Brief Summary:
Investigators presumed that low energy density (LED) diet consumers will have lower risk of cardiovascular disease and are able to maintain their weight longer .

Condition or disease Intervention/treatment Phase
Body Weight Decreased Other: low energy dense Other: control Other: diet Phase 3

Detailed Description:
Previous studies introduced different dietary interventions for weight loss maintenance. Besides the debate on low fat or low carbohydrate diets, focusing on some food groups including fruits, vegetables and low fat dairies in the diet may be helpful for weight maintenance. However, energy intake is the key factor of weight maintenance. Energy intake will decrease by reducing energy density (ED) of a diet without producing short-term calorie restriction or feeling hunger. There are several studies which showed the beneficial effects of low energy density diets on weight reduction. However, few studies discuses regarding the effects of such diets on weight maintenance.

Arm Intervention/treatment
Experimental: Low energy dense
Diet of the LED group contained 30%fat, 15% protein and 55% carbohydrate. Most of the consumed carbohydrates in the LED diet group were fruits, vegetables and whole grains. In addition, this group received more servings of vegetables groups daily in the form of liquid diets or some menus contain more vegetables
 Other: low energy dense
This group received a diet appropriate with their weight in the form of low energy density diet
Other Name: LED

Other: diet
Calorie requirements of each subject were estimated based on resting energy expenditure (by the use of Harris-Benedict equation) and physical activity levels.
Other Names:
  • low energy dense
  • control
Experimental: control
In the group with a control diet, 35% of the energy was provided by fat, 15% by protein and 50% by carbohydrate
 Other: control
This group received a diet appropriate with their weight in the form of an usual diet regarding the energy density.
Other Name: usual

Other: diet
Calorie requirements of each subject were estimated based on resting energy expenditure (by the use of Harris-Benedict equation) and physical activity levels.
Other Names:
  • low energy dense
  • control
