The Flash Fast Is A Modified Fast—What’s That? 

A “modified fast” tricks your body into thinking you’re fasting. So you get to consume a specific amount of food and nutrients. And you don’t have to give up the pleasure and satiety of eating. 

It’s a LOT easier than traditional fasting (when you eat nothing). And it’s safer, too. 

It’s Not Just Hype—Flash Fasting Has Proven Benefits, Backed by Science

Everyone is talking about fasting. Lots of people are doing it—and getting results. 

Now is YOUR time to try fasting and see what everyone is talking about. Because you don’t want to miss out on these benefits: 

Our initial beta testers for the Flash Fast reported losing between 3 to 7 pounds, reduced joint pain, improved digestion, better sleep, and more energy—all in only 3 days! 

You can learn all about the proven benefits of fasting in Robyn Openshaw’s new book, which you’ll get FREE with your Flash Fast when you order today.  

Here’s What You Get: 

  • 15 mini-meals shipped to you—5 each day, for 3 days—of our delicious, organic, plant-based, whole-food protein shakes, bars, and sprouted seeds (with the option to choose grass-fed bone broth protein for its gut-health benefits if you want).  
  • Access to a private Flash Fast community to support you and get answers to your questions—with knowledgeable and friendly health coaches who love to support you.
  • Special tips and tricks for how to maximize the benefits of modified fasting—(even how to eat more!)—without feeling hungry.

How To Do The Flash Fast—It’s Simple!

  1. Choose 3 consecutive days. 
  2. Choose an 8- to 12-hour window when you plan to eat the daily menus. 
  3. Eat only the items on the daily menu. 
  4. Fast for 12 to 16 hours between each daily menu. 
  5. Consume at least 2 quarts of water daily. 

The Flash Fast Daily Menu—It’s Yummy, Nutritious, & Mix-n-Match! 

During your 8-to-12-hour eating window, you can eat the items on the menu in any order, singly or in any combination.

You can eat the mini-meals in regular timed intervals, or another way that better fits your day. It’s up to you! Just stick to your eating window and the daily menu.

The daily menu is designed for an effective modified fast, with the nutrients you need for stable mood, cognitive function, and cellular energy and repair. 

Your taste buds will love the menus, too!

High-Quality Protein

(4 per day)

Our Plant Proteins give you plant-based protein, fiber, superfoods, and supplemental vitamins from whole-food, detoxifying ingredients. Or choose our clean and delicious Grass Fed Bone Broth Protein for the skin and gut health benefits. Stir, shake, or blend with 8-10 oz of water. Try them as a smoothie with water, a couple of ice cubes, half a packet of sprouted flax, and half a banana.

Organic Sprouted Flax

(1 per day)

Increases satiety and provides heart- and brain-protective essential fatty acids, as well as fiber, digestive enzymes, vitamins, and minerals. You’ll enjoy it best mixed with one of your protein packets, or in a smoothie blended with protein and your optional fruit or veggies. Try splitting it between two or more protein shakes a day to add a nutty flavor to your vanilla and chocolate shakes.


(1 per day)

Gives you additional healthy fats from nuts, with your greens, veggies and fruits. Bring it along when you’re on the go!

Fruit or Veggies


Because research shows that a modified fast should stay under 800 calories per day and the provided menu items are only 650 calories, you may add daily:

1 serving of fruit (apple, banana, peach, cup of berries, etc.).


2 servings (2 cups) of any cooked or raw vegetables (no added oil or salt, herbs are fine)


How the Early Bird Flash Fast Works

We’ll give you a fantastic deal and ship to you immediately. We’d love it if you fill out a questionnaire at the end of your fast and tell us about your experience.

For this special purchase, we have 50 Early Bird kits of each version of the Flash Fast available—a vegan kit and a bone broth kit. You can get additional kits only if your family member would like to be an Early Bird Flash Faster as well.


We’re especially interested in Early Bird Flash Fasters who are willing to participate in the private Facebook group, complete the Flash Fast by August 10th, and give us feedback on their experience. 

It’s Only 3 Days, for $29.95 (the Price will be $59.95 in August)—So Join Us for the Flash Fast Today & See What Results YOU Get... 


Frequently Asked Questions

Q: What’s the difference between a detox and a fast?

A: Fasting generally means going without food. The Flash Fast is a modified fast, following what the published research shows you can eat and still achieve weight loss, disease prevention, and symptom reversal benefits. 

Many programs claim to be “detoxes,” but the legitimate ones leverage scientific knowledge about the organs and systems of elimination, to draw out chemical and physical toxins to purify the body. Fasting and the Flash Fast modified fast have strong detoxification benefits as well.

Q: Can I add food if I'm really hungry?

A: Yes, you can add cooked or raw vegetables to your daily diet. (You may wish to amplify your protein shakes with a handful of greens.)

Q: What if I don't want to lose weight?

A: You are likely to lose a pound (or 2 or 3), when you eat only 650 to 800 calories per day, for 3 days. However, there are gut-healing benefits, and people who are underweight no matter what they eat have significant gut dysbiosis. So, they tend, through fasting, modified fasting, or a quality detox, to do some important gut healing, and get to a healthy weight afterward.

Q: How do I  join the Facebook group?

A: After you've purchased your Early Bird Flash Fast, go back to the announcement post in your Detox OR 12 Steps Group, and COMMENT requesting to be added to the new Flash Fast Facebook Group! For 12 Steps go here & for Detox go here

Q: Who shouldn’t do the FF?

A: Stage IV cancer patients in cachexia or patients who are severely underweight should not do the FF. Pregnant women and mothers who are exclusively breastfeeding, or where breast milk is the primary source of calories, should not do any form of fasting. 

If you are medically fragile, have liver or kidney diseases, have an eating disorder, take medications, especially insulin for diabetes or hypertensive drugs, or if you are over 70, please consult your trusted physician before undertaking any major change in diet.
