Final answer:

Step-by-step explanation:
Obesity is characterized by high amounts of body fat in relation to overall lean body mass. It is typically the result of excess caloric consumption and/or inadequate energy expenditure. When people consistently consume more food energy than they need, the excess calories are stored as fat, leading to weight gain and obesity.
Excessive body fat accumulation can negatively affect health, increasing the risk of various medical conditions such as heart disease, type 2 diabetes, high blood pressure, stroke, and certain types of cancer. Lifestyle changes, including a balanced diet and regular exercise, are important for controlling body fat accumulation and maintaining a healthy weight.
