Dukan Diet

I did 3 days on the attack phase and lost about 4lb, and then have been eating protein & veg for the last 3 days and now weigh about 5.5lb less than this time last week. I like it because exactly as people have already said, it is helping me to break my sugar/carb habit, and I don't feel hungry outside of mealtimes anymore! Which is a huge change for me. I am getting a little bit tired of the eggs and meat though, alternating protein only with protein & veg days is going to be hard cos I'm not going to look forward to the protein only days! Maybe I need to do some more experimenting with different seasonings etc...

Out of interest, what are people eating for lunch on protein-only days? I take lunch to work, so it needs to be easily portable, and have been eating tins of tuna for lunch. Which is getting a bit boring! Any better ideas?

Not to be negative or anything, but just wanted to share some important info. This eating plan does not include all the nutrients you need for good health.
A multivitamin will not compensate for the nutritional goodness from fruits, whole grains and healthy fats that are inadequate in The Dukan Diet. When dieters start losing weight rapidly, they tend to continue the restrictive phases longer than advised -- which puts you at risk for nutrient deficiencies and kidney problems.
Losing more than 1-2 pounds per week can promote gallstones and muscle loss. "It is unhealthy to lose weight so quickly because you not only lose fat and fluids but precious muscle mass, which is really hard to replace, especially as you get older."

Some side effects, constipation, bad breath, dry mouth, and fatigue should be a red flag that this is not a healthy diet.
Your body’s preferred fuel to energize and keep you going is smart carbs, and when you eat a healthy diet you should feel great -- not have negative side effects.

There is no question this very restrictive diet will lead to weight loss, if you can actually follow it. But the elimination of healthy food groups, and the unpleasant side effects, makes the Dukan diet an unlikely choice for the long haul.

Protein is an essential part of a healthy diet, but it cannot stand alone. A truly healthy diet includes all the food groups -- vegetables, fruits, whole grains, and low-fat dairy and healthy fats along with lean protein. Your body needs the nutrients these foods provide.
Skip this fad diet. Instead, choose a calorie-controlled eating plan that you can stick with for the long term.
I have know doubt that you can lose weight, much like the Atkins Diet, but it's really not a healthy way to do it.

Thank you for your thoughts. I'm no expert on health and nutrition so I am not going to argue any of the points you are trying to get across.

All I can say is this. Since following this diet I have felt great, I have not experienced any side affects mentioned and I feel like I have loads more energy. Before following this plan I was eating tons of Carbs and Sugar, so I wasn't doing my health any favours!
