A diet is basically what a person eats, how much he eats and how often he eats. It is not just one or the other. It is all that and more.
A person's diet determines how much they get out of life. It might not be new to know that what a person takes in is what they use to work, think and ultimately find their place in the world. If a person eats things that are full of empty calories, based only on what is convenient to them they find that in their lives, they have to settle and compromise to get less than what they wanted.
Dieting tips can't be given by just anybody. Every one has a body type and their own routines so what one eats might be enough for them to have the energy to do the less than physically demanding work. So it follows that dieting tips are just guides. Checking if they fit one's lifestyle or the demands of it is important to make sure that one is not left with less energy or with excess fats.
