Although it is technically more accurate to prefer body mass to body weight, the term weight is overwhelmingly used in daily English speech and in biological and medical science contexts. Body weight is measured in kilograms throughout the world. Most hospitals in the United States use kilograms for calculations, but use kilograms and pounds simultaneously for other purposes (a pound is 0.46 kg). Many people in the U.K. still measure their weight using the stone equal to 14 lb (6.35 kg)...
Obesity is a condition in which the natural energy reserve of humans or other mammals, which is stored in fat tissue, is expanded far beyond usual levels to the point where it impairs health. |
