This cleanse is for you if…

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.

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 was intrigued by the winter cleanse. The recipes looked delicious and they really were. Some of my favorites include the kale salad trail mix tropi-avo salad ambrosia salad berry bowl mango carrot smoothie maple bowl. I could go on. Yes I did go through detox with headaches and feeling sluggish in the beginning but when the fog clears it feels really amazing. I did lose a few pounds with eating so much food! I will continue the turmeric tonic in the mornings and the ACV tonic before dinner. I have learned so much and enjoyed the journey along the way. Thank you SGS!!!

For once I wasn’t hungry on this cleanse. I think having the 2 daily snacks and the apple cider tonic helped. I really liked the daily e-mails to keep us motivated and on track. The dinners were simple to prepare and 😋 delicious. Thank-you for a successful week. I look forward to continuing on the maintenance program.

I’m so happy I decided to do this the cleanse. It was a little overwhelming before starting with the shopping and prep but worth it. I’m glad I did most of the prep to make the days go easier. The best part, it made me try things I wouldn’t have normally ate and everything was very good. Plus, I now have some good habits that I will keep going everyday. The smoothies/food keep my full all day and most dinners were actually too much. Most recipes are keepers and I’ll make again. Thank you Jen and Team for all your support!

The perfect the cleanse. I highly recommend. A lot of my friends have done cleanses where they starve themselves. This is a healthy cleanse with so much food that most days I could not eat it all. My advice is go in with someone else. There’s a lot of food and groceries to buy. Splitting it would be a great option.

I have been doing these cleanses and challenges for the past year and I love them! They are easy to follow and there is so much support from the team and other participants in the Support group. Doing the cleanse is a challenge at first, even when you have done a few, but I started seeing benefits right away. This is just the motivation I need to see it through to the end. I am always reminded of how great it feels to embrace a plant-based lifestyle. The recipes are phenomenal, even when at first you might think it looks like a dish you wouldn’t initially gravitate towards. I always learn something about cooking with each cleanse. Following this program is one of the best decisions I have ever made for my health!

This was the first cleanse I have ever done. I have heard nightmares so I wasn’t sure what to expect with the cleanse. I was not disappointed! It certainly takes a lot of time and effort to eat healthy but I am glad I did it. There were days the food was too much for me to eat so I stopped eating when I was full. Would highly recommend this cleanse. Looking forward to continuing on my plant based journey with the maintenance

My husband and I have never done a cleanse before and were hesitant to start this one. But Jen’s book made everything so easy to follow! Instructions were clear, the photos were appetizing and accurate, and the book answered all of our questions as we walked through the days of the detox. We are so pleased with the way we are feeling.

Since I try to stick to a fairly healthy diet, I didn’t feel the need to be extreme but thought it a good opportunity to move toward getting more vegetables in, cut back on the coffee, and do without red meat & processed foods and the Christmas candy that I had been getting addicted to so I followed the plan but had a cup of coffee in the morning and a glass of wine at night and had a portion of chicken, turkey or salmon at dinner. I enjoyed a lot of the recipes and it’s a good opportunity to try different foods than we generally eat. We loved the Mediterranean Squash bowl and plan to have that again this friday. I loved the vanilla/camomile/lavender latte and will have that again. I discovered that a spoonful of ACV in water is good and may continue that before dinner. And hopefully we can continue reducing our consumption of red meat & processed foods, drink more water and eat more vegetables, having gotten through this week fairly successfully. The shopping lists and weekly plan were so helpful and the support and encouragement were much appreciated. Thank you!
