The dieting process can lead to a cycle of failure due to psychological and physiological factors: Dieting can lead to a cycle of failure due to psychological factors like body dissatisfaction and low self-esteem, and physiological changes that make weight loss harder
The dieting process can lead to a cycle of failure due to both psychological and physiological factors. Heatherton and Polivy's spiral model explains how dieting often begins in adolescence as a response to body dissatisfaction and low self-esteem. Initial success is often followed by weight regain, leading to feelings of personal deficiency and increased emotional distress. This distress makes dieters more vulnerable to disinhibited eating, and metabolic changes make weight loss even harder. The ironic processes theory adds that attempting to suppress thoughts of forbidden foods can actually make them more salient, leading to increased thinking about food and disinhibited eating. Central to this is the paradox of restrained eating diets, which require dieters to spend significant time, energy, and attention trying not to think about food. This leaves them with less cognitive capacity to resist external and internal food cues, leading to emotional frustration, distress, and ultimately, dieting failure. However, the spiral model also highlights that people who diet to maintain their weight rather than lose it may have higher self-esteem and greater success. Additionally, the role of ironic processes in dieting failure provides valuable evidence for the psychological aspects of dieting.
The Ironic Rebound Effect in Dieting: Labeling ourselves as dieters and focusing too much on food intake can sabotage weight loss, but individual differences like locus of control also play a significant role in dieting success or failure.
Simply labeling ourselves as dieters and focusing on our food intake can actually sabotage our weight loss efforts, a phenomenon known as the ironic rebound effect. However, the findings from Andriane Zettle's study may not be the sole determinant of dieting success or failure. The effects of ironic processes are short-term, while dieting requires long-term commitment. Therefore, other factors, such as individual differences like locus of control, likely play a more significant role in weight loss outcomes. For instance, those who believe they have control over their weight loss journey (internal locus of control) are more likely to succeed compared to those who feel it's beyond their control (external locus of control). Despite these explanations, Ogden (2010) argues that they don't fully explain why some people manage to lose weight despite being preoccupied with food. Thus, it's essential to consider multiple factors when predicting weight loss success or failure.
