For anyone who needs it - I just typed this up, pulled from the book, for a friend who doesn't want to take the time to read the whole book. This information is all the intellectual property of Dr. Dukan!

DUKAN DIET
There are 4 phases: Attack, Cruise, Consolidation, and Stabilization. See below for details.

ATTACK PHASE:
During this period, which can vary between one and ten days depending on your circumstances, you have unlimited access to the food categories listed below. From these categories, you can eat all you want, without any restriction, at whatever time of day. Think of it as an all-day Eat As Much As You Want buffet.
The watchword is very simple and non-negotiable: you can have everything on the list without exception; everything that is not on the list is banned, so forget about those foods for the moment, knowing that very soon you will have them all again.
1. Lean meats: beef (except ribs and rib eye), veal grilled or roasted without oil or fat.
2. Offal: Kidneys, liver, beef tongue (tip)
3. All poultry, except duck and goose, but without the skin.
4. All fish, fatty, lean, white, oily, raw, or cooked.
5. All shellfish.
6. Low-fat ham, sliced low-fat chicken and pork.
7. Eggs
8. Non-fat dairy products.
9. At least one and a half liters of water with a low salt content.
10. Oat bran galette or 1-1/2 tbsp of oat bran added to milk or a dairy product.
11. A compulsory 20-minute walk per day.
12. Extras: Coffee, tea, vinegar, flavorings, spices, herbs, pickles, lemon (not lemonade) salt, and mustard in moderation.
Apart from these extras and the main food categories described, EAT NOTHING ELSE. All the rest, anything and everything that is not expressly mentioned on this list, is forbidden during the relatively brief period of time that the Attack phase lasts.
Therefore, concentrate on everything you are allowed to have and forget the rest. Vary your meals; mix and match in whatever order, make your menus interesting and never forget that you can have as much as you want off all the foods on this list.

CRUISE PHASE
Keep eating all the Attack diet foods and add the following vegetables, raw or cooked, without limiting quantities, combinations, or time of day: tomatoes, cucumbers, radishes, spinach, asparagus, leeks, French beans, cabbage, mushrooms, celery, fennel, all salad greens including chicory, Swiss chard, aubergines, courgettes, peppers. You can even include carrots, beetroot, and artichokes, provided you do not eat them at every meal. Throughout this Cruise phase, you will alternate periods of proteins with vegetables with periods without any vegetables until you reach your desired weight. (Note, must do alternating days in a combination that works for you. 1/1, 2/2, or even up to 5/5 days – 1 day pure protein, 1 day protein/veggies. Or 5 days pure protein, 5 days protein/veggies. Do this til you get to your goal weight.

CONSOLIDATION PHASE
How long this transition diet lasts is calculated according to how much weight you have lost, based on five days for every pound shed. If you have just lost 40 pounds, you have to follow it for 40 times 5 days, i.e. 200 days or six months and 20 days; 20 pounds is equivalent to 100 days. You can easily calculate the exact amount of time you need before reaching permanent stabilization.
The whole time you are consolidating your weight, you will follow this diet as closely as possible and you are allowed the following foods:
• The protein foods from Attack diet
• The vegetables from Cruise diet
• One serving of fruit a day, except bananas, raisins, and cherries
• Two slices of whole meal bread per day
• 1-1/2 oz of cheese per day
• Two servings of starchy foods per week
• Lamb and pork roast (lean cuts
Then to crown it all:
• Two celebration meals per week (you are free to choose, but no binging.)
But also, absolutely and without question:
• One day of pure protein (the Attack diet) per week, on the same day every week and without fail.


STABILIZATION PHASE
1. Go back to eating what you want 6 days out of 7, while keeping the consolidation foods as your safety base and platform.
2. Hold on to everything you have learned and the good habits you have acquired while completing the whole program.
3. Enshrine protein Thursdays as the day that protects you for the rest of your life.
4. Live your life as if lifts and escalators did not exist.
5. Also, take 3 tbsp of oat bran every day for the rest of your life.
If you neglect any of these five measures, you will put your weight management at risk. If you give them all up, sooner or later you will definitely put back on all the weight you have lost.
