What does a clinician need to know about low-carbohydrate (LC) diets? This review examines and compares the safety and the effectiveness of a LC approach as an alternative to a low-fat (LF), high-carbohydrate diet, the current standard for weight loss and/or chronic disease prevention. In short-term and long-term comparison studies, ad libitum and isocaloric therapeutic diets with varying degrees of carbohydrate restriction perform as well as or better than comparable LF diets with regard to weight loss, lipid levels, glucose and insulin response, blood pressure, and other important cardiovascular risk markers in both normal subjects and those with metabolic and other health-related disorders. The metabolic, hormonal, and appetite signaling effects of carbohydrate reduction suggest an underlying scientific basis for considering it as an alternative approach to LF, high-carbohydrate recommendations in addressing overweight/obesity and chronic disease in America. It is time to embrace LC diets as a viable option to aid in reversing diabetes mellitus, risk factors for heart disease, and the epidemic of obesity.

nutritional deficiencies: dietary advice and its discontents | jessica hayes-conroy, hobart & william smith colleges | adele hite, north carolina state university | kendra klein, san francisco physicians for social responsibility | charlotte biltekoff, university of california, davis | aya h. kimura, university of hawaii Doing Nutrition DifferentlyAbstract: This conversation is part of a special issue on ''Critical Nutrition'' in which multiple authors weigh in on various themes related to the origins, character, and consequences of contemporary American nutrition discourses and practices, as well as how nutrition might be known and done differently. In this section, authors reflect on the limits of standard nutrition in understanding the relationship between food and human health. They also focus on how nutrition practitioners are or could be creating different practices for how nutritional information is made available, shared, and absorbed. Among the different frameworks under discussion are individualized nutrition, ecological nutrition, critical dietary literacy, feminist nutrition, and technologies of humility.
