Biological, psychological, and social variables interact to affect obesity and mental health.

The association between obesity and mental health is complex, involving biological, psychological, and social factors. Examining these factors' interactions:

Hormonal Regulation: Leptin, ghrelin, and cortisol affect obesity and mental health. Neurotransmitters: Serotonin and dopamine imbalances can cause mood disorders and affect appetite.

Stress, worry, and despair can cause emotional eating. Coping with emotional eating can cause weight gain.

Cognitive factors: Food, weight, and body image thoughts, beliefs, and attitudes can affect eating and mental health.

Cultural perceptions toward body size and shape can influence society standards and stigma. Obesity stigma can affect self-esteem and mental health.

Environmental Factors: Access to good food, physical activity, and the built environment might affect obesity and mental health.

Eating Patterns: Food types and amounts effect weight and mental health. Coping Mechanisms: Substance use and avoidance can affect obesity and mental health.

Effective obesity and mental health interventions require understanding the intricate interaction of these variables. Multidisciplinary techniques that integrate biological, psychological, and social variables frequently improve well-being. 

Be on the lookout for any specific alterations that may occur.
