What are the effects of juicing for 3 days?

Juicing has become a popular way for people to detox, lose weight, or jumpstart a healthier diet. While juicing for a few days can provide some benefits, it also comes with some drawbacks to be aware of. In this comprehensive guide, we’ll explore the effects – both good and bad – of juicing for 3 days straight.

What is Juicing?

Juicing involves extracting the nutritious juice from fruits and vegetables, while removing the fiber. This results in an easy-to-consume but nutrient-dense beverage.

A juice cleanse or juice fast typically consists of consuming these fresh juices exclusively for a period of time, ranging from 1 to 7 days. Many people choose to juice for 3 days as a mid-length cleanse.

Potential Benefits of a 3-Day Juice Cleanse

Here are some of the touted benefits of juicing for 3 days:

Weight Loss

By only consuming juices for 3 days, most people will significantly reduce their calorie intake, which can lead to temporary weight loss. However, much of this early weight loss is water weight or lean tissue, which may quickly be regained once you resume your normal diet.

For lasting weight loss results, juicing is most effective when combined with a healthy whole foods diet and active lifestyle.


Many people choose to juice fast for detoxification purposes. By removing processed foods, added sugars, and other unhealthy substances for 3 days, this allows your body to focus its energy on removing accumulated toxins.

Juices are also packed with antioxidants and nutrients that can help support your body’s natural detox systems. Things like dandelion greens, garlic, and lemon support liver function and glutathione production.

Increased Nutrient Intake

Since you are consuming a concentrated form of vegetables and fruits while juicing, this allows you to ingest more nutrients than you would typically eat in a whole foods diet.

Juices are packed with vitamins, minerals, and phytonutrients that can provide a mega-dose of nutrition when juicing. This includes things like vitamin C, potassium, beta-carotene, and more.

Improved Energy

Some people report feeling more energetic when juice fasting. This is likely linked to removing processed foods, caffeine, and other stimulants from your diet.

However, if you feel tired or sluggish while juicing, your body may need more calories for sufficient energy levels. Listen to your body.

Healthier Diet Afterwards

Doing a short juice fast can act as a reset for your tastebuds. After 3 days of no processed foods, sugary snacks, or fatty meals, you may have an appreciation for whole, natural foods.

This “clean slate” can motivate you to continue healthy eating after the juice cleanse. Making juices can also inspire you to create nutritious homemade meals.

Potential Downsides of Juicing for 3 Days

While juicing has benefits, there are also some drawbacks to consider:

Lacks Fiber

Since juicing removes all of the fiber from fruits and vegetables, this can contribute to digestive issues during a juice cleanse. Things like bloating, cramping, and constipation are common.

Fiber is vital for healthy digestion, gut bacteria balance, cholesterol regulation, and more. Make sure to add high fiber foods back into your diet after juicing.

Blood Sugar Spikes

The natural sugars in fruit juices can cause blood sugar spikes when consumed in excess without protein or fat. This can lead to energy crashes later. Those with diabetes or blood sugar regulation issues should take caution.

Loss of Lean Muscle Mass

Consuming a very low calorie diet from only juices can lead to the breakdown of lean muscle mass as your body looks for fuel sources. This can lower your metabolism.

Doing strength training while juicing can help preserve muscle. Adding plant-based proteins like hemp seeds, spirulina, or pea protein to your juices can also help.

Nutrient Deficiencies

While juicing floods your body with many nutrients, there are some vitamins and minerals that may be lacking or deficient in a juice cleanse. This includes protein, fatty acids, vitamin B12, calcium, and others.

Monitoring your nutrient intake and adding supplements if needed is advised, especially for longer juice fasts. Rotating vegetable and fruit juices can help provide a variety of nutrients.

Food Cravings

It’s not uncommon to experience food cravings or feelings of deprivation when you remove solid foods for several days, especially if you are used to snacking frequently or eating large portions. Planning ahead, staying hydrated, and focusing on health goals can help.

Difficulty Digesting Solid Foods Afterward

After 3 days without fiber or much solid food, jumping back into eating normal meals can be challenging for your digestive system. Feeling gassy, bloated, or having loose stools is common.

Easing back into solid foods gradually and including probiotic foods in your diet can help support the transition.

Should You Juice for 3 Days?

While juicing for 3 days can provide some benefits, it also comes with health risks if done incorrectly or excessively. Here are some things to consider:

  • Consult your doctor – Make sure juicing is safe for any medical conditions you may have.
  • Don’t solely juice long-term – Juice cleanses lasting longer than 7 days require medical supervision.
  • Listen to your body – Stop if you feel faint, fatigued, or unwell while juicing.
  • Supplement if needed – Add protein powder or nutrients like calcium if deficient.
  • Ease into solid foods – Reintroduce fiber-rich foods gradually after finishing juice fast.
  • Stay hydrated – Drink water in addition to juices to prevent dehydration.

If you are new to juicing, trying it for 1 to 3 days can be a reasonable starting point to see how your body responds without major risk. Pay attention to how you feel, and be prepared to stop early if you experience adverse effects. Monitoring your energy, digestive symptoms, and hunger cues can help guide if a juice fast works for your body.

Below is a comparison table summarizing some of the key potential pros and cons of juicing for 3 days:

Potential Benefits Potential Drawbacks
Temporary weight loss Loss of lean muscle mass
Detoxification Lack of fiber can cause digestion issues
Floods body with nutrients May become nutrient deficient long-term
Can reset taste buds Food cravings may arise
Increased energy (for some) Difficulty transitioning back to solid foods

Juicing for 3 Days Protocol

If you decide to embark on a 3 day juice cleanse, here are some tips to help you get started:

Pick Your 3 Days

Choose 3 consecutive days where you can devote your time to juicing. Many people start on a Monday to take advantage of the weekend for preparation and recovery. Avoid picking days where you have important work, family, or social commitments that may interfere.

Get Your Supplies

You’ll need a good juicer as well as enough fresh produce to create 3 days of juices. Plan on getting around 15-20 pounds of produce to have variety. Wash and prep your fruits and veggies ahead of time.

Mix Up Your Produce

Try to include a rotating mix of leafy greens, non-starchy veggies, and some fruits in your juices. This provides a diversity of nutrients. Some ingredients to include:

  • Greens: kale, spinach, chard, lettuce, celery
  • Veggies: carrots, beets, cabbage, cucumber, tomatoes
  • Fruits: apples, oranges, grapefruit, berries, pineapple, lemon
  • Herbs: ginger, turmeric, mint, basil

Supplement If Needed

While juicing removes solids, you can supplement your juices with things like collagen, plant-based protein powder, probiotics or vitamin supplements if you become fatigued or feel you aren’t getting a nutrient.

Drink When Hungry

Plan to drink fresh juice when hunger arises, about 5-6 times per day. Listen to your body. Drink until satisfied, not overly full.

Stay Hydrated

Aim for at least 64 ounces of water daily in addition to your juices. Proper hydration is key!

Transitioning Off a Juice Cleanse

Ending your juice fast properly is just as important as starting it. Here are some tips for transitioning back to solid foods:

Introduce Solid Foods Slowly

On day 4, gradually work solid foods back into your diet starting with broth-based soups, cooked grains and steamed veggies. Chew thoroughly.

Include Probiotic Foods

Eat probiotic yogurt, kefir, kimchi or sauerkraut to help repopulate your gut with healthy bacteria.

Stick to Low Fiber Foods Initially

Keep fiber intake around 10 grams daily for the first few days. Too much fiber at once can cause gas or bloating.

Avoid Processed Foods

Stick to whole, nourishing foods as you transition off your cleanse. Processed snacks and meals may be hard on your system.

Consider Continuing Juicing

Regularly making fresh juices can be a great way to boost your nutrient intake and overall diet long after a juice cleanse.


While juicing for 3 days straight allows for a short term influx of nutrients, cleansing, and potential weight loss, it may be difficult to sustain much longer term due to potential nutrient deficiencies, digestion issues, loss of lean mass, and weight regain. Using a 3 day juice cleanse as an occasional reset rather than a prolonged fast can allow you to reap the benefits without as many drawbacks. Pay close attention to your body, go slowly when transitioning back to solids, and consider continuing juicing as part of a balanced, whole foods diet.
