Introducing the GreenSmoothieGirl Flash Fast: A Surprisingly Simple Way to Gain the Benefits of Fasting in Only 3 Days--Without Giving Up Food

People have been fasting since ancient times.

Today, millions of people fast for health, longevity, and detoxification.

Even a brief break from eating can help your body repair itself in impressive ways.

Most fasts have you going without food completely, and some even ban liquids, including water.

Modified fasting is different. You still get to consume a specific amount of food and nutrients every day, so you’re not suffering with an empty stomach. Modified fasting tricks your body into thinking you’re fasting.

Did you know? Fasting while eating is possible!
Did you know? Fasting while eating is possible!

Does the thought of fasting make you nervous?

You want to lose weight, relieve some aches and pains, decrease brain fog and feel more energetic. You’ve heard fasting can work wonders.

But you love food! And you hate going hungry. Don’t we all?

And even though you want to be healthy, you don’t want to fast if it means suffering through intense hunger pangs.

You don’t have time to pause your life for three days so you can take a break from food and drink only water. You don’t want to feel weak and depleted. You don’t want to interrupt your normal routine.

Does this mean fasting’s not for you?

Not anymore!

It's possible to enjoy the benefits of fasting, including...

  • Weight loss
  • Lowered disease risk
  • Reduced pain and inflammation
  • Greater mental clarity
  • Improved digestive health

...while still consuming small amounts of calories and nutrients in a specific way. All the benefits, none of the hunger.

Easy to Follow & Delicious 

The FLASH FAST is easy to follow and delicious. I had wanted to do a fast for several years but was afraid that I would be too hungry or I would not be able to follow the fast. This fast was so easy and my fears of doing a fast are gone.

Lara S.

Clean Your Insides

“HIGHLY RECOMMEND: Fasting is a way of cleaning house. If you take the time to shower daily, it only makes sense that you gotta take the time to clean the inside, too. It's a small inconvenience for the benefits you get.” 

Kay Grott

Fairview, TN

Continue Your Daily Routine with Ease

“This is much easier! It allows you to continue your daily routine with ease as compared to doing a water fast. Something that I could actually stick with!”

Annie S.

Atlanta, GA

Lose Weight & Feel Great 

“All the shakes and the bars kept me focused on what I had to have that I didn't notice what I was not having. The program was easy to follow and the individual packets were convenient, especially when I was on the go

The shakes were as simple or as creative as I wanted to make them and the flavor was outstanding. They were filling and nutritious and I never felt hungry and had plenty of energy. The bars were my special treat, they were delicious and they got me through any rough spots. Robyn's team answered my questions quickly and thoroughly and were very supportive. I lost 4 lbs. and I feel great.”

Carol C.

Rochester, NY

Enjoy Instant Results 

“I enjoyed doing the Flash Fast. The information and online support (facebook group) was very motivational. I also enjoyed learning the science behind it all. 

I instantly began to notice changes in my body, reduced inflammation, weight loss, and I became more mindful when I ate and how I felt after eating such healthy meals. Because of the instant results, I plan to do this fast monthly. I love the way I feel mentally, physically, emotionally, and spiritually.”

Terri R.

Enjoy A Flatter Belly

“4.6 lbs down and definite detoxing. 

I love how much flatter my belly is, and not just for looks. Belly fat is not healthy and hard to get rid of.”

Amy H.

Black Diamond, Alberta

Gain A Sense of Well-Being 

“This was an easy, fast, and inexpensive fast for me. Plus I lost some belly fat! 

The first day I felt positively euphoric and had high energy. In addition to my 30-minute walk I did about 30 minutes of strength training and enjoyed it. I had a sense of well-being throughout the fast and that feeling has lasted, now several days since I finished the fast. Anxiety has always been a problem for me and that has greatly improved.

I haven't gained back ANY of the weight I lost. It feels great to know that I did something to help me stay healthy.

Beverly S.


Experience Incredible Healing

“I didn't hesitate a minute when I heard about the 3-day Flash Fast. I have wanted to do a fast and got bogged down in all the research. The Flash Fast gave me the information and structure I was looking for to be successful

My purpose for doing the fast was to continue to heal my gut and body overall. In 3 days, I lost 3.5 lbs and 3.25 inches! I found my sleep to be more regular and restful—and I am dreaming and remembering my dreams. I felt clear-headed each day, crisp and fresh is what comes to mind. I worked in my garden each day and did my daily yoga—and still had energy for more. And the inflammation in my stomach is greatly reduced.”

Kim P.

Feel Better & Keep Your Sanity

8 Proven Benefits of Fasting for Your Health

  • #1

    Clears Your Body of Toxins, Mucous, Yeast, and Bacteria

    To thrive in today’s world, you need to clear toxins, chemicals, and carcinogens from your body. Fasting, or doing a modified fast like the Flash Fast, frees up 65% of the body’s energy from metabolic burden to focus on “autophagy,” or “self-eating” broken parts. Those parts are then rebuilt with millions of stem cells also created by the fasting process.

  • #2

    Increases Mental Clarity and Energy

    Researchers at the University of Texas have found that fasting corresponds with an improvement in mood, an increase in alertness, and a sense of serenity.

  • #3

    Increases Longevity

    Restricting the food intake of rats, mice, hamsters, dogs, fish, and humans extends their life span, according to a study at the Okinawa Institute of Science and Technology. When mice eat 30 to 40% fewer calories, they developed half the tumors and other diseases than mice who ate as normal. New research from the University of Southern California suggests that fasting could improve longevity in humans, too.

  • #4

    Enhances the Immune System and Lowers Inflammation

    A 2014 study found that fasting causes the immune system to regenerate as stem cells shift from a dormant state to a state of self-renewal. A 2019 study also showed an overall drop in inflammation.

  • #5

    Fights Cancer Cells

    Periodic fasting helps prevent cancer and increases the effectiveness of some cancer therapies, according to researchers at USC.

  • #6

    Improves Markers Associated with Heart Disease

    In another USC study, participants completed three modified fasting cycles. In addition to weight loss, subjects reduced their blood pressure, total cholesterol, and C-reactive protein (a marker of inflammation).

  • #7

    Decreases Diabetes Risk

    Several studies suggest that periods of fasting improve insulin sensitivity, decreasing the risk of developing diabetes.

  • number-8

    Protects Against Neurological Disease

    One study showed how modified fasting can reduce or even eliminate multiple sclerosis symptoms, as well as rebuild damaged myelin sheath in spinal cords of patients with neurodegenerative disease. This is incredibly exciting because nothing else in modern medicine has been successful at reversing neurodegenerative disease or rebuilding the nervous system.

  • And that’s just the beginning! Many of my followers are ordering Flash Fast once a month for weight loss or on a quarterly basis for disease prevention. The long-term benefits are endless!

"The most important and revolutionary health breakthrough so far this century."

-Robyn Openshaw

A Note from Robyn Openshaw, Detoxification Expert and Creator of Flash Fast

I’ve been studying human detoxification for 25 years, and in that time, I’ve found two serious game-changers.

The first? Green smoothies. I’ve spent my career promoting them as a powerful tool for health and healing.

The second? Modified fasting. I’m not exaggerating when I say this is the most important and revolutionary health breakthrough I’ve encountered so far this century.

The GreenSmoothieGirl, Robyn Openshaw.
The GreenSmoothieGirl, Robyn Openshaw.

Fasting is nothing new to me. I’ve done it for years, even spending time at an ashram in Texas for days at a time while I consumed nothing but water. That kind of fasting is amazing for your health, but it’s also hard. You’re hungry. You have no energy.

Even as an experienced faster, water fasting kicks my butt. It completely zaps me of energy.

This new approach is totally different. It lets me live my life and feel great while doing it! And, it is very affordable so I can do it often (which has so many health benefits!)

I developed Flash Fast because I’m so excited about modified fasting. It’s anti-aging and disease-preventing. It’s the second great health-and-wellness discovery of my lifetime.

Why You Need to Detox in Today’s World

The Flash Fast is a healthy way to detoxify. Here’s why that matters:

Your kidneys and liver are constantly working to keep your body free of toxins. They’re overloaded; in our modern world, they’re getting way more toxic input than they can take.

Assuming your liver, kidneys, and other detoxification systems can handle all the chemicals and pollutants they encounter each day is like saying a Model T Ford can run forever in 1930s Dust Bowl conditions without so much as a tune-up.

We’re living in a toxic soup, and our organs of elimination simply can’t keep up. Escalating disease rates are the consequence.

Flash Fast supports your body as it cleanses itself. When your cells and organs don’t have to worry about digesting the food you eat every day, they can reboot and focus all that energy on healing.

In this overly toxic world, doing a fast on a regular basis is so important, that is why I made Flash Fast so affordable. Can you imagine the health benefits of having this in your quarterly or even monthly routine?
