Dietary Choice in Active Older Adult Women

Study Overview
=================
Brief Summary
-----------------
The present study aimed to determine the effects of negative-calorie diet supplemented with exercise, on weight loss and lipid profile, and to compare its efficiency with low-calorie diet with exercise among elderly adult women with abnormal weight gain.

Detailed Description
-----------------
Background: Negative-calorie diet is among the popular dieting guides for weight loss; however, there is still little knowledge about this method. Objectives: The present study aimed to determine the effects of negative-calorie diet supplemented with exercise, on weight loss and lipid profile, and to compare its efficiency with low-calorie diet with exercise among elderly adult women with abnormal weight gain. Material and Methods: Participants included sedentary women (age 45-75 years) with overweight or obesity (n=111). They were randomly divided into two groups including negative calorie diet with exercise, and low-calorie diet with exercise. Of all 111 participants, 90 persons completed the treatment. The weight assessment parameters including change in weight and body composition, blood sample tests were performed pre- and three month post-intervention.
