What You'll Learn

The Transitional Day Fast
The smoothies for the Transitional Day Fast are formulated by doctors to provide optimal results. The breakfast smoothie typically contains the most sugar out of the three daily smoothies, as you are generally more active in the morning and early afternoon. This smoothie usually includes pineapple and banana, with the option to substitute other fruits such as berries or an orange if you have allergies or preferences. Banana adds vitamins, minerals, and potassium, as well as bulk from its fibre content, keeping you fuller for longer.
The lunch smoothie is a community favourite, combining low-sugar strawberries with unsweetened almond milk and added fibre to promote satiety. It also includes plain yogurt and extra protein. The dinner smoothie is a "green" smoothie, packed with spinach, blueberries, matcha powder, and unsweetened almond milk. Spinach is an excellent source of fibre, minerals, and vitamins, and it blends well with ripe fruit, making it barely noticeable in taste. Blueberries are a superfood, packed with antioxidants and lower in sugar than most fruits.
You can make your smoothies ahead of time and freeze them in sealable bags, taking them out the night before and allowing them to defrost in the refrigerator. This is a convenient option if you work during the week. Remember to blend your greens and liquid very well before adding your fruit to ensure a smooth consistency.
In addition to the three smoothies, you are encouraged to drink eight 8-ounce glasses of water and 3-4 cups of green tea throughout the day during the Transitional Day Fast.

Breakfast smoothie recipe
The 17 Day Diet is a diet plan created and authored by Dr. Moreno. Back in 2014, he updated the diet in his published book, 'The 17 Day Diet Breakthrough Edition'. One of the major changes is the optional Transitional Fast Day, also known as the "smoothie day". On this day, you replace your regular three meals with three smoothies.
The breakfast smoothie is a great smoothie recipe to start your day. It is a tropical blend of pineapple and banana. Some other ingredients include yogurt, unsweetened almond milk, and protein powder. Banana is a key ingredient as it is full of vitamins and minerals, especially potassium. It also gives your smoothie "bulk", keeping you fuller for longer. If you want to use a different fruit, mango or peaches are good alternatives.
If you are allergic to pineapple, you can swap it out for a low-sugar berry such as strawberries, blueberries, or raspberries, or a combination of the three. It is recommended to use an unflavored protein powder as flavored powders often contain sugar or artificial sweeteners. You can also make your smoothie ahead of time and freeze it.
- Pineapple
- Banana
- Yogurt
- Unsweetened almond milk
- Unflavored protein powder
Place the ingredients in a blender and blend until smooth. You can also add crushed ice to make the smoothie slushier and add volume to your meal.

Dinner smoothie recipe
The 17 Day Diet is a diet plan created and authored by Dr. Moreno. In 2014, Dr. Moreno updated the diet to include an optional Transitional Day Fast, also known as the "smoothie day". On this day, dieters replace their three meals with smoothies; specifically, fat-burning smoothies.

Spinach is a great source of fibre, minerals, and vitamins, and it can barely be tasted when blended with ripe fruit. Blueberries are lower in sugar than most fruits and are packed with antioxidants.

If you want to make this smoothie outside of the Transitional Day Fast, it is appropriate for Cycle 3 of the 17 Day Diet.
