The ultimate guide to the gut cleanse

In general, anyone can do a gut cleanse as long as there are no serious gastrointestinal diseases or digestive disorders. If you're unsure, you can always ask the doctor or nutrition expert you trust. People with chronic conditions and pregnant women in particular should only do a gut cleanse under medical supervision. People with histamine intolerance or an intolerance to certain foods should also talk to a doctor before cleansing their gut at home.

The ideal duration and frequency of your gut cleanse depends on various factors. These include how much strain your gut is under, your complaints and how your cleanse goes. A gut cleanse can take several weeks in total. The frank. gut cleanse as a kick-start to your gut cleansing lasts 3, 5 or 7 days, as you prefer. The supplements it contains keep you supplied for several weeks.

Ideally, one single gut cleanse is enough for you. By adjusting your lifestyle you can keep this ideal state. If you need several courses of antibiotics, though, it may still make sense to do another gut cleanse.

A gut cleanse is generally a safe way to improve gut health. However, side effects can occur if you overlook certain things or if your gut has been badly affected, though these are usually mild and temporary. Possible side effects include:

• temporary worsening of symptoms such as bloating, diarrhoea or constipation
• temporary drop in energy or mood swings
• temporary headaches or dizziness
• temporary skin reactions such as acne or rashes

Keep in mind that side effects can vary and also depend on the type and intensity of the gut cleanse. People with serious gastrointestinal diseases or who are pregnant should consult a doctor before doing a gut cleanse. It's also important to note that a gut cleanse should not be seen as a substitute for medical treatment of digestive tract conditions.

Digestive problems often occur when the gut microbiome is not intact and cause a lot of distress for those affected, even to the point of shutting themselves away at home. They can include various symptoms, such as diarrhoea, constipation, stomach ache and nausea. These symptoms can be caused by a variety of factors, including the type and amount of food eaten, stress, disturbed gut flora, or several factors at once.

Bloated belly and gas

Your belly can be bloated for several reasons. The technical term is meteorism. If you're distracted while eating, you can swallow more air without noticing, and it collects in the digestive tract. The bacteria in the gut also break down food components, which can produce gas. Certain foods such as pulses, cabbage, onions and garlic can lead to increased gas. Whatever the cause, the gas can stretch the gut and cause pain. When it escapes again, it can lead to uncomfortable wind, known as flatulence.

Food intolerances and nutrient deficiency

A disturbed gut microbiome can mean the resident germs no longer make use of food components as well, so it is more likely that certain foods are no longer tolerated. On top of that, a gut microbiome that isn't working properly makes nutrient deficiencies more likely.

Did you know that gut flora is connected to the brain and can therefore also influence our mind? Via the so-called gut-brain axis, the brain sends information to the gut and vice versa. This means gut flora can influence hormone levels. For example, an imbalance of bacterial strains is linked to mood disorders such as anxiety and depression. Here, though, science is still at the beginning!

Tiredness and lack of energy can be caused by various factors, such as stress, lack of sleep, an unhealthy diet and too little exercise. A disturbed gut microbiome can also have a negative effect on your energy levels. Here we explain different symptoms:

Sleepiness, weakness and slower reaction time

You've just got up and already want to go back to bed? You feel like you're never properly awake? You react much more slowly than usual? Constant sleepiness, always feeling tired and slower reactions can be signs of low energy.

Lack of drive

You're dodging sport even though you were looking forward to it, and would rather stay on the sofa? A lack of motivation and energy can be signs of low energy.

Trouble concentrating

You find it hard to concentrate and your thoughts often wander off? Trouble concentrating can also point to low energy.

Sleep problems

You have trouble falling asleep or staying asleep? That can point to low energy too!

Acne

Acne is a common condition caused by inflamed sebaceous glands in the skin and often appears on the face, back and chest. Studies have suggested that disturbed gut flora can raise the risk of acne. Poor gut health can promote inflammation in the body, which can lead to skin problems.

Eczema

Eczema is a skin condition marked by inflammatory reactions of the skin. Symptoms can include redness, flaking, itching and blistering. An imbalance of gut flora can mean the body doesn't absorb certain nutrients that are important for your skin. A lack of these nutrients can raise the risk of eczema.

Psoriasis

Psoriasis is a chronic autoimmune condition that leads to an overproduction of skin cells and shows up as silvery, scaly patches on the skin. There are indications that disturbed gut flora can raise the risk of psoriasis. Healthy gut flora can help reduce inflammation in the body, which may lower the risk of psoriasis.

Rosacea

Rosacea is a skin condition marked by redness and inflammation of the skin on the face, especially on the cheeks, nose, chin and forehead. A disturbed gut microbiome can raise the risk of inflammation in the body, which in turn can raise the risk of rosacea. Healthy gut flora can help reduce inflammation and lower the risk of rosacea.

Skin rashes

Skin rashes can be caused by various factors such as infections, allergic reactions or contact with irritants. Disturbed gut flora can also lead to allergic reactions, which can cause rashes and itching.

Allergies are overreactions of the immune system to normally harmless substances, such as pollen or food. In an allergic reaction the body produces antibodies against these substances and releases histamine, which can lead to a range of symptoms, such as skin rashes, swelling or digestive problems.

The gut plays an important role in how allergies develop, as it is part of the immune system and closely linked to the body's whole immune system. Disturbed gut flora can raise the risk of developing allergies, as it impairs the barrier function of the gut ("leaky gut") and activates the immune system unnecessarily.

A disturbed gut microbiome can also affect body weight, both in the form of weight gain and weight loss. This is because the gut microbiome influences digestion and the absorption of nutrients and can regulate hormones. These include leptin and ghrelin, which influence your feelings of hunger and fullness. Keep in mind, though, that being overweight has complex causes, so healthy gut flora alone does not lead to a healthy body weight and can only be seen as part of a holistic approach.

Weight gain

Some studies have suggested that unhealthy gut flora can be linked to a higher body mass index (BMI) and a higher risk of being overweight and obese. For example, certain bacterial strains can influence the absorption of fatty acids and the production of hormones that regulate feelings of hunger and fullness.

Disrupted nutrient absorption

Gut flora plays an important role in the work of your gastrointestinal tract and in absorbing nutrients from food. If the balance of the gut microbiome is disturbed, nutrients may be absorbed less well. More short-chain fatty acids (SCFAs) can also be produced, which serve as an energy source for gut cells and can reduce inflammation. These fatty acids can also regulate feelings of hunger and fullness by influencing the release of hormones involved in regulating appetite.

Change in digestion speed

A disturbed gut microbiome can change the speed of digestion, which can mean food passes through the digestive tract more slowly or more quickly. If digestion is too fast, the body may not absorb enough nutrients and the person may feel they need to eat more.

Raised inflammation levels

A disturbed gut microbiome can promote inflammation in the body, which in turn can raise the risk of insulin resistance. Insulin resistance can affect metabolism and lead to weight gain.

Change in hormone balance

A disturbed gut microbiome can also affect hormone balance, especially the hunger and fullness hormones leptin and ghrelin.

Weight loss

A disturbed gut microbiome can mean the body absorbs fewer calories from food and so may contribute to weight loss. Disturbed gut flora can also lead to impaired insulin sensitivity and inflammation in the body, which can slow metabolism and raise the risk of obesity.

A permeable intestinal barrier ("leaky gut") can lead to chronic, low-grade inflammation in the body, which is associated with a higher risk of chronic conditions such as type 2 diabetes, cardiovascular disease and cancer.

What shouldn't you forget during your gut cleanse? Here are the most important components:

Cleanse: Choose the fasting cleanse that's best for you. Frank. offers a big selection of different cleanses so you're sure to find the right one. If you have questions, you can always contact customer support at info@thefrankjuice.com.

Gentle laxative: If you want to start your fasting cleanse with an enema, you need a laxative for it. Depending on your preferences there are different products with different mechanisms of action: osmotic or gut-stimulating laxatives, bulking agents, swelling agents or lubricants.

Probiotics: Probiotics are live bacterial strains that can help restore the balance of gut flora. You find them in fermented foods like yoghurt and kefir. In high doses and in a well-tolerated form they are also available as supplements.

Prebiotics: Prebiotics are food components that promote the growth of beneficial bacteria in the gut. Fibre is found in foods like wholegrain products, fruit and vegetables. Here too you can turn to supplements.

Diet: Besides prebiotics and probiotics, a balanced diet in general plays a big role in your gut cleanse. Go for nutrient-rich foods to build up healthy gut flora. If you need inspiration for tasty, easy and gut-friendly dishes, check out our frank. guides!

Relaxation, sleep and exercise: Not only your diet, but also your stress level, how long and how well you sleep and how much you move all affect your digestion. It's best to make a plan for how you want to work these things into your everyday life from now on.

Eliminating waste: The gut is responsible for eliminating waste from the body, including toxins and metabolic waste. If the gut isn't working properly, this waste can stay in the body and lead to health problems.

Absorbing nutrients: Healthy gut flora supports the absorption of nutrients from food, including important nutrients like vitamins, minerals and antioxidants. These nutrients play an important role in the body's natural cleansing processes and in protecting it from toxins and pollutants.

Binding toxins: Gut flora can bind and neutralise certain toxins before they enter the bloodstream and can cause harm in the body. These toxins are then excreted in the stool.

Producing short-chain fatty acids: Healthy bacteria in the gut produce short-chain fatty acids such as butyrate, which support the gut lining and promote the growth of healthy germs. This may help improve the body's natural cleansing capacity.

During a gut cleanse the gut can work especially effectively, as the fasting cleanse combined with prebiotics and probiotics, as well as a long-term change of diet, can help move metabolic end products and toxins out of the body. The gut cleanse can help promote the growth of healthy gut bacteria and reduce harmful germs that may be responsible for inflammation and toxin formation in the gut.

By supporting the gut's immune system and strengthening the gut lining, toxins and heavy metals taken in through food can also be neutralised and excreted after the gut cleanse, before the body absorbs them.

It's important to note, though, that a gut cleanse alone is not enough to rid the body of all toxins. A healthy diet, regular sweating through strenuous exercise, enough sleep and avoiding harmful substances like alcohol and tobacco are also important to improve the body's natural cleansing capacity.

Probiotics: Probiotics are beneficial bacteria that can help restore the balance of gut flora.

Prebiotics: Prebiotics are special fibres that serve as food for the beneficial, health-promoting bacteria in the gut and can promote their growth. The stronger the good bacteria are, the less room there is in your gut for harmful bacterial strains.

Digestive enzymes: Digestive enzymes can help extract nutrients from food and support the work of your gastrointestinal tract.

Micronutrients: During a gut cleanse it can be useful to supplement certain nutrients such as omega-3 fatty acids, vitamin D and magnesium to support optimal health.

That's why the frank. gut cleanse contains both prebiotics and probiotics with further functional additions, such as magnesium citrate.

Regular exercise isn't just good for you in general, it also has a positive effect on your digestion. Studies have suggested that exercise may reduce the risk of bowel cancer and improve gut function. If you move regularly, you also kick-start your metabolism, which in turn supports your gastrointestinal tract. Right during and after exercise, your gut movements are stimulated, which supports the elimination of waste products from the body.

Exercise can also reduce your stress, which can have a negative effect on gut health. Stress can change your gut flora, which in turn can cause digestive problems and other complaints. With exercise and relaxation practices like yoga or meditation you can reduce stress effectively.

A healthy gut can help reduce stress and, the other way round, stress can affect the gut negatively. The gut and the brain are in constant interaction and together form the so-called gut-brain system. This connection is so close that the gut is often called the "second brain".

Everyday stress can affect your gut function and change your gut flora, which can cause digestive problems like diarrhoea or constipation and also inflammation in the gut. Conversely, disturbed gut flora can also cause stress and may raise the risk of anxiety and depression.

A healthy gut can have a positive influence on sleep, as the gut and the brain are closely connected and the gut-brain system plays an important role in regulating the sleep-wake rhythm.

Disturbed gut flora or digestive problems like heartburn, diarrhoea or constipation can affect sleep and lead to sleep problems. In addition, inflammation in the gut can also lead to a rise in inflammatory substances in the body, which in turn can affect sleep.

If you go back to your old way of eating after the gut cleanse, the state of your gastrointestinal tract can get worse again. That's why your change of diet should always be one that you're happy with in the long term and that tastes good to you! With every meal, make sure you have a portion of vegetables and choose wholegrain over white flour.

Eating too many ultra-processed foods can promote the growth of pathogenic bacteria because of their high content of refined sugar and additives and too little fibre.

Using antibiotics when they aren't needed can damage gut flora and promote the growth of pathogenic bacteria.

Stress and lack of sleep can have a negative effect by inhibiting the growth of beneficial gut bacteria and promoting the growth of pathogenic bacteria.
