JUICE CLEANSING, HONESTLY: EVERYTHING PEOPLE ASK US, ANSWERED Over seventeen years in the juicing business, I have done countless three day cleanses, plenty of one day cleanses, and several that ran past fourteen days. I have walked more people through three, five, and ten day cleanses than I could ever count. From 2012 to 2017, juice cleansing was a craze, and I was doing interviews and writing about it constantly. Fast forward to August 2026, and you might ask what more there could possibly be to say. The answer is simple: the truth, minus the hype. So here are the questions people actually ask when they walk into goodsugar, see a wall of juice, and feel overwhelmed.
WHICH JUICES AM I SUPPOSED TO DRINK? Here is the most important thing on this page. The benefit of a juice cleanse is not that there is magic in the juice. The magic is in what you stop doing. A cleanse is a reductionist diet, meaning you have eliminated all the dietary mistakes at once. You are not eating processed food. You are not eating too much protein. You are not eating late at night. You are not eating all day long. You are not eating too many calories. You are not miscombining foods. Because of that, your body gets immediate relief, and the longer you go, the more those improvements take hold. What improvements? It is different for everyone, and I do not know your chemistry, so I will not pretend to give you a before and after diagnosis. Commonly, you will feel less bloated, lighter, and clearer.
IS THERE ANY ORDER TO THIS? No. As a person who makes his living selling juice, I wish it were that complicated, like a Harry Potter incantation that has to be said at the right moment, in the right light, at the right location. There is nothing like that in this kind of diet. It makes no difference whether you start your day with a deep green juice and follow it with pineapple, or the reverse. The flexibility is the point: drink the juices you like in the order you like. Just be aware of one thing. If you are on a very green, no fruit cleanse, you are on a very low calorie diet, and you will have less energy and feel tired. If you have to go to work, use your brain, exercise, or walk, you are going to need more calories, and on a cleanse the only place to get them is fruits and starchy vegetables. Do not be afraid of those. They have real benefits for every body type.
And a word about the all green, no fruit programs, like the candida cleanses. There is no solid scientific data showing that starving your entire system of every form of sugar is effective. If anything, the logic runs the other way: deprive the body of the carbohydrates it needs and it is the healthy cells that go weak and tired, while the troublemakers scavenge whatever is left. So why do so many books and juice bars get this wrong? Because there is a lot of pseudoscience out there. Just as the pharmaceutical and medical world is not perfect, the juice bar guy is not perfect either. Buyer beware, in both directions.
WILL I LOSE WEIGHT? Maybe a pound or two on a three day cleanse, but that is mostly water and a calorie deficit, and it does not necessarily stay off when you return to solid food. Weight loss should never be the goal of a short cleanse, because frankly it is not an effective way to lose weight. If you want to drop a few pounds to fit into an outfit, you are better off with a simple calorie deficit and hard workouts. The real benefit is something else entirely: a pause from the addictive eating patterns we have been running for years. Not sitting down to your usual meals, not chewing, not chasing flavor explosions all day, it is a surprisingly profound psychological experience. Think of it as a meditation, a short retreat from eating habits that were not serving you.
WHAT ABOUT ALL THAT SUGAR? Put that worry down for a few days. The sugar we are all trying to avoid is not the sugar in beets, apples, and pineapples. Not all sugar is the same, and not all sugar hits your chemistry the same way. Refined sugar is concentrated, stripped of every companion nutrient, compacted into something far more potent. Eat a tablespoon of fresh cut apple and a tablespoon of white sugar and you cannot seriously believe your blood sugar responds identically. So when you look at a juice with fruit in it, think healthy carbohydrates, healthy calories, healthy fuel. Some of this is metaphor and some of it is chemistry, and for the sake of this lighthearted flyer, take it as a useful generality rather than exact science.
WHERE WILL I GET MY PROTEIN? There are amino acids in fruits and vegetables. You will not be getting much protein for three days, and here is the thing, you do not need much for three days. Your digestive system always has amino acids available to work with, and the human machine is designed to run primarily on carbohydrates. You have reserves. You will be fine.
WHAT ABOUT FIBER? Look at the bottom of the bottle. The reason juice is not transparent, the reason something settles, is that trace fiber remains in every juice, enough to stimulate digestion and enough prebiotic material to feed your probiotics. This is not a concern.
HOW IS THIS DIFFERENT FROM A WATER FAST? Night and day. A water fast gives you no calories and no nutrients beyond whatever is in the water, which is why it is so much harder. A juice cleanse gives you plenty of carbohydrates, vitamins, minerals, phytochemicals, and antioxidants. You are fed, just differently.
HOW SHOULD I DO MY FIRST CLEANSE? Start the first day with one of our smoothies and about four juices. Keep the day gentle. You do not need ninety minutes on a treadmill, try light yoga or walking instead, and see how you feel. Skip the coffee and other stimulation if you can, cleanses are far less effective when you pour stimulants on top of them. And know this from the old days: we used to give people too much juice. Six sixteen ounce bottles was the standard prescription from Dr. Norman Walker, who invented one of the great cold press machines of his era and lived to ninety nine. My mentor Fred Bisci, ninety six as I write this, taught me to understand the chemistry of all this without disappearing into abstraction. Less can be more here too.
A FEW HONEST CAUTIONS: If you are sick or uncertain in any way, talk to your health care provider, do not rely on a flyer or a juice bar to tell you how to get well. If you take medication, three days of juicing should not change it, but never adjust or stop medication without your doctor, and on longer cleanses check in with them, because as the system cleans up, some things can feel stronger. One more truth from someone who writes books about this: if you live with high anxiety, compulsive habits, or addictive patterns, stepping away from your ordinary diet will change how your nervous system feels. Sometimes that means a wave of anxiety, sometimes it means feeling wonderful. There are too many combinations of human being to tie this up in a bow, so go gently, and treat the cleanse as what it really is, a few days of rest for a body that rarely gets any. goodsugar. Real food, real chemistry, no hype.
