This 5 Day Smoothie Fast cleanses the body gently using fresh fruits and vegetables for five days, never making the same smoothie recipe twice! You can also add a boost of protein to the smoothies with these helpful tips.
Have you ever been interested in doing a smoothie fast, but it seems too daunting? I know I have felt that way. The thought of not eating solid foods for a few days seemed a bit too extreme!
But I learned that doing a smoothie fast had many benefits for your body, and I wanted to give my gut a short term rest from solid foods. So I came up with a plan that is achievable and simple!
I created a plan that is both challenging (not too easy) AND within reach so you are able to succeed.
Whether it is resting your gut from solid foods or lowering your calorie intake, a smoothie fast can have great benefits!
Why do a smoothie fast? Consider the health benefits
Knowing your motive and recognizing your health goals are important when considering a fast. Personally, I am in fairly good health with no major chronic issues. My cholesterol and blood pressure are well within normal ranges. I try to eat healthy food regularly. In my opinion, I don’t need to fast.
But when my husband fasts I feel compelled to support him in his efforts. After all, I don’t think I’d be so thrilled to see the rest of my family eating big bowls of spaghetti while the smell of freshly baked bread lingered in the air either.
The truth is I can benefit from fewer calories and less solid foods (as we all can), but not eating entirely simply does not work for me in this season of life.
How to Plan for a Successful Smoothie Fast
Fasts are not easy, at least for me! More than half of the battle is mental. If you pick a fast that doesn’t fit with your current state of health and frame of mind, you’re only setting yourself up for failure.
That’s why I’ve come up with a list of things to consider when choosing a fast:
- Willpower. In my case, choosing not to eat anything would be setting myself up for failure. I do, however, have the willpower to refrain from eating certain types of food.
- Responsibilities. I have a husband and two children to care for, plus a homestead and a job to manage, and there are always various social commitments. Life does not slow down so I can sit alone for several days, so water fasting isn’t the best option for me just yet.
- Type of fast. There are many types of fasts (water fast, intermittent fasting, etc.), but I prefer a smoothie fast. It is food, yet not solid. It is difficult to consume only liquids, but attainable.
If you’re not following a specific plan, you must create your own
Usually, I have a green smoothie every day for breakfast, which is my favorite go-to recipe (it is seriously delicious, even with leafy greens). I incorporated smoothies into my long term daily routine because I wanted to be intentional about my health. In my mind having one more smoothie for dinner isn’t that difficult. However, my normal green monster smoothie uses kefir and I want to keep my food intake as easy to digest as possible.
I created the following “rules,” just so the fast has some structure:
- Five full days
- Two smoothies per day
- One serving (one cup) of kefir per day
- Raw fruits and vegetables only (with two small exceptions, see days 2, 4 and 5. Frozen fruits are okay to use)
- No duplicating fruit/vegetables on the same day (except for the bananas)
- No grains, meat, seeds or nuts
- No sweetener
Why fast for five days?
Five days may seem like an odd number, but there is a method to my madness!
Food takes an average of 36-72 hours to run the entire course of digestion, from intake to exit. In order to allow my digestive system minimal rest, the fast needs to be at least three days. Three days didn’t seem very difficult, and ten seemed a bit extreme. I settled on five days for two main reasons:
- Digestive Rest. It allows two full days of maximum digestive rest within the constraints of my fast.
- Success. I really want to succeed, and I don’t think I’d make it much longer than 5 days!

I recommend using a high powered blender for making smoothies. I love my Blendtec!
Fasts don’t have to be extreme to be beneficial
The smoothie route is perfect for those fasting for the first time. It is just the right balance of challenge and accomplishment. Each day has enough variety to keep it from being boring while still following the rules of the fast.
It feels great to make it through the full five days! The first time I did a smoothie fast I thought I’d be run down and exhausted, worn out from the lack of food, but that wasn’t the case at all. My energy levels felt higher and it was great to know that my body was getting pure nutrition without any weird additives. The benefits throughout the rest of my body were noticeable too!
- Great sleep.
- I didn’t crave any particular foods, including grains and sweets.
- I felt more satisfied after eating.
- My gut felt rested.
- My skin was clearer.
Of course, after fasting, it is normal to be eager to eat food again. Personally, when I complete a fast it makes me look forward to the next one. I get to know what my body is capable of and I know what to expect!
FAQs For Smoothie Fasting for 5 Days
How many calories per day do you consume in a smoothie fast?
The daily calorie intake ranges from 630 to 690 – well below what our bodies require to operate on a daily basis. Limiting calories and consuming only blended fruits and vegetables allows your body to rest from the constant work of breaking down food.
Is smoothie fasting healthy?
Short term smoothie fasting, like this 5 day smoothie fast, has been very beneficial for my health. I don’t smoothie fast for longer than 5 days due to my busy lifestyle, AND I like to eat healthy food too much!

Do you have a good suggestion on what I can sub for coconut water since I’m allergic to coconut?
Karen @ Team Crumbs
Hi Maria!
You could always try a little bit of orange juice, or just water would work too. Hope this helps!
Phillip
Which of these recipes would it be okay for me to add ground Turmeric? I think that’s the only thing missing out of this list. Anyways, I’m starting tomorrow, Monday April 25th, 2022!!
Julie
Hey Tiffany,
With the fasting, is it allowed to eat light for lunch/snack.
SJ - Team Crumbs
Hi Julie,
One of the purposes of a smoothie fast is to give your digestion a break by not snacking and by only consuming liquids. Talk with your doctor and pick the type of fast that will work best for you!
Katie
Do you drink coffee, tea, or other beverages on this fast, or stick with water? With summer coming up I am all about the cold brew and I don’t add anything, like sweeteners or dairy.
Also, I am trying to go totally plant based. What would you suggest instead of using kefir?
Thanks!
Tiffany
Hi Katie! On a smoothie fast, I allow myself all non-alcoholic beverages (except juice, which is just too sweet for me). I’d sub non-dairy yogurt or just non-dairy milk instead of kefir. It’s not vital!
Lia
I feel silly asking this, but do you peel the orange and lemon or blend the whole thing, rind and all? I have a Vitamix and it can handle just about anything. Thank you!
Tiffany
I’d recommend peeling citrus, since the peel can be bitter. 🙂
ben
today is day 46, I am juice fasting now. i lose my weight of 17.8%. next time i change to smoothie fasting, but i believe it ‘s safer and slower than juice fast.
Savannah
Hi! Do you use ice as well or just the ingredients?
Connie
From your rules: No duplicating fruit/vegetables on the same day
But if following the smoothie recipes you posted, there is a minimum of 1 banana in each morning smoothie and each evening smoothie.
Should your rule be prefaced with “With the exception of bananas…”
Karen @ Team Crumbs
Hi Connie!
Thanks for your thoughts. We’ll add that for clarity..:)
Libby
Instead of the kefir can I use vegan yoghurt?
Tiffany
Absolutely!
Kelley
I’m not able to have dairy. Can I use water kefir grains instead?
Tiffany
Sure!
Velma
What is the water intake for the 5 days on this SmoothFast?
Tiffany
As much as you need, Velma!
Dessy
Hi Tiffany !!
Just found your 5 day Smoothie Fast & I’m really excited to try it !!
What do you do for lunch & snacks during the fast ?
Will the 2 smoothies a day hold you ?
Is there a Shopping List section for the fast ?
Thanks,
Dessy
Tiffany
Hi Dessy! We don’t have a shopping list for this fast, since it’s more of a pick-what-you-want type of thing. I didn’t have set meals during the fast either. I made a smoothie twice a day and kept it at that. I was a little hungry early on, but that went away around day 3.
Julie
I cannot have citrus. Is it okay to just use other fruits I have on hand?
Tiffany
Yes!
