3 Week Diet Reviews: Best Meal Plan To Lose 20 Pounds of Body Fat in Just 21 Days – If you’re looking to lose weight, you’ve probably tried a diet or two. Some may work to an extent, but the progress is probably slow and the diet is hard to follow. Eventually, you get discouraged and give up.

A new program called the 3 Week Diet will change how you think of diets forever. This revolutionary program is easy to follow and is guaranteed to help you burn fat and lose weight quickly.

3 Week Diet Plan Overview

The plan’s creator is Brian Flatt. Brian has been working in the diet and fitness industry since 1999, as a certified personal trainer, a certified sports nutritionist, an author, and a speaker.

During his time in the industry, he’s seen firsthand what doesn’t work. He used science combined with experience to create a new program that does work.

The plan is an easy-to-follow complete system involving both diet and exercise that is proven to lead to rapid fat loss. Brian teaches you why much of the so-called wisdom out there about dieting and weight loss is wrong.

This bad information is what makes the diet industry a multi-billion dollar market. Then, he teaches what the right way to lose weight is in a simple, step-by-step fashion.

3 Week Diet Details

The plan offers a digital pdf download of four distinct manuals. These are an Introduction Manual, a Diet Manual, a Workout Manual, and a Mindset & Motivation Manual. These four parts of the program seamlessly work together to help create the new you.

It’s clear that the 3Week Diet was built on a solid foundation of science. There is a recognition that the extra weight you carry is probably not your fault.

Brian explains that some of the common reasons for carrying extra weight are things like cellular inflammation and unbalanced hormones. This approach is refreshing since so many diet books can feel judgmental.

Rather than blaming you, this weight loss program teaches you the science in an approachable way and then gives you an actionable diet plans for how to succeed to achieve your goal.

A major cliche that Brian refutes with the 3 Week Diet is the idea that eating less and exercising more is all you need.

This standard advice can only help to a certain extent, and for many, this advice is practically useless.

He teaches that not all calories are equal and teaches you why. Knowing what to eat is key to success.

In addition to knowing what kinds of foods help or hinder weight loss, the 3 Week Diet includes some other techniques like intermittent fasting and selective supplementation.

There are also relatively short, easy to follow workout plans included. Every part of the plan is easy to follow with clear, step-by-step instructions.

A major reason this program works is that effort leads directly to reward. This can be true with many diet programs, but the connection between effort and reward is usually painfully slow.

With 3 Week Diet by Brian Flatt, you start to see significant results right away. This immediate reward motivates you to keep going. This reward system is what makes sticking to this diet easier than sticking to other diets.

The plan is called the 3Week Diet because it’s built around a 21-day time period. If you still have weight to lose, you can absolutely continue the program past the first three weeks and Brian Flatt describes how to do it.

Moving to the exercise portion, while the diet alone will transform your body into a fat-burning machine, the exercise routines delivered in the e-guide could double your results. Specifically, Brian Flatt explains that most diets fail is because the volume of exercise necessary to make the diet work may require a large amount of time. Fact is, regarding exercise, weight loss is controlled by intensity, not time. Hence, by using The 3 Week Diet, you will discover some real-world proven body shaping and fat burning workouts within just 20 to 30 minutes each day and just 3 days per week.

The last but not least element that determines the effectiveness of weight loss is the motivation of losing weight and mindset.

Inside the e-guide, the author uncovers to people the truth about weight loss and the way that people get fat. To put in simple words, the first reason why people gain weight is that they regularly consume more calories than their bodies actually need. Thus, in this e-guide, you will get to know the exact manner to calculate how many calories your own body needs each day so that you could instantly and consciously put an end to any future weight gain, once and for all. The second reason that you are becoming fat day by day is as most of you never give your body any time to really burn a way the fat you have accumulated.

Once you acknowledge how your body gets fat, you will know how to prevent it. Brian Flatt, the author points out the role of different types of nutrients towards weight loss, what the human body needs and what it does not. The 3 Week Diet is about maximizing the nutrients that the human body needs whilst restricting those that it does not. Actually, the rule behind this program is about eating the right foods in the proper volume and of course, at the right time. If done exactly, you will be able to put your body in to a natural 24/7 fat burning mode.

The author reveals to learners the role and effects of protein which are the basic foundation of the body’s cells, organs, and tissues. While the human body could survive without consuming another carbohydrate and also could last for extended periods without taking fat, just lack of protein in the diet plan may cause the degeneration of the muscle tissue as well as organs. Thus, acknowledging the importance of protein towards the body is so critical for effective weight loss. This e-book will provide you with everything necessary to help you take control of consuming protein correctly. In addition to proteins, people will discover how consuming of fat, essential fatty acids, fiber, water, and carbohydrates influences the overall health, in general, and weight loss effectiveness, in particular.

In other words, the author also walks learners through a process of exploring the functions of metabolism and what impacts metabolism. In reality, nutrients and metabolism are two main factors affecting fat loss. When it comes to fat loss, there are several critical rules you should apply in order to get a healthy weight, which are:

  • Rule 1: burning fat and losing weight means that you should create a calorie deficit over time.
  • Rule 2: before your body starts burning fat, the fat has to be mobilized. It is the initial step in the common weight loss process. Mobilizing the body fat and using that fat for energy that your body has to consume, you will be healthy and leaner.
  • Rule 3: you could easily take control of how much fat you will mobilize.
  • Rule 4: You must keep the insulin low and catecholamines high
