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.

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.
So Easy!
The fall cleanse experience was amazing! I thought it was going to be tough and was a bit skeptical, but I was proven wrong. The smoothies, meals and snacks were easy to prepare and switch around if needed. The grocery lists made it easy to shop. Everything was so full of flavor and left my hunger satisfied ( no more late night cravings or snacking) I lost 10 lbs and got some energy back.
Great way to start on a plant-based journey
The cleanse is always a good way to reset and tweak what you are doing especially if you have been plant based for years. I like the fact that the meals are set for the day-this doesn’t mean you can’t switch things up but you have a 3 week plan to go by without thinking about it. There are also alternate recipes you can choose from. The recipes are quick, easy and tasty.
A doable, healthy reset!
I learned that the shopping guide and prep day were the key to success! It’s easy to eat the right things when you take the time to set yourself up to make good decisions when it gets busy or you’re tired.
Food was amazing
Boy where to start
It was so much to prep for the week BUT the week was sooo easy and to stay on track was a blessing. I felt successful every day. I feel a little lost today with no food presenting the fridge.
I’m a first time cleanser and this will not be my last.
First of all the mindset was everything for me. I went into this cleanse really wanting to give it my all and do my best. Other than having to adjust about three days to prepare for a colonoscopy, I stuck with it the whole time. The recipes were delicious; I never knew plant based meals could be so tasty. There are a few of things I’m not a big fan of (cucumbers & coconut come to mind right away) but I gave it my all. I still don’t care for cucumbers and ended up leaving them out of my salads, but adding them to my smoothies instead. My taste buds may have changed to be more tolerant towards the coconut, especially toasted. What was the biggest help in me getting through this was prepping my meals ahead of time and just grabbing the meal of the hour and heating up or blending up when it was time. I made a few meals for my family that were not on the cleanse and when I failed to eat before hand, I’d grab one of the teas to drink to curb my hunger until I could get to my meal; that did the trick. The grocery list was great, but the prep list was the most valuable asset in this whole cleanse. It really helped me set my week up for success. I’m already looking forward to trying out the one for the next season.
Love it every time!
Thank you again for offering such a wonderful cleanse and making it “easy” in that you put it all together for us, which takes out the thinking of what am I going to eat. This is my 4th simple green smoothie cleanse and every time I do it, I am shocked at how good my body feels. The biggest issue for me is gluten, and it seems impossible to stop eating it once I let it back in. This cleanse helps me jumpstart the removal in a positive way. It’s a huge bonus to have my husband on board doing it with me as well. It also feels good going straight into the holidays not feeling bogged down with inflammation, and hoping I am able to make better choices!
Life Changing!
I went into this cleanse hoping for a reset after a vacation and I got so much more than I imagined! I lost 10 pounds, got so much more energy back, slept better than I have in years and so much more! I got my confidence back and want to keep the momentum going forever! I’ve never been plant based before and I was a little skeptical at the beginning but I started seeing results immediately! I can’t wait for the next season cleanse!
Plant Based Cleanses Rawk
Love, love, love doing your cleanses! They always get me back on track and remind me that veggies aren’t boring. Plus they get easier each time. I was confused and a hot mess the first time around trying to follow the plan exactly. My fridge looked like it would explode with all kinds of veggies and leafy greens taking up every available inch. Now I’m more likely to use your menus as a starting point then customized to suit me and what’s available in my area. Please keep doing what you’re doing. Your effort and enthusiasm is appreciated!
There for me
I have been struggling with food cravings that are not healthy. The recipes have been delicious and I know I’m eating healthy foods. I appreciate your tips about handling all these fresh ingredients.
Glad I tried this cleanse!
This three week cleanse was so helpful to my health! I loved that it was only three weeks and that the menus changed weekly. I made it a point to drink my water and go to bed earlier, which I will continue to do. I made sure to follow every single recipe, which included many that I would never have tried on my own. I was surprised how good the food was and how well the flavor combinations worked. I also lost several pounds and just feel better overall.
The Best and Only cleanse
This is the one and only cleanse anyone ever needs. It is a life savor for someone like me, who needed help to finally get healthy.
Jen has put everything she has learned into a wonderful program to help people. Jen interacts with everyone and gives really good and helpful advice throughout the program. If you follow her program, you will lose weight. I did lose about 25 lbs., I learned that you have to prep ahead to be successful. I also learned that the cooking was a lot easier than I thought. I am not a cook, so for me that was a big advantage. The recipes are really good and tasty. I really learned that I could get over my cravings by going for a walk, and getting my mindset on other things, like the beautiful outdoors. I have never actually had a program work, this 21 day cleanse did.
Ready To Lose To Gain Everything
I gained so much knowledge about clean eating. I am ready for the next 90 days to continue eating mostly plant-based foods.
21-Day Summer Cleanse
As an anti-veggie girl, I was skeptical about trying this, but desperately needed better sleep and more energy. The meals were surprisingly good and the recommended weekend prep work made it “easy” to stay on track. Sleep improved and energy increased. Bonus, receiving a compliment on my skin and how refreshed I looked. I’ve also found that my sweet tooth is satisfied by natural sugars.
I thoroughly enjoyed everything about this spring cleanse. The recipes were delicious and I felt very nourished. I even served some of the recipes for a dinner party and got rave reviews. I am no longer craving sugar intense foods and I have lost a little weight. My skin is glowing and my energy is good. This isn’t the end of my cleanse its the beginning of a healthy way of eating. Thank you Jan
The prep guides and shopping list for each week are extremely valuable, without which, the program would be rather difficult to follow! I must say that the plant-based eating is such a more enjoyable way of nourish the body and I know that I benefited mind and body from the 21-day program (cleanse? I’d rather define it as a cleaner and healthier way of taking care of oneself). I’m thinking I should invest in your cookbook(s) for variety, inspiration, and exploration of different and new ideas. I did phone into the first group session in week one but was quite disappointed that after 15 minutes, it had not commenced. This would be my only negative comment. Apart from the aforementioned, I expect to participate in the next session.
