the physics of atkins 漫话阿特金斯的物理原理漫话阿特金斯的物理原理 -by kidd dr. stephen d. phinney, m.d. and dr. jeff s. volek, ph.d. atkins diet the atkins diet involves limited consumption of carbohydrates to switch the bodys metabolism from metabolizing glucose as energy over to converting stored body fat to energy. this process, called ketosis, begins when insulin levels are low; in normal humans, insulin is lowest when blood glucose levels are low (mostly before eating). reduced insulin levels induceslipolysis which consumes fat to produce ketone bodies. on the other hand, caloric carbohydrates (for example, glucose orstarch, the latter made of chains of glucose) affect the body by increasing blood sugar after consumption. (in the treatment of diabetes, blood sugar levels are used carbohydrate counting.) fiber, because of its low digestibility, provides little or no food energy and does not significantly affect glucose and insulin levels. dr.atkins & his food the atkins richard david feinman richard david feinman (born 1940) is a professor of biochemistry and medical researcher at state university of new york health science center at brooklyn who studies nutrition and metabolism. his current area of research is the area of diet composition and energy balance. he is generally credited for doing the first serious scientific research on the atkins diet.he has published articles on application of thermodynamics to nutrition. new words & expressions scratch ones head: to think hard in order to find an answer to something invoke: to mention a person, a theory, an example, etc. o support your opinions or ideas, or as a reason for something eg: she invoked several eminent scholars to back up her arguement 1.detractor: one who disagrees or belittles the worth of something 2.conserve:(1) keep in safety and protect from harm, decay, loss, or destruction (2)keep constant through physical or chemical reactions or evolutionary change 3.dissipate:to cause to separate and go in different directions new words & expressions 4.molecular: relating to or produced by or consisting of molecules molecule: a molecule is defined as a sufficiently stable, electrically neutral group of at least two atoms in a definite arrangement held
