BODY MASS INDEX - BMI

Excerpt from Omni Calculator sp. z o.o
By Mateusz Mucha and Aleksandra Zając, MD

The BMI calculator is a useful tool that measures whether you are overweight, underweight, or just right. Your weight alone is not enough to tell, as a tall, skinny man may easily weigh more than a short but round woman. The body mass index, or BMI, overcomes this problem by finding a ratio of your weight to your height, and returning a single number. This number will fit into a category on the scale of BMI ranges, which are defined as underweight, normal, overweight, and obese.

There are five basic ranges within the BMI scale:

Underweight = less than 18.5
Normal weight = 18.5 - 24.9
Overweight = 25 - 29.9
Obesity = 30 - 35
Severe obesity = 35 and more

*The results do not take into account individuals who are well muscled (such as body builders), or for those who have lost a significant amount of muscle (such as the elderly).

RESTING METABOLIC RATE

Excerpt from Omni Calculator sp. z o.o.
- By Filip Derma

RMR calculator is a tool which can provide you an answer to the question "how many calories do I burn at rest?"

RMR is the abbreviation of resting metabolic rate. This parameter tells how many calories are required by your body to perform the most basic functions (to keep itself alive) while resting. These essential functions are e.g.:

breathing
heart beating
circulating blood
basic brain functions
food digestion
sustaining the function of vital organs

RMR does not account for calories burned to support physical activity. Anything that we do through a day requires energy (calories) to be burned in addition to those used to support resting metabolic rate.
