| This experimental study investigated the influence that food types (solid, liquid, and amorphous), obesity, and training had on the accuracy of food portion estimations. A sample of 55 adults, divided into obese and non-obese groups, participated in a 20-minute training session on accurately estimating food portions. The outcome of the training was measured utilizing a pretest-posttest design. The pretest and posttest asked subjects to estimate food portion sizes of the food models provided. The results of the paired t-test indicated that training had a significant effect on the accuracy of estimation of solids and liquids (p = .001, p = 0.17), while weight status did not. However, food type did significantly affect accuracy of estimation (p < .001). |
