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.

This 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.

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?

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 guide. 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. We cover some of these benefits in detail with our random food generator, including how easy it is to get a balanced diet when you have the assistance of a smart nutrition coach or an automatic meal planner.

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 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.
