Your body mass index, or BMI, is a simple calculation using your height and weight that can help you determine if you’re at a healthy weight. BMI is a screening tool that can help you determine if you have a healthy weight. It is not a diagnosis of obesity or any other health condition. Your doctor can help you determine if your BMI is in a healthy range and recommend ways to improve it if it isn’t.
BMI is a quick and easy way to estimate your body fat content. It is calculated by dividing your weight in kilograms by your height in meters squared. A BMI of 25 or higher is considered overweight, while a BMI of 30 or higher is considered obese. However, BMI is not a perfect measure of health. It does not take into account muscle mass or body composition. This means that some people who are considered overweight or obese by BMI may actually be in good health.
If you are concerned about your weight, talk to your doctor. They can help you determine if you are at a healthy weight and recommend ways to improve your health.

BMI is a useful tool for assessing your weight status, but it's not the only factor to consider when evaluating your overall health. Talk to your doctor about your BMI and other health factors to determine if you're at a healthy weight.
Simple calculation
Calculating your BMI is simple. All you need is your height and weight.
- 1. Convert your height to meters.
To do this, divide your height in inches by 39.37.
- 2. Square your height in meters.
For example, if your height is 1.75 meters, you would square it to get 3.0625.
- 3. Divide your weight in kilograms by your height in meters squared.
For example, if your weight is 70 kilograms and your height is 1.75 meters, you would divide 70 by 3.0625 to get a BMI of 22.8.
- 4. Interpret your BMI.
A BMI of 18.5 to 24.9 is considered normal. A BMI of 25 to 29.9 is considered overweight. A BMI of 30 or higher is considered obese.
Here is a simple formula you can use to calculate your BMI: BMI = weight (kg) / [height (m)]2 For example, if you weigh 70 kilograms and are 1.75 meters tall, your BMI would be: BMI = 70 / (1.75)2 = 22.8 This means that you are at a healthy weight.
Height and weight
Your height and weight are the two most important factors in calculating your BMI. BMI is a measure of your weight in relation to your height. This means that people who are taller or shorter than average will have different BMIs than people of average height.
- Taller people generally have higher BMIs than shorter people.
This is because they have more mass to distribute over their height. For example, a man who is 6 feet tall and weighs 200 pounds will have a higher BMI than a man who is 5 feet tall and weighs 200 pounds.
- Heavier people generally have higher BMIs than lighter people.
This is because they have more mass to distribute over their height. For example, a woman who weighs 150 pounds will have a higher BMI than a woman who weighs 100 pounds.
- BMI is not a perfect measure of health.
It does not take into account muscle mass or body composition. This means that some people who are considered overweight or obese by BMI may actually be in good health.
- BMI is a useful tool for assessing your weight status.
It can help you determine if you are at a healthy weight and identify any potential health risks associated with your weight.
If you are concerned about your weight, talk to your doctor. They can help you determine if you are at a healthy weight and recommend ways to improve your health.
Overweight or obese
A BMI of 25 or higher is considered overweight, while a BMI of 30 or higher is considered obese. People who are overweight or obese are at an increased risk for a number of health problems, including:
- Heart disease
Obesity is a major risk factor for heart disease, the leading cause of death in the United States.
- Stroke
Obesity is also a major risk factor for stroke, the fifth leading cause of death in the United States.
- Type 2 diabetes
Obesity is the leading cause of type 2 diabetes, a chronic disease that affects how your body turns food into energy.
- Cancer
Obesity is linked to an increased risk of several types of cancer, including breast, colon, and endometrial cancer.
If you are overweight or obese, talk to your doctor about ways to lose weight and improve your health. Even a small amount of weight loss can have a big impact on your health.
Not perfect measure
BMI is not a perfect measure of health. It does not take into account muscle mass or body composition. This means that some people who are considered overweight or obese by BMI may actually be in good health.
- Muscle mass
People who have a lot of muscle mass may have a high BMI, even if they are not overweight or obese. This is because muscle weighs more than fat.
- Body composition
People who have a high percentage of body fat may have a high BMI, even if they are not overweight or obese. This is because fat takes up more space than muscle.
- Age
BMI can also be affected by age. As people get older, they tend to lose muscle mass and gain weight. This can lead to a higher BMI, even if they are not overweight or obese.
- Race and ethnicity
BMI can also be affected by race and ethnicity. For example, Asian people tend to have a lower BMI than white people, even if they have the same amount of body fat.
If you are concerned about your weight, talk to your doctor. They can help you determine if you are at a healthy weight and recommend ways to improve your health.
Muscle mass
Muscle mass is an important factor to consider when interpreting your BMI. People who have a lot of muscle mass may have a high BMI, even if they are not overweight or obese. This is because muscle weighs more than fat.
For example, a bodybuilder who weighs 200 pounds and has a BMI of 27 would be considered overweight. However, this person may actually be very healthy and fit. Their high BMI is due to their large amount of muscle mass, not body fat.
If you are concerned about your weight, talk to your doctor. They can help you determine if you have a healthy amount of muscle mass and body fat.
There are a few things you can do to increase your muscle mass and improve your overall health:
- Strength training
Strength training exercises, such as lifting weights or doing bodyweight exercises, can help you build muscle mass. Aim for at least two strength training sessions per week.
- Eat a healthy diet
Eating a healthy diet that is rich in protein, carbohydrates, and healthy fats can help you fuel your muscles and support muscle growth.
- Get enough sleep
Getting enough sleep is essential for muscle recovery and growth. Aim for 7-8 hours of sleep per night.
By following these tips, you can increase your muscle mass and improve your overall health.
Body composition
Body composition is another important factor to consider when interpreting your BMI. Body composition refers to the percentage of muscle, fat, and bone in your body. People who have a high percentage of body fat may have a high BMI, even if they are not overweight or obese. This is because fat takes up more space than muscle.
For example, a person who weighs 150 pounds and has a BMI of 25 would be considered overweight. However, if this person has a high percentage of muscle mass and a low percentage of body fat, they may actually be very healthy. Their high BMI is due to their large amount of muscle mass, not body fat.
There are a few things you can do to improve your body composition:
- Eat a healthy diet
Eating a healthy diet that is rich in fruits, vegetables, and whole grains can help you maintain a healthy weight and body composition.
- Get regular exercise
Getting regular exercise, including both cardio and strength training, can help you burn calories, build muscle mass, and improve your overall body composition.
- Get enough sleep
Getting enough sleep is essential for overall health and well-being. When you don't get enough sleep, your body produces more of the stress hormone cortisol, which can lead to weight gain and increased body fat.
By following these tips, you can improve your body composition and overall health.
Talk to your doctor
If you are concerned about your weight or BMI, talk to your doctor. They can help you determine if you are at a healthy weight and recommend ways to improve your health.
Your doctor may ask you about your diet, exercise habits, and family history of obesity. They may also perform a physical exam and order some tests, such as a blood test or a body composition analysis.
Based on the results of your evaluation, your doctor can develop a personalized weight loss plan for you. This plan may include changes to your diet, exercise routine, and lifestyle.
If you have a BMI of 30 or higher, your doctor may recommend weight loss surgery. Weight loss surgery is a major surgery that can help you lose weight and improve your health. However, it is important to note that weight loss surgery is not a magic bullet. You will need to make lifestyle changes to maintain your weight loss after surgery.
No matter what your weight or BMI, talking to your doctor is the best way to determine if you are at a healthy weight and to develop a plan to improve your health.
