4 Phases in Which This 3-Week Diet Works

Phase #1 – Detox Your Liver (Days 1-7)

These powerful vitamins increase insulin sensitivity and adrenal function to turn your body into a fat burning machine. You’ll also eat a ton of nourishing vegetables during this phase (17 different types to be exact) and lean protein.

The best part? Phase one lasts just seven days!

Phase #2 – Fasting for 24 Hours (Day 8)

Once you’ve cleansed your body, you can move onto phase two: one day fast. Fasting starts after your last meal on the 7th day of the program and lasts just 24 hours.

Keep in mind that a quick fast will give your digestive system a rest and it will cleanse any toxins you may have left in your body after the first phase.

Because your fasting begins before you will go to sleep, it is much easier to last 24 hours without any food.

Phase #3 – Fat Fast Diet (Days 9-11)

video tips from brian flatPhase 3 is the Fat Fast Diet phase. You’ll start this on the 9th day of the program. It lasts just three days, but you’ll use scientifically proven weight loss techniques that will kick-start your results.

What does phase 3 look like?

You’ll continue cleansing your liver and getting rid of those built-up toxins that are weighing you down – literally.

Thanks to this, you will start burning that stored fat in your belly and hips. For three days, you’ll eat a diet that consists of 80% calories from fat.

I know what you’re thinking – won’t that make me gain more weight?

No! In fact, this will start signaling your liver to start burning it for fuel. The outcomes? You burn even more body fat, and the pounds start melting off.

Phase #4 – Calorie Restriction Based on Your BMR (Days 12-21)

Phase four will last from day 12 to 21. For the next nine days, you’ll be eating a diet that’s designed for your own unique BMR and your weight loss goals.

What is BMR, you ask?

BMR stands for Basal Metabolic Rate. It measures your own unique metabolic rate. How does this rate benefit you?

Luckily, the your personal BMR lets you calculate exactly how many calories you need to consume to reach your goals. Don’t worry – Brian teaches you exactly how to calculate your own basal metabolic rate, so you can achieve the results you want.

Now you know how the program works, but what do you get when you buy it?

The Standard Package costs just $47.00 – reduced from $97 – and it comes with four PDF files to guide you through your weight loss journey.
