  • Diet Manual– This contains the information needed to ensure you have a personalized diet plan for your body. It also shows you exactly what you need to eat and which foods you need to avoid at all costs because they shut off fat burning.
  • Workout Manual–Whilst optional, Flatt states that including the workouts helps you double your results so it is recommended. They consist of home based workouts but there is also a gym based version.

In total it takes 20 minutes 3-4 days per week which is great because it doesn’t require you to spend hours strapped to a treadmill.

Four Phrases:

If you want to lose weight quickly with this program then it is important to follow these four steps as it is mentioned by Brian Flatt. Here is detailed information of these phrases:

Phrase #1 – Liver Detoxification:

This phrase is created for all those men and women who want to lose weight quickly. In this phrase you will lose a lot of your weight. Some people found loss of 10-15 pounds after this phrase. This is because this phrase focuses on body cleansing especially liver (fat pumping organ).

In this phrase Brian Flatt recommends A, D and C vitamins that will detoxify your liver, increase insulin sensitivity and also increase body adrenal function for burning fat in the body.

In this phrase you will find list of 17 allowed vegetables and 6 allowed sources of protein. You have to follow this phrase for seven days before moving to the next phrase.

Phrase #2 – 24 Hours Fasting:

Once you complete first phrase then comes the second phrase that is 24 hours fasting. You have to start your fasting from the last meal of 7th day till the dinner on 8th day. Fasting cleanse your body and liver and also create environment in which body starts burning fat more efficiency.

At the dinner on 8th day you can eat whatever you want as there is no limitation but you have to keep your carbohydrate consumption under control.

Phrase #3 – Fat Fast:

Fat Fast is not a slang phrase instead it is a proven technique that is clinically and scientifically proven. You will find complete science behind this ‘Fat Fast’ technique in this section.

This phrase comes at 9th, 10th and 11th day and in this phrase you continue improving your liver efficiency while your body burning up stored fat from your belly and hips region.

After first two phrases your body burning up fat but on other hand it is also craving for fat. It is important to understand Fats doesn’t make your body to look fat. Once you provide 80% calories from fats (no trans-fat) your body will start signaling liver to burn fat for energy. As a result your liver will be burning fat not muscles for fueling other organs.

Phrase #4 – Your Unique BMR:

The last phrase will continue from day 12 to 21. This is the 9 days phrase in which you will be consuming calories that are based on your unique BMR and weight loss goals.

In this phrase Brian revealed 2 steps. In the first step you will be learning how to determine your BMR and in the second step Brian will show you how to create calorie deficient based on your unique BMR. This will help you to achieve your desired results quickly doesn’t matter either it is about getting six-pack abs or getting single digit body figure


Who Is the Ideal Candidate for the product?

The good thing about this diet is that it is accessible to everyone regardless of your age, body type or ethnicity.

Similarly, it also works regardless of your style of eating so even vegetarians and vegans can try the diet.

The people this diet will be best suited to are people who are sick of trying multiple diets and not getting the results your effort deserves. If you’re determined and commit to sticking to the plan as laid out for 21 days and you want to lose 12-23 pounds in that period then you are a good candidate provided you can commit to four twenty minute workouts per week.

On the flip side, if you think it’s a magic pill which you can buy and then sit around waiting for it to work its “magic” then this isn’t for you. As with all diets there is a requirement for you to change your habits as the habits that got you where you are today won’t enable you to get to where you want to go.

For that to happen you have to dedicate yourself to forming new habits that will take you to the promised land.
