Q. What exactly are the criteria for severe obesity? And why does this make dieting so much harder?
Severe obesity is generally defined as having a Body Mass Index (BMI) of 30–35 kg/m² or higher. It is not simply a matter of excess weight, but a state where your body's 'metabolic efficiency' has significantly declined. Excessive fat accumulation increases inflammatory markers and insulin resistance, reducing energy expenditure and often leading to a plateau where weight loss becomes extremely difficult despite your best efforts.
