This cleanse is for you if…
I get it — “cleanse” can sound like three weeks of sacrifice for who-knows-what. So let’s be clear about the goal: flood your body with nutrients, give your gut a real break, and hand your energy back to you.
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.

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.
We offer a 7-day money back guarantee. Enroll now and get 7 days to go through the Week 1 Nutrition Plan, share it with your doctor, try a recipe or three, and say hello to your fellow cleansers in the private support group. 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 really had a good time doing this. It was fun following the support group with such amazing people going through the same thing I was. I wasn’t completely on track with everything, my schedule is crazy busy. I’m so glad I participated, Jen made this an amazing experience. I would like to continue my journey with you all. God Bless.
2022 resolutions stuttered to a halt as my family came down one by one to a cold, followed in quick succession by Covid – we ate and drank what we wanted just to get through the day. This cleanse was just the the cleanse needed.
This cleanse is incredibly easy to follow with all the recipes and shopping list provided. The food is delicious and filling. The prep can be a little intimidating if you don’t normally cook a lot, but it’s totally worth it.
I’m glad that I spontaneously took the plunge and signed up! Despite being on vacation in an unfamiliar house and having a lot going on family wise especially with a pending divorce it felt good to do something so positive for myself. Since I wasn’t home I had to buy everything on the shopping list which was initially expensive and very time consuming because I was in an unfamiliar area. However it was certainly a good value not only as an investment in my health but also financially as I would have spent a lot more with just a few meals out. The unexpected bonus was that my fast food loving 23 year old son who quickly turned down my invitation to join me was at least open enough to trying a well presented sample of my warm kale salad. He said that was “not actually bad”:) I immediately jumped to the taco salad showed him the picture and asked if he would try it for dinner. He agreed! We both devoured it and wished there was more. Next I made double of the coconut cauliflower rice dinner. He asked for seconds! He really liked the berry bowl crush too. I know have several healthy recipes we both enjoy which is wonderful. I was very satisfied with everything learned a lot (including that cauliflower in a smoothly was ok when had right away) and never felt hungry. In fact I didn’t even get to snacks most days. I do wish I’d noticed the grocery list in my inbox Friday and gotten a head start shopping (especially to let avocados pears and bananas ripen). This is my first experience with Simple Green Smoothies and I wholeheartedly recommend it. And get the book. Flipping back and forth in it was easier than pdf.
Realized I was eating very few fruits and vegetables so tried the winter cleanse. Everything was really tasty and after a week I felt much better! Looking forward to incorporating plant-based into my diet going forward. Thanks so much for making this available!!!
I did the autumn Fresh Start three-week program and loved it. This winter the cleanse came at the perfect time. Great recipes. I honestly wish that Simple Green Smoothies would come out with their own meal service:D
This cleanse was awesome! I loved the hard copy book that I got for free as part of the cleanse. The recipes were easy to make and delicious. The dinners especially were great and I hope to add some to my weekly rotation. I would recommend joining this cleanse! I hope to join the other seasonal cleanses as well, based on my positive experience with this one. If you’re thinking about it, give it a try!
It was filling and delicious, thank you for the support. I will make the rest of the recipes that I missed this week when I am on vacation.
Take the time to free yourself from the food that binds you! You may complete a perfect cleanse and you may not, but steps in a nourishing direction will teach you so much. You are ever and always worth effort! Do not give up!
The recipes are wonderfully easy to complete Try to do your prep the day before so you will be ready to go. Recipes are great and beautiful as you can see. The RAWK the Year program and coaching is encouraging and uplifting from the very beginning. Keep up the pace with the cleanse and you will be rewarded. Happy Cleanse Got to try this Apple Crisp with Cashew Cream —– MMMMMMMM
So grateful for the guidance and inspiration provided by Jen and the admins. I needed this right now all of it! This is so much more than a “diet” or even a health plan. It’s a way of life. I’m sleeping better feeling better and hey I’ve dropped 5 lbs. without ever once feeling deprived. Loved the amazing recipes. Many will be in permanent rotation. I’m a Grandmother to 3 amazing boys ages 5 and under. My purpose is to remain strong and healthy so that I can continue to take an active role in their lives for many years to come. Thank you for this holistic body/mind connection and for the energy and love you have put into this program. I hope to continue the journey and bring my husband along with me. Margo Smith
I purchased the hardcopy Winter Cleanse book and found it structured and helpful to read and not be on the computer screen. A great reference and everything is well sequenced in the book, to match the daily emails. I am not on social media, so did miss out on that support group. The recipes are delicious! Thank you, Jen, for being the muse to inspire and concentrate on health and cooking.
I enjoyed this cleanse and am looking forward to more. The meals were tasty and used some ingredients that were new to me like fennel. I’m always amazed by how filling veggies can be! I also found it easy to modify for my schedule and our (my husband’s) taste preferences. Thank you!
Wow what a life changing experience. The Winter Cleanse gave our family the opportunity to learn try and implement new plant-based recipes which is one of our long term goals! Although many of the meals were sweet majority of them were super delicious especially the Warm Kale Salad Spiralized Vegan Taco Salad and all the smoothies. We are not huge sweet eaters so some of the recipes we switched certain ingredients to make them more umami salty and savory. One recommendation I will share is REMEMBER TO DRINK WATER!!! This cleanse you have to drink your breakfast AND lunch (which was difficult for us) so you feel like you are drinking constantly so sometimes (for us most of the time at first) you forget about water! Overall this was a wonderful experience and the best part of it all is the FB COMMUNITY!!! From the SGS admin to all the individuals participating in the cleanse the amount of support honesty sharing and lol emoji’s are AMAZING!!! I would definitely recommend this cleanse!
This cleanse was great. I was really looking forward to it and it did not disappoint. The food was delicious and the support was super. Jen was really on her game.
