The Energy Usage of Physical Activity

Once we have computed a mathematically derived BMR for you (or tested you on a BMR tester), we then add in the caloric energy needs of your body as a result of "getting out of bed," moving around, and exercising. We call this the "Energy Level of Physical Activity"—also known as Daily Physical Activity Need (DPAN)—it requires an individualized computation of calories. Whether you sit in an office all day, are a blue collar laborer a professional athlete, exercise intermittently or consistently—all modes of life have a direct effect on how many calories your body requires daily, over and above your BMR levels.

As my patient, we will look at what physical activities you are performing, covering literally every hour of your day (and night). When you exercise, I will assess both the "type" of your exercises and the intensity at which you perform them. Whether you are a heavy, medium, or light labore' this too has a bearing on the process of determining the exact amount of calories your body requires. I will assess the rate at which you burn calories throughout the day during different activities using mathematical norms based upon calorimetry studies conducted on exercising and sedentary humans. When you sit down you'll burn so many calories, when you lift heavy objects, you'll burn so many calories and so on.
if you'd like to have this more directly assessed, there is new lab technology that allows us to more precisely monitor your caloric consumption during your daily routine. As part of your treatment, I can arrange for this procedure i

Once we've determined the specific calorie needs for your individual pattern of activity, then we can add this amount to your BMR. in our hypothetical case, as my patient we determined your BMR to be 1,500 calories per day. Your Daily Physical Activity Need was found to be another 600 calories per day, so the combined figure is 2,100 calories per day. in other words, your body requires 2,100 calories per day to sustain itself without any net weight gain or loss in and out of bed. But we 're not finished with the quantification process yet.
