Studies in humans, cats and dogs have all substantiated positive weight loss results when adding fiber to calorie restricted programs. Canned green beans provide extra fiber, are generally a hit with dogs, and only contain about 50 calories per can. Human subjects report a greater sense of satiation or âfullnessâ with the fiber addition and tend to eat less if given free access to food.
1 Excitation occurs when the radiation excites the motion of the atoms or molecules, or excites an electron from an occupied orbital into an empty, higher-energy orbital.  Ionization occurs when the radiation carries enough energy to remove an electron from an atom or molecule.
Electromagnetic radiation is made when an atom absorbs energy. The absorbed energy causes one or more electrons to change their locale within the atom. When the electron returns to its original position, an electromagnetic wave is produced. Depending on the kind of atom and the amount of energy, this electromagnetic radiation can take the form of heat, light, ultraviolet, or other electromagnetic waves. There are several ways of causing atoms to absorb energy. One way is to excite the atoms with electrical energy.
