Your gut’s been through it
Bloat, heaviness, the whole uncomfortable mess.

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

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 enjoyed this cleanse! The food was delicious and didn’t take too much time to prepare. The shopping prep list was really helpful too! I also enjoyed seeing other posts on how others were doing with the cleanse and seeing photos of the food everyone made. I will definitely do it again!
The cleanse was a great way to help clean up my diet and find tasty easy to make replacements for foods that are high in calories. I’ve lost some weight while still enjoying meals. It’s been a great experience!
While I can thoroughly recommend the 3-week Spring Cleanse, I didn’t really enjoy the Summer Cleanse. The interactive plan, shopping list, and easy to follow recipes are wonderful! I love smoothies for breakfast, but I don’t want another smoothie for lunch. I ended up doubling the dinner recipes, as in the spring cleanse, and eating those for lunch. I also didn’t enjoy the turmeric or metabolism teas because they made my stomach hurt. I prefer the Detox Tea from the Spring Cleanse. The Summer Cauliflower Salad was amazing!!
This was one of the most delicious and fun cleanses I’ve ever done. I thought going 100% plant based would leave me feeling hungry and exhausted. I was surprised to find I slept better and had more energy than I could’ve imagined. I looked forward to the variety of yummy foods at each meal and the snacks kept me satisfied. I followed the prep guide and prepped all the smoothies ahead, which made it easy to start the day and stay on plan. I plan to incorporate many of the recipes into my eating plan going forward. Thank you Jen & Team for creating this program!
Traveling the week of the cleanse so completed the week before. Sorry to have missed the community support, but glad to have completed the cleanse! My husband joined me for the dinners, so that helped. First few days were a lot with the shopping and prepping. My purpose was to the cleanse my choices to more plant based eating by remembering how much better it feels to do so! Mission accomplished!
I joined to kickstart better eating habits that included more plant-based meals and to get a jump on some weight loss. I had done the 21-Day Cleanse several years ago and felt amazing afterward and loved all of the food so I knew I would enjoy this cleanse. This was a little tougher than the 21-Day Cleanse since there is no rice or beans and I felt hungry a few times (ate some nuts) and definitely had some cravings especially on days 4-5 but I was craving rice and beans (which is great!) and not sugar which is my nemesis! I have stuck to the plan 100% and definitely feel great and have a lot of energy. I can see that I am less bloated and feel like I’ve lost a few pounds (scale tomorrow am). I am proud that I stuck to it even when I had some cravings and was a little hungry! I’m also proud of myself for taking a step towards better health overall. I’m hoping that I can continue to stick to smoothies and fruit for snacks and stay off of sugar.
I joined the cleanse because I am a mid forties very active woman (I just backpacked 150 miles on the Pacific Crest Trail!) but I continue to gain weight. I also saw my family going down a path I wasn’t comfortable with regarding their food choices… so this was a great jump start to focus on nutrition for me and I got the whole family involved! I’m now extremely motivated to continue the Whole Foods mostly plant based journey. One week and I could really see and feel a difference!
The cleanse came at the perfect time. I’d gained a few unwanted pounds and was dealing with bloating and fatigue. This was just the motivation I needed to the cleanse and get back on track. I was pleasantly surprised during the cleanse how good the recipes were although I quickly learned the importance of including the snacks and teas to keep me on track and keep hunger at bay. Bonus: my coffee and chocolate/sugar cravings were never an issue this past week and I lost 4 lbs! I want to keep the momentum going and continue to put wholesome food into my body even as I transition off the cleanse. I’m proud of sticking to it and seeing it through – definitely worth every penny!
I am going through menopause and nothing was working. Not only was the weight hard to get off, it was also easy to gain. I needed a the cleanse. I loved the simplicity of the the cleanse. The support during the cleanse was amazing.I am proud of myself for sticking with it. I lost 5 lbs and inches in my waist. I also feel more energized.
I joined the cleanse because I felt a disconnect between my mind and my body. I knew I was eating poorly, and I knew what I should be eating, but could never seem to get my body to listen to my mind. “But I WANT cookies, so I’m going to eat them.” The first days of the cleanse were rough. Withdrawals from caffeine and sugar weren’t easy. But the cleanse kept me satisfied, and I craved them only a couple of times. By the end, I felt as if I was lighter, cleaner, and moved more nimbly. I feel as if my body woke up. In fact, I experienced the connection between healthy food, nourishment, and feeling good. I’m proud that I decided to take action on a problem that was bothering me for a long time, especially because it required more food prep than I like. I’m excited to keep riding this train.
It was hard to stick to the diet at work. I do not prep in advance, and I don’t have ice cube trays. I feel lighter and stronger! I am proud of having enough willpower to do this. Thank you!
The reason why I joined to see if this would help with inflammation issues and to learn how to eat healthy with less meat. Meal plans have opened my eyes and awaken my taste buds to marvelous meals. I was pleasantly surprised at how filling and satisfying the meals and smoothies are and plan to incorporate in my life going forward. I feel pretty good, less bloating & my sweet cravings are way less and my desire for potato chips (my most favorite snack) has subsided greatly. I completed the program almost perfect.
This really helped me cut down my caffeine intake and eat healthier all around. Great recipes! Going to keep some of these in my normal rotation.
I joined the cleanse because I have been struggling with my digestive system and I was several pounds above my usual weight and could not get rid of them. I also was out of control with my eating and needed to regain that. Going through the program, I noticed I really wasn’t hungry and decided on a way to improve my eating habits after the cleanse. Now, aside from eating plenty of carbs before the cleanse, I was used to having daily green smoothies, so that was not hard to get used to. I did manage to lose a few pounds, but I know I will gain at least a couple of them back, as it isn’t practical for me to continue the same plan. I was also very tired during the cleanse, so I can’t say I had increased energy, because I had less, but I really don’t think it was the cleanse. My energy level was already spiraling down. My digestion did not improve either, unfortunately. However, I have Hashimoto’s thyroiditis and my thyroid levels have been unstable for at least the last 6 months, so I plan to get another thyroid level done soon and seek further treatment as needed. I am proud I lost a little weight and that I gained better control over my eating habits.
Through the cleanse, I found more clarity, better quality of sleep, less bloating and even lost a few pounds. I will continue to embrace this change of eating habit it has helped tremendously!
