Has anyone read about this?
Basically the concepts are that everything you put in your body requires work, a lot of which might be unnecessary. We all tend to over burden our systems on a meal basis. So the theory is once you have been living on a clean diet for quit some time the less you need to put into your system because at this point you assimilate whatever you have put in your body at a greater percentage (then say when you 1st became raw). So you don't need to stuff yourself day in and day out trying to get a huge amount of calories. Eat when you are hungry and stop when you are not.
The second concept includes dry fasting, and it's benefits.
I highly recommend reading the book called "Quantum Eating"
I find it very interesting and would like to get deeper on the topic, so I dedicated a forum website to do just that, and I hope that you join me.
I haven't read the book but I am familiar with the concepts. Personally, it makes no sense to me that one would need less calories the longer they are eating a healthy diet.
The amount of calories needed is dependent upon the individual's basal metabolic rate (BMR) and his or her activity level. The latter can obviously change at anytime, which will effect how much food is needed, but the former can change as well if their is a decrease or increase in weight.
