Which condition is defined by excessive accumulation of body fat, with a BMI above 30?

The condition characterized by an excessive accumulation of body fat, as defined by a Body Mass Index (BMI) of over 30, is obesity. Obesity is often associated with various health risks, including cardiovascular diseases, diabetes, and certain types of cancer. It signals a need for lifestyle changes, including dietary adjustments and increased physical activity, to mitigate these risks.

In contrast, the term overweight refers to individuals with a BMI between 25 and 29.9, indicating they have more body weight than is considered healthy, but not to the extent classified as obesity. Overtraining refers to a state of fatigue or decreased performance due to excessive training without adequate rest, which is unrelated to body fat percentages. Underweight describes individuals with a BMI below 18.5, indicating insufficient body weight in relation to height, and is also distinct from obesity. Understanding these definitions is important for recognizing different health statuses and their implications for fitness and overall health.
