Monodiet diet

The monodiet diet is a popular method of eating only one food for a predefined period of time. It is rare for a monodiet to continue for more than a few days because of its very restrictive nature. More than a weight loss, monodiet detoxification is supposed to lead to detoxification of the body’s organs. This is a controversial regime.

Characteristics of the monodiet:

  • A single food consumed for several hours
  • Can be practiced 3 consecutive days, one day a week or one meal a day
  • The foods most commonly consumed during a monodiet are apples, celery and rice
  • Water and infusions are to be consumed at will

The main principles of the regime

The foods consumed in the monodiet detox diet are generally plants or cereals rich in micronutrients and antioxidants.

How does the monodiet diet work?

The monodiet consists of consuming the same food for three consecutive days. The chosen food can then be consumed at will during these three days. It is recommended to choose the biological versions. Only one food should be chosen so as not to give the digestive system any extra work. Water, tea and herbal teas are also available during this period and it is important to aim for a minimum consumption of 1.5 to 2 litres of liquids per day. It is also best not to be physically active during this period.

How does the monodiet diet lead to weight loss and detoxification?

Monodiets, like “detox” diets, compare the human body to the engine of a car that clogs up over time, accumulates waste and toxins and can cause fatigue, dull complexion and hair, weakened immune systems, digestive problems, etc. The toxins would come from the body itself but also from outside through pollution, drugs, smoking, alcohol, etc. The body would not be able, at some point, to eliminate all this waste and that is why a detoxification cure would be necessary. The liver, kidneys and intestines are the most targeted organs during a “detox” or monodiet treatment. Technically, most foods offered in monodie diets contain nutrients that are very important to health, including fibre, antioxidants, vitamins and minerals. It is important to mention that the human body, and mainly the liver and kidneys, are the key organs in the treatment of the body’s waste. Yes, the body produces waste, but it is taken care of by our organs and is eliminated naturally. The liver participates, among other things, in the formation of urea before its elimination from the body, in the metabolism and elimination of alcohol and drugs with the help of the kidneys, in the degradation of fatty acids, etc. Then, the kidneys are responsible for filtering an individual’s blood in order to eliminate waste products on a daily basis. Did you know that the kidneys filter an individual’s total blood volume more than sixty times a day? There is therefore no need to worry about the quality of our blood if the kidneys are functioning well.

Finally, we realize that the foods offered during a monodiet are foods containing a significant amount of antioxidants. Remember that antioxidants have a role to play in neutralizing free radicals that damage the body. These free radicals are considered as waste produced by the body but would also come from outside through combustion smoke, chemicals, dust, etc.). These compounds with antioxidant properties are vitamin C, vitamin E, selenium and carotenoids. It is therefore perhaps for this reason that the foods offered in a monodiet are also the richest in vitamin C, vitamin E, selenium and carotenoids.

How long does the monodiet detox diet last?

The classic monodiet lasts three consecutive days at the end of which a light diet must be reintroduced; there are also other monodiet formulas that must be carried out one day a week every week of the year or only one meal a day for one week every month. The important thing is to choose a formula that corresponds to your lifestyle to get the most out of it.

Which food to choose during a monodiet?

The most popular foods used in these diets are:

  • Apples
  • Grapes
  • Cherries
  • Fishing
  • Melon
  • Carrot
  • Asparagus
  • Celery
  • Rice
  • Quinoa

Note that water, herbal teas and tea are also available at will during this period of monodiet detoxification.

Food is prohibited

During the three days of the diet, all foods other than the one chosen for consumption at will are prohibited. Some foods such as sweet products, industrial dishes or alcohol will have to be avoided in order to obtain good results.

Similarly, smoking and all sources of external stress should be avoided if the monodiet period is to be truly effective and beneficial.

Recommendations and precautions to be taken

Are there any risks?

Although monodie diets offer healthy foods, it is important to note that on days when such a diet is practiced, calorie intakes are far too low in calories to reach the recommended intakes of vitamins and minerals. The American College of Sports Medicine indicates that women should consume at least 1200 calories per day, and men should consume at least 1800 to cover needs. In addition, a diet containing less than 1600 kcal per day does not seem to achieve the recommended intakes of vitamin C, E, calcium and magnesium. It is therefore not recommended to follow this diet for several days. The weight that will have been lost is mostly water because the body is emptying itself of its glycogen reserves. Depending on the food chosen to make the monodiet, but protein intake is very low or even zero, which can lead to muscle wasting. Unfortunately, the foods most often named in monodiets such as apples, celery, grapes or peaches are included in the list of foods containing the most pesticides.

Finally, it should be noted that our bodies need good fats, proteins, carbohydrates, fibre, vitamins and minerals to function properly. No food contains all these nutrients and that’s why it’s recommended to eat everything. There is also no single food that contains the nine essential amino acids to build the proteins that make up our muscles, nails, hair fibers, etc.

Is this a diet for you?

A monodiet of three consecutive days is not really advisable, whatever your situation. On the other hand, it is much less harmful to practice the monodiet one day a week. For example, on Monday after a weekend rich in hearty meals. In these cases, the body cleans itself more easily and without suffering the potentially dangerous effects of 72 hours of food deprivation.

Is it a diet compatible with sport?

It is generally not advisable to practice intense physical activity on monodiet days, but around these few days of a specific diet, moderate physical activity is always an excellent idea. It also helps the body to function optimally and eliminate toxins.

What to eat after a monodiet to avoid gaining weight?

To preserve all the benefits of this monodiet, it is necessary, when returning to normal, to eat a balanced diet that is rich in vegetables and fruit and low in processed foods. In addition, it is not recommended to eat animal protein and legumes for about three days after the end of the monodiet, as they are more difficult to digest.

A few figures to go further

No well-founded scientific studies have assessed the impact of monodiets. It is guaranteed that weight loss accompanies this type of diet because it is very low in calories. On the other hand, as mentioned above, these regimes mainly lead to a loss of water. In addition, these very low-calorie diets slow down the basic metabolism (energy expended by the body at rest). As a result, weight gain is almost inevitable at the end of the diet when the person starts eating again as before.

Diet: Our opinion

Monod diets are actually drastic, very low-calorie diets that will cause you to lose water. Substances called toxins are eliminated regularly but mainly naturally by our body and more particularly by our liver. No single food or nutrient can act on the liver and help it in its functions. The important thing is to eat a healthy diet every day, rather than eating a single diet a few times a year. Rather than eating three consecutive days of a single diet, it is better to get into the habit of eating less as soon as the body requests it (following end-of-year meals, for example).
