What factors influence eating behaviors in adults with obesity?
Eating behaviors in adults with obesity are shaped by more than just food choices. Research shows that emotional states, stress, environment, and daily habits all play a role. Understanding these factors can help in developing more effective weight management strategies.
What the research says
A systematic review of nine studies involving 7,614 participants identified three main themes influencing eating behaviors in adults with overweight or obesity: psycho-emotional factors (such as negative emotions, impulsivity, and difficulty regulating emotions), socio-environmental stressors (including work demands and relationship issues), and maladaptive behavioral patterns (like eating too quickly or having irregular meal times) 1. These findings suggest that eating often serves as a way to cope with emotional or environmental strain rather than simply meeting nutritional needs 1.
Other research highlights additional influences. For example, a study on college students found that barriers to healthy eating include time constraints, stress, high cost of healthy food, and easy access to junk food, while enablers include meal planning and food knowledge 10. Timing of meals also matters: a study of 420 adults on a weight-loss program found that those who ate their main meal later in the day lost less weight, even when total calorie intake was similar 11.
Environmental and lifestyle factors are also important. Stand-alone digital lifestyle interventions have been shown to improve weight and dietary habits, indicating that technology can help address some behavioral factors 2. Additionally, wholegrain rye diets improved metabolic markers like inflammation and gut health, though they did not lead to significantly more weight loss than refined wheat diets 8.
What to ask your doctor
- How can I identify emotional triggers that lead to overeating or unhealthy food choices?
- What strategies can help me manage stress-related eating or impulsive snacking?
- Are there meal timing or planning approaches that might support my weight management goals?
- Could a digital lifestyle program or app be a helpful tool for me?
- How can I address environmental factors, like easy access to junk food, in my daily routine?
