How long should a beginner do a juice cleanse?


A juice cleanse involves consuming only fresh fruit and vegetable juices for a set period of time. Many people try juice cleanses to lose weight, remove toxins, or reset unhealthy eating habits. However, there is debate over how long a juice cleanse should last, especially for beginners. This article examines the pros and cons of different juice cleanse durations for first-timers.

What is a juice cleanse?

A juice cleanse involves eliminating all solid foods from your diet and replacing them with fresh juices made from fruits, vegetables, and sometimes nut milks like almond or cashew milk. The purpose is to flood your body with vitamins, minerals, and antioxidants while giving your digestive system a break from solid food.

Some of the claimed benefits of juice cleanses include:

– Weight loss – By consuming only juices, your calorie intake is dramatically reduced which can lead to quick weight loss. However, much of this initial weight loss is water weight and lean muscle mass rather than fat.

– Toxin removal – Without solid foods, your body can focus energy on flushing out toxins that have built up. However, our bodies already have effective detoxification systems like the liver and kidneys.

– Improved digestion – Resting your digestive system and flooding it with nutrients may allow it to reset and work more efficiently after the cleanse. But extreme low-calorie diets can actually slow digestion.

– Increased energy – The nutrients from cold-pressed juices provide quick energy. But energy crashes can occur from unstable blood sugar levels during a juice fast.

– Improved skin – Hydration and antioxidants may give skin a temporary glow, but skin benefits are unlikely to last.

– Reset eating habits – Following a restrictive cleanse can help break unhealthy eating patterns. But lasting changes require lifestyle adjustments.

Recommended duration for beginners

Most experts agree that shorter juice cleanses are better for first-timers. Here are some general recommendations:

Duration Pros Cons
24-48 hours
  • Provides introduction to juice cleansing
  • Less risk of side effects
  • Easy to fit into a weekend
  • Very little lasting impact or benefits
  • Difficult to deal with hunger
3-5 days
  • Body has time to begin flushing toxins
  • Hunger becomes easier to manage
  • Can reset eating habits
  • Potential for fatigue, headaches, nausea
  • Weight loss is mostly water weight
5-7 days
  • Allows for full detoxification and withdrawal from solid foods
  • More significant weight loss possible
  • Boosts commitment to better diet after cleanse
  • High risk of adverse side effects
  • Can trigger binge eating after cleanse
  • Must closely monitor physical health

As you can see, shorter cleanses of 24-72 hours provide an introduction to juicing with minimal risk while cleanses over 5 days start posing health concerns for beginners. Many experts recommend starting with a 3-5 day cleanse at most.

Preparing for your first juice cleanse

Preparation is key, especially for your first juice cleanse. Here are some tips:

– Ease into it – Start cutting back on caffeine, alcohol, refined sugars/carbs, and processed foods in the days leading up to the cleanse. This helps avoid withdrawal symptoms.

– Make a schedule – Plan out when you will make and drink your juices each day. Split them into 6-8 small servings spaced evenly apart.

– Get supplies – Have a good juicer, reusable bottles, fresh organic produce ready before starting.

– Stock up on variety – Choose a wide array of vegetables and fruits to prevent boredom and nutritional deficits. Examples include kale, spinach, carrots, apples, berries, pineapple, cucumber, celery, ginger, etc.

– Inform others – Tell family and friends you are cleansing so they can support you. Discourage social events involving food/drinks.

– Reduce exercise – Light walking is fine but back off intense workouts that can stress the body.

– Listen to your body – Stay well hydrated and rest when needed. Stop the cleanse if you feel faint, extremely fatigued, or have other concerning symptoms.

Choosing the right juices

Choosing low-sugar juices with a focus on vegetables is important, especially for beginners who may struggle with energy and blood sugar swings. Here are some healthy juice options:

Juice Ingredients Benefits
Green juice Celery, kale, spinach, cucumber, green apple, lemon Alkalizing and detoxifying
Carrot juice Carrots, ginger Vitamin A for skin and eyes
Beet juice Beets, carrots, apple, ginger Blood and liver cleanser
Fruit juice Pineapple, berries, orange, kiwi, lime Quick energy and hydration
Green protein Cucumber, spinach, avocado, banana, almond milk Plant protein and healthy fats

Aim for 80% vegetable juices and no more than 20% fruit juices to prevent blood sugar spikes and crashes. Mint, parsley, lime, and ginger add great flavor. Dilute fruit juices with water or spinach to decrease sugar content.

Supplements and additions for beginners

Some supplements can help counter side effects and nutrient deficiencies during a juice cleanse:

– Probiotics – Help maintain gut health and digestion when not consuming solid foods. Look for broad-spectrum formulas.

– B-complex – Important for energy and brain function as calorie intake is very low on a cleanse.

– L-glutamine – An amino acid that supports muscle and metabolism; prevents protein breakdown.

– Magnesium – Helps regulate electrolytes that become depleted on a fast. Also aids sleep.

– Matcha powder – Gives an energizing boost and important antioxidants without spiking blood sugar.

Other safe additions for beginners include:

– Lemon/lime – Helps balance pH for less acidic juices. Squeeze into juices or water.

– Spices – Ginger, cinnamon, turmeric add flavor and anti-inflammatory benefits.

– Herbal tea – Variety like green, mint, ginger is allowed. Helps satisfy cravings.

– Broth – Sipping vegetable broth provides electrolytes without breaking the fast.

– MCT oil – Helps control hunger and provides quick energy from healthy fats. Add to juices.

Managing hunger and withdrawal

Hunger and withdrawal symptoms are very common during the first few days of a juice cleanse. Here are some tips for beginners:

– Drink juice when hungry – Drinking extra juices helps control hunger and cravings initially. Hunger dissipates for most by day 3-4.

– Distract yourself – Keep busy with work, light exercise, socializing, or hobbies to make the time pass faster.

– Stay positive – Remind yourself why you are cleansing and that it’s only temporary. The first couple days are the hardest.

– Deal with emotions – Cleansing often brings up emotions and cravings. Be prepared to feel irritable, bored, or fatigued at times.

– Get support – Ask friends and family to encourage rather than sabotage your cleanse. Having a cleansing partner helps too.

– Rest and relax – Honor your body’s need for extra sleep and down time. Take hot baths, meditate, and get massages.

– Withdraw slowly – Gradually reintroduce healthy foods over 2-3 days after the cleanse rather than binging.

Safety tips for beginners

It’s important to keep safety in mind when doing a juice cleanse, especially your first time. Here are precautions for beginners:

– Consult a doctor – Make sure a juice cleanse is appropriate if you have any health conditions or take medications.

– Monitor vitals – Watch for dizziness, heart palpitations, inability to stay warm, or other warning signs to stop.

– Avoid intense exercise – Stick to light walking to avoid stressing the body too much when nutrients are very low.

– Supplement if longer than 3-5 days – Take probiotics, vitamins, minerals, protein powder, and superfood powders.

– Check labels for sugar – Avoid fruit-only juices. Veggie juices should have no more than 5-7 grams of sugar per serving.

– Eat if needed – It’s okay to eat something light if you feel faint or unwell. Your health comes first.

– Break the fast if concerned – End your cleanse early rather than trying to push through. You can always try again later.

– Refeed carefully – Go back to solid foods slowly after cleansing. Avoid heavy meals, meat, alcohol initially.

Maximizing cleanse results

Here are some tips for beginners to get the most benefits from their first juice cleanse:

– Keep a journal – Track symptoms, energy, mood, cravings, and goals to optimize future cleanses.

– Take before/after photos – The scale may not budge but cleansings can refine waistline and skin appearance.

– Flush toxins – Take bentonite clay, magnesium salts, lemon water, or try infrared saunas.

– Be prepared – Have a plan for meals, exercise, work, and social activities post-cleanse.

– Develop new habits – Use the momentum to cut out processed foods, eat more produce, reduce eating late night, etc.

– Iterate and improve – Try different juice recipes, durations, supplements each cleanse to find the best formula.

– Listen to your body – Learn your cues for hunger, fullness, energy crashes to create beneficial cleanses.

Ending a juice cleanse

Ending a juice cleanse properly ensures you maintain the benefits. Here are some tips:

– Break it slowly – Add in raw fruits and veggies, then soups and smoothies before resuming normal foods.

– Keep it light – Avoid heavy meats, dairy, greasy foods, and sugar initially which can shock the system.

– Supplement smartly – Take digestive enzymes, probiotics, antioxidants to rebuild gut health after cleansing.

– Stay hydrated – Drink lots of water and herbal tea as you transition back to solid foods.

– Keep nutrients up – Continue eating nutrient dense whole foods rather than empty carbs or junk food.

– Notice after-effects – Expect continued bowel movements, possible headache and fatigue as the body adjusts.

– Don’t overeat – Be mindful not to binge or over-indulge after a cleanse. Your stomach shrinks so smaller portions may fill you.

– Stick with healthy habits – Let your cleanse be a reset point and motivation for maintaining better diet and lifestyle habits.


A 1-2 day juice cleanse provides a simple introduction for beginners but a 3-5 day cleanse is recommended to see meaningful benefits. Be sure to adequately prepare, choose low sugar vegetable juices, supplement where needed, and ease back into food gradually afterwards. While longer cleanses over 5 days start posing more health risks and are not advisable for first-timers. Appropriate precautions, self-monitoring, and ending the fast if issues arise can help beginners undertake a safe, successful first juice cleanse.
