10-Day Juice Diet: Weight Loss Results, Benefits, and Risks

Juice diets have surged in popularity, promising rapid weight loss, detoxification, and a host of other health benefits. These programs often involve replacing meals with fruit and vegetable juices for a period ranging from three to ten days. But are these claims supported by scientific evidence, and are juice diets a safe and sustainable approach to weight loss?

What is a Juice Diet?

Whether labeled as a juice fast, cleanse, or detox, all juice diets center around consuming fruits and vegetables in their liquid form. Many juice diets require abstaining from other foods and only drinking juice, while some allow certain solid foods in conjunction with juices. Calorie intake is typically very restrictive, with the most extreme juice diets limited to a short period, usually between three days and one week. Juice diets that permit some solid foods and more calories are sometimes followed for a longer duration. Juice-only diets are usually vegetarian and can also be vegan, although some plans allow the addition of honey or yogurt to the juice.

Popular Juice Cleanse Programs

Several juice cleanse programs are available, each boasting unique offerings such as organic ingredients, added protein options, or a focus on convenience. These programs include different juices made from a mix of fruits and veggies, like beetroot and celery, and functional ingredients, such as apple cider vinegar and cayenne. Some of the most well-known juice cleanse programs available are:

  • Raw Generation: Offers a variety of juice cleanse programs marketed for weight loss, detoxing, and other goals. Their juices are cold-pressed and flash-frozen to preserve nutrients. Popular cleanses include the Skinny Cleanse, which includes cold-pressed juices made with apples, carrots, limes, ginger, and other fruits and veggies. Raw Generation also has the Protein Cleanse, which has you consuming just 38 grams of protein in the entire day. Cleanse pricing starts at $135 for a three-day cleanse, $200 for a five-day, $270 for a seven-day, and $370 for a 10-day program.
  • Suja Organic: Known for its USDA-certified organic juices and lower-sugar options. Their three-day and seven-day Suja Organic Juice Cleanse includes a mix of green juices and citrus blends. Suja also offers a more flexible approach with cleanses that allow some whole foods alongside the juices-the brand recommends starting the day with a hearty breakfast. Both the three-day and seven-day cleanses are priced the same, at $120.
  • Pressed Juicery: A popular choice for convenient, grab-and-go cleanses. Their Cleanse 1, 2, and 3 options cater to different experience levels, from beginners to advanced. One-day cleanses are $35, three-day cleanses are $105, five-day cleanses are $175, and seven-day cleanses are $245. Pressed Juicery also offers wellness shots marketed for immune support, gut health, and more.
  • Juice From the RAW: Sells cold-pressed, raw juices with no preservatives. It offers juice cleanse programs for two, three, five, six, nine, and ten days. The intermediate 2-Day Juice Cleanse with Probiotics costs around $98, while the six-day cleanse costs $220. Juice From the RAW juices are delivered frozen, and they can last in the freezer for up to six months. Just defrost them at room temperature the day before you start your cleanse.

Potential Benefits of Juice Cleanses

While juice cleanses are often promoted with a range of health claims, it's important to examine the potential benefits with a critical eye, considering the available scientific evidence.

  • Increased Nutrient Intake: Fruit juices are a source of antioxidants, potassium, and vitamin C. These beneficial plant compounds might help lower blood pressure, research shows. However, juice cleanses lack fiber that's found in whole fruit. And you can get all these nutrients plus fiber by eating whole fruit.
  • Hydration: Many people don’t drink enough water daily. Juice cleanses provide good hydration and may help prevent symptoms of dehydration, such as brain fog, irritability, and headaches. However, some of these symptoms can also result from not getting enough calories and feeling hungry.
  • Short-Term Weight Loss: Some studies suggest that juice-only diets can lead to short-term weight loss and alter gut bacteria. However, these studies often involve very low-calorie intake, and the weight loss may be primarily due to calorie restriction. It's important to note that people usually regain the weight they lost after stopping the juice cleanse.

Potential Risks and Considerations

Despite the potential benefits, juice cleanses also carry several risks and considerations that individuals should be aware of before embarking on such a diet.

  • Lack of Scientific Evidence: Despite claims about detoxification, very limited scientific evidence supports juice cleanses. The body already has an efficient detox system - the liver and kidneys - that filters toxins from the body, deeming any extra "cleansing" unnecessary. While some studies suggest short-term benefits, there’s little proof that juice cleanses provide lasting health improvements. What's more, we currently don't have solid research on detox programs' long-term effects.
  • Blood Sugar Spikes: Many juices contain high amounts of natural sugars from fruits. Without fiber to slow digestion, sugar enters the bloodstream quickly, causing glucose levels to spike and then crash. This can lead to dizziness, fatigue, and irritability, especially for people with diabetes or insulin resistance.
  • Disrupted Gut Health: Juicing may mess with the microbiome. A Northwestern study compared three diet groups: those who drank fruit juice only, those who consumed juice with solid foods, and those who ate whole plant-based foods. The group that did a 3-day juice cleanse showed the most harmful gut bacteria changes linked to inflammation, while the group that ate whole foods saw more beneficial shifts. The juice-plus-food group had milder effects.
  • Kidney Issues: People with kidney issues who are prescribed to limit their oxalate intake may want to skip juicing. One case study in the American Journal of Medicine found that a man with stage 3 chronic kidney who had been on an unusually long (six-week) juicing program ended up consuming too much oxalate. Juices seem to boost oxalate absorption because they tend to be low in calcium and high in vitamin C.
  • Unsustainable Weight Loss: Severe caloric restriction is not sustainable for most people and rarely leads to long-term weight loss. It may also increase a person’s risk of other complications. In most cases, a person will return to their starting weight quickly once caloric restriction ends.
  • Low Blood Sugar: Consuming an insufficient number of calories can cause a person to experience symptoms relating to low blood sugar, including fainting, weakness, dehydration, headaches, and hunger.
  • Malnutrition: A person on a juice cleanse may not consume enough proteins or fats. Both of these are crucial to physical health, healing, and brain function. Eliminating food groups for extended periods may also lead to malnourishment.
  • Dehydration: If a juice cleanse includes laxatives or other methods of bowel stimulation, a person could lose too many nutrients in their stool. This can lead to dehydration and imbalanced electrolytes.

How to Do a Juice Cleanse Safely

If you're still keen on trying a juice cleanse, take a few precautions to help avoid fatigue, blood sugar crashes, or nutrient deficiencies. If you have any health conditions, always check with a healthcare professional, like a dietitian, before starting. Juice cleanses aren’t for everyone, especially those with health conditions such as diabetes, digestive disorders, or nutrient deficiencies.

Here are some tips to keep a juice fast safe and balanced:

  • Keep it short: Stick to a cleanse of one to three days. Longer cleanses can lead to low energy, irritability, and hunger. Your body doesn’t need weeks of liquid-only meals to "reset."
  • Choose low-sugar juices: To avoid blood sugar spikes, go for juices with plenty of veggies and some fiber. Many juices made for juice cleanses contain natural sugars from the fruit, but you'll also want to check the nutrition facts label and avoid juices that contain added sugar.
  • Don’t skip protein and fiber: Add small amounts of plant-based protein (like vegan protein powder) and fiber (like blended veggies) to keep your energy stable and support digestion.
  • Listen to your body: If you feel dizzy, weak, or extremely hungry, it’s OK to quit. Eating nutrient-dense whole foods - like nuts, avocados, veggies, and lean proteins such as fish and poultry - can help you feel better.

Alternatives to Juice Cleanses

For those seeking sustainable weight loss and overall wellness, there are several alternatives to juice cleanses that are supported by scientific evidence and promote long-term health.

  • Balanced Diet: Eating a balanced diet and staying adequately hydrated are the best ways to maintain a healthy weight and support the body’s removal of toxins. A balanced diet includes a variety of fruits, vegetables, whole grains, lean proteins, and healthy fats.
  • Plant-Based Diets: Based on minimally processed foods, these diets are naturally rich in fruit and vegetables and are associated with reduced body weight. With good planning, a plant-based diet can provide all the nutrients necessary for good health.
  • Intermittent Fasting: This involves abstaining from eating for limited periods and eating a regular diet at other times. Reviews have linked intermittent fasting with weight loss and improvements in insulin sensitivity.

A Personal Experience with a 10-Day Detox

One individual shared their experience with a 10-day detox program called "The Blood Sugar Solution 10-Day Detox," designed by Dr. Mark Hyman. This program aimed to eliminate foods, drinks, and habits associated with spiking blood sugar. The individual followed a plant-based, vegan diet and avoided gluten for digestive reasons.

During the detox, they experienced several positive changes, including clearer skin, improved sleep, reduced digestive issues and bloating, and a slight weight loss. They were allowed to eat three meals a day with snacks in between, following a detailed menu provided by Dr. Hyman. The detox also involved eliminating grains, sugar, and natural sweets and starches.

The individual also took supplements, including omega-3, Vitamin D, Vitamin B-12, and magnesium. They also eliminated caffeine and alcohol. One of the best aspects of the plan was taking a relaxing bath infused with baking soda and Epsom salts every night. They were also instructed to journal every night, answering prompt questions to go with the theme of each day.
