Hunger; Obesity


The purposes of this study were to test the validity of previous observations that obesity was a factor in lack of sensitivity to internal clues to hunger and to compare the difference between two methods, consumption method and taste reaction method, which were used to assess sensitivity to internal clues to hunger. The subjects were two groups of female college students, 109 participating in the consumption method and 199 in the taste reaction method. Their degree of obesity was determined both by triceps skinfold thickness and by height-weight relationship. Both methods involved comparing a subject's behavior in the fasted and fed states. In the consumption method the observed behavior was the amount of croutons voluntarily consumed while rating them. The taste reaction method utilized the subject's reported reaction to a series of sugar solutions. Thus, the measure of sensitivity to internal clues to hunger was the difference in grams of croutons in one case and the difference in ratings of sugar solutions in the other. Analysis of variance of measures of sensitivity among groups varying in fatness failed to show significant differences with either method. Nor did chi-square tests reveal any significant difference in the frequency of varying degrees of sensitivity to internal clues to hunger. Correlations between measures of sensitivity and skinfold thickness were very low and insignificant.
