Final answer:
Obesity is defined by the body mass index (BMI), which is a measure of a person's weight divided by height squared. The normal BMI range is between 18 and 24.9 kg/m². Overweight is a BMI of 25 to 29.9 kg/m², and obesity is a BMI greater than 30 kg/m². Losing weight can help reduce or reverse the complications associated with obesity-related health conditions.
Step-by-step explanation:
Obesity is defined by the body mass index (BMI), which is a measure of a person's weight in kilograms divided by height in meters squared. The normal, or healthy, BMI range is between 18 and 24.9 kg/m². Overweight is defined as a BMI of 25 to 29.9 kg/m², and obesity is considered to be a BMI greater than 30 kg/m².
Obesity can arise from a number of factors, including overeating, poor diet, sedentary lifestyle, limited sleep, genetic factors, and even diseases or drugs. Severe obesity (morbid obesity) or long-term obesity can result in serious medical conditions, including coronary heart disease, type 2 diabetes, endometrial, breast, or colon cancer, hypertension, dyslipidemia, stroke, liver disease, gall bladder disease, sleep apnea or respiratory diseases, osteoarthritis, and infertility.
Research has shown that losing weight can help reduce or reverse the complications associated with these conditions.
