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

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.
What a different SGS has made a difference in my life
I started SGS after reading about a smoothie challenge when my then Fiancé bought me the brand new top of the line vitamix with the aerator. I continued my simple green smoothies and then I did the spring challenge as well as the soup challenge and autumn cleanse. I am down to 195 I cannot believe I hiked The Pa’s Grand Canyon as well as Iceland’s National Park on my honeymoon and just last week we hiked the Great Smokey Mountains my wedding dress had to be taken apart and re made because I lost so many inches. Jen you changed my life For the better in the last two years I battled a rare blood disorder nearly died due to a strangulatied hernia and obstructed bowel then last year in 2020 I was carrying a tumor and had to have a radical hysterectomy.
Life Changing
I feel amazing! I lost 8 pounds and no bloating or aches and pains. Pretty sure I am not tolerante of dairy. The recipes are so good and as I cook I am surprised that the food does not need so many spices to add flavor! The lemon/lime citrus makes everything better. I have a couple shakes that I will make over and over. I picked my favorite recipes and added them to my Rawk The Year menu! Thank you for your encouragement your joy for our success really keeps you going! Thank you
Life-changing
OMG – this cleanse was AMAZING! I woke up this morning at 4:00 am (day 18 of the cleanse) with so much energy! This is my second cleanse (I did the one last spring) and it has truly transformed my life. Thank you Jen and team for putting together such a comprehensive and easy-to-follow program. I am feeling more confident that I can carry this well into the future.
Amazing experience
I loved this challenge! From the shopping lists to the Facebook support group, it was wonderful and so doable. I loved all of the recipes and family members even joined in with rave reviews. Below are two examples of my favorites. Thank you, Jen and team! I cannot wait for the next 90 days!
Great way to reset before the holidays!
I like not having to plan what it takes for a successful diet, so the day by day, meal by meal, snack by snack instructions and shopping lists are amazing! The adjustment wasn’t too bad for me as I am not a picky eater at all. Lucky for me I love cilantro! I did get a little tired of all the chopping and cleaning throughout the process, but I looked and felt great so it was all worth it. I wish I were more of a chef and knew what to add in here and there because a lot of the dishes did not have enough flavor for me. I will definitely be incorporating a lot of this as I go forward.
I did it! And so happy I did!
I’ve been following Jen and simple green smoothies for over a year and have become a fan of green smoothies! I saw the mention of her 21-day Cleanse…I’ve never been a fan of any “diets” so I didn’t think much about the cleanse. (Plus, “cleanses” are for fanatics, right?! 😉 At another of her mentions, I decided to read about it and thought that the purpose was congruent with my own health ideas and decided I’d give it a try! It was tricky to do because my in-laws have been living with us and they are not at all health conscious…how would I prepare my cleanse food and food for them simultaneously without them thinking I was crazy?! Anyway, long story short. Many of the meals, they had no idea it was part of my menu (sometimes I’d add some meat or bread or whatever for them) and in fact I made it 2 weeks before I even had to tell them I was eating differently! I have learned many things but I’ll mention 3: 1. I’m a snacker. Like all day long. Grab a little bag of Cheetos. A handful of chocolate covered almonds, an Oreo or 2, a peanut butter sandwich with grape jelly, chips and a Coke Zero, homemade cookies, etc etc. I have a major sweet tooth. This cleanse really opened my eyes to that. 2. My body feels healthy. I lost a few pounds, tho that was not the goal. I don’t feel the gut bloat I have felt for a few years (I’m nearly 50. I thought that was a new normal for me and I’ve hated that.) 3. I’ve learned eating healthy has to be intentional. It takes a little longer to prepare but the way I feel when I do is worth it! So, I have become one of those “cleanse fanatics” after all and I would highly recommend it to anyone!! (Plus, I have many new recipes to add into my weekly menus. I loved most of the recipes in the cleanse. Yum!!)
Didn’t think I would like it so much
Honestly, I am very surprised with myself that I have managed to follow this thru, 99% of the time. Although my usual diet is quite clean, with lots of vegetables, I used to give in to a couple of not-so-healthy snacks throughout the day, too-large portions during mealtime, and a glass of wine or beer “to relax”. I don’t need that! I feel fantastic, with lots of energy, and excited to keep going. And I saw the scale go down, finally entering the 2-digit kg range! I couldn’t be any happier. And just so you know, the remaining 1% was spent eating 2 small slices of cheese, consciously.
We are all Rawkstars
I loved the cleanse and learned a lot about my eating habits. I tend to munch and mindlessly eat. Having to prep really helped with good for you ready mad snacks available. Although I did find the prep a lot of work I do see how it will just get easier with practise. I really think the cleanse helped me to be more mindful of what I was putting in my body. I feel less bloated and lost 5 pounds but I really didn’t get the energy boost folks talked about though. Still feel that it was worthwhile. Thanks Jenn
Awesome Cleanse
I did the summer cleanse and enjoyed it, but found that 7 days was too short for me to really make a lifestyle change, which was my goal. I was excited to do the autumn cleanse, but nervous because I just had a baby 4 months prior and a 2 year old at home. The cleanse was AMAZING! It gave me easy ways to prep in advance and have yummy meals to eat. Now even my 2 year old loves zoodles with pesto!
This cleanse really works
This cleanse has been so good on so many levels — mostly being in charge of what I eat, eating purposefully and not absentmindedly or snacking on things I am not happy to eat because I let myself get too hungry. I loved blasting music while singing and dancing around the kitchen to prepare the meals! I had fun. I’m looking forward to continuing to learn more and getting more recipes. I love the simplicity of the recipes. I just finished a bowl of Jen’s granola with blueberries and almond milk. Deeelish!
Satisfaction
I’ve wanted to try a plant-based whole food diet for a while. The 21-day cleanse was the best opportunity to try it out & it was amazing! I was overwhelmed with all the meal planning & prepping (5-6 hours prep was no lie!) & the panic that all the food in my fridge & on my counter top would spoil before it could be consumed was worth it. Not a perfect cleanse, but I did it. I survived. I feel refreshed, cleaner & lighter. I recommend this for anyone wanting a change in their health. You won’t be disappointed, but you’ll be completely satisfied.
First ever cleanse, period. A 21 day cleanse to boot!!
Best thing ever!! I’ve lost 11 lbs in 19 days. That is great and all, but I’m not so much focused on the weight loss #, as I am on how I feel. I feel wonderful. I’m not hurting anywhere. Usually, being 60, I have a few aches and pains from time to time. The foods, the whole foods that this cleanse is all about, does a body wonders. I’m so thankful that I finally gave in and said yes, to this 21 day cleanse with SGS. At times it wasn’t easy. At times I was busy in the kitchen and wanted to be on the couch after 10hr work days. But it was all worth it. After my day#2 and day#3 headaches, I was good to go. Never had another headache. I was tired the first week and listened to my body and went to bed earlier. My sleep has been great too. It’s amazing to see how good you feel when eating and drinking the right things. I want to continue this way of eating. I do not plan to drink coffee anymore. I don’t need it. I pray that I can eat sensibly over the holidays and not lose myself in sugar. That is my downfall. I need to not take the first bite.
Beat my expectations
I have done these three week cleanses before so I wasn’t sure I would be inspired to really do the work and stay on it. But the community, daily emails and success really carried through. After three weeks I feel great, lost 5 needed pounds and am recommitted to staying on track for a healthy life.
I’m a Rawkstar
The Autumn cleanse was great. I can’t believe how much better I feel. I’m so energized and lighter and just ready to keep it going. Thank you for the wonderful and delicious recipes. I never felt hungry or had cravings. The motivational emails were a tremendous help to stay strong. I’m a Rawkstar now!
Almost Rawked It!
I thought this cleanse was great and I feel so much clearer! Although I wasn’t perfect, I almost rawked it! Three things I learned: I didn’t realize how dependent I was on coffee; I could easily be a vegetarian (but not a vegan); and I still really don’t like to cook (but I did it anyway!).
