Leptin
The discovery of leptin little more than a decade ago, as a hormone produced in white adipose tissue with an important role in satiety and energy expenditure, was a seminal event in our understanding of adiposity. This initial advance in the new endocrinology of obesity was soon followed by the realization that leptin was not only produced in adipose tissue, but in many different tissues of the body, and that receptors were similarly distributed. Additionally, the early recognition of infertility that was associated with leptin deficiency prompted research that identified roles for the polypeptide in virtually every area of reproductive biology.
A Primer for the Exercise and Nutrition Sciences : Thermodynamics, Bioenergetics, Metabolism
Provides a fresh approach to the study of energy expenditure by introducing the latest concepts in open system thermodynamics and cellular to whole-body energy exchange. A journey is undertaken by the reader, beginning with what energy is and where the energy in glucose is found, and ending with the concept of high versus low intensity exercise in augmenting weight loss.
