Investigating the effects of negative-calorie diet compared with low-calorie diet under exercise conditions on weight loss and lipid profile in overweight/obese middle-aged and older men.

Background/aim: Negative-calorie diets (NCDs) are among the popular dieting guides for weight loss; however, there is still little knowledge about this method. The present study aimed to determine the effects of a NCD supplemented with exercise on weight loss and lipid profile, and to compare its efficiency with low-calorie diets (LCDs) with exercise among elderly adult men with abnormal weight gain.

Materials And Methods: Participants included sedentary men (aged 45-75 years) who were overweight or obese (n = 37).
