Final answer:
Obesity, measured by BMI, is increasing in prevalence. It can result in serious health issues, but weight loss may reduce these risks.
Step-by-step explanation:
Using Body Mass Index (BMI) as a measure, it has been demonstrated that obesity continues to increase in prevalence. Obesity is diagnosed in adults when their BMI, which is an estimate of body fatness, is greater than 30 kg/m². Obesity arises from various factors, including overeating, poor diet, and a sedentary lifestyle. It can lead to serious medical conditions such as coronary heart disease, type 2 diabetes, and hypertension. Research indicates that weight loss can help mitigate the potential complications associated with obesity.
