Btw, you don't realize that eating whole food and fasting are "effective" for the same reasons. Both are absent of the stimulus which caused the imbalance in the first place. That stimulus being imbalanced food.

Remove the stimulus, and the body winds down the compensation you call "excess fat". There many other reasons to fast, but doing it to lose weight is silly unless the foods themselves are changed. The actual problem is going unaddressed and fasting just relieves the symptoms until you do it all over again.
