What You'll Learn

The Attack phase duration depends on weight loss goals
The Dukan Diet is a high-protein, low-carb weight-loss diet that is split into four phases. The first phase, also known as the Attack Phase, involves eating predominantly protein-rich foods that are reasonably low in fat. The duration of the Attack Phase depends on the individual's weight loss goals.
The Attack Phase can last from one to ten days, depending on the weight loss goal. For those looking to lose less than 10 pounds, the Attack Phase should be followed for one day. If the weight loss goal is less than 20 pounds, the phase should be followed for three days. For those aiming to lose 20 to 40 pounds, the recommendation is to stay in the Attack Phase for five days. Individuals with a weight loss goal of more than 40 pounds may stay in this phase for seven to ten days, but it is advised to seek medical advice first.
During the Attack Phase, individuals can eat as much as they want of the approved high-protein foods and are encouraged to drink plenty of water. Approved foods include lean beef, fish, chicken, eggs, soy, cottage cheese, and fat-free dairy. It is important to note that no other sources of higher-fat protein are permitted during this phase.
The Attack Phase aims to kick-start the metabolism and induce rapid weight loss. By restricting carbohydrates and fats, the body enters a starvation-like state, forcing it to use fat stores for energy. This can lead to water loss and dehydration, resulting in rapid weight loss. However, it is important to note that the Dukan Diet has been criticised for being complicated, restrictive, and potentially lacking in important nutrients.
After the Attack Phase, individuals move on to the Cruise Phase, where they gradually introduce non-starchy vegetables while continuing to consume lean proteins. The duration of the Cruise Phase is based on a schedule of three days for each pound of desired weight loss. The subsequent phases focus on maintaining weight loss and adopting a generally healthy diet, including one all-protein day per week.

It involves eating high-protein, low-calorie foods
The Dukan Diet is a four-phase diet plan created by French doctor and nutritionist Pierre Dukan in 2000. It is based on the theory of eating a lot of protein to lose weight. The first phase, the Attack Phase, involves eating high-protein, low-calorie foods and can last from one to seven days, depending on the weight loss goal.
During the Attack Phase, dieters are allowed to eat unlimited amounts of lean animal proteins, including poultry, beef, pork, fish, and shellfish. In addition, two tablespoons of oat bran per day are recommended for added fibre. The diet also emphasizes the importance of drinking 6 to 8 cups of water daily.
The Attack Phase aims for rapid weight loss by kick-starting the metabolism and inducing a state of ketosis, where the body burns fat for energy instead of carbohydrates. However, it is important to note that dietitians disagree that any particular foods can kick-start the metabolism, and that initial weight loss is mainly due to water loss and dehydration.
The Dukan Diet is very restrictive, and during the Attack Phase, all other foods besides the approved protein sources are off-limits. This includes cutting out most food groups and restricting carbohydrates and fats. While this diet may promote weight loss, it can be challenging to maintain due to its restrictiveness and the need to prepare meals from scratch.
It is also important to consider the potential health implications of the Dukan Diet. Health experts have warned that it may not be nutritionally balanced and could increase the risk of long-term health problems. Additionally, a high-protein diet may be harmful in the long run as it lacks important nutrients such as calcium, iron, potassium, and vitamins A, C, and D. Therefore, it is always recommended to consult with a healthcare professional before starting any new diet.

It includes 20 minutes of daily exercise
The Dukan Diet is a high-protein, low-carb diet that was created in 2000 by French doctor and nutritionist Pierre Dukan. It consists of four phases, with the first phase being the Attack Phase. This phase is focused on rapid weight loss and involves eating foods from the "'pure protein' list, including chicken, shellfish, eggs, and goji berries. It can last from one to seven days, depending on how much weight an individual needs to lose.
During the Attack Phase, it is recommended to include 20 minutes of daily exercise. This can be in the form of brisk walking, which is an accessible activity for most people. It is important to note that exercise can boost metabolism, and when combined with a high-protein diet, it may contribute to weight loss. However, it is always advisable to consult a doctor or nutritionist before making significant dietary changes.
The suggested 20 minutes of daily exercise during the Attack Phase aligns with the overall Dukan Diet's emphasis on daily physical activity. This phase-specific exercise routine serves as a starting point for individuals embarking on the diet. As individuals progress through the subsequent phases, the recommended exercise duration and intensity may increase gradually.
In addition to the Attack Phase's exercise recommendation, it is crucial to stay hydrated by drinking at least 1.5 litres of water daily. This hydration guideline is consistent across the Dukan Diet, ensuring individuals stay adequately hydrated during their weight loss journey.
The Dukan Diet, with its Attack Phase and daily exercise routine, promotes a holistic approach to weight loss. By combining a high-protein diet with daily exercise and adequate hydration, individuals can work towards their weight loss goals. However, it is important to consult with healthcare professionals to ensure a safe and sustainable approach to weight management.

It's the first phase of the Dukan Diet
During the Attack Phase, people can eat as much as they want from a list of 68 to 72 pure proteins, including lean beef, fish, chicken, eggs, soy, cottage cheese, and fat-free dairy. These foods should be low in fat and contain no added sugars. In addition to these protein-rich foods, people are also advised to consume 1.5 tablespoons of oat bran per day and drink 1.5 litres of water.
The Attack Phase is designed to promote rapid weight loss by putting the body into a state of ketosis, where it burns fat for energy instead of carbohydrates. This phase is very restrictive, and people following it must be careful not to deviate from the approved foods. Dr Dukan has stated that even a tiny lapse will result in losing all the benefits of this phase and requiring a restart.
The Dukan Diet was created by French doctor and nutritionist Pierre Dukan in the 1970s and published in 2000. It has been criticised by health experts for not being nutritionally balanced and potentially increasing the risk of long-term health problems. It has also been called "complicated" due to its many rules and restrictions, which can make it challenging to maintain.

It's followed by the Cruise phase
The Dukan Diet is a high-protein, low-carb weight-loss diet that is split into four phases. It was created by Dr. Pierre Dukan, a French general practitioner who specializes in weight management. The first phase, the Attack Phase, involves eating foods from the "pure protein" list, including lean beef, fish, chicken, eggs, and fat-free dairy. This phase usually lasts for around 2–5 days, but it can be longer for those looking to lose more weight. It is followed by the Cruise Phase.
The Cruise Phase of the Dukan Diet is the second phase of the diet plan. This phase aims to lower a person's body weight gradually by adding 32 specific vegetables to the diet. The length of the Cruise Phase is based on a schedule of three days for each pound of weight loss desired. For example, if a person wants to lose 5 pounds, they would remain in the Cruise Phase for 15 days. During this phase, people are encouraged to increase their oat bran intake to 2 tablespoons per day.
In the Cruise Phase, dieters alternate between one day of only lean protein and one day of lean protein mixed with non-starchy vegetables. It is important to note that fruit is not permitted during this phase. In addition to dietary changes, the Dukan Diet also recommends daily exercise. During the Cruise Phase, it is suggested that individuals complete 30 minutes of brisk walking each day.
The Dukan Diet is a very restrictive diet that eliminates many healthy foods and may not be nutritionally complete. It can be challenging to stick to and may not be suitable for long-term weight loss. Health experts have warned that this type of diet could increase the risk of long-term health problems if people do not strictly follow the rules. It is always recommended to consult with a healthcare professional before starting any new diet plan.
