Body mass index (BMI)
BMI is a useful measure of overweight and obesity. It is calculated from your height and weight. BMI is an estimate of body fat and a good gauge of your risk for diseases that can occur with more body fat. The higher your BMI, the higher your risk for certain diseases such as heart disease, high blood pressure, type 2 diabetes, gallstones, breathing problems and certain cancers.
BMI range for adult men and women:
- Under 18.5 – you are considered underweight and possibly malnourished.
- 18.5 to 24.9 – you are within a healthy weight range for young and middle-aged adults.
- 25.0 to 29.9 – you are considered overweight.
- Over 30 – you are considered obese.
BMI figure may not be accurate. BMI formula in fact will overestimate the amount of body fat for body builders, some high-performance athletes and pregnant women and underestimate the amount of body fat for the elderly, and for people with a physical disability, who are unable to walk and may have muscle wasting.
Basal metabolic rate (BRM)
BRM is the number of calories required to keep your body functioning at rest, also known as your metabolism. Our values are based on the Mifflin - St. Jeor equations.
To determine the total daily calorie needs, the BMR (calculated with Mifflin - St. Jeor equations) has to be multiplied by the appropriate activity factor (lifestyles).
- Sedentary: little or no exercise;
- Lightly active: light exercise/sports 1-3 days/week;
- Moderately active: moderate exercise/sports 3-5 days/week;
- Very active: hard exercise/sports 6-7 days a week;
- Extra active: very hard exercise/sports and physical job.
The formula of Lorentz is the most simply and frequently applied method for calculating the theoretical ideal weight, being taken as a reference in several clinical studies. Lorentz formula does not take into account a person’s age and structural features of the body and it can be applied only for groups of age older than 18 years.
