Reproducibility of ad libitum energy intake with the use of a computerized vending machine system.

ABSTRACT:

Background

Accurate assessment of energy intake is difficult but critical for the evaluation of eating behavior and intervention effects. Consequently, methods to assess ad libitum energy intake under controlled conditions have been developed.

Objective

Our objective was to evaluate the reproducibility of ad libitum energy intake with the use of a computerized vending machine system.

Design

Twelve individuals (mean + or - SD: 36 + or - 8 y old; 41 + or - 8% body fat) consumed a weight-maintaining diet for 3 d; subsequently, they self-selected all food with the use of a computerized vending machine system for an additional 3 d. Mean daily energy intake was calculated from the actual weight of foods consumed and expressed as a percentage of weight-maintenance energy nee
