Reduced energy diets (REDs) identify ways within a person’s current eating habits to reduce 2000 to 4000 kJ from their usual energy intake each day. Usual energy intake is the amount of energy you usually consume, although this can vary from day-to-day.
They usually involve swapping energy dense foods for low energy density foods and managing portion sizes. For example, including more fruits and vegetables and less take-away foods is a way to decrease the energy density of your dietary intake and following portion guides can reduce energy intake without having to change the types of foods you eat.
REDs have the highest adherence in the long term which means more sustainable weight loss however weight loss is slower than when following the other strategies.
