3 Week Diet Review || 3 Week Diet System

NOTE: This review is an assessment of the product called “3 Week Diet,” which is authored by Brian Flatt. It should not be confused with the product created by Josh Bezoni and Joel Marion which carries the exact same name.


  • This weight loss program would entice you if you want to lose weight quickly, like “12 to 23 pounds in 3 weeks” quick. However, being able to deliver that promise is a whole different story.
  • Has separate sections for each of the weight loss trifecta component – dieting, exercising, and motivation.
  • The presentation is clean and the design is aesthetically pleasing.
  • That’s about it.


  • Even with further research, we were unable to verify the author’s identity and credentials as a health and fitness expert. The amount of available and researchable material just doesn’t match what you would expect from someone with such supposed achievement claims.
  • In several instances, the author makes controversial statements about weight loss and simply expects the readers to take his word for it. For example, he states that the primary reason that other diets fail is because they do not produce results fast enough but he doesn’t provide any statistical support.
  • There’s a disturbing lack of medical and scientific support included in the program, especially regarding the safety of the methods and losing that amount of weight so quickly.
  • This program lacks proof of real life results. Even testimonials from medical professionals or before and after photos of real individuals who have used this weight loss program would make the basic principle of the product ever so slightly more convincing.
  • Strongly recommends the additional purchase of supplements in order to achieve ultra-fast and effective fat loss.
  • There’s not much substantial material along the different sections. This program may cover every aspect of weight loss, but it covers them shallowly.
  • Customer support appears to be either extremely inefficient or non-existent. We sent out an inquiry and never received a reply.


3 Week Diet Key Product Details


3 Week Diet is a program that covers the weight loss trifecta of dieting, exercise, and motivation and is intended to produce extremely quick fat loss results, guaranteeing to shed off 12 to 23 pounds in only 21 days. Expect this program to change your eating habits, teach you to follow a strict eating program that restricts carbohydrates while utilizing strategic protein consumption, go on an exercise habit, and keep a close eye on your progress.

The man behind this weight loss plan is Brian Flatt. According to his website, he’s a sports nutritionist, a health coach, and a personal trainer who has been in the fitness industry since the 90s while also serving as the owner of REV Fitness, a personal training studio located in Southern California. On top of that, Brian’s profile also states that he graduated from the San Diego State University with a degree in Biology.

As for the program itself, it is separated into different manuals with each covering a topic in the weight loss trifecta plus an introduction manual. The introduction manual gives you a basic idea of how the whole 3 week program works and also clears up some diet concepts like the food pyramid and metabolism.

The diet manual forms the meat of the program and is basically composed of three phases, with each phase being one week long (for a total of 3 weeks and thus the title of the program). This diet plan tells you what you should be eating on a daily basis, how much you should be eating, and when you should be eating them. It identifies exactly which foods you need to eat in order to maximize the fat burning potential of your body, and also enumerates the exact foods you need to completely avoid due to their ability to stop or stall the body’s process of burning fat. In the first week alone, you are told to expect a weight drop of approximately 10 pounds.

According to the 3 Week Diet, you absolutely must create a calorie deficit in order to lose weight. In fact, this diet attempts to fool the body into going into starvation mode 24/7, and ultimately, have you lose around 1 pound of body fat each day. The main premise behind the creation of the 3 Week Diet is that a weight loss program must be able to produce visible and significant results fast to keep the dieter motivated and continue working towards their weight loss goals.

There’s also a section about calculating your lean body mass versus your fat percentage so that you can adjust your rapid weight loss plan based on your body type.

As for the exercise component covered in the workout manual, it’s mostly about body weight exercises and Kettlebell workouts. In other words, you won’t need gym equipment or heavy weights. Four different workout routines are provided within the program.

The mindset and motivation manual covers simple goal-setting basics and keeping a journal. None of it really stands out compared to the ones you typically see with other weight loss programs.


Our 3 Week Diet Review Verdict

3 Week Diet is a weight loss program designed for speed. It is designed to help you get rid of 12 to 23 pounds of body fat, take off 2 to 4 inches from the waistline, drop 2 to 3 sizes in dress size, and numerous other benefits — all in just 21 days. Although millions of individuals have supposedly benefited from this diet plan, the available and researchable evidence to back up this claim range from hard-to-find to non-existent. Extravagant claims with minimal evidence as well as risky methods without supportive scientific and medical basis are critical red flags. Therefore, we are really left with no other choice than to give 3 Week Diet a 1 out of 5 stars rating.

There are just a lot of unsubstantiated claims by this program. Phantom quotes from alleged doctors claiming that 20 pound weight loss in a week is possible and safe if done correctly (we know it’s possible because professional athletes like boxers and MMA fighters do it. But for a normal person, very doubtful), flabbergasting revelations that the entire diet and fitness industry is rigged by big companies, or that people don’t reach their ideal weight because they don’t see results fast enough; these are just some claims made in the program that the author expected us to believe without any evidentiary support.

With regards to other aspects of the program, we tried to contact the support team with some questions. We were simply met with silence. The email had no indication of bouncing, but we received no reply nonetheless.

There’s just too much question marks surrounding the program for anyone to even bother with it. Even if you have tried just about every single diet and exercise product out there and are desperate for anything new, this is just not a program worth putting your money on.
