Count calories. Eat right.
But, you already knew that, didn’t you?
BMI is a basic health screening test that involves calculating the ratio of weight and height. Normal range (for both men and women) is 18.5 to 24.9. A BMI value of less than 18.5 means that the person is underweight, and a value of over 24.9 means overweight. A BMI value higher than 30.0 means the person in question is obese and is predisposed to many health risks such as diabetes, cardiovascular diseases, high cholesterol, depression, etc.
BMI is based on only two parameters. It is not a tool to determine ideal body weight or health risks. Muscles weight heavier than fatty tissues and so two people with different weights could have the same waist size. BMI of muscular people may not be accurate. Similarly, BMI cannot predict nutritional deficiencies. They need further medical screening. Note: These values are not applicable for infants and kids below 18 years of age.
