The links between stress and eating are vast. We can read about the Relationships between Stress and Eating. We can learn about Predictor variables of stress, affect and food craving on goal-congruent eating. We can also learn about the Mechanisms of Stress-Induced Hyperphagia and Hypophagia. Here are some examples. Read on to discover what your connection is between stress and food. Keeping track of stress can be a powerful tool in your fight against food addiction.
Relationships between stress and eating
Studies have indicated that the relationship between stress and eating behavior is not necessarily a one-way street. While both stress and obesity are linked, the relationship between stress and food intake differs in different people. According to a survey by the American Psychological Association, 43% of people report using food as a coping mechanism with stress. In addition, eating while under stress increases the risk of developing early metabolic disease. Stress-related eating may also play a role in the increasing incidence of obesity in the US. In the survey, 73% of adult men and 64 percent of adult women are considered overweight or obese. In addition, women reported eating higher-fat and high-sugar foods when under stress than did men.
This study showed that anticipatory stress coping and goal-congruent eating behaviour were positively associated with eating behavior. Goal-congruent eating was positively associated with experiencing stress and feeling hungry or bored. But the relationship between stress coping and goal-congruent eating was not as straightforward. This study suggests that a more comprehensive understanding of this link would be required to understand the complex interplay between stress and eating.
Predictor variables of stress, affect and food craving on goal-congruent eating
Previous studies have shown that the relationship between food craving and food intake is mediated by coping abilities. However, these relationships are likely to be brief and fleeting. Moreover, there are differences between intra-day and day-level retrospective analyses. The findings also suggest that the effect of momentary stress on goal-congruent eating might be due to its direct effect on coping.
The relationship between negative affect and food intake was moderated by SSES (Social Self-Efficacy Scale). Participants with high SSES reported eating more on days with higher levels of stress, whereas those with low SSES scores did not experience a significant relationship between the two. Thus, both stress and food craving were significant predictors of goal-congruent eating.
Mechanisms of stress-induced hyperphagia
The physiological and behavioral aspects of stress-induced hyperphagia remain controversial, but it is generally accepted that increased food intake during stressful situations is a symptom of obesity. Stress-induced hyperphagia may play a role in obesity development, as it increases the reward potential of food. In a recent study, researchers identified a link between stress and increased food intake, a potential cause of obesity.
Stress can affect our eating behavior by activating orexigenic and anorexigenic hormones in the brain. Studies show that chronic stress alters sensory-specific satiety signaling and induces the production of glucocorticoids, hormones with central orexigenic properties. As a result, stress-induced hyperphagia has been associated with increased intake of palatable, high-calorie food.
Mechanisms of stress-induced hypophagia
Several studies have compared rats’ and mice’s feeding behavior in novel and anxiogenic environments. Novelty-induced hypophagia occurs when a new environment creates a conflict between the desire to feed and avoidance. In these studies, mice are habituated to a palatable liquid and given the opportunity to consume it twice. The mice were given the same palatable liquid in two test sessions, one in their home cage and the other in a novel cage chosen to be mildly anxiogenic. The difference score between the two sessions represents hyponeophagia.
Studies show that over 82% of the population changes their food intake during stressful situations. Hyperphagic individuals are defined as those who consume more food than normal, while hypophagic individuals eat less food. Research on stress-induced hypophagia focuses on the quality and quantity of the food consumed, and the sensitivity of the reward system in response to stress. In the case of chow-fed mice, a comfort feeding regimen enhances caloric intake in stressful situations. However, obese mice are resistant to acute stress-induced hypophagia.
