Obesity is often framed as a personal failure. Medicine sees it differently: as a complex, chronic condition influenced by biology, environment, behaviour, sleep, stress, and food systems. This difference in framing determines whether people receive shame — or effective care.

Scientific evidence shows that weight regulation is tightly controlled by hormones that influence hunger, satiety, and energy use. When these systems are disrupted, sustained weight gain becomes biologically reinforced, not simply a matter of willpower.

Insulin resistance: the metabolic trap

Insulin resistance occurs when cells respond poorly to insulin, forcing the body to produce more. High insulin levels promote fat storage and make fat loss harder. This process links obesity, type 2 diabetes, high triglycerides, and fatty liver disease.

Why “eat less, move more” is incomplete

While calorie balance matters, it ignores drivers such as ultra-processed foods, liquid sugar, poor sleep, chronic stress, and medications. It also ignores the fact that the body adapts to weight loss by increasing hunger and reducing energy expenditure.

The health risks tied to obesity

• Type 2 diabetes
• Hypertension and heart disease
• Stroke
• Joint disease
• Fatty liver disease
• Sleep apnea

What effective weight management actually includes

• Nutrition patterns that stabilise blood sugar.
• Consistent physical activity, not punishment exercise.
• Sleep optimisation.
• Stress management.
• Medical evaluation when lifestyle alone is insufficient.

Bottom line: Obesity is a disease, not a defect. Treating it seriously — and early — reduces stigma, improves outcomes, and saves lives.
