What is the 3 Week Diet?

The 3 Week Diet Program is a manual-based system created by Brain Flatt which is designed to help consumers lose body weight and body fat in twenty-one days.

It is a diet system with specific manuals focusing on certain aspects of weight loss. The program consists of four instruction-based manuals, including the:

  • Introduction Manual
  • Diet Manual
  • Workout Manual
  • Mindset & Motivation Manual

Consumers can purchase the entire set, which is also available as a digital download, and start working on their weight loss with an accurately-designed meal plan.

How Did 3 Week Diet Start?

Brain Flatt, a certified personal trainer and sports nutritionist, created the 3-Week Diet.

According to him, other weight loss programs or diet plans are more targeted towards a slow approach to weight loss and do not help the user in shedding stubborn stored fat.

Those fatty acids from the stored fat combine with glycerol molecules and form a triglyceride. Thus, the 3-week diet plan is specially designed to work on those triglycerides, which normal diet plans are not able to target.

3 Week Diet Claims

The 3 Week Diet claims that the user will be able to accomplish the following in twenty-one days, as compared to what other diet plan programs do in two to three months:

  • Lose 12-23 pounds of pure body fat
  • Lose 2-4 inches from the waistline
  • Drop 2-3 dress sizes
  • Increased muscle tone
  • Decreased cellulite
  • Improve metabolism
  • Get healthy skin and hair
  • Improve your cholesterol levels

How Does the 3 Week Diet Work?

According to the 3 Week Diet Plan Program, there are four stages in this plan. The first stage contains a detailed explanation of what type of food users are supposed to eat.

It lasts for seven days and it specializes in eliminating toxins and clearing waste from the body. Certain foods which users can eat are as follows:

  • Chicken
  • Broccoli
  • Eggs
  • Spinach
  • Tomatoes
  • Turkey
  • Cabbage
  • Beef

The second stage makes the users do ‘The 24 Hour Fast,’ in which you are supposed to skip meals for one day. Certainly, this might be difficult for users who are doing this for the first time.

In the third stage, which lasts for two days, users are supposed to eat food with more calories and which might contain more than 70% fat.

This might sound contradictory to the claim of this product, though research proves that High Fat, Low-Carb diets help in losing weight.

The last stage is about adding more food to your daily intake schedule but with a precise calorie consumption chart.

The 3 Week Diet Plan also asserts that the users need not worry about gaining weight once again after losing it, as they can easily repeat Stage 1 and Stage 2 and can reduce their weight swiftly.

What is Included in the 3 Week Diet Program?

The 3-week diet system consists of four books with a specific aim. There is an Instruction Manual book which focuses on science and techniques behind weight loss.
