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.

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.

★★★★★Lynette C.

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.

Common Questions

Will I be hungry while on a detox body cleanse?

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.

Do I need to buy any powders, shakes, or supplements?

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.

How much will the groceries cost on the 21-day cleanse?

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.

Can I have coffee and tea while cleansing?

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.

What if I can’t have certain nuts, veggies, fruits, etc.?

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.

Can I go out to eat while cleansing?

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.

What are the side effects of the cleanse?

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.

How long does the food prep take?

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.

I have a crazy busy schedule, is this realistic for me?

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.

Who shouldn’t do a cleanse?

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.

Can I workout during the cleanse?

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.

Can my husband do this with me?

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.

What is your refund policy?

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.

I absolutely loved doing the 21 day cleanse! I’ve lost weight, gained energy and my skin looks great! I had been suffering with eczema for months and it completely cleared within the first week of the cleanse. My kids have also enjoyed helping me make all the smoothies and meals and it’s encouraged them to try a lot more healthy foods too. I loved having the support from Jen and the team all the way through as well. I couldn’t recommend enough! Thanks so much :blush:

Excellent and clear plan. Great recipes. So much digestible information and then they go above and beyond and do Live Zoom calls where you get to talk too!!! They didn’t need to do that for this low price point. Wow. My skin feels clear, my energy back, I feel like me again. Amazing!

This was one of the best things I ever did for myself! I have increased energy, I lost weight, I have a ‘fresh’ look about me. All in all, it was well worth the investment. There was amazing support on the Support group, and the Admins were well-engaged and offered great advice and support to my concerns or questions.

Sometimes you need a reset in life. This cleanse helped me develop healthy habits, provided amazing recipes, and offered great support. There were so many yummy things, but my favorite was the chili from week 1!

My honey and I are

My honey and I did the cleanse together. I didn’t expect him to be so into this! It’s so nice to have an accountable partner during the process. What we both raved about during this process is how incredibly flavorful the meals are. When we started this cleanse the thought of no meat, no dairy, no caffeine, no gluten and no alcohol (what?!) sounded boring and restrictive, but it has been quite the opposite. We feel full and have thoroughly enjoyed all of the meals. We feel lighter (10 pounds each!), healthier and full of energy!

I enjoyed this cleanse! The majority of the recipes were easy, quick and very tasty. I only had 1 that I did not like and it may have just been an off day for me. I rarely felt hungry, unless I did not prep and have my snacks and things ready to go. So,prepping is key! I would love to do more cleanses like this a few times a year and feel more energetic! Thank you for all the info provided in the cleanse and the support Facebook page.

I have been a fan of simple green smoothies for a few years and have done the 7 day smoothie challenges n loved them. My kids still ask for the beginners luck smoothie which my youngest has coined “hulk juice”:) I have also been overweight for far too long and am on the cusp of the age that my family members started taking BP meds. I decided to take the leap and I am so happy I have. The variety of foods is awesome and the support of the community is priceless. I love that Jen is checking in on us too and offering support and ideas for alternatives when needed. I have lost 12lbs and cannot imagine eating any other way. You’ve made me a believer YALL! I am so glad that Jens generosity has also extended the next week meal plan! I have already made my shopping list. My husband is even trying some of the meals and asking for more. THIS is huge!!! I have recommended the website and challenge to friends who’ve noticed my weight loss and asked what I’m doing cuz I definitely didn’t get here alone! Thank you so much Simple Green Smoothies for the invite to cleanse and all the support! Hoping that I can pass the lessons I’ve learned on to my kids and pique their tastebuds to try The seasonal flavors of fresh food!

I loved this 21 day cleanse! First, having support with the weekly calls was really encouraging with the tips and questions from the other cleanse warriors. Second, most of the recipes were easy and really yummy! So yummy, that even if I made extra for the week, they didn’t last as my husband and kids usually finished them off. So the downside, was more prep work for me (lol!). Lastly, the Support group was so encouraging. It was encouraging to get tips from other warriors and changes to the recipes (for picky eaters or people with allergies). It was also encouraging because if we don’t have to be perfect and just keep on the journey to eat better and understand our nutrition needs. Thank you so much for everything that you put into it! It is a bargain for getting the opportunity to get the support, learning how to meal prep and trying some easy & healthy recipes!

I was so impressed with this 21 day experience. The food was incredible, and I feel fantastic. Seriously. I love whole food plant based eating, but I wasn’t used to as much fat – avocado, nuts and seeds, yes, but not coconut oil and not even much olive oil. I can see how eating this way has helped me move away from less healthy snacking, because I wasn’t hungry. I released 8# – yay me! I LOVED the recipes, and will be using my favorites on rotation now. Thanks for an awesome experience! Regina Pirruccello
