BMI ranges are used to classify a person’s weight as underweight, healthy, overweight, or obese. The ranges are based on a person’s height and weight, and they take into account age and gender.


  • BMI < 18.5

People with a BMI below 18.5 are considered underweight. This means that they have a lower than average amount of body fat. Underweight people may be at risk for health problems such as osteoporosis, anemia, and low immunity.

Healthy weight

  • BMI 18.5-24.9

People with a BMI in the healthy range have a normal amount of body fat. This is the range that is associated with the lowest risk of chronic diseases such as heart disease, stroke, type 2 diabetes, and some types of cancer.


  • BMI 25-29.9

People with a BMI in the overweight range have a higher than average amount of body fat. They are at increased risk for chronic diseases such as heart disease, stroke, type 2 diabetes, and some types of cancer.


  • BMI 30 or higher

BMI Limitations and Considerations

While BMI provides a general idea of body weight, it does have limitations. It does not take into account factors such as muscle mass, bone density, or distribution of fat. Thus, it may not be accurate for certain individuals, such as athletes or pregnant women.

Assessing Health Risks

In this section, we’ll delve into the health risks associated with different BMI categories. We’ll highlight the potential implications of being underweight, overweight, or obese, and emphasize the importance of maintaining a healthy BMI for overall well-being.

People with a BMI of 30 or higher are considered obese. They have a much higher than average amount of body fat and are at very high risk for chronic diseases such as heart disease, stroke, type 2 diabetes, and some types of cancer.

It’s important to remember that BMI is just one measure of health. It’s important to also consider other factors, such as your waist circumference, blood pressure, and cholesterol levels.

Tips for Improving BMI

To help readers take proactive steps towards improving their BMI and overall health, we’ll provide practical tips and strategies. These may include guidance on healthy eating habits, exercise routines, and lifestyle changes that can contribute to a healthier BMI range.

  • Eat a healthy diet. This means eating plenty of fruits, vegetables, and whole grains. It also means limiting processed foods, sugary drinks, and unhealthy fats.
  • Be physically active. Aim for at least 150 minutes of moderate-intensity exercise or 75 minutes of vigorous-intensity exercise each week.
  • Make gradual changes. Don’t try to change too much too soon, or you’re more likely to give up. Start by making small changes to your diet and exercise routine, and gradually increase them over time.
  • Be patient. It takes time to lose weight and improve your BMI. Don’t get discouraged if you don’t see results immediately. Just keep at it, and you will eventually reach your goals.
