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

Robyn Openshaw, the GreenSmoothieGirl, says:

“The clinical research on modified fasting is the most exciting health discovery of this century so far.”

A “modified fast” tricks your body into thinking you’re fasting. You consume a specific amount of food and nutrients. And you don’t have to go hungry or give up food altogether.

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 100 Flash Fasters reported AMAZING benefits: 

  • Losing 2 to 7 pounds
  • Reduced joint pain 
  • Improved digestion
  • Better sleep
  • More energy…
  • …all in only 3 days! 

    They LOVED the immediate results.

    Terri R. of Henefer, Utah told us:

    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.”

    You can learn all about the proven benefits of fasting in Robyn Openshaw’s new book, “How to Get the Health Benefits of Fasting—Without Going Hungry,” 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.  
    • 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 help you. (Bring a friend and Flash Fast together, for extra fun and accountability!)
    • Special tips and tricks for how to maximize the benefits of modified fasting—without feeling hungry.

      How To Do The Flash Fast—It’s Simple!

      1. Choose 3 days in a row. 
      2. Choose 8 to 12 hours when you’ll eat each day. 
      3. Eat only the items on the daily menu. 
      4. Fast for 12 to 16 hours between each daily menu. 
      5. Drink 6-8 glasses of water daily. 

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

      During the 8 to 12 hours when you plan to eat, you can enjoy the items on the menu in any order, on their own, or in any combination.

      You can eat the mini-meals in regular timed intervals, like every 2 hours, or another way that better fits your day and your hunger level. 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 and cognitive function, as well as 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. 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:

      Unlimited leafy greens (spinach, kale, chard, etc.)


      150 calories of fruits and vegetables. For instance:

      1 serving of fruit (apple, banana, peach, cup of berries, etc.). OR 2 servings (2 cups) of any cooked or raw vegetables (no potatoes or sweet potatoes).

      (No added oils or salt. Herbal, low-salt, no-chemical seasonings are fine.)
