rate (BMR) which tells him/her how much energy they use up when at rest. This helps to determine just how many calories each dieter should consume each day to lose weight. This phase will continue until the 21 days are up.

In this phase, Flatt suggests that a person on The 3-Week Diet should start consuming supplements to make up for the restriction with certain foods. So, those who wish to be strict about their participation will need to purchase these.

Importance of Supplements by 3-Week Diet Plan

Supplements help provide a person’s daily energy and fish oil are necessary for your weight loss journey, too. They are not only


perfect for losing weight, but also for keeping your mind and body healthy. Keeping your mind and body healthy is crucial in having a wealthy and satisfying life.

You should give more priority to it over the others because if you don’t, everything else will just be a waste of money, time, and effort.

Fish oils help in burning calories, lowering blood pressure, reducing inflammation, reducing the chance of a sudden heart attack of people who are suffering from heart disease, removing pain in joints, supporting eye health, treating ulcers, and a lot more.

-Vitamins A, C, and D are recommended to be added while on this diet.

The 3-Week Diet claims that the user will be able to accomplish the following in twenty-one days, as compared to what other diet plan programs do in two to three months

  • Lose 12-23 pounds of pure body fat
  • Lose 2-4 inches from the waistline
  • Drop 2-3 dress sizes
  • Increased muscle tone
  • Decreased cellulite
  • Improve metabolism
  • Get healthy skin and hair
  • Improve your cholesterol levels

The 3-Week Diet, And Exercise Program, Too

Although The 3-Week Diet is a diet, it has gives instructions on exercise as well. Exercise in this program start off slow and are easy enough for individuals who are “out of shape” to accomplish. Exercise help to complement the weight loss that is a result of the dieting and the workouts are only twenty minutes long. They are quick enough to fit into anyone’s schedule and need to be repeated at least about three to four days a week.

It should also be noted that the diet and exercise plans are more targeted towards healthy individuals who follow traditional eating plans. Individuals with pre-diagnosed medical conditions such as diabetes should not partake. Also, due to the methodology used, this isn’t a great plan for vegans or vegetarians.

This program has been created in such a way so that it is specific to each individual’s needs, making it beneficial to everyone that reads and uses it.

The 3-Week Diet is very rigid in detail and there is very little room for cheating or cutting corners. However, should customers stick with all the instructions provided in the book, they will undoubtedly see great results.

Pros and Cons


Firstly, the main advantage of The 3-Week Diet Plan by Brian Flatt is it works! When a person follows the plan that has been laid out for them, he/she will undoubtedly begin to lose weight. At the end of the three weeks (21 days), he/she will have definitely lost a considerable number of pounds.

Secondly, this program contains a healthy balance of both diet and exercise. In addition to losing weight, people actually begin improving their physical condition and if he/she decides too, can change their lifestyle to one of being healthy. This is partially what makes the final results so astonishing – people aren’t just lighter, they also look more toned.

Thirdly, the program teaches people how to keep a journal so they can keep track of their food intake and it also helps them keep track of their progress. All this information make the overall plan a lot more achievable and successful.

And finally, the program has a money-back guarantee. So, if dieters aren’t pleased with the transformation they have seen, they can get their money back as compensation.


Despite being successful, the diet is quite restrictive. This means that people who follow it must have a lot of self-control if they are to succeed. The limited foods can also become a little tiresome after a time.

By reducing calorie intake, a person can have low energy levels and the program is very restrictive when it comes to carbs and calories.

The program recommends using supplements. This can be discouraging to some if they don’t want to spend the money. Also, there are many who see supplements as being unhealthy.

While you will definitely lose weight on this plan, there is no real guarantee about how much weight you will lose. The actual amount varies from person to person and depends on numerous factors, including what type of body he/she has or how strictly a person follows the diet.

What Will You Learn from 3-Week Diet?

The 3-Week Diet will teach a person how to diet correctly especially if it is his/her first time. With the help of the 3-Week Diet Plan program, a person will be able to know how the system works a lot easier since it was divided into different parts such as detoxing, fasting, the diet, and the proper mindset and motivation, supplements as well as an exercise program.

It teaches a person the right kinds of food to eat on a daily basis which will help on his/her weight-loss journey. This helps because no matter how much effort a person puts into exercising if the person does not eat healthy food, his/her efforts will be in vain.

What Do You Need To Avoid?

While on The 3-Week Diet, it does not recommend using fat burners because some may be harmful to your body. However, they can be effective, with combined diet and exercise, but they do not provide the results that you may need. If you want to try
it, try it at your own risk. It is still best to follow the natural way of losing weight by dieting and working out.

What People Are Saying Using The 3-Week Diet

“Love it! Totally doable diet! Here goes losing at least 10 pounds and feeling better after I eat! So excited.” says Libby.

Beverly D. said, “I don’t lose as fast as I want to. However, I have lost a lot of weight.”

In Conclusion

Having a successful weight loss journey is not just about eating right, but it also involves doing the right type of exercise while maintaining the right mindset. And this is exactly what Brian Flatt’s, “The 3-Week Diet” does. It involves detoxifying a person’s body while fasting, eating the right foods, and developing the right mindset to accomplish a person’s weight loss goals.

The 3-Week Diet program is not a miracle cure to end all problems with weight gain, but it is a tedious plan to help a person lose weight, body fat, and belly fat. It is quite restrictive and people who follow it must have a lot of self-control if they are to succeed. The limited foods can also become a little tiresome after a time.

This program was not designed just to show a person theoretically how he/she can lose 10 to 20 pounds in just 3 weeks, but it was designed to show him/her how to actually make it happen.

We see a lot of fitness programs on the market these days that only combine workouts and diet, but Brian Flatt has taken The 3-Week Diet program” to the next level by including the “Mindset & Motivational Manual.” He included this mindset manual into the package so it would ensure people stick to his program.

In my opinion and from my experience with trying to lose weight, you have to have the right mindset in order to reach your weight loss goals. This a big advantage that the 3-Week Diet has compared to many other diet programs online these days.

I love this dieting program and for my money, it is a real winner!

And not only that, but it comes with a 60-day money back guarantee and it can be purchased now for only $47.

  1. I think your website is awesome. There is a lot of rich information that I didn’t know about and I found it well informed. I would actually purchase the program but, I am breastfeeding and I cant restrict my caloric intake in any way for the sake of my milk production.

  2. Hi! I use to read and know a lot of articles about dieting but this one seems different. The Three week diet plan includes all the info you might think of, mindset included. As someone says, if I cite correctly “all creatures have a diet, only man is on a diet”, that’s because most people don’t feed but indulge themselves.
    Keep on writing this stuff! It is very useful.

  6. I like that detox is included in the 3 week diet plan. Getting the bad things out of your liver will help quite a bit when you are trying to loose weight.
    Diet and exercise always go together. Can you repeat the program after the first 21 days to keep loosing a lot of weight.
    Are there any upsales with this program, or just the one time $47.

    1. Yes, as a matter of fact, you can repeat the process after the 21 day period. There is a section in there for that and yes there are 2 or 3 upsells to the program but that’s entirely up to the individual if they want to purchase them.

  7. Great article!
