You've probably heard of juice cleanses. They're those trendy juice diets where you swap solid food for a few days of nothing but fruit and vegetable juices for their promise of weight loss, better skin, a clearer head, a boost of energy, and a deep clean for your body. 

Some people swear by the juice cleanse power, saying they feel lighter, clearer-headed, and have better skin. They believe the juices give their digestive system a break and flood their bodies with nutrients. Many people think a 7-day juice cleanse can "detox" your body, but while it can have some benefits, they're not for everyone. 

Going on a juice cleanse for too long can leave you feeling weak and out of balance. And if you have any health problems, you might want to think twice before trying one.

So, is a juice cleanse a healthy choice? Let's take a closer look at the pros and cons before giving it a go. 

Health Benefits of a Juice Cleanse Diet  

A juice cleanse diet has gained popularity as a means of consuming concentrated nutrients and supporting digestive health. By replacing solid food with a regimen of fruit and vegetable juices, individuals aim to provide their bodies with a break from digestion while replenishing essential vitamins, minerals, and antioxidants. 

Below, we provide a comprehensive understanding of the potential advantages and risks of a juice-cleanse diet, drawing upon research and case studies to offer a balanced view.

1. Digestive System Reset & Gut Health

Have you ever felt like your digestive system needed a vacation? Juice cleansing can give it just that! By giving your digestive system a break from solid foods, detox diets and juice diets can help reduce bloating and promote smoother digestion.

However, while fresh juice detox diets provide essential vitamins and minerals, they contain very little fibre since juicing removes most of it. This lack of fibre means your gut bacteria aren’t getting the usual benefits from whole fruits and vegetables.  

Instead, the focus shifts to the fast absorption of nutrients, which can still offer a temporary sense of lightness and energy. For gut health, it's essential to balance juicing with fibre-rich meals outside of the cleanse.

According to the study of Yoon Jin Choi from the Department of Internal Medicine, Seoul National University Bundang Hospital, et al., drinking fruit and vegetable juice within short-term period improved the variety of good bacteria in the gut and increased the amount of a specific type of helpful bacteria called Faecalibacterium. This healthy diet could help reduce digestive issues and feelings of tiredness. 

If you're looking for a convenient way to support your gut health during a cleanse, Presscription's Gut Health Juice is a great option. It's packed with ingredients like ginger, which can help reduce inflammation, and lemon, which can boost your digestive enzymes.

2. Increased Energy Levels and Vitality

A 3-day juice cleanse can give you an energy boost, thanks to the vitamins and minerals that help your body convert food into fuel more efficiently. The natural sugars in fruits and vegetables provide a quick energy lift without the crash associated with processed sugars. 

While the lack of fibre might leave some feeling lighter, the fast absorption of nutrients can temporarily increase energy and vitality. However, it’s important to maintain balance with solid foods for sustained energy in the long term. Cold-pressed juices are a great way to reset, but they work best as part of a balanced diet. 

Presscription's Active Cleanse is packed with these essential nutrients from fresh, organic produce and raw juice. It is designed to provide the extra fuel you need to power through your workouts and stay energised all day long.  

3. Metabolic Boost & Weight Loss 

One of the most advertised benefits of juicing is that it can help you lose weight. By replacing regular meals with low-calorie juice diets, people can create a calorie deficit, attaining how much weight they achieve to lose. Additionally, juice cleanse may boost metabolism, particularly when juices contain ingredients like cayenne pepper and lemon, known to have thermogenic properties.  

Based on the study of Susanne M. Henning from the Center for Human Nutrition et al., a 3-day juice cleanse altered gut bacteria in a manner that supports weight loss, elevated nitric oxide levels—which help relax blood vessels—and reduce fat breakdown in the body.

4. Clearer Skin

Juice cleanses aren't just good for your insides; they can also work wonders for your skin. The antioxidants in fruits and vegetables like carrots and beets are like tiny superheroes, fighting off free radicals that can cause premature ageing and wrinkles. It's like giving your skin a shield against the elements.

Hydrating ingredients in your diet, like cucumber, are like a refreshing splash of water for your skin. They can help reduce puffiness and give your face a plump, healthy look. And let's not forget about vitamin C from oranges. This powerful nutrient helps boost collagen production, which is essential for keeping your skin firm and elastic. 

According to Vivien W. Fam, PhD, RDN from Zen Dermatology, Sacramento, California, consuming fruits and vegetables, nuts, legumes, and polyphenolic beverages can improve skin health, including hydration, hyperpigmentation, wrinkles, erythema, collagen, and elasticity. During a juice cleanse, these nutrient-rich ingredients are concentrated into easily absorbable liquids, allowing the body to quickly take in antioxidants and vitamins that support overall skin health.

5. Improved Mental Clarity & Cognitive Function

Many people say they feel sharper and more focused after doing a juice cleanse. This might be because juice cleanses help you cut down on processed foods, which can make you feel foggy. 

Plus, raw juices are packed with brain-boosting nutrients like antioxidants and omega-3 fatty acids. Ingredients like blueberries and spinach are known to help improve your thinking skills and protect your brain from damage. They can help you think more clearly and improve your mental performance. 

According to Sanjiv Agarwal's case study from NutriScience LLC, East Norriton, PA 19403, USA, et al., while drinking fruit juice regularly may not significantly improve all aspects of cognitive function, it can positively impact mental health. 

Specifically, the study found that fruit juice consumers experienced fewer days of anxiety compared to non-consumers. This suggests that the nutrients in fruit juice, which are concentrated in juice cleanses, could potentially contribute to improved mental clarity and overall well-being.

What Are the Risks of Juice Cleansing? 

While juice cleanses can be a refreshing, healthy lifestyle/diet for getting a boost of nutrients, they're not a magic bullet. In fact, there are some downsides to consider.

If you're only drinking juice for days on end as your regular diet, you might miss out on important stuff like protein, dietary fibre, and healthy fats. These are essential for building and maintaining muscle, keeping your immune system strong, and feeling your best. 

Too much juice (fruits/vegetables) in your diet can lead to some digestive drama. You might experience diarrhoea because there's not enough fibre to keep things moving smoothly. Plus, all that liquid can throw off your electrolytes, leaving you feeling dehydrated and tired. 

If you go back to your old eating habits after long periods of juice fast, you might see the weight come back on due to excessive hunger pangs. It's like hitting the reset button on your diet, and if you don't make some changes to your physical activity and real nutrition, you might end up right back where you started, affecting your general health and skin condition.  

Potential Risks of Juice Cleanses

• Nutritional Deficiencies: Overly relying on juice cleanses without incorporating solid foods can lead to nutritional deficiencies and potential health issues. While juice cleanses can provide a concentrated dose of nutrients, they are not a complete meal replacement. Unlike whole fruits and vegetables, juices often lack essential macronutrients like protein, fibre, and healthy fats. 

• Blood Sugar Fluctuations: Based on Tamaeh Monteiro-Alfredo of Coimbra Institute of Clinical and Biomedical Research (iCBR) et al., fruit juices are packed with natural sugars, which can send your blood sugar soaring. This can lead to energy crashes and other problems, especially if you have diabetes or pre-diabetes. It's like a rollercoaster ride for your blood sugar levels, and that's not good.

• Digestive Discomfort: Too much juice can lead to some digestive discomfort. You might experience diarrhoea because there's insufficient fibre to keep things moving smoothly. Plus, all that liquid can throw off your electrolytes, leaving you feeling dehydrated and tired.

• Rebound Weight Gain: After a juice cleanse, if you go back to your old eating habits, you might see the weight come back on. Rebound weight gain after a juice cleanse can be due to slowed metabolism, muscle loss, and a lack of sustainable lifestyle changes. The weight lost during a cleanse is primarily water weight, and it may not reflect significant fat loss. Adopting sustainable lifestyle changes is crucial for the success of any weight loss program.

So, what's the bottom line? Juice cleanse can be a fun and refreshing way to kick start a boost of nutrients, but they're not a long-term solution. It's important to balance them with a healthy, well-rounded diet and to be aware of the potential risks. 

Key Takeaways 

Juice cleanses can offer many health benefits. It can improve digestion, provide weight loss, have clearer skin, and mental clarity, and increase energy. However, these benefits are not long-lasting, and juice cleanses are not suitable for everyone.
