A slag-free diet is a therapeutic diet aimed at cleansing the body in a short time. Let's consider its features, an approximate diet and indications for use.
Indications
The concept of a slag-free diet differs from conventional diets used for weight correction. The main difference is that it allows you to cleanse the body of accumulated toxins and waste, normalize the digestive system and even get rid of cellulite. As a rule, such a diet is prescribed for medical examinations of the abdominal cavity (ultrasound, irrigoscopy, colonoscopy) or before planned surgical interventions.
Such indications for use are related to the fact that the body must get rid of harmful substances as much as possible to obtain a reliable diagnostic picture. In some cases, nutrition is used as a way to unload, to prevent slagging, to eliminate problems with the gastrointestinal tract. The diet can be used without a doctor's prescription, so everyone decides for themselves whether to use it or not, but there are a number of general indications:
- Dangerous environmental situation in the place of residence.
- Frequent overeating, consumption of unhealthy food.
- The diet consists of products with increased amounts of animal fats, starch, and various synthetic additives.
- Bad habits: smoking, alcoholism, etc.
- Passivity and excess body weight.
In addition to the above recommendations, there are a number of symptoms that indicate problems:
- Rapid fatigue and loss of strength, irritability, sleep problems, depression.
- Gastrointestinal disorders, frequent bouts of nausea, constipation.
- Frequent skin rashes, increased dryness or oiliness.
- Deterioration of hair and nails, joint pain.
- Exacerbation of allergic and chronic diseases.
- Dental problems: stomatitis, periodontal disease, caries.
- Cardiovascular and nervous system disorders.
- Increased risk of cancer.
The diet is based on low-calorie nutrition. The diet includes easily digestible and refined products. When broken down, they do not leave residues that complicate digestion. Most often, the therapeutic diet is followed for 3-7 days or more. Scheduled cleansing for preventive purposes can be repeated 1-2 times a month. Some nutritionists claim that with the right approach to food and abundant fluid intake, you can get rid of 3-5 kg of excess weight in 7 days.
Low-slag diet before colonoscopy
Many diagnostic procedures require special preparation. A low-slag diet before a colonoscopy involves restrictions in food for 3-7 days. This allows you to get the most reliable examination results.
Colonoscopy is one of the effective methods of examining the large intestine. It can be used to examine the entire length of the digestive organ and assess its condition. A special probe is used during the procedure.
It is necessary to exclude fatty and fried foods, meat, fresh vegetables and fruits, alcohol, carbonated drinks, confectionery from the diet. Evening meals are contraindicated. Dinner should be 3-4 hours before bedtime and consist of fermented milk products, water or green tea. Easily digestible food prevents the formation of indigestible residues.
As a rule, a diet is prescribed two days before the examination. This makes it possible to bring the body back to normal and increase the informativeness of the diagnostic procedure in identifying or treating diseases.
Slag-free diet before surgery
If there are indications for surgical intervention, the patient must undergo a number of preparatory procedures. A slag-free diet before surgery is included in this complex. Dietary restrictions are necessary to cleanse the intestines so that after the use of anesthesia there are no undesirable reactions in the form of nausea and vomiting. The diet is followed for 3-5 days and stopped 12 hours before the operation. During this period, it is contraindicated to eat any food.
A slag-free diet should consist of:
- Lean meat and fish
- Boiled vegetables
- Porridge
- Biscuits, crackers
The following are prohibited:
- Whole grains and dairy products
- Fresh fruits and vegetables
- Alcohol, carbonated drinks, strong coffee and tea
- Various hot spices
- Vegetable and animal fats
Following these recommendations allows you to minimize the risk of complications. If the patient has violated the low-slag diet or has not followed it at all, this can lead to serious consequences. First of all, this is vomiting under anesthesia - vomit gets into the lungs, complicating the work of doctors. Medical statistics have recorded a number of fatal cases due to this reason. Vomiting attacks complicate the action of anesthetics, so the patient painfully comes out of anesthesia.
Smokers also face difficulties in the preoperative period. Many of them are afraid of the upcoming operation, so they give up the bad habit the day before the operation. This does not affect its outcome in any way, but it has a negative impact on the recovery period. That is why doctors recommend not smoking 7-10 days before the planned surgical intervention. This rule also applies to alcohol. The above recommendations and a low-slag diet are relevant if you prepare for the operation in advance for 1-3 weeks. In emergency cases, the surgeon will not postpone the procedure and wait for the digestive tract to be cleared.
General information sludge-free diet
There are many reasons that cause slagging of the body and various disorders. The essence of the diet is to get rid of accumulated harmful substances, restore the normal functioning of the body and all its systems. Very often it is used to diagnose the gastrointestinal tract. Cleansing nutrition has two options:
- The removal of harmful substances from the body (toxins, slags) is calculated. During the cleansing period, only berries, fruits and purified water are allowed. Any other products are prohibited. The duration of such treatment should not exceed three days.

Before starting it, you must consult with your doctor or nutritionist.

Slag-free diet menu
Initially, the menu of the slag-free diet implied the use of products grown independently, that is, at home in the garden. Such products do not contain harmful substances. It is very difficult to adhere to this rule, so there is a principle by which you can plan your diet. The body is clogged by high-calorie products, so you need to give them up. The menu should consist of healthy and low-calorie food with minimal heat treatment.
A properly composed menu of a slag-free diet allows you to improve your body in a short period of time. The following diet options are suitable for this:
- Based on the refusal to consume prohibited products. This allows achieving a complex cleansing effect. Follow this diet for 3 days. The diet should only include fruits, berries and purified water. You can also eat vegetable soups, light salads from fresh vegetables, natural juices. The following products have a pronounced effect on removing toxins: apples, pears, oranges, grapefruits, carrots, celery, pineapples.
- The second option is longer - up to 14 days. During this period, you can eat protein foods (lean meat and broths, dairy products). Refined foods, hot spices and food additives should be prohibited.
Both options have low caloric content, so they are contraindicated for patients with a weakened body, for children, during pregnancy and lactation. Before carrying it out, it is recommended to consult a doctor and limit physical activity.
Menu for 3 days
A short-term slag-free diet is most often prescribed before diagnostics of the digestive organs or surgery. It allows you to effectively cleanse the intestines and detoxify the body.
Let's look at an approximate menu for 3 days:
1 day
- Breakfast: green tea and a salad of peeled fresh cucumber, herbs with a dressing of lemon juice and sesame seeds.
- Snack: apple and a glass of natural juice.
- Lunch: vegetable soup with carrot and cauliflower broth.
- Snack: a handful of any berries and green tea.
- Dinner: buckwheat with beetroot cutlet.
- Second dinner: banana and green tea.
Day 2
- Breakfast: a handful of berries and green tea.
- Snack: boiled beetroot, grated on a fine grater.

This diet option speeds up digestion, but it is not recommended to stick to it for more than three days. At the end of the diet, it is necessary to exit it correctly so as not to harm the body. The exit should be gradual, that is, every week you need to add a couple of contraindicated products to the diet. It is very important to follow a fractional diet and drink plenty of water.
The slag-free diet is aimed at positive changes not only in well-being, but also in appearance. By following it for 3-10 days, you can lose 3-5 kg of weight, improve the condition of your skin, nails, and hair. This dietary course is quite complex, as it has many limitations, but its results are worth it.
