BMR Calculator

This is a free BMR Calculator. It will calculate your Basal Metabolic Rate (MBR), i.e. the calories you are going to burn if you just stay in bed all day. Your BMR depends on your gender, weigh, height, and age. It decreases when your age increases, which means the older you get the harder it becomes to stay slim (unless you excercise or keep diet).
