Answer

Conventional diets can be broadly classified into 2 categories: balanced, low-calorie diets (or reduced portion sizes) and diets with different macronutrient compositions. The latter include the following:

  • Low-fat diets - Eg, the Ornish diet

  • Low-carbohydrate diets - Eg, the Atkins diet

  • Midlevel diets - Eg, the Zone diet, in which the 3 major macronutrients (fat, carbohydrate, protein) are eaten in similar proportions of 30-40%)

  • Joslin Why WAIT diet for diabetic patients - 40-45% carbohydrates, 20-30% protein, less than 35% fat
