>People get fat for two reasons. First is that people don't pay attention and gain weight by eating too much. This largely happens unconsciously, and with the food out there today, it can happen pretty easily. The second is that stress deprioritizes health. ... When people choose to lose weight and fail, it is always because of stress.

This premise is incorrect.

Medical conditions like Cushing's syndrome, hypothyroidism, polycystic ovary syndrome, chronic inflammation, sleep apnea, adrenal fatigue, Hashimoto's disease, low testosterone, poor gut health, Syndrome X, and insulin resistance, can cause weight gain or resistance to weight loss.

Essential medication like hormonal birth control, antidepressants, beta blockers, treatments for diabetes, antipsychotics, anti-epileptic medication, antihistamines, corticosteroids, and hormone replacement therapy, can cause weight gain or resistance to weight loss.

Difficulty in weight loss is not always because of stress, and weight gain isn't always because of "eating too much" or "stress."
