The Dukan Diet is a high-protein, low-carb weight-loss plan that was first published in France in 2000 by Dr. Pierre Dukan. The diet is divided into four phases, two for weight loss and two for maintenance. The first phase, the 'attack' phase, involves eating only lean protein and a small amount of oat bran, and drinking a minimum of six cups of water per day. In the second phase, non-starchy vegetables are introduced. The third phase, the 'consolidation' phase, involves following the guidelines of the second phase but loosening the rules as long as weight remains stable. The final 'stabilization' phase involves maintaining improvements achieved in the earlier phases. The Dukan Diet is very restrictive, and there is limited scientific support for its efficacy.

| Phase 4 | Stabilization phase: no foods are off-limits, but continue having 3 tablespoons of oat bran a day and follow the protein rules from the attack phase once a week |
| Weight Loss | Weight loss is likely in the initial phases, but it may be hard to maintain |

What You'll Learn
The four phases
The Dukan Diet, created by Dr. Pierre Dukan, is a high-protein, low-carb plan that promises rapid weight loss. The diet is divided into four phases: Attack, Cruise, Consolidation, and Stabilization. Each phase has its own dietary pattern and restrictions, with the first two phases focusing on weight loss and the last two on weight maintenance.
During the Attack phase, dieters consume only lean protein from a list of approved protein sources, along with 1.5 tablespoons of oat bran and at least six cups of water per day. This phase is designed to jump-start weight loss and is very restrictive, with most food groups being cut out. The duration of this phase depends on the individual's age, weight loss history, and other factors, but it typically lasts between two to five days.
In the Cruise phase, non-starchy vegetables are reintroduced, and dieters can enjoy one to two celebration meals per week. The Consolidation phase further loosens the restrictions, allowing for a wider variety of foods. However, dieters must continue to have one pure protein meal day per week and stick to the Consolidation phase guidelines.
The final phase, Stabilization, is all about maintaining the weight loss achieved in the previous phases. No foods are strictly off-limits, but dieters should continue to have one pure protein meal day per week, increase their oat bran intake to three tablespoons per day, and take the stairs whenever possible. This phase is indefinite, and individuals can eat whatever they like except for one day a week when they follow the all-protein rules from the Attack phase.

Weight loss and health risks
The Dukan Diet is a high-protein, low-carb weight loss plan split into four phases. The first two phases are very low in carbohydrates, and the final two phases are maintenance phases. The diet is quite restrictive, and many people will find it challenging to stick to.
The diet is likely to be nutritionally imbalanced, and may not provide enough calcium, iron, potassium, and vitamins A, C, and D. The Dukan Diet also eliminates healthy sources of fiber, such as avocados and nuts, because they are considered too high in fat. The diet's high protein content may pose health risks for people with kidney disease, and it does not contain enough fiber for people with heart disease. The diet may also be unsuitable for people with diabetes, gout, liver disease, or digestive issues.
The Dukan Diet's recommended water intake of 50.7 ounces (1.5 liters) is likely too low given the increase in protein, which requires more water intake. This low recommended water intake could lead to dehydration. The diet may also cause constipation, bad breath, tiredness, and headaches.
While the Dukan Diet may lead to weight loss in the initial very strict phases, many followers regain the weight they lost. The diet's restrictive nature and extreme calorie restriction may make it hard to follow and contribute to disordered eating in the long run.

Pros and cons
Pros
The Dukan Diet is a low-carbohydrate, high-protein weight loss program. It is based on the premise that you don't lose weight when you are hungry, and the majority of calories and nutrients come from protein, which is more filling than carbohydrates. The diet recommends healthy sources of protein, encourages physical activity, and limits alcohol and sugar consumption. It also includes oat bran to get fiber. The diet is divided into two weight loss phases and two maintenance phases, with specific lists of foods that are allowed in different phases. The diet is also gluten-free in the earlier phases.
Cons
The Dukan Diet is very restrictive, especially in the first two phases, and can be hard to stick to. It may also be too expensive for some. The diet eliminates healthy sources of fiber, such as avocados and nuts, and can lead to inadequate amounts of vitamins and minerals. It can also be complicated due to the many rules and food restrictions, making it difficult to shop for food and plan meals. The diet may also cause side effects such as constipation, bad breath, tiredness, and headaches, especially in the early stages when the body is in ketosis. The huge amount of protein in this diet can pose health risks, and it may worsen cardiovascular health.

Dukan diet and exercise
The Dukan Diet is a nutrition program developed by Dr. Pierre Dukan, a French doctor and nutritionist. It is a low-carbohydrate, low-fat meal plan centred on lean protein, drinking water, and taking a 20-minute daily walk. The diet is divided into four phases: attack, cruise, consolidation, and stabilization. Each phase has specific dietary patterns and guidelines, with the first two phases being very restrictive.
The attack phase primarily comprises high-protein foods, non-fat dairy, and a few low-calorie options. During this phase, you should exercise for 20 minutes every day, which can include walking, running, or other workouts. The second phase, or cruise phase, involves adding non-starchy vegetables to the diet in unlimited amounts every other day, along with increasing oat bran intake. This phase sees a significant increase in exercise time, recommending 30-60 minutes of daily physical activity.
In the consolidation phase, you follow the guidelines of the previous phase but with some relaxed rules, provided your weight remains stable. Oat bran intake is further increased to 3 tablespoons per day. The exercise time decreases in this phase, as the focus shifts to maintaining the weight lost in the earlier phases.
The final stabilization phase is about maintaining long-term weight loss. There are no strict food restrictions, but you should continue having one pure protein meal a day and taking the stairs whenever possible. Exercise remains an essential component, with a recommendation to walk or run for at least 20 minutes daily to maintain and balance your weight.
While the Dukan Diet may promote rapid weight loss, it is essential to consult a healthcare professional before starting this or any other restrictive diet to ensure it aligns with your health needs. The diet's restrictive nature can lead to nutritional deficiencies and is not suitable for individuals with certain chronic conditions. Additionally, the lack of carbohydrates may cause side effects such as nausea, tiredness, and headaches.
