They say concentration of ketones positively correlates with more weight loss... well is this cause or effect? Is the increase concentration of ketones a CAUSE of weight loss or is it the RESULT of losing weight? I'm more likely to believe the latter.

Although ketosis is the basic subject on which low carb diets are based, Each one of us seems to have his own explanation of this subject.
Even Dr. Atkins himself despite my great respect for him has mentioned a phrase in his book about ketosis which I can't agree with. His phrase was:
"There is no lipolysis without ketosis, no ketosis without lipolysis."
If there was no lipolysis without ketosis we could have seen that the people who are on high carb low calorie diet who lose plenty of weight produce a large amounts of ketones, but this is not true.
And if there was no ketosis without liplysis we would not have seen low carb dieters who are not losing or even gaining weight while noticing high concentration of ketones in their urine. The source of theiir ketones must be dietary fat.
Here is my explanation for the subject of ketosis:
There are two methods to metabolize fats:
(1) The default method in which fatty acids go through series of processes and end with a fuel which is used for energy. After all the body's energy needs are met, the left over energy is stored as body fat.
(2) The second method in which fatty acids break into ketone bodies and a different kind of fatty acids (shorter in chain length) before they complete their journey. Ketones supply body cells with energy. After all energy needs are met, ketones can only exit the body. They cannot be stored as body fat.
To my believe, the body uses the first method alone when carb intake exceeds (100-120) carbs depending on the individual.
When carb intake is reduced below this amount, the two methods take place at the same time and method 2 share grows as the carb intake moves down twards zero.
So carb reduction acts like moving a mode switch slowly from one extreme to another. The first extreme is for a fully vegetarian human (during the pre-agriculture era) and the second extreme is for a fully meat eating human.
The vegetarian human can metabolize fats, but probably not the perfect way. The meat eating human metabolizes fats better and safer.
Ketones do not appear in the urine or saliva until they exceed the amount the body can use. This is why you don't notice them unless you eat 35 carbs or less.
