The metabolic effects of low-carbohydrate diets and incorporation into a biochemistry course

Abstract

One of the challenges in teaching biochemistry is facilitating students' interest in and mastery of metabolism. The many pathways and modes of regulation can be overwhelming for students to learn and difficult for professors to teach in an engaging manner. We have found it useful to take advantage of prevailing interest in popular yet controversial weight-loss methods, particularly low-carbohydrate diets. The metabolic rationale behind these eating plans can be linked to glycolysis, the citric acid cycle, lipolysis, gluconeogenesis, ketosis, glycogen metabolism, fatty acid oxidation, and hormonal regulation. When this approach was used in undergraduate biochemistry classes at the State University of New York at Geneseo, students were highly motivated to learn the biochemical principles behind these diets. The following provides information about low-carbohydrate diet plans that will enable professors to speak authoritatively on the subject. History and studies regarding efficacy as well as biochemical metabolic effects are included. © 2005 by The International Union of Biochemistry and Molecular Biology.
