“In each day you should consume one type of food such as meat, fish, vegetables, dairy products, eggs, or fruits.” which indeed doesn’t sound really healthy on the long term…

Here http://www.liveandfeel.com/diets/dissociated_diet.html it says:
“This is not a fast weight-loss diet. You lose weight slowly but constantly. Actually, it is a way of life and the new achieved weight can be maintained without problems.”

Here http://www.frenchsensations.com/20080616/disassociated-diet/ it says:
“This diet works well if you’re willing to completely change the way you eat.”

Here http://en.wikipedia.org/wiki/Dissociated_diet it also sounds like it’s more a new way of eating than a short change of your diet.

Yours just saying the complete opposite: quickly lose weight and do it on a really small period of time.
