Overview and Features: What is the 3 Week Diet System?

The 3 Week Diet was created by Brian Flatt, a personal trainer, and a coach that specializes in nutrition and health. Mr. Flatt claims that by following his diet plan, you can lose as much as 23 pounds of body fat in just 21 days. 

The 3 Week Diet is a combination of intermittent fasting, a severe reduction in carbs, intermittent fasting, supplements, and of course, exercise. Flatt claims that his diet plan lets you know precisely what and how much you should be eating, and when you should be eating to achieve the weight loss goals that the plan promises. Flatt also illustrates different exercise routines that can help you melt off fat fast. 

The 3 Week Diet System comes with the following materials: 

  • An introductory manual. This manual isn’t just an introduction to the 3 week diet; instead, it sheds light on the science that allows you to gain and lose weight in the first place. It also tells you what you need to do to effectively tackle body fat and actually get rid of it. The introductory manual also shares the key nutrients what your body needs in order to have success with the diet, why those nutrients are beneficial for weight loss, and how they work. 
  • A diet guide. In this guide, you’ll learn exactly how to go about losing weight in just 21 days. You’ll find out how to determine your lean body mass and your percentage of body fat. You’ll also find a weight loss plan that is customized to your specific body type, which will tell you precisely what and how much you should be eating every day. Additionally, you’ll learn when you should be eating the suggested foods. 

What about the 3 week diet booklet?

  • A workout instructional booklet. This workout book offers exercises that are specifically meant to target stubborn body fat. These exercises work in conjunction with the diet manual so that you can see real results. These exercises take just 20 minutes to complete, and they only have to be done 3 or 4 times each week. 
  • A motivational manual. This manual is meant to help change your mindset because the key to successful weight loss, according to Brian Flatt, is changing the way you think. Once you change the way you think, you can stick to the goals that you have set for yourself. The tips offered in this manual will not only help you stay motivated throughout the 3 week diet, but it will also keep you motivated so that you can stick to your lifestyle changes once the menu itself is complete. 

You get all of these weight loss materials for the low price of just $47. And since Flatt offers a money back guarantee, it seems like a pretty sound investment. 

The Man Behind The 3 Week Diet Plan: Brian Flatt

Brian Flatt has been working in the weight loss and fitness industry since 1999, where he started out as a personal trainer and weight loss guide in California. He’s certified as a sports nutritionist, as well as a personal trainer. 

His passion for fitness led him to open up his workout facility, R.E.V Fitness. It also led him to develop his own revolutionary diet plan, which apparently is known as The 3 Week Diet. 

Flatt claims that he read more than 500 nutritional and medical studies a month, and he used the information that he gained from these studies to develop his own weight loss plan. 

 

How Does It Work?

So, how exactly do you lose weight on this diet in 3 weeks? It involves four different stages of phases. Each phase lasts a different period. 

  • Phase 1: The first phase lasts for 7 days, and many people say that it’s the hardest phase of the four. That makes sense because it’s the introduction to the diet plan and involves some pretty significant changes to your diet and lifestyle. 
  • Phase 2: This is the shortest phase, as it only lasts for 1 day; however, despite its short duration, many people claim that it’s one of the most effective 3 week diet. 
  • Phase 3: This phase of the plan lasts for three days, depending on your unique body type. It involves one-of-a-kind approaches to diet and exercise that are sure to be different than any other diet plan you have tried in the past. 
  • Phase 4: The fourth and final stage of this diet system spans a 10 day period. During this stage, you are supposed to learn tips and tricks that will help you keep the weight off moving forward. 

There are two key elements involved with this diet that stand out and make it such an effective way to lose a noticeable amount of weight. Those two diet factors are: restricting carbohydrates and intermittent fasting. 

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. 

What is Intermittent Fasting?

Intermittent Fasting

As the name suggests, intermittent fasting refers to a cessation in eating for small periods of time. For instance, you might fast for a day or two during one week on this plan. The amount of time you should fast depends on your specific body type. Which this particular diet plan will help you figure out, and will also tell you how long you should fast intermittently. Sometimes, fasting may occur during a specific time frame on a given day, or you might stop eating for a full day. 

The idea behind this intermittent fasting is to encourage your body to use and burn off its fat reserves, which will lead to weight loss. Not eating over a span of time can also help you gain better control of your diet. For instance, if you aren’t eating a big breakfast packed with high-calorie and high-carbohydrate foods (which many people tend to eat in the morning. Think waffles, pancakes, bagels, muffins…), you can supposedly retrain your brain to think differently about food. 

At first, fasting might seem complicated, but as your body and brain get used to it, it actually becomes a lot easier. Plus, you’ll find that you will notice a significant reduction in how frequently and strongly you feel the need to eat. 

By following the intermittent fasting, restricting your carb intake, increasing protein intake, eating the foods that are recommended, and engaging in the suggested exercises presented in Brian Flatt’s diet plan, you can stand to lose a significant amount of weight in just 21 days. 

Will You Really Lose Weight on the 3 week diet? 

No matter what diet plan you are trying, there’s no guarantee that you will lose weight. However, as long as you adhere to the rules of this diet plan and are strict about them, then yes, you can lose weight in just three weeks. How much weight can you lose? That depends on your body type and your health. 

An important note about health: the 3 week diet isn’t meant for everyone. If you are suffering from a medical condition, such as diabetes or high blood pressure, you should consult with a doctor before starting The 3 Week Diet. Your dietary needs may not make the system a safe way for you to lose weight. 

Something else worth noting: While you may see results, they may only be temporary. While the plan does aim to teach you strategies to maintain your weight loss, it kind of does a subpar job. Plus, if you start eating unhealthily again or not exercising, you are going to put the weight back on. For example, if you start eating lots of carbs and spend more time sitting in front of the TV than you do being active, then it’s pretty much guaranteed that you are going to put any weight you lost back on. 

This diet plan is an excellent way to jumpstart weight loss and a healthy lifestyle, but it isn’t intended to be a long-term plan. With that said, by following this diet in 3 weeks and then making serious changes to your lifestyle that include a menu full of healthy, low-calorie foods and an exercise regiment, you can see lasting weight loss results. 

What about the diets science?

The one problem with this partiuclar 3 week diet is that Brian Flatt claims to have use science to develop his system; however, he doesn’t really explain what science he uses. He kind of just states that he read a lot of scientific research, but doesn’t back this statement up with any quantifiable information. Has he really done a lot of research and reading? Probably. But what research has he investigated and what has he read? Nobody really knows. 

Feeling a bit skeptical about Mr. Flatt’s ideas? While nobody knows if his claims for extensively studying the science behind weight loss are true, upon investigating his diet, the methods that he suggests using are actually true. For instance, eating low-calorie, low-carb, and high fat (healthy fats) foods is known to be an effective way to lose weight. A quick search on the Internet will prove these weight loss strategies are true. 

What Will You Gain From This Diet System? 

Of course, the main goal of flat’s 3 week diet plan is noticeable weight loss in just 21 days. There’s definitely a chance that you could lose the whopping 23 pounds that Brian Flatt claims is possible. You may lose less than that though; maybe 9 pounds, maybe 5 pounds. The key here is that you should lose some amount of weight. But again, you do have to stick to the program if you really want to see results. 

In addition to losing weight (hopefully), you will also gain these added benefits: 

  • You’ll get in the right mindset for weight loss. The motivational guide really is just that: motivational. One of the reasons many diets fail is because people are not in the right state of mind. I think that’s one of the best things about this diet system. It really helps you change your way of thinking and gets you excited about the weight loss journey. 
  • You’ll feel great! Even if you don’t lose the amount of weight that the system advertises you can, exercising and eating right will definitely make you feel good. Nourishing your body with the right foods and being active always make you feel better. You’ll have more energy; feel more inspired. You’ll just notice a definite change in your overall personality and outlook on life.

The Pros and Cons Of The 3 Week Diet

In this portion of the 3 Week Diet review, let’s take a look at the good and bad of the program. 

The Pros of a 21 day weightloss challenge meal plan

  • The possibility of seeing fast weight loss results
  • A thoughtfully designed diet and exercise program
  • You’ll gain some pretty impressive health benefits that extend beyond weight loss
  • It’s highly motivational, which is a huge plus
  • The system is quite affordable, especially when compared to other weight loss plans
  • All of the information is presented in a very easy to follow format; it’s very straightforward and to the point. 
  • Money back guarantee. This is a great feature because you won’t feel like you’ve wasted your money if you don’t see results. If you’re not satisfied for any reason or if you don’t see any results, you will be fully refunded, which is awesome. 

The Cons: Is it bad to lose 10 pounds in 3 weeks?

  • The 3 week diet plan isn’t meant for everyone. It isn’t recommended for people who have health conditions, such as DM (Diabetes Mellitus) and high blood pressure. If you do have a health issue, make sure you consult with your doctor before investing in this program. 
  • There aren’t any videos to follow. There are diagrams, but videos would have made it a lot easier to understand, especially concerning the exercises. 
  • Brian Flatt doesn’t offer any solid proof of the type of scientific information that he based his plan on. You kind of have to take him at his word on the facts. This is the trust you need regarding the nature of the reading and research that he’s done. 
Three Week Diet Conclusion and Rating

ASCVS.org Product Rating: (4.5/5)

3 Week DietNow that’s you’ve had a good look at what the 3 Week Diet plan is all about, you’re probably wondering if you should purchase it. 

In a word: yes! Like every other diet plan out there, it may not be for everyone; however, it really is a lot better than many of the other systems that are on the market. The techniques that are involved in this program are really effective for weight loss. If you use them all together and really adhere to them, you can see a significant amount of weight loss in a short period of time. Plus, you could see weight loss results that last a long time. What’s more, it will help to put you in the right frame of mind for losing weight. The motivational information really does what it’s intended to: motivate you to achieve your weight loss goals. If nothing else, this feature of the system really does make it worth the investment. 


Fasting FAQ's: Why isn't it free?
  • Why can’t I get it for free?

You could get it for free if you made it yourself. I warn you; it took months of research and trial and error by personal trainers and health coaches to build this plan. Which is why it costs money to maintain it and recoup the investment. Not everything is free; you could quickly hop on bodybuilding.com and grab a generic health guide. Many people grab these guides and quickly discover they will not offer the precision or facts needed actually to achieve their goals.

ASCVS advocates for this program because we know it works for the general public. We used to produce custom plans for people who wanted to trim down and quickly realized a pattern. The fact that this pattern is exactly what this diet offer makes it even easier for us to educate you.

Although dietary weight loss counseling usually employs a 500-1000 kcal/d energy deficit to induce weight loss of 0.5-1 kg/wk, this rate of weight loss is rarely achieved in research settings. Biological factors, such as changes in metabolic rate, are partly responsible but would account for a small deviation from expected weight loss. There must be other factors, behavioral or related to study design and implementation that affect the rate of weight loss observed. [ncbi]

 

  • Are their alternative options for weight loss

Of course, the internet is packed with options to help you trim down. In fact on websites like http://www.eatingwell.com/, they have over a dozen diets alone. Now just as we mention before options do not equate to the same solution. Time and time again you see people constantly juggle diets. This diet is one you can stick with continuously to keep maintaining your perfect body. If you decide to combine this diet with a fitness plan you can see even better results that can last a lifetime.

  • Could I lose 20 pounds in three weeks?

Depending on the deficit, you can expect to lose between .5 to 1kg a week. Now one sizeable deciding factor is if you also include vigorous aerobic and anaerobic training to supplement the diet. It is hard to make promises on how much weight you will lose. The results of this can best be obtained by stuck to the program religiously. It has been observed in other clients that they aimed to lose 10 pounds. 10 pounds isn’t too much of a hurdle when you have the proper education. ASCVS staff has even lost between 3 pounds to 17 on this program.

  • How much can I lose without exercise

This program is built for people who are too busy to exercise. That doesn’t mean that being active would not help you reach your goals faster. Being active is the best supplement to a healthy diet for anyone who is looking into a mass gainer or is trying to lose fat.

  • Is this also the orange diet?

The orange diet is entirely different from this. The orange menu could be seen as a less informed version of 3WD.
