Do severely overweight people get that way because their metabolism is slower than normal? Probably not according to a device which is called a metabolism monitor.
Instead, it suggests the more active you are, the more you can pump up your metabolic rate. "Which means that the majority of the patients that we see aren't metabolic cripples," says Dr. Mitchell Roslin, a Surgeon.
The metabolism monitor measures the carbon dioxide you breathe out to calculate your resting metabolic rate. Dr. Mitchell Roslin says the device shows metabolic rate is actually based on what you'd expect from age, gender, and weight.
For most people, he says resting metabolic rate is about two-thirds of the total calories burned during a day. But for couch potatoes, it might be 90% of your daily calories.
