With all my 3 babies I lost weight very easily post birth... so for me it was fiction. I put it down to breast feeding and my body using up my excess fat deposits that way. I am also a moderate eater... not alot of junk... and I don't drive... walking everywhere/ catching public transport really helps me keep my weight down I think... and I have never dieted. I eat full-fat everything...and I add cream to my daily coffee. I am happy with my weight.
