The Thonon diet advertises with the motto that you can lose up to 10 kilograms in weight in 14 days. The focus of this diet is on a protein-rich diet that reduces sugar to an absolute minimum. This missing sugar animates your body to encourage the fat cells to self-destruct.

The protein-rich diet with meat, fish and eggs should help you lose weight. The fat cells should destroy themselves due to the lack of glucose in the body in order to get the energy the body needs.

The Thonon Diet is strict and radical. Not for the faint of heart and people with a weak immune system. In this article we introduce you to the Thonon Diet and hope that you can get an idea of this diet for yourself.

Quick Overview

  • The Thonon Diet promises you to lose up to 10 kilograms in 14 days.
  • The diet in the Thonon diet is purely protein-rich and no carbohydrates are allowed. The fat cells are supposed to destroy themselves.
  • In the first phase, the number of calories in the Thonon diet is around 600 – 800 calories per day. After the radical diet, 1500-1800 calories are allowed in the stabilization phase.

What is the Thonon Diet?

The Thonon Diet is a diet that promises you can lose up to 10 kilograms in 14 days. It is clear that this is a very radical weight loss. Depending on how much the starting weight is, less will be lost.

The Thonon diet is very similar to a ketogenic diet. Ketogenic diets are diets that are extremely low in carbohydrates. The body only relies on lipid metabolism. Therefore, the motto of a ketogenic diet is “Combat fat with fat”

The way the Thonon Diet works is pretty simple. Only 600 to 800 calories are allowed in a day. That must not be exceeded. For comparison – a morning smoothie bowl with nuts, coconut, flax seeds and berries has around 450 calories.

Those who survived the 14 days can now consume 1500 to 1600 calories per day for the following week. This phase serves to stabilize the weight after the radical Thonon diet.

What you need to know about the Thonon diet

Before we give you tips and tricks on the Thonon diet, we have put together the most important background information on the diet for you.

In the following section we answer the most frequently asked questions about the Thonon diet.

How does the Thonon diet work?

The Thonon diet works like a ketogenic diet variant. This means that the consumption of carbohydrates is reduced to an absolute minimum. It is believed that ingesting carbohydrates can lead to weight gain. Instead of carbohydrates, a lot of protein is consumed. This includes fish, egg and meat.

Due to the lack of glucose in the body due to the lack of carbohydrates, the body begins to destroy its fat cells. This destruction then releases energy that the body would normally have obtained from glucose.

Only 600 to 800 calories are allowed in the Thonon diet per day. Nevertheless, three meals a day are allowed. However, no small snacks may be eaten in between.

The Thonon Diet is a very strict diet. Since the maximum number of calories per day is only 800 calories, it is quite possible to lose a lot. However, this radical weight loss is not really healthy. Especially people with pre-existing illnesses or a weak immune system should rather eat a healthy and balanced diet than follow a radical Thonon diet.

The diet can also have performance implications for athletes who are on the Thonon Diet. The diet reduces exercise performance in activities that depend on the energy systems. This is especially true for athletes involved in high-intensity and short-term activities.

What can you eat on the Thonon diet?

The Thonon Diet has a strict diet plan. The diet plan repeats itself after the first week. This is the only way to ensure maximum success in losing weight.

Coffee or tea are best for breakfast. Both of course without sugar. If that’s not enough, you can also enjoy a small slice of bread with it.

Boiled eggs, spinach, a steak, or vegetables like carrots are ideal for lunch. Fish and chicken are also good.

Dinner includes practically the same food items as lunch. However, you can also have fruit and salad with your meal.

After the diet phase, the stabilization phase follows. In this phase, up to 1500 calories per day are allowed, during which you’re allowed to consume your protein or other supplements which you can easily Order Online and include them in your deit. This is supposed to prevent the yo-yo effect from occurring. The yo-yo effect is the unwanted and rapid weight gain after a radical weight diet.

Can I quickly lose 10 kilograms with the Thonon diet?

How fast you can lose weight is related to your original weight. If you weigh over 100 pounds, you can experience tremendous weight loss with less food. However, if you weigh 70 kilograms or less, 10 kilograms make up a full seventh of your body weight. So it really depends on the origin.

It is clear that the Thonon Diet can help you enormously in losing weight quickly. Drinking plenty of water can also help you to quench your hunger pangs. Water intake is also very important for your body and can help you lose weight.

You should rather avoid alcohol and sweet drinks, because they have a lot of calories.

Like water, exercise can also help you lose weight. Exercising also burns a lot of calories. Swimming is particularly good. The joints are not stressed too much and the body still has to move a lot. This can quickly lead to deficiency symptoms or symptoms. The back is also not stressed when crawling or swimming back.

How big is the difference after the Thonon diet?

Most people who want to go on the Thonon Diet usually feel too fat or uncomfortable in their bodies before the diet. This is why they start the Thonon Diet in the first place. Even mothers like to shed their pounds with this extreme diet some time after giving birth.

After the diet, people of normal weight lost up to 5 kilos on average. The promised 10 kilos are just a bit too much for people of normal weight.

Nevertheless, as already mentioned above, it depends on each individual body. Not every body loses weight at the same rate.

It is undisputed that the before-and-after difference is definitely big. How long the after-condition lasts depends on how well you can control yourself. Often the yo-yo effect occurs with the reduction diets after the diet, which quickly brings the pounds back to the hips.

What Are the side-effects of the Thonon Diet?

The radical Thonon diet also has its dangers. This diet is strongly discouraged for people who are sensitive to a rapid change in diet. In addition, the type of diet in the Thonon diet is very one-sided.

Stomach ache and abdominal pain

Since the body consumes much less fiber than normal with the Thonon diet, the unbalanced diet of the diet can lead to major stomach or intestinal problems. Not only do the complaints in the gastrointestinal tract disturb, but also the feeling of hunger.

Common complaints with the radical Thonon diet include gas and bloating, constipation or diarrhea and stomach pain. If you already suffer from such ailments in advance, you should rather avoid this diet.

Vitamin and mineral deficiency

With the one-sided diet, it is no wonder that the vitamin and mineral deficiency quickly occurs. The vitamins and minerals are very important for the body to make hormones and enzymes. If there are no vitamins, no hormones and enzymes are formed.

In general, it is difficult for the body to remain healthy and perform all functions well in the event of a deficiency. If the body does not get enough energy, it attacks the muscles.

If the muscles are attacked, the energy consumption in the body decreases. Therefore, after the diet, the person will eat more than before and gain weight again. Therefore diets should always be enjoyed with caution.

Hormonal chaos

The one-sided diet in the Thonon diet can quickly lead to a change in the hormone balance. Since the body is not supplied with the same energy substances as usual, the body switches to a stressful situation.

Women in particular experience changes in their cycle in stressful situations. The period can even be absent entirely. The stability of the bones can also be negatively affected. Unstable bones increase the chance of osteoporosis enormously in old age.

Where did the Thonon Diet originally come from?

The Thonon diet has its origin in the French Thonon-les-Bains, a health resort in beautiful France. A patient there was prescribed this diet by a doctor who kept his patient under medical supervision at all times.

This may not mean that you can only diet under medical supervision, but a quick check with your doctor before starting the diet is recommended. The value of only 600-800 calories per day is so far below the normal need for calories that you need a lot of stamina and discipline to follow this diet.

The diet can be done for a week or two. But you shouldn’t take it longer, as your health will otherwise suffer too much from the daily stress.

Does the Thonon Diet have a big yo-yo effect?

The Thonon diet has a great tendency towards a yo-yo effect. The yo-yo effect is the unwanted and rapid weight gain after dieting. With repetitive diets, the body weight moves up and down like a yo-yo and the starting weight is often below the new end weight.

Since the Thonon diet eliminates a lot of calories, the yo-yo effect is also greater at the end of the diet, as you then feel extremely hungry. In order to eradicate the feeling of hunger in the long term, you have to drink a lot and persevere.

Avoiding the yo-yo effect entirely is practically impossible. So that you can keep the yo-yo effect as low as possible, you have to pay attention to a healthy and above all balanced diet. Sweet drinks, white bread or even ready-made products contain many calories that will not fill you up. Therefore you should avoid these and rather eat enough protein.

What are the chances of success with the Thonon Diet?

The chances of success with the Thonon diet are great. The greater the starting weight, the higher the chances of success. Success has to be defined before losing weight. There is short-term and long-term success.

The short-term success of the Thonon diet is guaranteed for almost everyone with a normal weight.

Depending on the initial weight, the results vary from 2 to 10 kilograms of weight loss after 14 days of the Thonon diet.

Long-term success is not guaranteed with the Thonon diet. Short-term successes are often destroyed by the yo-yo effect that occurs shortly after the end of the diet. Some people are even heavier longer after the diet than they were before.

Who can do the Thonon Diet?

The Thonon Diet is suitable for people who are healthy and want to lose weight or define themselves more. Athletes often want to define their bodies. The Thonon diet is also suitable for athletes.
A no-carb diet like the Thonon diet has other positive effects in addition to weight loss. These are:

  • Constant blood sugar level (prevents ravenous hunger)
  • Muscle building and definition
  • Drainage of the body

There are also sick people who are advised to go on a ketogenic diet. However, this is done under medical supervision. If you do without carbohydrates, brain and nervous diseases such as Alzheimer’s, multiple sclerosis or epilepsy can be alleviated somewhat. Not consuming carbohydrates can also be beneficial for cancer cells.

Thonon Diet: Tips & Tricks

So that you can lose weight effectively with the Thonon diet, there are a few tips and tricks that can make it easier for you. In the following section we have presented you with the most common tips and tricks.

Which foods are good for a Thonon diet?

So that your Thonon diet can be as successful as possible, we have found some good drinks, food, vegetables and fruits for you and have compiled them here.


The best drinks are definitely low in calories. The best way to start the morning is with black coffee or tea – but everything without sugar. If you still need some aroma, herbal tea is also good for the morning drink.

At lunchtime you should especially drink water, you can also put a few lemon, cucumber or ginger slices in the water for the aroma to “spice up” the water. Drinking water is very important and healthy throughout the day.

Cold food

In the morning you have a small wholemeal bread roll or a thin slice of normal bread with your tea and coffee, depending on the day. This should not be spread with butter or jam, but eaten without a side dish.

At lunchtime, the best cold dishes are lettuce and tomatoes.

The salad should be eaten with a salad sauce that is as low in calories as possible. Grated carrots are also possible. Carrots go well raw or cooked. However, you should use as little salt as possible during preparation, as the salt stores water in the body.


You can also have a natural yogurt for dinner. This contains important fats and is also low-carb.

Warm food

The best warm dishes on the Thonon diet are boiled eggs, grilled chicken, a steak, or poached fish in broth. Spinach without salt is also popular. You have to be careful with warm dishes so that you don’t cook with too much salt.

Meat, fish and eggs contain a lot of protein, which is very important in a no-carb diet like the Thonon diet.

Vegetables & fruits

The best vegetables are celery, cooked or raw carrots, and fruits as you like. With the fruits you should be careful that you pay close attention to the calories. A banana has many more calories than an apple.

Vegetables are definitely healthy, but if they are too large, they can also cause gas or bowel problems. Therefore, eat smaller portions of vegetables even if you are very hungry.

Stabilization phase

Those who have come through the 14 days of the Thonon diet well are best placed to go into the so-called stabilization phase after the diet. This should avoid the yo-yo effect that often occurs after a diet. For the first week after the Thonon Diet, 1200 to 1500 calories per day are recommended.

The stabilization phase is also no guarantee that the yo-yo effect will not occur. He can enter at any time. In order to lose weight in the long term, one should make sure to have a healthy and balanced diet and exercise a lot.

Is the Thonon Diet suitable for vegetarians and vegans?

The Thonon diet can be carried out both vegetarian and vegan. Vegetarians can replace animal products such as fish, chicken or steak with protein-rich vegetable products such as avocado, tofu, etc. There are also vegetable steaks or “meatballs” that taste very similar to meat, but are purely vegetable.

Vegans tend to be very healthy people who take care of their bodies. They smoke less, drink less alcohol and exercise a lot.

But this does not mean that you cannot eat an unhealthy vegan diet. The Thonon diet is therefore also easy to do vegan.

Summary: Thonon Diet

The Thonon diet is not really healthy for the body and the psyche. However, if you want to lose weight quickly, and your body is healthy and fit, the diet can be worthwhile because it is really effective. If you are looking for a long-term improvement for your body, it is definitely worthwhile to pursue a healthy and balanced diet with sufficient exercise in the long term.

The extreme diet can bring your body completely out of balance and the stabilization phase is also rather questionable. The diet can put you in a bad mood, discomfort, cravings and cravings. A lot of sport, a lot of water and a lot of exercise are a better solution in the long run.
