The purpose of a BMI is to give you an idea of how much body fat you have in relation to your weight and height. It is measured by taking your weight in kilograms and dividing it by your height in square meters. A value greater than or greater than 30 means that you are overweight. A reading equal to or greater than 40 indicates severe obesity.
Although most 20-year-olds don’t care much about their health, studies show that the lifestyle and health choices we make in our third decade of life have a dramatic impact on our health.
One of the most popular methods for calculating an ideal weight range is the body mass index (BMI). A result between 18.5 and 24.9 means that you are in the normal weight range for your height. If the result is below 18.5, you are underweight. Between 25 and 29.9 you are considered overweight.

Your Body Mass Index, or BMI, is the ratio of your weight to your height. The ideal is a BMI of 2025. 2,530 are overweight and over 30 are overweight. If your BMI is below 18.5, you are considered underweight. With a BMI of 18,520 you are slightly underweight and can no longer afford to lose weight.
Being underweight is not good for you. Nutritional Deficiencies: If you are underweight, you are unlikely to have a healthy, balanced diet, which can lead to a lack of the nutrients your body needs to function properly. Calcium, for example, is important for maintaining strong and healthy bones.
Teens can have a high BMI if they are gaining weight or have a lot of muscle, not excess fat. Underweight: BMI is less than the 5th percentile for age, gender, and height. Healthy weight: BMI is equal to or greater than the fifth percentile and less than the 85th percentile for age, gender, and height.
Causes. A person may be underweight due to genetic factors, poor nutritional metabolism, lack of food (often due to poverty), medications that affect appetite, illness (physical or psychological), or an eating disorder.
If a person has a high metabolism, they may not gain weight even if they eat high-energy foods. Frequent physical activity. Athletes or people who train a lot, such as runners, can burn significant amounts of calories, resulting in reduced body weight.
