Since the body is essentially a biological machine, it needs energy to maintain itself and function.  When not enough calories are consumed, the body will start burning stored fats and eventually muscles.  In the end, anorexia sets in and if this eating disorder is not treated, like Ana Carolina Reston you will simply die a slow and painful death.

The conclusion that one needs to eat a minimum number of calories in order to be able to function normally and not become ill (lack of calories lowers are defenses and infections are more likely to happen).  Thus, hunger is not an option.  The right way to do is to substitute higher calorie foods with lower calorie alternatives by eliminating fat and sugars.

Unfortunately, Hollywood celebs are going to the extremes to maintain their perfectly slim bodies.  In an excellent chart put together by Us magazine:

1. Elizabeth Hurley laments that she drinks water for breakfast and goes to bed hungry.
2. Amanda Seyfried follows a raw diet and will simply eat some spinach leaves with nuts for a meal.
3. Kristin Bauer confesses to be always being hungry.
4. Julianne Moore essentially does not have proper meals and occasionally eats an energy bar or yogurt.
