Final answer:
Being 20-30 percent over the ideal body weight for one's height is referred to as being overweight. BMI between 25 and 29.9 kg/m² indicates this condition, which precedes obesity and is linked to several health risks.
Step-by-step explanation:
The condition in which a person's body weight is 20-30 percent over the ideal body weight for their height is known as being overweight or pre-obesity. This is commonly assessed using the body mass index (BMI), which measures body fat based on height and weight. A BMI between 25 and 29.9 kg/m² indicates overweight status, while a BMI of 30 kg/m² or higher denotes obesity. Obesity can have numerous negative health effects, including an increased risk of type 2 diabetes, heart disease, and certain cancers.
