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.

What grads say after 21 days of real food.
The 21-Day Spring Cleanse is SO much more than a cleanse! I learned how to make simple plant based meals taste out of this world while giving my body delicious nutritious and colorful meals that I could happily serve at any dinner party with glee! The benefit of the private Support group cannot be overstated – folks from around the world shared their tips tricks and best kitchen equipment recommendations and were at times encouraging and very often we were celebrating our successes with pics of these yummy “keeper” recipes! The best part is that I am truly on the path I’ve always wanted to be on but didn’t have enough structure or support to pull it off as a lifestyle. Now I can just keep going! I am recommending this 21-Day Cleanse to everyone! Thank you to Simple Green Smoothie and to everyone who participated and made it possible! Jen you’re a real RawkStar!
I wasn’t sure about this cleanse but it was awesome! The recipes are delicious and fairly easy, so I could see adding my favorites to my regular meal rotation. I lost weight which was a huge win for me! It also helped me realize I need an afternoon snack to keep from not overeating at night. It’s a lot of work to shop and prep each week, but overall it felt worth it. Highly recommend! Thanks SGS team!! 🙂
I always said I could be a vegetarian but never a vegan, let alone cut back sugar and wheat as well. The recipes were so delicious I was really surprised. While I’m still not likely to go vegan on a permanent basis, it is something I can easily incorporate into my weekly meal plans. I learned about alternatives like cashew cream and I discovered wonderful trail mix recipes. Smoothies will remain part of my midweek routine at least in the summer. My greatest surprise was that I lost a few pounds toward the end. I eat small portions and healthy already so I didn’t think I could lose weight with nutrition numbers that I saw. I has been a very gratifying experience to see that I can do it at least in the short term and I look forward to trying it again.
I really enjoyed the Spring Cleanse. The recipes were delicious! The thing that was most helpful was how organized it was. Every meal, snack and drink was planned out for us with shopping lists! It was so easy to follow and I will definitely be making the recipes again and again!
I really enjoyed the challenge meals. I got many ideas for new smoothie & salad recipes (the best dressings too!) and there were great snack recipes. Meal recipes were easy to follow and tasty. I liked the structure of meal & snack recipes every day, which made me better at meal planning.
So I splurged and purchased this hardcopy to replace my much worn, greatly splattered mix of colored and b/w printed version from several years ago my husband printed for me at work week by week as we did the cleanse. Love having the digital access, and it definitely has it’s benefits, but for working in the kitchen for me nothing beats a nice color hard-copy recipe to follow. Love the cleanse! Great way to reset and restart each spring when soccer games and school activities have caused drive through fast food and less than healthy snacks to sneak way too far into our routine.
I have tried going plant based for a while. All the recipes I found were so blah. My garbage disposal ate more than I did. SGS recipes are so good. I’m looking forward to eating them again and again. They must have been kid/family tested and approved!😸 I also found the recipe directions to be clear, and accurate; so easy to follow. Loved the shopping list and prep plans. Made following so much easier. I lost 10# without ever feeling hungry. I often skipped snacks because I was still full from the last meal. I really feel I’ve pushed a reset button for my food cravings and eating habits. Highlights/Surprises:: strawberries + basil; quinoa with lemon juice; quinoa pizza crust(there’s got to be a way to make snack crackers with that recipe!) Thank you so much!
The 21-day cleanse is what the doctor ordered. The pandemic was hard. We went from working out regularly and eating fairly healthy to extra treats, sodas and junk food with no exercise. Everyone in my family gained weight. Then my husband had a heart attack. That was a major wake up call. Since then we have been eating vegan. I have wanted to do this fresh start cleanse for several years and decided to jump. My husband and I loved the meals and it has been a great plan to follow. We will definitely continue on this journey. Our weight is lower than pre pandemic and our energy is much higher. The support team has been fabulous, friendly and very helpful. If you are on the fence, just jump, it’s worth it because you are worth it.
The first week can be hard if your a heavy caffeine drinker (like me 🙂 but it’s worth it. If you work away from home you have to meal prep otherwise you will feel overwhelmed with the preparation needed. I do wish the recipes were based on volume and weight vs 2 volume measurements. I would much rather zero a scale and add in the correct weight rather than using all my measuring cups and spoons. I used this program as a spring board for an elimination diet for my doctors it was so much easier using this program with all of the support than going through it alone. If your needing to make changes to your diet but have no idea where to start this is the place.
Love everything about this cleanse. The food is right up my alley and the book is an added bonus to have in hand.
I enjoyed doing this cleanse with great recipes and supportive Facebook community! I lost 10 pounds, but more importantly I made some long-lasting good eating habits .
I love the recipes! The food is amazing and filling! Highly recommend!!
I enjoyed the foods during this the cleanse much better than the 21 day cleanse you put out a few years ago. All 7 days were phenomenal! of course, I do have my favorites like the coconut cauliflower rice, spiralized taco salad, berry bowl bash, my husband really loved the cauliflower soup! I am aiming to keep the momentum going for a few weeks hopefully! I have tried to have a green smoothie 5 times a week! With this the cleanse, I have had so much energy without my coffee, of course, it took about 3 days for it to kick in, but I was amazed! Thanks Jen!
Beautifully written with every step outlined. My husband and I were not able to start with the group but are starting tomorrow Feb 17. We are really looking forward to this the cleanse! I so appreciate all of your work on this project and your heart to help others be the healthiest they can be! Thank you!
As someone new to trying a plant based diet – I have found this book a wonderful resource to learn from. It is easy to follow / good layout.
