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

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.

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.
DO THIS CLEANSE ! I don’t do social media or any of those things, so this review is the Real Deal – honestly! First of all, it is SO clear that Jen’s heart and soul and passion and energy and commitment are the engine behind this. Grey smoothies were what I was choking down in 2016 because I knew what I wanted to do and had no idea how. Not to mention that I was coming up on my 1 year anniversary and wanted to lose the weight I had gained over the prior year. Enter Simple Green and Jen! My no meat life didn’t exactly = vegetarian: my diet was clean but boring and uninspired. And I knew that gluten was my nemesis and had been unable to stay away from it for any length of time. Because I was already eating mostly plant-based and unprocessed food, this cleanse was actually a relief. Shopping lists ensured that food wouldn’t go to waste, and the plan itself gave me structure and choices without rigidity. Although I lost weight (6 lbs) the shift in my willingness and choices and energy were the biggest payoff. And a plan that I have returned to for the last 4 years that puts me back on track. You can do it! This is an investment (and a small one!) that will pay HUGE dividends.
The recipes are very good 😊, really good stuff for you
Friends heard I was doing a cleanse (the first time around) and looked skeptical. I quickly told them- this is different- this is not a juice cleanse or starvation cleanse…this is whole foods- and lots of it! I found myself singing the praises- the recipes are all so good and really easy to put together, the flavors and spice- the sauces- all of it just delicious. There is an abundance of food to eat and I was never hungry, in fact, more than that, I felt satisfied. The hardest part was the caffeine withdrawal- I did have an awful headache for 4 days but that alone told me caffeine is something I will never get addicted to again, because why would I want to drink something that can do that to me?? It is very empowering when you decide you are going to put your health first in your life, especially if you have a busy life and take care of others. This cleanse makes me feel like I am pampering myself and I love it! My biggest suggestions are simple- 1. Commit to this time for you, and know that even if it is a challenge, for the next three weeks you are going to put your health and well being first. It is like going to a spa. 2. Shop ahead. Use the shopping list, read the recipes, know what you are going to make. 3. Prep. Can’t say it enough- especially the snacks- the stuff you can grab on the go- if you have those, you won’t reach for processed choices. 4. Be kind to yourself. You may follow this 100%, you may not- but be mindful in your choices and then be kind and forgiving to yourself and this will be a win for you.
The guides and plans are key to making this thing work….the fact that it is all organized and ready for me to just do is pure gold! I knew going in that I wouldn’t be able to complete 21 days, as I wanted to be part of the live cleanse group, but the time I did was enjoyable. We were really impressed with some of the recipes and there were a few we didn’t try, but everything we had was good. I felt good while doing it, though a little hungry at times. Definitely eat all of the snacks! This is really the best whole food cleanse program I’ve seen! Totally worth it, and I look forward to doing it again. My only caveat is that these foods are really more conducive to a warm weather cleanse. I did the program in October and I live in a part of the country that’s getting cold at that time of year! Salads and smoothies are just not exciting when it’s snowing out.
I’m happy to report that after three weeks, my clothes fit better, I FEEL better and I’m excited to move forward with a healthier lifestyle for my whole family that includes less processed food (including mindless munching) and more plant-based recipes that are creative, easy to make and delicious. My 2 1/2 year old son already loves green smoothies as much as i do! (We have completed several SGS 30-day smoothie challenges in the past.) A surprise bonus on this journey was the incredible support of the Support group who was going through this live cleanse together. Not only did giving and receiving support to fellow Rawkstars make this process easy, it made it FUN! I love this community and lifestyle!
I wasn’t sure what to expect when starting this journey but am so thrilled with the recipes and the results. The GS team have made this plan so easy to follow from the shopping lists to unique and tasty recipes with just enough flexibility to keep things interesting while still reaping the benefits. I lost 9 1/2 pounds and had so much energy. I did not miss meat, dairy or carbs and I plan to continue exploring more GS recipes and information as I continue to lead a healthier lifestyle.
The FS21 offer popped up on my Facebook news feed during a really social month and I was feeling flat from overindulging. It was perfect timing to give my body a break and re-establish some healthy eating habits. The cleanse featured down to Earth ingredients and easy to follow recipes, although I have to admit I did find the prep work a little exhausting at times but the food was truly amazing and it was so satisfying to know that we had prepared everything that we were eating for 21 days. Although I wasn’t looking to lose weight, I lost a kilo and my husband lost three! Our skin cleared up and even though we were busy and at times a little pressed for time, we just weren’t as stressed or moody. My husband was a fantastic support, doing the dishes while I cooked, helping with the shopping, and even learning to bake his own Warrior bars which he intends to continue post cleanse….and that’s a big deal because my husband does not cook…like EVER! He coped really well with the lack of meat, dairy and gluten, but he did struggle a little with the caffeine withdrawals. I would definitely recommend this cleanse to anyone in need of a reset. There’s no special pills or potions or patches, just an abundance of good, healthy, whole foods. We will definitely be doing this again!
Trying to change your eating habits seems like such a huge undertaking and there was SO much information out there, I didn’t know where to begin. Luckily, I found 21-day cleanse and started there. Today is the last day of the Spring 21-day cleanse for me and I have been amazed at how straight-forward it was with all the great step-by-step menus, shopping lists and prep guides. I am now using those materials and the fabulous recipes to create my meal plan for week four. Put yourself first and do this. You won’t regret it!
I am a die-hard carnivore so the thought of eliminating meat and cheese from my diet was almost a non-starter, and I wasn’t confident I could do it the whole time, but I was pleasantly surprised. Other than the deadly caffeine headaches on day 1-2 (since I didn’t taper down as advised!) I have felt great and not hungry. I am so happy to be free of caffeine and sugar and adding so many fruits and veggies to my diet! So far I have dropped 10 pounds and that is super exciting as well. I am planning on adding meat back in once I am done, but at reduced amounts, and incorporating many more vegetarian meals in my menu planning. I will probably also do this cleanse at least twice a year, maybe every quarter. It is exactly what I wanted it to be: A Fresh Start!!
I have always been a healthy eater and people tell me ‘Salad’ is my middle name. But I was not happy with the way my diet was going. I have hundreds of recipes but still spent hours trying to decide what to have to eat. Fresh 21 has given me a program to get myself on track. I have really gotten away from eating much meat so I needed to find more ways to get enough protein. I found my answer! The personal support I have recieived from the other cleansers (Facebook page) as well as the nutritionist and authors of the program has been so helpful. The recipes are fantastic and very satisfying. I have lost the feeling of a need for ‘something sweet’ after a meal. This program will not disappoint you. And don’t worry, once you finish the 21 day cleanse, they have you covered with additional help for the future!
This is an amazing program to learn how to eat plant-based and thrive! It is definitely challenging, but there is such a supportive and positive group to cheer you on, you get extra motivation to stick to it and go the whole 21 days! My partner and I have completed it successfully once, and are planning on doing it again together to give ourselves a “re-set.” The recipes are delicious, varied, and simple…you will not go hungry on this plan! Everything is laid out so clearly, from prep tips to shopping lists. I love the community, can’t wait to see what comes next! Thank you!
This my first time doing a cleansing diet. It has been an awesome experience. I feel energized in weed and half I have lost 7pound. I am very happy because I don’t crave anything other than my green smoothies. I feel clean inside out. It is blessing.
This was my first time with Fresh Start 21. I’ve done other cleanses before but could never complete them because the smoothie recipes made me gag and I never felt satiated. This was totally different! Every recipe is simply delicious and fulfilling. I never felt hungry and actually enjoyed every smoothie. I highly recommend this program.
I have always loved the idea of doing a cleanse, but always balked at living on just juice for a week, or taking crazy supplements, etc. That’s why I was so excited to find Fresh-Start 21. I’ve done the cleanse a couple of times now and just love how it makes me feel. It’s an awesome reset. The recipes are delicious, I don’t ever feel hungry (though if I do – I eat… It’s recommended!). It has changed how I eat while I am not cleansing as well, and many of the recipes are in my regular meal rotation.
I have never done a cleanse before so I have to admit that I was a bit skeptical. I have been following the green smoothie plan for a little over a year now and love it, so I thought why not try the cleanse. My husband and I are doing this together so it makes it fun and easier to prepare just one meal instead of something different for him. We both feel so much better, more energy and less bloated. My sleep cycle is so much better too. My husband has lost 12 pounds and I have lost 10. I would absolutely recommend this fresh start cleanse to my friends and family. Thanks so much for opening my eyes to a better way to cook, eat and enjoy foods that I never would have tried before.
