By definition, each person’s True Weight is personal. For starters, it must take a person’s age and gender into account. For example, we know that with each decade, a woman’s stable weight needs to be increased by 1.8 pounds and a man’s by 2.6 pounds. Furthermore, a person’s needs, and especially the likelihood of achieving a certain weight, will differ between age 20 and age 50. When working out this True Weight, family history must also be considered. Here again, there is no point asking a woman whose family has a history of obesity to aim for the same stable weight as a woman whose family is by nature slim. In addition, it is absolutely essential to include the history of a person’s weight problems, the crucial moment when weight started to get out of control: was it childhood, adolescence, or at a time of major stress, medical treatment, or depression— or for a woman, at her first contraceptive pill, with pregnancy, or in perimenopause? Each person is different from the next, and these differences need to be taken into consideration. It is also equally necessary to take into account what I call the “weight range”—the difference between the least someone has ever weighed after the age of twenty and the most the person has weighed apart from during pregnancy. This range tells us what is recorded in that person’s biological memory and remains there forever. Also, figuring into calculating a person’s True Weight is how many unsuccessful diets have been followed, and which ones, as there are some diets from which the body never quite recovers— diets that go against nature and trigger “body anxieties.” The best known of these diets are based on powdered or liquid meal substitutes, which are the very opposite of what is natural for humans to eat.
You can see that there are many different parameters used to calculate a person’s True Weight and that it is too complex to be calculated just by using pen and paper. I recommend that you go to the Dukan Diet website (www.dukandiet.com), where you will find a free questionnaire with eleven questions that will let you find your True Weight. Answer them, and you will have your True Weight straightaway.
