Four to six bottles of cold-pressed juice, totaling 800 to 1,200 calories per day, replace every meal for five straight days in this format. That deep calorie deficit is why most adults see the scale drop 3 to 7 pounds by the end of the week, though the loss is mostly water and stored glycogen rather than fat, and the pounds tend to return once normal eating resumes.
This article explores what realistically happens during a five day juice cleanse, covering the day-by-day experience, the science behind the weight loss, and who should sit this one out.
What a Five Day Juice Cleanse Actually Involves
Structured liquid-only eating plans swap every meal for fruit and vegetable juice over a five-day window in this approach. Most programs deliver 4 to 6 sixteen-ounce bottles spaced roughly two to three hours apart, aiming for 800 to 1,200 calories from juice alone. That range sits well below the 1,800 to 2,400 calories most adults need for weight maintenance, which is why cleanses often feel like fasting even though you’re still consuming something.
The Typical Daily Structure
Most commercial cleanses label each bottle by number or by function, then ask you to drink them in order. Bottle one is usually a lighter green juice for morning hydration, bottle two might be a beet or root blend for midday energy, and bottles three through five rotate between cucumber-mint, citrus, and a final green to close the day. Water and herbal tea are encouraged between bottles to keep your total fluid intake up.
At home, the same rhythm works with a centrifugal or masticating juicer and a printed schedule taped to your fridge. Spreading bottles across the day matters because it spreads sugar intake across the day instead of loading it into one or two large drinks, which helps blunt the blood sugar swings that cause headaches and crashes on lower-calorie days.
Why Five Days Sits in the Middle
Three-day cleanses are the most common entry point because they fit a long weekend and produce noticeable scale changes. Seven- and ten-day programs exist but require a more serious commitment and carry higher risk of muscle loss and electrolyte issues. The five day version is often pitched as the sweet spot: long enough to feel like a real reset, short enough to finish before your social calendar catches up.
The modern juice cleanse market took its shape from Stanley Burroughs’s Master Cleanse, a 10-day lemonade-and-maple-syrup protocol he promoted in the 1940s. Today’s green-and-beet programs are a more nutritionally complete descendant of that original, but the short-term, all-liquid format carries over directly.
Cold-Pressed Versus Heat-Pasteurized
A hydraulic press extracts liquid without generating heat in this method, preserving more heat-sensitive vitamins and plant enzymes than a standard centrifugal juicer. Commercial cleanse brands like Pressed and Raw Generation built their reputation on cold-pressed processing because the resulting juice stays nutritionally dense for the 3 to 5 days it sits in a refrigerated bottle.
Heat-pasteurized juice, the kind on most grocery shelves, is heated briefly to kill bacteria and extend shelf life, but that process degrades some vitamin C and certain enzymes. For a multi-day cleanse where juice is your only food source, that nutrient retention matters more than it would for an occasional breakfast drink.
That gap between marketing claims and real nutrition sets up the question of what, if anything, the body is actually doing during a cleanse.
The Science of Cleansing and What the Evidence Actually Shows
The most common claim attached to a five day juice cleanse is that it removes toxins from your body. Your liver and kidneys already do that job, continuously, and no peer-reviewed study has shown that drinking juice for several days improves their function. Your body has its own detoxification systems, and no specific juice protocol is required to support them, a point the National Center for Complementary and Integrative Health has made consistently in its consumer guidance.
Where Short-Term Results Actually Come From
The weight loss you see on a five day juice cleanse is real, but its source is mostly water and glycogen depletion. Your body stores glycogen in muscles and the liver alongside water, and when you cut calories sharply, that glycogen gets burned and the water tied to it leaves with it. That is why the first 3 to 7 pounds often come off fast and why they often return within a week of normal eating.
The calorie deficit itself is the main driver of any short-term results. A 5 day juice cleanse for weight loss works in the same mechanical way any low-calorie diet works, by forcing your body to tap stored energy. Juice composition matters less for the scale than the total daily calorie count.
What Research Says About Markers and Claims
Small studies on short-term juice-only diets have found modest reductions in markers of oxidative stress and inflammation, but the same changes show up with any calorie-restricted eating pattern, including plain fasting. Claims about clearer skin, better digestion, and reduced bloating are widely reported anecdotally, and they likely come from a combination of higher vegetable intake, more water consumption, and the absence of processed food rather than any specific property of juice.
The scale moves quickly during a juice cleanse, but the scale is not a measure of fat loss. Until glycogen stores refill with normal eating, the number tells you about fluid, not body composition.
What the data does not support is the idea that juice cleanses flush toxins, reset metabolism, or cure any condition. Those framings show up in marketing because they sell bottles, not because clinical trials have confirmed them.
With the evidence landing squarely against grand promises, the practical question becomes who can reasonably try this at all.
Who Should Avoid a Five Day Cleanse and Who Can Tolerate It
A five day liquid-only plan is not safe for everyone, and the people who need to skip it are not edge cases. Diabetes, pregnancy, kidney disease, a history of eating disorders, and anyone on active medication that affects blood sugar or blood pressure should not attempt a five day juice cleanse without direct medical supervision, and most providers will recommend against it altogether.
Medical Situations That Rule It Out
Pregnancy and nursing require consistent calorie and protein intake to support fetal development and milk production, both of which a juice-only plan cannot provide. Type 1 diabetes and insulin-dependent type 2 diabetes are equally off-limits because the blood sugar swings from a 1,000-calorie day of fruit-heavy juice can be dangerous. Kidney disease restricts potassium and fluid intake in ways that conflict with most cleanse protocols.
Anyone with a current or past eating disorder should approach a it with extreme caution, since the restrictive structure can trigger relapse. If you are on blood pressure medication, blood thinners, or diuretics, you also face real risks from the rapid fluid and electrolyte shifts a cleanse produces.
Side Effects to Expect and Manage
Even healthy adults commonly experience headaches, fatigue, dizziness, and hunger during the first two to three days of a it. The headaches usually come from caffeine withdrawal if coffee was part of your pre-cleanse routine, while the fatigue comes from the calorie drop. Blood sugar swings from low fiber and low protein intake can also produce shakiness, irritability, and difficulty concentrating.
- Headaches: Most common on days 1 and 2, often tied to caffeine withdrawal. Hydration and a small amount of mineral water help.
- Fatigue: Expected on low-calorie days, especially in the afternoon. Plan a lighter workload if possible.
- Dizziness: A sign to sit down, drink water, and consider whether you need an electrolyte boost.
- Hunger and cravings: Peak on day 1 or 2, usually fade by day 3 once your body adjusts to burning stored energy.
- Blood sugar swings: More common if juices are fruit-heavy. Balance each bottle with a green or vegetable juice.
Warning Signs That Mean Stop Now
Fainting, heart palpitations, persistent vomiting, and confusion are not normal side effects. They signal that your body is not tolerating the protocol, and the right response is to stop the cleanse, drink water or broth, and contact a healthcare provider. Severe bloating, blood in stool or urine, or a racing heart that does not settle within an hour all warrant immediate medical attention rather than a wait-and-see approach.
Most registered dietitians recommend a provider consult before any cleanse longer than 2 to 3 days, and that recommendation is especially firm if you have a chronic condition, a low baseline weight, or a history of restrictive eating.
Preparing Your Body and Choosing Your Juices
Going from a normal diet straight into five days of juice is a recipe for the worst side effects. A one-week pre-cleanse phase that steps down caffeine, alcohol, dairy, and processed food gives your body time to adjust and dramatically reduces the severity of the headaches and fatigue most people hit on day 1.
The Week Before You Start
Seven days out, cut alcohol completely. Five days out, drop coffee to one cup and switch the rest to green tea. Three days out, remove dairy and processed food. One day out, eat light: steamed vegetables, brown rice, lentil soup, nothing heavy or spicy. This taper is the single biggest predictor of how the first two days of the cleanse will feel for you.
Increase your water intake during this week too, aiming for 80 to 100 ounces per day. Hydration going in reduces the dehydration symptoms that often get misread as detox side effects once the cleanse starts.
DIY Versus Store-Bought Programs
The main decision before starting is whether to juice at home or buy a pre-made program. Each has tradeoffs in cost, time, and quality. The table below lays out the practical differences for a five day cleanse for someone weighing the two options.
| Factor | DIY at home | Store-bought program |
|---|---|---|
| Five-day cost | $60 to $120 in produce | $200 to $400 delivered |
| Time per day | 45 to 90 minutes juicing and cleaning | 0 minutes, ready to drink |
| Juice quality | Freshest possible, drink within 24 hours | Cold-pressed, 3 to 5 day shelf life |
| Equipment needed | Masticating or centrifugal juicer ($80 to $500) | None, bottles included |
| Schedule planning | You build it | Pre-planned by the brand |
If you already own a juicer and like cooking, DIY wins on cost and freshness. If your schedule is packed or you don’t own a juicer, a it from a brand like Raw Generation or Pressed removes the planning work and delivers a tested schedule.
Recipe Categories to Rotate
A good it plan rotates through four recipe families so your body gets a mix of sugars, vegetables, and herbs. The rotation also keeps taste fatigue down, which matters more than people expect on day 3.
- Green: Kale, spinach, celery, cucumber, green apple, lemon. The workhorse of any cleanse.
- Beet and root: Beet, carrot, ginger, apple. Higher natural sugar, best earlier in the day.
- Citrus: Grapefruit, orange, lemon, turmeric. A good mid-afternoon option to lift your energy.
- Cucumber-mint: Cucumber, mint, lime, a touch of aloe. Hydration-heavy and easy on your stomach.
Reading Commercial Cleanse Labels
Not all store-bought juice programs are created equal. Check the sugar content per bottle: anything over 30 grams of sugar in a 16-ounce juice is likely fruit-heavy and will spike blood glucose. Look for added sweeteners like agave or cane sugar, which add calories without adding nutrients. Protein should appear on the label, even if it is only 2 to 4 grams per bottle, because some level of protein helps preserve your lean mass during a low-calorie week.
If you have specific dietary needs, look for programs that publish their ingredient lists in full and avoid proprietary blends. Fruit-forward products are typically loaded with simple sugars and may not be the right fit for someone managing blood sugar.
The Day-by-Day Experience and Staying Functional
Knowing what each day feels like makes the it far more manageable. The first two days are the hardest, day 3 often brings a surprising energy lift, and days 4 and 5 settle into a routine. Planning around that arc turns the week from an endurance test into a structured project.
What Each Day Actually Feels Like
Day 1: Hunger hits hard, especially around the times you would normally eat. A caffeine-withdrawal headache may show up by mid-afternoon. Energy drops after lunch. Mild irritability is common.
Day 2: The hardest day for most people. Cravings peak in the morning, and fatigue feels heavier. Some people experience lightheadedness when standing up quickly. Hydration matters more than ever.
Day 3: A turning point for many. Hunger quiets down noticeably, mental fog lifts, and energy often returns. Sleep may feel deeper. Your body has shifted into ketosis, burning stored fat for fuel.
Day 4: Routine sets in. Most people report steady energy, fewer cravings, and a sense of lightness. This is the easiest day to get through.
Day 5: Energy stays stable. The novelty of juice-only meals wears off, and thoughts turn to refeeding. The end is in sight, and most people feel ready to break the cleanse by evening.
Managing Cravings and Social Situations
Plan around the meal windows you would normally share with others. If lunch with coworkers is a daily ritual, schedule a walk or a tea break instead so you are not sitting with food you cannot eat. Dinner at home with family can still happen, just without your plate. A glass of mineral water with lemon gives you something to hold.
Cravings usually pass within 20 minutes if you wait them out. Distraction helps: a short walk, a podcast, washing the dishes. Most cravings during a 5 day juice cleanse are psychological rather than physical by day 3, because your body has already adjusted to the lower calorie load.
Exercise During the Cleanse
Light walking, gentle yoga, and easy stretching are fine throughout the five days. A 20 to 30 minute walk in the morning or evening keeps blood flowing without requiring fuel you do not have. High-intensity training, long runs, and heavy lifting are not recommended, because your body is running on a 1,000-calorie day and cannot recover from intense work without more protein and carbohydrates than juice provides.
Listen to your energy. If a planned workout feels heavy, skip it and walk instead. Pushing through a hard workout on a low-calorie day often backfires with dizziness, nausea, or a multi-day recovery that defeats the purpose of the cleanse.
Breaking the Cleanse and Keeping the Results
How you end a it matters as much as how you run it. A sudden jump from five days of juice to a large plate of solid food is a reliable way to trigger bloating, cramps, and a sharp blood sugar crash. A two to three day refeeding protocol protects your digestion and helps you hold onto the momentum you built.
The Refeeding Protocol
Day 6 (post-cleanse day 1): Start with a blended green smoothie at breakfast, move to a vegetable soup for lunch, and a small portion of steamed vegetables with quinoa for dinner. No raw vegetables, no red meat, no dairy, no gluten.
Day 7: Add a soft protein source like scrambled eggs, fish, or well-cooked lentils. Include a small portion of complex carbohydrates such as sweet potato or brown rice. Chewing returns, but portion sizes stay modest.
Day 8: Normal meals resume, but keep portions at 60 to 70 percent of pre-cleanse size for a few more days. Continue avoiding the heaviest fried and processed foods for at least a week.
What to Eat After a Five Day Juice Cleanse
After a it, your digestive system has had almost no fiber or solid food to process, so reintroduce both gradually. Your first solids should be easy to digest: blended soups, steamed vegetables, soft grains, and well-cooked legumes. Lean protein like baked fish, eggs, or tofu can appear by day 7. Fermented foods like kefir or sauerkraut help repopulate gut bacteria after a liquid-only week.
Drink water steadily, not in large amounts at meals, since your stomach is smaller than usual and floods easily. Wait at least 30 minutes after a juice before eating solid food, and stop eating at the first sign of fullness.
First Foods That Work Best
The most useful first foods are warm, soft, and lightly seasoned. A miso broth with tofu on day 6, a lentil and vegetable soup on day 7, and a piece of baked salmon with roasted zucchini on day 8 give your gut a chance to wake up without being overwhelmed. Avoid raw salads, carbonated drinks, and spicy food for the first 48 hours of refeeding, since they can all cause discomfort after a liquid-only week.
Reading the Scale After the Cleanse
Water and glycogen, not fat, account for most of the number showing on the scale the morning after the program. Once normal eating resumes, your body refills glycogen stores and the water tied to them, which often brings back 2 to 4 pounds within a week. The fat loss that did happen is real but small, usually a half-pound to a pound and a half over five days at that calorie level.
Do not chase the low number with more restriction. The momentum worth keeping is the habit: more vegetables, more water, less processed food. Those changes hold the fat loss over time in a way that a low scale reading never can.
Translating Cleanse Momentum Into Habits
The most useful thing a it can produce is not a number on your scale but a reset in daily eating. Keep the parts that worked: a green juice in the morning, a vegetable-heavy lunch, water between meals, and a smaller dinner. Drop the all-or-nothing framing that brought you to the cleanse in the first place.
If you want to repeat a juice cleanse, most nutritionists recommend waiting at least 4 to 6 weeks between multi-day cleanses to avoid repeated cycles of restriction and refeeding that can disrupt your metabolism and hunger signaling.
FAQ
How much weight can you lose on a 5 day juice cleanse?
Three to seven pounds typically come off across the five days, though water and glycogen rather than fat drive most of that loss. Once normal eating resumes, 2 to 4 pounds typically return within a week. The actual fat loss from five days at 800 to 1,200 calories per day is usually a half-pound to a pound and a half.
Is a 5 day juice cleanse safe?
Healthy adults without underlying conditions generally tolerate the protocol well, though headaches, fatigue, and dizziness tend to surface as common side effects. It is not safe for pregnant or nursing people, anyone with diabetes or kidney disease, people with a history of eating disorders, or anyone on medications that affect blood sugar or blood pressure. A provider consult is recommended before you start.
What should I eat after a 5 day juice cleanse?
Blended soups, steamed vegetables, and soft grains should land on the plate on day 6 to ease the digestive system back into solid food. Add lean protein like eggs, fish, or well-cooked lentils on day 7, and return to normal portions by day 8. Avoid raw salads, fried food, dairy, and spicy meals for the first 48 hours of refeeding to prevent digestive discomfort.
Can you exercise while on a juice cleanse?
Light activity like walking, gentle yoga, and easy stretching is fine during a juice cleanse. High-intensity training, long runs, and heavy lifting are not recommended because your body cannot recover from intense work on 800 to 1,200 calories per day. If a planned workout feels heavy, swap it for a walk and save the intensity for after the cleanse ends.
What happens to your body during a 5 day juice fast?
A metabolic shift from burning glucose from food to burning stored glycogen and then stored fat typically completes by day 3 of the fast. Calorie intake is well below maintenance, so your body draws on reserves. Common effects include hunger, headaches, fatigue, and noticeable water weight loss as glycogen stores deplete.
What can you eat while on a 5 day juice cleanse?
Only the 4 to 6 juices consumed each day, plus water and herbal tea, should supply calories during the five-day window. Some programs allow clear vegetable broth or a handful of raw vegetables in an emergency, but anything beyond that breaks the protocol. The point of the cleanse is the liquid-only format.
