BMI stands for body mass index. It is a measure of body fat based on height and weight. BMI is calculated by dividing weight in kilograms by height in meters squared.

A healthy BMI is in the range of 18.5 to 24.9. A BMI of 25 to 29.9 is considered overweight, and a BMI of 30 or higher is considered obese.

BMI is not a perfect measure of health. It does not take into account muscle mass, bone density, or body fat distribution. For example, athletes and people with a lot of muscle mass may have a high BMI even though they are not overweight. BMI is also not as accurate for people who are shorter or taller than average.

Being overweight or obese is a major risk factor for many chronic diseases, including heart disease, stroke, type 2 diabetes, and some types of cancer. Being overweight or obese can also lead to problems with mobility, sleep, and self-esteem.

There are several things you can do to improve your BMI, including:

• Eat a healthy diet.
• Exercise regularly.
• Get enough sleep.
• Manage stress.
