Obesity refers to the state of being overweight, with excess body fat accumulation, which can lead to health problems such as diabetes, heart disease, and more. Choice A (heavy) is too broad and could refer to any type of physical weight, while choice B (body mass) refers to a numerical measurement of one's weight relative to their height and does not necessarily indicate if someone is overweight or not. Choice D (diabetes) is a health condition that can be caused by obesity, but it is not a term that specifically refers to being overweight.
