Diets with different macronutrient compositions involve a caloric intake of greater than 1200 kcal/day. This type of diet is designed to reduce the caloric intake by 500-1000 kcal/day from the patient's current dietary intake.

The suggested composition used by the best-validated dietary programs is as follows:

  • Protein intake of 0.8-1.5 g/kg of body weight (not to exceed 100 g/day)

  • 10-30% of total calories from fat (preferably ≥90% as polyunsaturated fat and < 10% as saturated fat)

  • Carbohydrate intake of 50 g/day or more

  • Water intake of 1 L or more

  • Adequate micronutrients and macronutrients based on the RDAs
