Your child's resting metabolic rate (RMR) can be measured via an indirect calorimetry breath test. RMR is the number of calories one's body burns if he/she did not move all day; it is the minimum number of calories the body needs to support its basic physiological functions. Your RMR is usually 60-75% of your total daily calorie expenditure. RMR increases as the amount of lean body mass increases.
We can use your child's RMR to determine exactly the maximum number of calories your child can eat each day and still lose or maintain his/her weight. This allows your child to lose weight without feeling deprived. It also takes the "guesswork" out of the equation; if you follow the plan, your child will lose (or maintain) weight.
Your child's RMR can also be used to compare his/her metabolism to what is average for his/her age, height, weight, and gender. Many people blame their "slow" metabolism for their weight gain; this test will determine if your child's metabolism is slower than average.
