Advices

Avoid as much as possible fatty food, including fat from vegetables.

Reduce salt quantities.

Drink a lot, like 2 liters/day (slightly more than 1/2 gallon). Water is your best partner here, if possible drink diuretic waters like Evian or Vittel (sold at Wholefoods). Avoid sparkling water due to the sodium (salt).

As soon as he started practicing, Dr. Dukan realized that all the Cartesian theories and principles around nutrition and diets, were based on the fooled assumption that one could remove the temptation within overweight people for eating and convert them into calory-counting bureaucrats!!!

According to Dr. Dukan, most obese people are not obese by chance; there's a psychological side that has to be considered and understood and which goes down to the profound explanation of eating habits and self-commitment.

His conclusions were that overweight persons who are trying to loose weight need a fast return with, quickly, tangible results to build up their self-confidence and motivation. They also need precise objectives to be set with pre-defined and predictable phases in order to enable them to appreciate their efforts, comparing the results against the initial objectives.

"This method is dedicated to those who tried everything, who lost weight, often - too often - and who are looking, beyond everything else, for the certainty that in return of a committed and flawless effort, but limited in time, they will, first of all, lose weight and, even more, will enjoy the result of their effort and will live with the comfort and the body that they are reclaiming." Dr. Pierre Dukan.
