H.R......you are Sooooo right there.......as time goes by dieting leads to the loss of lean muscle leading to further fat deposits because fat burns nothing.......you need lean muscle to burn calories......the feast and famine thing is what causes all dieter to fail.

There are also some medical causes of a slow metabolism.....and these should be investigated......they are sometimes implicated in a fast metabolism too....Thyroid disease.
