The 3 Week Diet Review – Does It Really Work or Just BS?

The 3 Week Diet is an ultra-effective program that is often recommended for anyone looking to burn fat and lose weight quickly.

Brian Flatt, the creator claims the system is extremely fast, and produces visible results in just a week.

This will apparently help you reach a level of fat loss you never thought possible in just 21 days.

Now of course that sounds great but the purpose of the 3 week diet review is to see if it can actually give you the results they promise.

Brian Flatt’s 3 Week Diet is a weight loss system based on various manuals. It says it can help you lose up to 33 pounds in just 21 days — so we had to know what the catch is.

Some people reported results, but low-calorie diets like this one can often be too much for some.

What is the 3 Week Diet?

The 3 Week Diet Program is a manual-based system created by Brain Flatt which is designed to help consumers lose body weight and body fat in twenty-one days.

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

  • Introduction Manual
  • Diet Manual
  • Workout Manual
  • Mindset & Motivation Manual

Consumers can purchase the entire set, which is also available as a digital download, and start working on their weight loss with an accurately-designed meal plan.

How Did 3 Week Diet Start?

Brain Flatt, a certified personal trainer and sports nutritionist, created the 3-Week Diet.

According to him, other weight loss programs or diet plans are more targeted towards a slow approach to weight loss and do not help the user in shedding stubborn stored fat.

Those fatty acids from the stored fat combine with glycerol molecules and form a triglyceride. Thus, the 3-week diet plan is specially designed to work on those triglycerides, which normal diet plans are not able to target.

Who Is Brian Flatt?

From the above paragraph, you get the idea of who Brian is in regard to this program that we are taking a look at. But who really is this person behind the program?

Brain Flatt is a personal trainer, a nutritionist, a health coach as well as the author that is behind The 3 Week Diet system. He is a graduate of the San Diego State University where he graduated with a degree in Biology.

He took a career in the industry of fitness since 1990’s. In the recent past, he was a fitness studio manager in southern California. A studio by the name, ‘Rev Fitness.’

In accordance to this eBook of his, the claim by Flatt is that he was able to read well above 500 medical studies, dozens of books on diet and making reviews of diet systems, gadgets, programs, potions and pills in their hundreds.

Following the in-depth research he conducted and the desire he had of creating a system for weight loss for any person that had a problem in weight, he was able to develop The 3 Week Diet.

As an extreme diet whose basing is on science, this system includes some practices and techniques that are used by the likes of celebrities, body builders and gurus in fitness. All in order to quickly lose body fat.

The designing of the four manuals was particularly to cause your body to burn fat throughout the day, every day of the week.

During the initial seven days, this diet should compel your body to shed away a pound or two in a day. Thereafter, it will be three-fourths to a whole pound.

3 Week Diet Claims

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

  • Improve your cholesterol levels

What is Included in the 3 Week Diet Program?

The 3-week diet system consists of four books with a specific aim. There is an Instruction Manual book which focuses on science and techniques behind weight loss.

It provides details about nutrients which will be required and worked upon during this program.

The second book is the Diet Manual, which provides comprehensive details and provides a list of food to eat every day, the specific quantity of food to eat, and the timing to follow regarding the meals.

It’s a specially-customized weight loss plan targeted through a thorough meal plan.

The third book in 3 Week Diet plan consists of a workout manual which has special small exercises and workout plans which can be done in a gym or at home.

It also claims to have a unique Midsection Miracle Workout which has two special abs exercises to get six-pack abs.

The last book in the 3 Week Diet program is a Mindset & Motivational Manual, which includes a lot of motivational tips, tricks and secrets.

What is the Restriction of Carbohydrates in a diet?

Carbs are fuel for your body, as your body turns them into energy. But while they fuel your body, they also get stored as fat, which means if you eat a lot of them, you’re going to pack on the pounds. 

Carbohydrates are found in so many foods: bread, pasta, potatoes, pasta, muffins, chips, and so many other things.

Cutting out these foods can significantly aid in weight loss. That’s because when you stop eating them, your body can’t turn them into fat. Instead, you’ll burn off the fat that is already stored in your body, which means fast weight loss.

It’s because of this that The 3 Week Diet is so keenly focused on significantly reducing your carbohydrate intake. 

How Does the 3 Week Diet Work?

According to the 3 Week Diet Plan Program, there are four stages in this plan. The first stage contains a detailed explanation of what type of food users are supposed to eat.

It lasts for seven days and it specializes in eliminating toxins and clearing waste from the body. Certain foods which users can eat are as follows:

  • Chicken
  • Broccoli
  • Eggs
  • Spinach
  • Tomatoes
  • Turkey
  • Cabbage
  • Beef

The second stage makes the users do ‘The 24 Hour Fast,’ in which you are supposed to skip meals for one day. Certainly, this might be difficult for users who are doing this for the first time.

In the third stage, which lasts for two days, users are supposed to eat food with more calories and which might contain more than 70% fat.

This might sound contradictory to the claim of this product, though research proves that High Fat, Low-Carb diets help in losing weight.

The last stage is about adding more food to your daily intake schedule but with a precise calorie consumption chart.

The 3 Week Diet Plan also asserts that the users need not worry about gaining weight once again after losing it, as they can easily repeat Stage 1 and Stage 2 and can reduce their weight swiftly.

The 3 Week Diet is comprised of 4 phases;

1. Detoxing (Day 1-7 )

Phase one will last 7 days!

You will be given a detailed list of what foods you can eat and how you should cook them.

The purpose of the first week is to detox your entire body and eliminate any toxins and waste.

2. Fast For 24 Hours (Day 8)

After a full week of detoxing your body you will then fast for a full 24 hours.

Your fast will start immediately after your last meal on day 7. 

So for example if day 7 lands on Sunday and you eat your last meal at 7pm then you are not allowed to consume any calories until 7pm the next day.

Some people might struggle with that idea but it’s actually a lot easier than you think.

The reason for this fast is to give your digestive system a rest and finish cleansing any toxins still left in your body.

3. Increase Fat Intake (Day 9-11)

Okay so you detoxed for 7 days then fasted for a full 24 hours, what’s next?

Well you can finally break you fast and start eating again. During this phase, for 3 days your diet will consist of 80% fats.

Now when we say “fats” we don’t mean burgers and fries.

Your diet will be filled with high quality, HEALTHY fats. The reason for this is you want your body to start running off of fat instead of carbs and sugar.

Since you cleansed your body of all that and you haven’t eaten for 24 hours your body is not looking for a source of energy. That’s where that fats come.

4. Caloric Deficit (Day 12-21)

By day 12 your body should be rewired to run off of healthy fats instead of carbs. 

This state is called ketosis and it is the most optimal state for you to burn fat quickly and effectively!

Phase 4 is the longest in the program, lasting 9 days. During this last stretch things will become a little more customized for your needs.

You will go into a caloric deficit depending on your personal Basal Metabolic Rate (BMR).

Your BMR is an estimate of how many calories your body burns at rest throughout the day. 

The 3 Week Diet will show you how take your BMR and get into the correct caloric deficit to lose as much fat possible in the last 9 days of the program.

  1. I think you can really lose something in 3 weeks most especially when you are on a strict diet and have been training on the gym. I am currently on intermittent fasting and I have lost quite a few lbs. Im happy and at the same time I go to the gym also for some light workout. Im not on the heavy side so this works well for me.
