Remembering what my father used to say to me; which I have actually found to be true over years, is that Free from all waste and poison, and when no solid food has been taken for some time, one's body functions without obstruction and one feels a surge of vitality through out one's system.
Nowadays some people are beginning to believe that calorie restriction may even elongate/extend life, though this has not be proven.
So it is safe to say that calorie reduction certainly helps one to lose weight and perhaps then feel better within oneself, if it is not overdone for vanity's sake.
People must appreciate we are not all built the same and we cannot all be thin, heck some people who are built succulently naturally, look awful when they lose weight and start to appear gaunt and hollow cheeked.
The right balance has to be struck so we don't send our youngsters the wrong message.
They have to now it is okay to have some flesh on their bones, or to be slightly chubbier than some of their friends, and they are just as beautiful; if not even more beautiful as a result of their feminine curves.
