Which term describes a condition related to excessive body fat?

The term that describes a condition related to excessive body fat is "obese." Obesity is defined as having a body mass index (BMI) of 30 or higher, which indicates an excess accumulation of body fat that can negatively impact health. This condition is associated with various health risks, including heart disease, diabetes, and hypertension. Understanding obesity is crucial as it emphasizes the importance of maintaining a healthy weight for overall well-being.

In contrast, the other terms do not denote excessive body fat. "Thin" suggests an insufficient body fat percentage, while "healthy" and "fit" indicate states of well-being and physical fitness that do not inherently relate to body fat levels.
