I have tried many diets. Most were unsuccessful and I felt hungry and tired. I lost 8,5 KG on the Dukan diet 5 years ago. I've slowly gained some of the weight back. I tried Keto but that was totally unsustainable. I revisited the Dukan book and I am slowly training myself to take control. I love that you are allowed to eat as much as you want but the food is restricted. That's fine for me as I am not a fancy cook. It really does work if you are 100% and it's fast.

the diet really works i am a living testimony but it takes a lot of discipline and obedience i can recommend it to anybody please give it a try. Athough i failed the first time i am determined to go through it all because it is the only diet that works

It's not the fats that make you gain weight so much as the sugar and processed food we eat if they remove all or most of the good fat they need to add something to bring back the flavour which is often sugar and that's the demon,even too much fruit can be a problem that's why juicing fruit does not make sense to me,eat the whole fruit at say 4 tsp of sugar instead of four juiced apples with about 16 tsp's

Although I lost close to 10kgs on this diet, I subsequently developed colonic polyps and was then diagnosed with cancer (retroperitoneal leiomyosarcoma). Too much protein not enough vegetables and fruit.

I gained 20 kg with my second pregnancy.After strenuous exercise, low calorie diet ,I managed to bring my weight from 85 to 77 Kg.Then it was stuck.One of my colleagues recommended me Duken diet.In first 7 days .scale moved from 77 to. 75 kg.
From then onwards I did. 5 days protein diet ,5 days mixed phase diet.I had few weeks of free food but I tried not to eat Carbs at all .
Today after 8 months of having baby my weight is 61 Kg.Its amazing .Highly recommended diet for Aussies
U can have coffee. , and u don't need to starve.

I am on Day 4 of the Dukan Diet. I have tried so many others, CSIRO, Naturopath written diet (avg 800 calories a day), Liver Cleansing, etc. This is the 1st diet that I have seen results without being hungry. I have had reasonable energy, one headache (not necessariy the diet). I thought I would really struggle with protein only, but there is variety, you just have to be creative! I have lost 900g in the 4 days but on the other diets I really struggled to lose anything. I am hoping to continue the Attack phase for the 7 days as recommended by the Dukan diet calculator. Time will tell!
inexpensive compared to Weight Watchers, etc and easy to stick to.
Can get boring if you dont get creative with allowed ingredients.

I haven't bought the book, but I did follow the diet from information I found online. It has worked very well, I've been losing about 1kg per week (I am on phase 2).
I tried several other diets, and none worked like this.
lately my weight has leveled off, so I cut my food intake by half.
Now the weight loss is back to a normal rhythm, and I am not hungry at all !
just works
very hard to have a social life

I am on day 8 phase 1, lethargic feelings are gone and hunger pains no more hav lost nearly 5kgs and 28cm all up, I am looking forward to phase 2, PV days I hav a long way to go but very confident, usually by this time on any other diet I start falling off the diet cause nothing is happening so all I can say is if its for you preserve, I know my weight loss will get slower but what a start I happy!
Its working
A bit lethargic but passes

I've been following the Dukan diet since 28/1/12 and have lost a total of 17 kg's.
It's been the easiest and most effective diet I've ever been on and I've been on a few.
I am half way through the 3rd phase (consolidation) and it's so easy that I don't even think of myself as being on a diet anymore, it's a way of life.
I'm very confident that I won't put the weight back on because I now know what foods to eat and what not to eat and what works for me.
My husband has also lost 10 kgs and we've never been fitter or healthier and we're both nearing 60
It may not work for everyone but it certainly is working for me
Very effective and easy to follow
Expensive and time consuming

I am nearly finished phase three of the Dukan diet. I've lost 17 kilos and have stabilised well. I have rarely felt hungry and don't miss sugary and refined foods (simple carbohydrates) at all. The only down side I experienced was for phase one and some of phase two, extreme lethargy when exercising. I put that down to the absence of the aforesaid foods and it passed after a couple of months.
Easy to follow and plenty of options.
None that I can see. Perhaps some will see having to constrain socialising for a while a con but I didn't.

Have lost 9kg in 3 months-have taken it easier at weekends when I want some wine and carbs:then I get staright back into it on the weekdays,it still works for me,weight still goes down though a little slower.I also do a lot of exercise and find that if you couple that with the diet it works better.Drinking lots of water is also paramount:-the days I don't drink the required amount are the days my weight doesn't shift no matter how careful I am with the diet.
No weighing food or portion control
Protein only for more than 4-5 days at a time is tough

I have been following the “attack phase” of this diet to the letter, no sugar, very very little salt, NO dairy at all (I don't like it anyway) drinking at least 2 - 3lt lt of water per day only two cups of black coffee, no sugar or milk and as a result going to the toilet very very often. (About 4-6 times in the morning alone) Been eating as per the plan in the book and I have put on weight.
You can register on their forum but you MUST pay 170 pound to even ask questions as you MUST subscribe.

For the people who it has worked for them, that's great, but for me, it was the exact reverse. I put on weight.
Easy to follow, not hungry at all
Expensive, and did not work for me
