Low Energy Dense, Weight Maintenance, Risk of Cardiovascular Disease

Phase 3

Completed

• Conditions: Body Weight Decreased
• Interventions: Other: low energy dense; Other: control; Other: diet

• Registration Number: NCT01659450
• Lead Sponsor: Isfahan University of Medical Sciences

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 .

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.

Low energy dense	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
