-squared value of .7033, suggesting that around 70.33% of the variation in overall meal acceptability could be explained by the nine food category predictors. The findings also suggested that the most influential food item on overall meal acceptability was the main dish followed by the side dish. For every unit increase in the acceptability score of the main dish on a 9-point hedonic scale, the overall meal acceptability increased by 0.324 points. The positive findings would be beneficial to food service providers in designing a vegetarian meal with high meal acceptability. By focusing on optimizing the acceptability of these two key categories, menu planners can effectively elevate customers' satisfaction of their meals.

Kuhns was the first to suggest that theories in science do not develop in small increments but rather in major leaps to paradigms that examine the same question through very different perspectives. Theories on the mechanism responsible for control of human food intake fall into Kuhn's description. This article describes how the two major theories of the control of food intake in humans, the Glucostatic Theory, and the Lipostatic Theory, showed initial promise as explanations, but later deteriorated with the slow accumulation experimental data. The locus of theories considered eating behavior as a part of physiological system that regulates the storage of energy on the body. We challenge this fundamental belief with data which suggests that we must be ready to accept a major change in the way we think about eating behavior if we are ever to decrease the prevalence of obesity.
