Does It Work?
While the Dukan Diet may not be as popular as theketo dietor thepaleo diet, this meal pattern is gaining traction in the weight-loss world, thanks to lofty promises to help people lose weight quickly. And although the Dukan Diet might be linked to some appealing potential outcomes, it does have some aspects that raise red flags regarding how healthy it actually is. To learn more about what the Dukan Diet is and whether you should try it out, read on.
The #1 Habit You Should Break to Lose Weight, According to a Dietitian
What Is the Dukan Diet? And How Does It Work?
Phase 1: The Attack Phase
The attack phase is intended to jump-startweight loss. During this first phase, participants will eat only lean protein from the allowable protein list the diet provides, along with 1.5 tablespoons of oat bran and a minimum of 6 cups of water per day. Similar to other low-carb plans, your body is supposed toenter ketosis, with the idea that you will use your fat stores as fuel. It is also recommended to include moderate exercise each day. Typically, the attack phase lasts three to seven days, depending on how much weight a person wants to lose.
Protein foods allowed in this phase include lean meats, fish, eggs, nonfat dairy products and seitan. Small amounts of oil, lemon juice and pickles are permitted.Artificial sweeteners, dietary gelatin andshirataki noodles—low-carb noodles made from glucomannan—can be eaten in unlimited quantities.
Phase 2: The Cruise Phase
Most of the weight loss will come during the second phase of the Dukan Diet, related to the implemented restrictions and guidelines. Transitioning into phase 2 means adding nonstarchy vegetables to the diet in unlimited amounts every other day. Examples of nonstarchy vegetables include zucchini, green beans, eggplant, onions, mushrooms, lettuce, celery and cucumber. Additionally, the plan recommends increasing the oat bran quantity to 2 tablespoons per day. One teaspoon ofolive oilto cook vegetables is allowable.
The average length of this phase is based on a schedule of three days for every pound you want to lose and can last several months, depending on your goals. The amount of weight loss that should be achieved should coincide with the “true weight” determined at the beginning of the diet.
Phase 3: Consolidation
This phase is considered a maintenance phase to prevent regaining the lost weight and solidifying the new eating and exercise habits in the diet. Participants start to add back previously restricted foods such as fruit, cheese,whole-grain productslike bread and pasta and celebration “treat” foods and meals in specific quantities. This phase requires that you make one day a week a “pure protein day,” essentially meaning that you follow the guidelines for the attack phase once a week. Oat bran and exercise are included in this phase as well.
Phase 4: Stabilization
Stabilization is essentially how a person should eat indefinitely, according to the diet. During this final phase, a person will follow three rules—reserve one day a week for eating pure protein and following the “attack phase” guidelines, eat 3 tablespoons of oat bran per day andwalk 20 minutes each day.
The consolidation phase should be used as the basis for planning meals during the stabilization phase, helping people avoid eating whatever they please without considering the nutritional content and value. No foods are off-limits, but quantities of foods like fruit are limited.
Certain versions of this diet require people to use the stairs instead of taking the elevator. People can also reintroduce moderate amounts of alcohol during this final lifetime phase.

Does the Dukan Diet Work?
You are likely to lose weight whenever you make drastic changes to your diet, especially when reducing the quantity of food eaten. While this diet may result in people experiencing short-term weight loss, sustained weight loss may not be seen, as is the case with many low-carbohydrate and restrictive diets.
And, as with any diet that eliminates or limits many foods, people can risk experiencing nutritional gaps, possibly resulting in vitamin and mineral deficiencies, digestive challenges, fatigue and other undesirable side effects. Plus, any highly restrictive diet might not be sustainable or enjoyable to follow. With many restrictive diets, people regain the weight once they stop following the diet.
A study evaluating the effectiveness of the Dukan Diet against a general low-calorie diet showed that the individuals on the Dukan Diet lost more weight and reduced weight circumference more than those following a low-calorie diet.The participants also had improvements in triglyceride levels and insulin resistance. The study was small, with 34 participants; the diets of the participants in the traditional low-calorie diet were not controlled, unlike the structured phases of the Dukan Diet. Also of note, with the participants following the Dukan Diet, weight loss was steady for 6 months, but then participants began regaining weight until the 12-month study completion.
If a person chooses to follow the Dukan Diet, they should only do so under the guidance of their healthcare provider or a dietitian. This is especially important during the first two phases of the diet when a person may experience constipation, fatigue and even bad breath, due to thelack of fiber and carbstheir body is receiving.
What Happens to Your Body When You Lose Weight Fast
The Bottom Line
The Dukan Diet has been followed for decades due to the rapid weight loss people often experience in the short term. And while it is true that weight loss will likely be experienced when eliminating entire food groups, people may increase their risk of experiencing other unsavory side effects when they adopt this eating pattern.
For a person who needs to experience rapid weight loss, this diet is an option that could be explored under the advice of a healthcare provider or dietitian, especially if the person does not have any underlying health concerns like heart disease or diabetes. But for a person who wants to eat in a way that supports their overall health, more balanced and sustainable diets like theMediterranean Dietmay be a better match for long-term health benefits and lasting weight loss.
