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 have done the Winter the cleanse in Dec 2019 and the Summer the cleanse in 2020. The Winter the cleanse made me become a Rawkstar Member because I wanted more. I have done the Smoothie Challenges and other events that SGS hosted, but I was at a point where I needed and wanted more. I am coming up on my year anniversary and I am so glad I joined. The Team and Members are the best group I’ve been apart of AND so so supportive. All the recipes move you to be open and try new things and maybe even some old things in a new and tasty way.
Love the layout of the plan, the fact that the meal plan is “clickable” as well as many of the delicious recipes shared via the plans!! Love ALL of the smoothies – do not make me pick just one! One of my favorite dinner recipes is the “Grilled Broccoli Steaks”.
One of the most amazing benefits of the cleanse was how it curbs the cravings! We discovered that once we get away from the sugar, we don’t want it. We mostly stay away from dairy, after realizing how much cheese and milk we were consuming! We use almond milk, but I still do buy cottage cheese because we like to eat that with fruit for dessert. My husband has always taken sandwiches for lunch, but after the cleanse he said he wasn’t ready for bread! Revamping our lunches has been a huge change, but it is well worth it. We may have lentils or beans and rice, plus fruit and nuts. We are more willing to try new foods or recipes now, because the cleanse opened our eyes to the fact that we can get full on meals that don’t have meat or pasta! We haven’t totally given those up, but I have been using chickpea pasta and use meat as more of a condiment. I used to be so intimidated by fresh produce, and now it feels half of our shopping cart! We still eat out once a week, that we have become more selective in what we order. The whole process has made us be much more in tune with how food makes our bodies feel, and intern we are willing to listen to our bodies! The biggest eye-opener for me was discovering how much emotional eating I was doing, and it prompted me to take a look at that. We have always enjoyed walking and hiking, but we have decided to go to the next level by beginning strength training. I hope all of this makes sense! It’s sometimes hard to put into words all of the changes mentally physically and emotionally that can come from changing the way you eat. The journey continues!
My husband and I both participated in the 21-day cleanse. I loved everything about this fresh start. The recipes were amazing and introduced me to different plant based meals that continue to be in my weekly rotation. This cleanse helped my husband kick his soda habit for a love of my green smoothies. We continue to use this platform to do a cleanse 1x a year. I am a firm believer that this fresh start skyrocketed my love of plants. Both my husband and I lost weight during the 21 days, but more importantly I became regular and I no longer felt bloated and full all the time.
The cleanse has certainly helped with my sugar cravings and while I have reintroduced meat and eggs I plan to eat a lot more greens and less meat. I enjoyed the meals more than I expected and the drinks are now a part of my day also. The apple cider vinegar and a snack of almonds ( especially the sweet version) get me through the afternoon without eating sugary treats.
The cleanse is amazing! The recipes are delicious! Your body will thank you at the end of the 3 weeks. It is a healthy and kind way to reboot your health & body. Follow the weekly prep guidelines and you will thank yourself later.
I loved how I felt finishing this cleanse. I loved the challenges and feeling of accomplishment. Who knew eating Whole Foods and skipping the coffee would give you so much energy, and I slept so much better at night! The extra clear soft skin was an added bonus too. Try this cleanse. Sometimes we stumble upon something that ends up being exactly what we need and this was it for me!💚
Really great recipes, menus, and prep and shopping lists. I didn’t feel hungry. I definitely felt like I was cleansed, even as early as week 1. Sticking with it for 21 days was an achievement and I’m glad I did it. I felt better. I could tell it reduced inflammation from arthritis because I had more endurance with walking and exercise. My digestion was better and I lose about 10 pounds whenever I do this cleanse. (I’ve done it for 3 years now.) It’s a lot of prep work but the more I make changes to the way I eat and doing the cleanses and resets on a seasonal basis every year, the prepping becomes easier and more “second nature.” I always do some meal prep work for the week now and there’s certain items from the cleanse I keep as part of my fridge or pantry now.
This is the cleanse that changed my eating habits forever and really sparked my passion for health and wellness. I have done Fresh Start Autumn multiple times over the past 6 years. The first time through, I followed the plan exactly, but now that I’ve learned what I like and don’t like, I can customize accordingly. They make it really easy to substitute ingredients and swap recipes as needed. I love how my body responds to being nourished with nothing but whole plant-based food for 21 days. I always feel great and sleep more soundly during this time. It does wonders for my cholesterol and I usually lose about 10 pounds. My least favorite part is the amount of time I have to spend in the kitchen between prep work, cooking and dishwashing, but the end result is always worth it. Prepping as much as possible ahead of time is a definitely the best way to ensure success. These recipes introduced me to how delicious plant-based eating can be, inspired me to try new things, and demonstrated how food really is the best medicine. My family and I enjoy using so many of these recipes even when we’re not cleansing!
I have done this the cleanse a few times now. It really helps get me back on track after I fall off the wagon, especially when I don’t have the time for the 21-day program. It keeps me in check and gets me excited about eating greens again as the recipes are so delicious! Great way to get started if you feel a bit intimidated or overwhelmed by the 21-day cleanse.
The group format of the cleanse alone is amazing. It helped me hold myself accountable and be consistent compared to if I had tried to do it on my own. Also being able to see others progress or swaps in the plan kept me motivated. This kicked all my sugar and caffeine cravings which were causing me to over eat. I’ve reset my hunger cues, increased energy so could get back into working out. No weight loss on the scale but I could feel less inflammation and water retention from before I started.
I felt great both inside and out!
I did lose weight. It’s great to know you are eating healthy and resetting your palate. I thought week two was pretty difficult. Other times I modified by allowing a minimal amount of coffee.
I can’t remember the exact date last year that I did my cleanse, just know there is NOTHING like this SGS version out there. I liked this cleanse because there was no…if you buy our $300+ bundle of supplements powders and otherwise unfulfilling shake drinks, you’ll lose X amount of weight. They duets rarely work to solve the real problem…our way of thinking. The Simple Green Smoothie way of thinking is a lifestyle change that helps the dieter to flip the switch inside us that craves processed unfulfilling foods for REAL/NATURAL savory and sweet alternative. The 21 Day is where it’s at because just like learning a new language you have to immerse yourself in the culture of eating healthy, fulfilling foods. This is a system where the reward isn’t just pounds lost (I lost the bloat and shed some weight), but also knowledge and health gained. I never felt so good inside my body so I could love the outside. 😉 My only enemy was myself on this cleanse. It’s hard to give up the processed sugars when it’s had been such a huge part of my diet pre SGS.
I have been a vegetarian for over 30 years and am raising my three kids vegetarian as well. It is very easy to fall back on starches as fillers for meals and in a face paced life- prepared and processed foods. It is also very easy in my busy life to put myself last~ Fresh Start is such an awesome reset! I did my first cleanse with the original 21-day cleanse (Autumn) almost 2 years ago. I had just come back from Switzerland with my family and had more bread and yogurt and cheese than any one person should have in a year. Fresh Start was exactly what I needed to reset and get back on track. Breaking from Caffeine was much tougher than I expected- but I started sleeping better and feeling better almost instantly. So when Fresh Start Spring was available I had no hesitation. The recipes are amazing- all whole foods, and the sauces are delicious. I love to cook but get bored with cooking and figuring out what’s for dinner, so this is amazing. I love having all of these recipes right at my fingertips! My family has really enjoyed a lot of it as well- so it is a win win all around. I can’t recommend 21-day cleanse enough!
