Story at-a-glance Obesity is not just about weight — it's a chronic condition that impacts organ function and metabolic health, requiring more precise diagnostic tools than body mass index (BMI) alone Many people with a normal BMI still suffer from severe metabolic dysfunction due to hidden fat accumulation Researchers are now pushing for definitions of "preclinical" and "clinical" obesity. Clinical obesity refers to instances where excess fat is actively harming organs or limiting daily function Effective strategies that will help address obesity include eliminating vegetable oils, improving insulin sensitivity with the right carbohydrates and fixing micronutrient deficiencies Strength training and walking help restore metabolic function by improving mitochondrial efficiency, reducing inflammation and shifting your body's energy balance toward muscle instead of fat storage
