Breakfast Smoothie for the Transitional Day Fast for the 17 Day Diet

The Breakfast Smoothie for the Transitional Day Fast for the 17 Day Diet is a great smoothie recipe to start off your day.

If you’re not familiar with the Transitional Day Fast for 17 Day Diet, it was an addition to the 17 Day Diet by Dr. Moreno in 2014 as part of the Breakthrough Edition.



Essentially, you’re using three smoothies in place of your meals for one day that help promote fat burning and weight loss.

The Breakfast Smoothie for the 17 Day Diet has bananas and pineapple

Breakfast Smoothie Ingredients

You’ll notice ingredients for these smoothies aren’t technically cycle 1 or cycle 2 approved. No worries!

The Transitional Day Fast has its own set of rules, and each ingredient has been carefully selected for a certain purpose.

Here’s a quick overview of what you’ll find in the breakfast smoothie.


One “star” ingredient is pineapple. 

Even though pineapple might be a Cycle 3 approved fruit, it’s used for the breakfast smoothie.

Pineapple has great nutritional qualities – it has Vitamin B promoting energy.

Energy is what you’ll need during the morning as you’re generally most active during this time and your body can burn off the energy from the smoothie ingredients pretty easily.

If you’re allergic to pineapple or don’t care for it, use another favorite food such as berries or an orange.

Pineapple is one of the star ingredients in the breakfast smoothie for the 17 Day Diet Transitional Day Fast


Another star ingredient in the Breakfast Smoothie for the 17 Day Diet is banana.

Bananas are full of vitamins and minerals. One important benefit is potassium.

In addition, bananas give your smoothies “bulk”, filled with fiber and keep you fuller longer.

Plus, if you use a greener banana, you can take advantage of the resistant starch found in green bananas that help promote weight loss. 

Bananas are another star ingredient in the breakfast smoothie for the 17 Day Diet

Substitutions for Certain Breakfast Smoothie Ingredients

It’s always best to make the smoothies as-is. The doctor formulated the smoothies with certain ingredients for a reason.

However, if you’re allergic to pineapple, for instance, swap it out for a low-sugar berry such as strawberries, blueberries or raspberries (or a combination of the three).

If you’re not a fan of banana, choose another fruit such as mango or peaches.

Whey Protein Powder for the 17 Day Diet Smoothies

The recipe calls for vanilla flavored whey protein.

The problem with this is that many, if not all, flavored protein powders will contain either sugar, artificial sweetener, or a combination of the two.

I highly recommend using a non-flavored whey protein. I use Jarrow’s unflavored whey protein.

Jarrow’s also offers a grass fed whey protein powder.

When you’re using an unflavored powder, you’re not only eating a cleaner processed food, but you’re also able to control the flavor of your smoothie.

Jarrows Unflavored Whey Protein is what I recommend for smoothies for the Transitional Day Fast for the 17 Day Diet

How to Freeze the Breakfast Smoothie for the 17 Day Diet

If you have time over the weekend before you start your Transitional Day Fast, you can easily make your breakfast smoothie ahead of time and freeze it when you’re ready to drink it.

Place your blended 17 Day Diet breakfast smoothie in a sealable freezer bag and lay it flat in the freezer so it freezes in a thin layer for easy storing and defrosting. 

When you’re ready to have your breakfast smoothie, take your frozen flat smoothie bag out of the freezer the night before and allow it to defrost in the refrigerator over night. 

This will not only save you time, but you’ll always have a super chilled breakfast smoothie ready to go when you need it! 

Plus, if you don’t have time to drink it at home, it’s a perfect grab-and-go in a bag type of meal.

Take your baggie of defrosted breakfast smoothie with you and put it in a glass when you get to your destination or drink it on the way to work.

Other Transitional Day Fast Smoothie Recipes for the 17 Day Diet

You can also find the other two recipes for lunch and dinner that are a part of the Transitional Day Fast:

What Cycle is this Breakfast Smoothie Approved For?

As I mention above, this breakfast smoothie is part of the Transitional Day Fast when you drink three smoothies a day (breakfast, lunch and dinner).

The Transitional Day Fast can be used in between each cycle or when you have a bad few days and want to jump back onto the diet and need a quick boost in weight loss. 

If you decide to drink this breakfast smoothie outside of a Transitional Day Fast, then it would be appropriate for Cycle 3.

Breakfast Smoothie for the 17 Day Diet

Prep Time: 5 minutes
Cook Time: 5 minutes
Total Time: 10 minutes

This is a great fat-burning breakfast smoothie designed to give you energy when you might need it the most!


  • 1 cup unsweetened almond milk

  • 1/2 cup plain low-fat yogurt

  • 1 scoop vanilla whey protein powder

  • 1 serving powdered fiber

  • 1/2 cup crush pineapple, canned in its own juice, drained
1/2 frozen banana


  1. Place the ingredients in a blender, and blend until smooth.


Approved for the Transitional Day Fast for any cycle, otherwise approved for only Cycle 3.

Tip from Book: Blend the ingredients for several minutes as this will add air to the smoothie and the extra air will make you feel fuller.

Torey’s Tip: Add crushed ice to your ingredient list and blend. The ice will make the smoothie slushy and add a bit more volume to your meal.

    • Smoothies are a new addition to the diet this year. Technically, they are to be used in between cycles or during a time when you fall off the wagon. The smoothies call for whey protein powder, so if this is your idea of a protein shake, enjoy!

    • Jennifer, the book doesn’t provide caloric intake. Actually, the 17 Day Diet is not about calorie counting, so you really won’t see much about calories in the book.

        • For the special transitional day fast, this is the exact recipe and there’s probably a reason the doctor included yogurt. This is quite common, but not everyone likes yogurt in their smoothie. I think it’s a matter of preference.

          • My suggestion is to find your favorite fruits and veggies that are all C1 approved and experiment! I might be posting smoothie recipes at a later time, so stay tuned!

    • I sometimes make a smoothie for breakfast during cycle 1 because I get tired of eggs (not to mention allergic to them). I use Kefir (plain and unsweetened), frozen berries, crushed ice, a little water (so it will blend better) and maybe some spinach. You can add Truvia but I try to avoid artificial sweeteners. All of these ingredients are ok on cycle 1.

    • Lisa, there isn’t, but you can combine your greek yogurt, your favorite low-sugar berries a little bit of liquid (cold water) to make a perfect smoothie!

  1. would I be able to use an organic vegetable protein that is gluten/gmo free no soy or dairy and is cholesterol free?

  2. Thank you so much for your tips and recipes? I’m wondering if I’m allowed to eat soup on the diet if made from allowed ingredients? Thank you!

  3. I’ve made the breakfast smoothie and the lunch smoothie and I couldn’t finish drinking all of it. It was way too much for me to drink and I couldn’t finish them. Can I half the recipe or do I have to drink all of what it makes.

    • Hi Janet! Everyone requires different amount of calories for the day. Rather than making half the recipe, you may want to first try drinking as much as you can of each and maybe use leftovers as snacks in between each shake in the event you get hungry.
