Obesity is a chronic disease driven by hypothalamic dysregulation of body fat mass set points, not by individual neglect of eating habits or exercise.

Stop blaming yourself for your weight. Your body is biologically defending a higher fat mass set point due to hypothalamic dysregulation. This is a chronic disease, not a moral failing. Effective treatment requires addressing this biology (e.g., via medications or surgery that target these pathways) rather than relying solely on willpower or calorie counting, which often fail because they trigger metabolic adaptation.

Such presumed personal choices do not constitute a disease, they are modifiable risk factors. On the other hand, if these external contributors, such as the environment of psychological state, are instead influencing expression of an innate biology, then the final common pathway to obesity is, instead, internal to the body and reflects disrupted physiology.
