You don't consider someone obese simply because they seem to have extra weight. There's a difference between being overweight and being obese. People are obese only when they have a body mass index (BMI) of 30 or more. A BMI between 25 and 29.9 is classified overweight, while ideal weight is between 18.5 and 24.9.
It's easy to calculate your BMI on your own. You could either visit an online BMI calculator or do it manually. For the manual calculation, multiply your weight in pounds by 703, then divide the number twice by your height in inches.
For example, if you weigh 250 pounds and are 70 inches tall, your BMI is (250×703÷70÷70) 35.9.
