Rigid and flexible control of eating behavior in a college population.

The objective of this study was to explore the relationship between rigid control (RC) and flexible control (FC) of eating behavior and their relationship to traditional weight, eating, and affective measurements in a large heterogeneous population. Participants were 639 underweight to obese male and female college students. Multiple regression analyses (MRA) revealed that high RC was associated with high Body Mass Index (BMI) and high Disinhibition (DIS), and high FC was associated with low BMI and low DIS in women. In men, high RC was associated with high BMI and high DIS, whereas FC was not related to BMI or DIS. Multiple regression analyses of BMI on RC and FC in the female subsample revealed that the control variables interact in such a way that the relationship between RC and BMI is stronger when FC is lower. In men, there was no interaction between these variables. This study is the first full replication of Westenhoefer's Gezugeltes Essen und Storbarkeit des Ebetaverhaltens: 2. Auflage. Gottingen: Verlag fur Psychologie () findings regarding RC and FC and their relationship to weight (BMI) and Disinhibition (DIS) in women. This is also the only second study to use the expanded, more reliable versions of the RC and FC scales. Overall, high RC in women and men was associated with greater eating and affective pathology.

What a difference a diet makes: towards an understanding of differences between restrained dieters and restrained nondieters.

Restrained eaters who are and are not dieting to lose weight have shown opposite eating regulation patterns in past research. To better understand these differences, restraint theory and the Three-Factor Model of Dieting was used to generate differential predictions about the mean and variability of restrained dieters (RDs) and restrained nondieters (RNDs) on the eating inventory Cognitive Restraint (CR) scale and the Restraint Scale (RS). Unrestrained nondieters served as a reference group. Eighty normal-weight female college students completed the CR, RS, and a measure of weight cycling. RDs, relative to RNDs, obtained higher and more homogeneous scores on the Cognitive Restraint, and higher and more heterogeneous scores on the RS. A post hoc analysis found that RDs had a much greater weight cycling history than RNDs. These findings are most consistent with the Three-Factor Model of Dieting, but also point to needed revisions both in this model and in traditional restraint theory.

Dieting: really harmful, merely ineffective or actually helpful?

Dieting has developed a negative reputation among many researchers and health care professionals. However, 'dieting' can refer to a variety of behavioural patterns that are associated with different effects on eating and body weight. The wisdom of dieting depends on what kind of dieting is involved, who is doing it, and why. Thus, depending on what one means by the term, dieting can be quite harmful, merely ineffective or actually beneficial. The present paper considers examples of all three. In particular, we argue that judgements about the desirability of dieting should consider the likely consequences to particular individuals of engaging in, or not engaging in, dieting behaviour.

Are you currently on a diet? What respondents mean when they say "yes".

Male and female university students were asked the questions "Are you currently on a diet to lose weight?" and "Are you currently on a diet to maintain your weight?" Respondents were asked to clarify positive responses by listing weight-control behaviors in which they were engaged. Responses were coded into 12 categories of dieting methods. Results indicated women and men who diet to lose weight engage in a wider variety of weight-loss behaviors than those engaged in dieting to maintain weight. Findings further indicated differences in dieting methods between individuals dieting to lose weight as opposed to dieting to maintain weight.
