Basal metabolic rate (BMR)
- One's resting energy expenditure measured in the morning, at least 12 hours after the last meal.

* here is more information about BMR that I found.
- You expend energy no matter what you're doing, even when sleeping. Thus your Basal Metabolic Rate is the number of calories you'd burn if you stayed in bed all day - a tempting idea for some. If you've noticed that every year, it becomes harder to eat whatever you want and stay slim, you've also learned that your Basal Metabolic Rate decreases as you age. Likewise, depriving yourself of food in hopes of losing weight also decreases your BMR, a foil to your intentions. However, a regular routine of cardiovascular exercise can increase your BMR, improving your health and fitness when your body's ability to burn energy gradually slows down.

Resting metabolic rate (RMR)
- Energy expended by a person at rest in a thermally neutral environment and RMR is one the main contributing componenents of energy expenditure (around 70%)

* Hear is the another infomation about RMR.
- Your Resting Metabolic Rate (RMR) is the minimum number of calories your body needs to support its basic physiological functions, including breathing, circulating blood and all of the numerous biochemical reactions required to keep you alive. Your RMR is generally 60-75% of your total daily caloric expenditure.

Do you know how you measure your RMR? Here is the way...
For males
- 66+ (6.22 x weight (lbs)) + (12.7 x height (inches)) - (6.8 x age)
For females
- 655 + (4.36 x weight (lbs)) + (4.32 x height (inches)) - (4.7 x age)
