Calculate Your Basal Metabolic Rate and Body Mass Index (BMR & BMI)

                                                                                                           [bmibmr] BMI = Body Mass Index

A statistical measure which compares a person’s weight and height. Though it does not actually measure the percentage of body fat, it is used to estimate a healthy body weight based on a person’s height.
BMI Reference Table
per The World Health Organization:

BMR = Basal Metabolic Rate

Your BMR calculator generates the number of calories your body burns per day at rest. Your BMR with activity factor is the number of calories your body burns per day based on the activity factor you selected.

MET = The Metabolic Equivalent of Task

Metabolic Equivalent or MET, is a way of expressing the energy cost of physical activities. By convention 1 MET is considered the resting metabolic rate obtained during quiet sitting. MET values of physical activities range from 0.9 (sleeping) to 18 (running a 5.5 min/mile). MET is used as a practical means of expressing the intensity and energy expenditure of physical activities.
