The Complete 3 Week Diet System Review Below:

The 3 Week Diet System really provides great value considering it comes complete with 4 manuals. These include the 3 Week Diet Introduction Manual, the Diet Manual, the Workout Manual and the Mindset and Motivational Manual.  For those of you who don’t like to exercise you will be happy to know that author Brian Flatt claims you can still get excellent weight loss results without participating in the exercise component of this system. Ok, so let’s break it down a little further.

The 3 Week Diet Introduction Manual helps you understand the science behind how we gain and lose weight.  It breaks down complex nutritional concepts and displays them in an easy to follow foolproof way. If you are one of those people who prefer to read diets filled with scientific jargon than I am sorry to say that you may want to look elsewhere. This 3 week Diet System seems to be worded and designed more for people who just want an easy to follow step by step plan to get rid of stubborn body fat fast.  The 3 Week Diet Introduction manual also contains information on certain supplements that can be incorporated into the system to help you spruce up your metabolism.  We investigated the price of these supplements and are happy to report that they are all quite cheap and easily accessible. To be honest, these supplements probably aren’t even really necessary as most of the fat loss is achieved through macronutrient (particularly carbohydrate) manipulation techniques.

The 3 Week Diet Manual shows you exactly how to calculate your lean body mass and determine just what percentage of body fat you are actually carrying around on your body.  We really like how this part of the 3 Week Diet System sets you up with a completely individualised plan that is tailored to your specific body type.  So no matter what shape or size you are the 3 Week Diet will suit you.  The 3 Week Diet Manual explains plain and simply exactly what you need to eat, how much you should eat and when you should eat it. This diet manual uncovers some real cool little tricks about the timing of food consumption and how this can optimize the fat burning process. Basically you will become a 24/7 fat burning machine by learning how to use your stored body fat for fuel.  You will also find information on what foods to eat and more importantly the ones you should avoid in order to get the claimed results of 12-23 pounds in only 21 days.

This 3 Week Diet Manual also outlines what vitamin supplements you could also take to help you maximise your weightloss results. We were happy to see that these supplements are also very cheap and easily accessible.  Some people have reported that they have actually saved money while on this diet due to the fact that there is such little food wastage.  So no more throwing away outdated food week after week.  Who doesn’t want a little bit of extra cash to spend on the important things like ourselves or the ones we love.

As I mentioned earlier,  the 3 Week Diet system includes a Workout Manual which caters for those who don’t like to go to the gym and would prefer to workout from home.  This 3 Week Diet Workout Manual seems to be designed for the absolute beginner. The system contains exercises that only require 20 minutes of your time, 4 days a week.  So if you are a gym junkie looking for a hard-core workout you may want to look elsewhere.   For those who are unable to exercise due to illness/injury you will be happy to now that Brian Flatt claims that excellent weight loss results can still be achieved without the exercise component. Remember weight loss is 95% diet and 5% exercise.

Finally, as you know our team are very passionate about the importance of getting in the right frame of mind when embarking on a weight loss journey. We are happy to let you know that the 3 Week Diet Systems Mindset and Motivational Manual has all the tips, tricks and tools to ensure you remain motivated and achieve your weight loss goals. The Mindset Manual helps you establish healthy behavioural changes over the course of the 3 week program. The 3 Week Diet System is based on the scientific principles which state that it takes 21 days to form healthy habits while concurrently breaking  poor habits and lifestyle choices. They claim that these healthy behavioural changes can carry over to healthy learnt habits that you can then apply for the rest of your life.  So all you have to do is stick with the diet for 3 weeks. That’s it, just 21 days!   In this short period of time you can lose some serious fat weight and strengthen your resolve while you’re at it.
