This cleanse is for you if…

You’re running on empty
Natural energy is closer than you think.
Your cravings are in control
Skip the sugar spiral and the 3pm caffeine crash.
Your gut’s been through it
Bloat, heaviness, the whole uncomfortable mess.
Feeling foggy or just off
Clearer head. Steadier mood.
Chronic aches & inflammation
Calm the fire with food that heals.
Struggling with skin issues
Glow’s around the corner.

Carrie EichensHow the cleanse works
Plant-based whole foods packed with vitamins, minerals, and fiber to feed your body, support your gut, and help your liver, colon, and kidneys do their job the way they’re meant to.
Week 1
Clean the plate
Step back from the Top 8 inflammatory foods (alcohol, meat, dairy, gluten, added sugar, and friends) and eat foods that energize and heal.
Sample recipes: Tropical Detox Smoothie, Power Trail Mix, Hearty Chard Skillet and Greek Salad
Week 2
Detox with love
Ease off legumes and grains while you load up on liver-loving, fiber-rich foods, so you feel lighter and clearer by the day.
Sample recipes: Strawberry Lemon Chia Pudding, Broccoli Potato Soup and Lemon Pepper Zoodles
Week 3
Rawk the lifestyle
The part the powder cleanses skip: ease grains and legumes back in and move into a way of eating you can actually keep.
Sample recipes: Strawberry Banana Smoothie, Herbalicious Hummus and Veggie Quinoa Pizza

Why this cleanse is different
When the box runs out, so do your results. My cleanse works the opposite way.

| What you learn | How to cook plant-based, for life | Nothing |
| When it ends | Your skills and results stay | Results fade; buy another box |

Grad stories
I'm sleeping better, I'm happier and have more energy.
I've been walking every day with my dog or by myself with a book and doing strength training, which feels great. I've lost 7 pounds and have a better outlook because I don't have as much inflammation and fatigue.
Grad stories
It has recruited my husband (big win).
I'm not a natural cook and it takes a lot of my energy to plan and prep… BUT when I prep several meals and have healthy options at the ready it feels so nice. Did I complete this cleanse? Heck no! It fell in a month where we had multiple kids home sick, snow days, and a trip. HOWEVER…
Grad stories
I feel like the best version of myself.
I got so many compliments about how I looked… not just about the weight-loss but about glowing skin. I feel like the best version of myself when I'm eating plant-based… and have this 21-day cleanse to thank for that!
Grad stories
I wish I had known about this in my 40's.
I am 69, and I can honestly say adopting this lifestyle would have saved years of misery and expense due to medical issues.
Grad stories
I've been changed for the better.
Now, I know what foods make me feel great and give me tons of energy. It's like I was a caterpillar that emerged from its cocoon and turned into a beautiful butterfly. I'm not looking back.
A note from Jen
If you’re on the fence, I was too
Would the recipes actually be good? Would I just bounce right back to my old habits? Was it worth eating 100% plant-based for three weeks? Then about eight days in, I was hooked. Less bloated. Sleeping like a rock. Energy through the roof.
Most cleanses end and leave you exactly where you started — or worse, hooked on a product you have to rebuy. This one is different on purpose: you learn to cook real food, so you walk away with skills that don’t run out when the box is empty.
And if you’re nervous about the food? Remember — this is literally what I do. I make plant-based food that’s so good you forget it’s “healthy.” Because healthy should be tasty.

Not likely. The recipe portions are deliberately generous to accommodate even the largest appetites. This is not a starvation diet, it is a celebration of food, flavor, and abundance. We are not counting calories. You will be eating three to five times each day (breakfast, mid-morning snack, lunch, afternoon snack, and dinner, if you choose to.) This cleanse is not designed to starve you, and you’re not limited in the number of times you eat, or the amount you eat – only in what you eat. If you do get hunger pangs, make sure that you’re really hungry, and not just bored or thirsty. If it’s a case of real hunger, go for one of the bonus snack recipes, a piece of fruit, or a small handful of nuts, or seeds. One tip to avoid hunger is to chew your green smoothie. This may sound silly, but the chewing action signals your body that food is on the way, and triggers the digestive processes.
Nope — and that’s the whole point. This cleanse runs entirely on real food you buy at your regular grocery store. No proprietary box, no capsules, no subscription. You’ll learn to cook with whole ingredients so your results actually last once the 21 days are up.
You may have many of the staple ingredients in your kitchen already (avocado oil, raw cashews, maple syrup, ground cumin, nutritional yeast, coconut oil, etc). If you do not, the first shop typically costs about $150. Then, once your kitchen is set up, we estimate the cost of the produce to be between $100 per week. If you choose to supplement the plant-based recipes with high quality animal protein like organic chicken breast or cage free eggs, your grocery bill will be higher.
And remember — you’re buying real groceries, not a $400+ box of powders you’ll run out of. Most of this is food you’d be shopping for anyway, just put to much better use.
If you struggle with getting quality sleep, we advise omitting coffee throughout the cleanse. You will get the best results and many cleanse grads choose to stay off coffee after the cleanse because they feel so great. If you and coffee aren’t ready to break up, we suggest having just one cup in the morning to support quality rest and sleep.
If you want the full benefit of cleansing your body, stick with the plan as close as possible. Our detox meals are crafted by our holistic nutritionist for optimal cleansing. This is not a vacation, it’s a cleanse. Yet of course if you truly cannot stand cilantro, turmeric or fennel, you can substitute them out for something you do enjoy, or choose another meal.
Of course— life must go on! The 21-Day Cleanse is a flexible program that you can follow while living your life with family and friends. Using the weekly meal plans and recipes will help you get great results. But, you can still get good results by sticking to the recommended foods lists. You can eat “off meal plan”, eat out, and travel during the program— feel free to ask for tips inside the community to help you the most.
You may experience short-term symptoms like: headaches, bloating, muscle cramps, skin irritations, fatigue, irritability, mood swings, or change in bowel frequency. These symptoms are completely normal and expected.
It usually takes between 2-5 days to complete the withdrawal phase of the 21-Day Cleanse, yet it’s absolutely worth it. Giving your body a break from stimulants will allow your organs to heal and your body to recharge fully. Remember, these symptoms are proof that the cleanse is working and your body is getting the care it needs.
You’ll definitely spend more time in the kitchen throughout the cleanse. In some ways, this is like a crash course plant-based cooking school. I highly suggest following our prep guide to make most of the smoothies, snacks and meals over the weekend. Breakfast is a smoothie (10 minutes), lunch is a reheated soup or quick salad (15 minutes) and dinners will range from 15 minutes – 1 hour to prepare. The good news is, the dinners repeat so you make once and reheat for another evening to give you a break in the kitchen.
We know all about busy schedules here, which is why we’ve provided a weekend prep guide that saves you tons of time during the week. If you’re working and have a full schedule, expect to spend 3-4 hours shopping and prepping on the weekends to make each cleanse week stress-free and enjoyable. The cleanse gives you a wonderful opportunity to really listen to your body. It’s an individual experience that differs for everyone. Depending on the level of toxicity in your body, there may be some less- than-amazing symptoms in the first 3–5 days, such as headaches, nausea, fatigue, skin irritations, etc. Once you hit day five, these should only be distant memories, and you’ll be well on your way to greatness. But some people sail through the entire cleansing period with no side effects at all. You may feel amazing throughout the entire cleanse, or your energy may wax and wane a little.
This cleanse is great for most people, yet you should avoid cleansing in the following situations: advanced cancer, under 16 years of age, if you have an eating disorder, kidney or liver disease, and if you’re underweight. If you have a blood sugar regulation issue (diabetes, hyperglycemia, hypoglycemia) or any other medical condition, you should seek your doctor’s advice before undertaking a cleanse. If you’re pregnant or breastfeeding, you can absolutely do the cleanse with some modifications. If this is you, let us know and we can give you specific tweaks to the program to make sure you’re benefitting your baby and body.
You may find that you have more energy than normal—and more motivation! Why waste it? Get moving! Be mindful that you may need to take it down a notch though as your body adjust to the new way of eating. If you normally exercise fairly intensely, reduce your output until you feel strong and energized.
If you don’t normally work out, you would do well to include some regular walking, yoga, swimming or gardening during this time. Try to sneak in some incidental exercise, such as getting off the train or bus one or two stops early and walking the rest of the way. Or park further away from the entrance to the grocery store and walk.
Absolutely. My husband loves our cleanses — the clear plans, the tasty recipes, and how good he feels by the end. Just double the grocery list and recipes so there’s enough for you both.

If you decide it’s not for you, send us an email within 7 days of purchase and I’ll refund you. I’m that confident that when you commit to this cleanse, you’ll see results… and keep them going. You have nothing to lose but so much to gain when you go plant-based for 21 days.
Reviews
What grads say after 21 days of real food.
I joined because I have not been at my ideal weight since I had kids. I have known the health benefits of smoothies healthy meals detoxing for a long time and have incorporated this into my lifestyle as much as possible but lately in my forties I can just look at a cookie and gain weight. So long story short the timing was right so I didn’t think twice about it. While going through the program I really appreciated that I didn’t have to figure out what to eat on my own it was all done for me. Saved me a bunch of time. I felt great after the cleanse. I lost a little weight in just 7 days and felt well rested. I’m proud that I’ve always been willing to try something new. A willing spirit has led me to this moment and I don’t think I’m going to regret it.
Take Jen’s healthy recipes with you while traveling.
We travel in an RV and often are without cell/wifi for days. I love having these printed books to take with me to keep healthy choices with us on the road. As we age into our 60’s & 70’s we want to make healthy food choices so we can do the traveling we want to do. Love Jen and her healthy advice.
Eating heallthier
The printed Autumn Cleanse cookbook is excellent. It is beautifully illustrated and well organized and I love the recipes. Since I received it, it is constantly in use. Its contents are certainly a staple in my household . I loved it so much that I purchased other Simple Smoothie cookbooks too.
Autumn Cleanse (Mind & Body Reset!)
Super happy with the Autumn Cleanse book! The book is beautifully designed and illustrated! The layout and format of the cleanse guides and recipes are well-organized, easy to read and follow. The book provides comprehensive and informative narrative on the benefits of a cleanse as part of a healthy lifestyle and is easy to reference within the book. Highly recommend!
Very Easy to follow
I was very happy that recipes were so easy to follow and they were delicious .I have lost 8 pounds and i have so much hair on my head it’s unbelievable. Its a good start for me to make the changes in my eating habits . I am still making the recipes from the cleanse ,best part is my husband enjoys everything from the cleanse. I am so glad I made the decision to join the cleanse. Cant wait for the next one. Thank you SGS .
Supported journey
This is a great way to make significant change and have a great support system around you. Highly recommended to join love for this experience.
Refresh-reset
I started the autumn cleanse with the intention of resetting my eating habits. I really enjoyed most of the recipes- I couldnt believe I made food that tasted that GOOD! the potato soup- incredible the tomato soup- lickin’ the bowl clean!! I didnt need as much variety as the plan provided so I pared it down to suit me. It was easy to stick to the meal plan everything was laid out. I felt really great during the 21 days no fatigue or headaches- possibly because I am not a caffeine person. The only bummer was that I did not lose any weight. I was really hoping for that. Having a calorie count would have been helpful- and I did not have the time to do all the calculations thus why I chose a meal plan program. When I requested a calorie count the response I got was to buy another book ( that has the calories in it). might consider it. Thanks for the program. I will now be continuing the plan- to use up all the remaining ingredients.
Temperance
I am amazed at how easy and delicious the meals have been. I had two family birthdays and then had to visit family in Texas right in the middle of the cleanse. Normally I would have been tempted to cheat and snack on gods offered. But I had begun feeling so good, that I couldn’t bear to mess up the good things going on with my body. So I packed my dried goods and shopped for fresh veggies and treated my mom and sister to the meals- they loved it as well! This has been an experience that enabled me to shake a habit of nervous eating and stress eating and has enabled be to grow in virtue at the same time. It is very freeing to say no in order to say a better “yes” I am grateful and look forward to the things I will be able to do with the extra energy and clarity.
Bravo.. I’m now a graduate of the 21 day cleanse
I found the whole 21 day experience to be an interesting learning experience. The plan was well organized and easy to follow and the food was very enjoyable. I found the second week a bit tough but I stuck with it. Even my partner, who is very set in his ways, ate more and more of it as time went by. We both agree it’s the way to eat and will continue along this path. I purchased your cook book and am already planning the weeks meals. Thank you for creating such a great introduction to a healthier way of eating.
Finally Found You
I have been a vegetarian for my whole life and struggled with how to mix and blend the meals to taste good and keep me satisfied. Well, this is the plan that did it for me. I loved the recipes the combinations and flexibility. I never was able to keep my afternoon hunger under control and know I know what works for me. I enjoyed the conversation on the website and was able to get answers and even answer a few. Thanks to Jen and her team for all the support and encouragement.
Wonderful and Healthy Deliciousness
This three week cleanse was a great segway into eating a healthier lifestyle again. I feel lighter, happier and with more energy. My only critique is that sometimes the recipes were very…boring…. They, for whatever reason, did not sound very exciting to make or eat. However I powered through and can’t wait to look through the recipes on the website! Thank you!
Delicious Recipes!!
I really loved all the recipes of the cleanse. I’m a picky eater and liked about 90% of the meals plus all the ingredients (really except beets and shredded coconut). So that’s a win! The cleanse is definitely challenging mostly because the amount of time you need to spend to cook everything. I tend to like simple snacks and meals. But I’m happy to add so many really flavorful recipes to my repertoire.
Such an awesome experience
My daughter and I did this challenge together. We did it because she was having major digestional issues. We thought it would be a good way to start an elimination diet and try to kick our sugar and caffeine habits. I was not sure about doing only plant-based foods. Wow I am hooked. The recipes provided for this cleanse were incredible! I will continue to use them and I’m planning to stick with this routine when I am cooking at home. Obviously I may break it if we go out to dinner or am on a trip. By the third week I felt a lot of energy and was sleeping better. I am excited to do the other seasonal cleanses when they become available.
Feeling Grateful
The Autumn Cleanse was a huge success for me. I was able to stick with the plan for the entire three weeks, and I am feeling great. I never thought I could do without my morning coffee or topping everything with cheese, but it was so easy with this program. The recipes were delicious, and I think taking a day to meal plan is something I will continue to do going forward. I will definitely consider doing another cleanse in the future, and am very grateful for committing to this one and indulging in a lot of self care and healing.
Not Exactly Easy
The shopping & the prep were extremely time consuming… Recipes were clear, but again time intensive… A lot ot eat…
