The suggestions in this article are constructive ones, however, they will, sadly, fail for a lot of people if one important factor is not addressed,..the possibility of one or more significant nutritional deficiencies.

Addressing deficiency means the body is not crying out for nutrition and seeking what it lacks however it can.   There is a condition called pica which is a specific form of this condition typically related to iron deficiency.   Also, a lot of women crave certain foods during pregnancy they would not otherwise want to eat.   

I'm not sure why medical science accepts nutritional deficiency as the basis for medical conditions in these specific cases (pica, pregnancy related cravings), and rejects it as a possible contributor to overeating and weight gain.   The only conclusion I can draw is there is not enough profit in it.
