Final answer:
Obesity is a disease in which excess body fat has accumulated to the extent that it is likely to have negative effects on health. Being significantly overweight is one of the criteria for diagnosing obesity.
Step-by-step explanation:
Obesity is a disease in which excess body fat has accumulated to the extent that it is likely to have negative effects on health. It is commonly diagnosed based on the body mass index (BMI), which is an estimate of body fatness. Obesity is diagnosed in adults when their BMI is greater than 30 kg/m².
Being significantly overweight is one of the criteria for diagnosing obesity. When someone is significantly overweight, their body weight is much higher than what is considered healthy or normal. Obesity can have serious health consequences, such as an increased risk of developing coronary heart disease, diabetes, certain types of cancer, and other conditions. Therefore, the statement that obesity is the condition of being significantly overweight is true.
