The Dukan Diet is a low-carb, high-protein diet created by French doctor Pierre Dukan. It involves four phases, two for weight loss and two for weight maintenance. The first phase is the most restrictive, with a diet of only protein and some fat, while the second phase alternates days of protein with days of protein and non-starchy vegetables. The third phase reintroduces some foods, and the fourth phase is indefinite, with a generally healthy diet and one all-protein day a week. The Dukan Diet is controversial, with some people regaining weight after stopping the diet, and some health professionals criticising it for promoting an unbalanced way of eating. The diet may put your body into ketosis, where you burn fat for energy instead of carbohydrates, but this can cause side effects such as nausea, vomiting, tiredness and diarrhoea.

The Dukan Diet is a low-carb, high-protein diet
The Dukan Diet is a controversial weight-loss plan that has been criticised by health professionals for promoting an unbalanced way of eating. The diet is considered to be excessively restrictive, with the first two phases cutting out most food groups, including fruits and vegetables, which can lead to nutritional gaps and deficiencies in important nutrients such as vitamin C and folate. The diet also eliminates healthy sources of fibre, such as avocados and nuts, because they are considered too high in fat. This can negatively affect digestive health and gut health, and may cause constipation.
The Dukan Diet is different from the keto diet as it has stages and reintroduces carbs, whereas keto is a high-fat, moderate-protein diet. The early phases of the Dukan Diet may promote ketosis, where your body burns fat instead of carbohydrates, but later phases allow for higher quantities of carbs than keto, so it is unlikely that ketosis will be maintained.
The Dukan Diet is free to follow, although you will need to purchase oat bran, which is recommended as a source of fibre. However, oat bran is not particularly high in fibre, and most people need more than it provides. The diet can also be hard to stick to due to its restrictive nature, and the lack of carbs may make you more tired than usual as you need carbs for energy.

The diet has four phases, two for weight loss and two for maintenance
The Dukan Diet is a low-carb, high-protein diet that is divided into four phases, two for weight loss and two for maintenance. The diet starts by calculating your goal weight, or "true weight", based on your age, weight loss history, and other factors. The four phases are:
- Attack phase (1-7 days): This phase involves eating unlimited lean protein and 1.5 tablespoons of oat bran per day.
- Cruise phase (1-12 months): Alternating days of lean protein and non-starchy vegetables, plus 2 tablespoons of oat bran.
- Consolidation phase (5 days for every pound lost in phases 1 and 2): This phase includes unlimited lean protein and vegetables, some carbs and fats, one day of lean protein weekly, and 2.5 tablespoons of oat bran daily.
- Stabilization phase (indefinite): Follow the consolidation phase guidelines but with more flexibility, as long as your weight remains stable.
The early phases of the Dukan Diet may promote ketosis, where the body burns fat instead of carbs. However, later phases of the diet allow for higher quantities of carbs, making it unlikely for the body to maintain ketosis.
Maintenance phases are important for long-term weight loss success. They allow the body to take a break from dieting, which can be beneficial both physically and mentally. During the maintenance phase, it is important to find a balance and not indulge to the point of an energy surplus, as this will lead to weight gain. The maintenance phase should be continued until weight stabilizes, providing a good foundation for the next dieting phase.

The diet is restrictive and may be hard to follow
The Dukan Diet is a restrictive diet that may be hard to follow. It is a low-carb, high-protein diet that was first published in France in 2000. The diet has four phases, two for weight loss and two for weight maintenance. The first phase involves eating only protein, and the second phase alternates between protein and non-starchy vegetables. In the third phase, some carbs and fats are reintroduced, and the fourth phase involves following the consolidation phase guidelines while loosening the rules as long as weight remains stable.
The diet is restrictive because it eliminates many food groups, including fruits and vegetables, which can lead to a lack of important nutrients such as vitamin C and folate. It also discourages high-fat foods, which can be potentially good for health, and eliminates healthy sources of fiber, such as avocados and nuts. The diet is also high in protein, which can require more water intake, and the recommended water intake of 50.7 ounces (1.5 liters) may be too low for those on the diet.
The restrictive nature of the diet can make it hard to stick to. It can be challenging to shop for food and plan meals when only certain foods are allowed on certain days. Additionally, the lack of carbs in the early phases of the diet can lead to tiredness, as carbs are needed for energy. The diet may also cause other side effects such as nausea, vomiting, and diarrhea, as it puts the body into a state of ketosis, where the body burns fat for energy instead of carbohydrates. Ketosis can also lead to dehydration, as the kidneys remove more fluid.
The Dukan Diet is not suitable for everyone, and it is important to check with a doctor before starting the diet, especially for those with health conditions or digestive issues. The diet is not recommended for children, as it can lead to nutritional gaps that can affect their growth and development. It is also not intended for people with diabetes, eating disorders, renal heart failure, or depression.

The diet may cause nutritional deficiencies and health issues
The Dukan Diet is a high-protein, low-carb weight-loss program that has been criticised for promoting an unbalanced way of eating. The diet is split into four phases, with the first two focusing on weight loss and the last two on weight maintenance. The first phase involves eating unlimited lean protein and 1.5 tablespoons of oat bran per day. The second phase alternates between lean protein one day and lean protein and non-starchy vegetables the next, plus 2 tablespoons of oat bran. The third phase allows for unlimited lean protein and vegetables, some carbs and fats, and one day of lean protein weekly, with 2.5 tablespoons of oat bran daily. The fourth and final phase follows the same guidelines as the third but loosens the rules as long as the individual's weight remains stable.
In addition, the Dukan Diet may cause dehydration due to its low recommended water intake. It can also contribute to disordered eating and may not be a long-term solution for weight loss, as individuals may regain weight once they go back to unrestricted eating habits. Finally, a 2021 case study observed that two people who experienced rapid weight loss on the Dukan Diet developed a condition called pigment epithelial detachment in both eyes, which can lead to distorted vision.

The diet may lead to short-term weight loss but is unsustainable long-term
The Dukan Diet is a low-carb, high-protein diet that promotes weight loss through ketosis, a metabolic state where the body burns fat instead of carbohydrates for energy. While the diet may lead to short-term weight loss, it is not a sustainable long-term solution due to its restrictive nature and potential health risks.
The Dukan Diet is divided into four phases, with the first two phases being the most restrictive. During these initial phases, dieters are instructed to cut out most food groups and consume primarily lean protein, with some non-starchy vegetables and oat bran. This restriction of carbohydrates puts the body into a state of ketosis, leading to weight loss.
However, the highly restrictive nature of the Dukan Diet makes it difficult to follow long-term. The diet eliminates important sources of fibre, such as avocados and nuts, and restricts fruits and vegetables, resulting in a lack of essential nutrients like vitamins C and folate. This unbalanced approach can lead to nutritional abnormalities, including high levels of iron and potassium, as well as vitamins A and D.
In addition, the Dukan Diet can be complicated to follow due to its many rules and restrictions. It may also cause unpleasant side effects, such as nausea, vomiting, tiredness, and diarrhea, especially during the early stages as the body adjusts to ketosis. The diet's low recommended water intake can further lead to dehydration, and the high protein content may pose health risks for individuals with kidney, liver, or other health concerns.
While the Dukan Diet may lead to initial weight loss, it is not a sustainable or healthy long-term solution. Gradual lifestyle changes, such as focusing on minimally processed foods and increasing fibre intake, are more effective for long-term weight loss and maintenance.

Yes, the Dukan Diet puts your body into ketosis in the early phases. Ketosis is where your body burns fat for energy instead of carbohydrates. However, later phases of the Dukan Diet allow for higher quantities of carbs, so it is unlikely that ketosis will be maintained.
Putting your body into ketosis can cause side effects such as nausea, vomiting, tiredness, and diarrhea. These problems should go away in a few days or weeks as your body gets used to the diet. Ketosis can also cause dehydration because your kidneys remove more fluid.
The Dukan Diet has been criticised for being excessively restrictive, unsustainable, and promoting an unbalanced way of eating. It eliminates healthy sources of fibre, such as avocados and nuts, and discourages high-fat foods, which can be beneficial for health. The diet can also cause changes to hunger and satiety hormones, increasing hunger and food cravings. Additionally, it ignores key healthy eating principles, such as the importance of fruit and vegetables, the benefits of wholegrains and fibre, and the health benefits of selecting from a variety of food groups.
