Dehydrated or Obese?
With three different methods, my class measured each of our body compositions (it's only me and a classmate) in terms of fat mass and fat free mass. Test after test resulted in numbers that shocked me, mainly because of the descriptive words to which they correspond. These words can damage the body image I've carefully constructed since my dancing younger dancing days when the extra-large pinstripe pants bent their lines to emphasize my thighs. Confronting the mirror has become less of an exercise of mental strength, but how can my scientifically-trained mind ignore numbers?
Body Mass Index (BMI) indicated the percentage of mass on a person's body that is comprised of fat. In the most simple form, it estimates the percentage by plugging height and weight into a simple little formula. Several factors like age, gender, and activity level are neglected in that formula, so other ways of indirectly measuring fat mass were generated. The ones we studied today were the 3-point skin fold test using calipers, a scale-type bioelectrical impedance analysis (BIA), and an electrode-based BIA.
I bared my pasty, doughy belly and thighs in the name of learning how to measure skin folds. In this particularly mortifying method, one's fat is dug, pinched and pulled from the body. Next, I disrobed my feet for the scale BIA. This device not only measures weight, but also sends an electrical current into your lower body and measures the amount of resistance it meets (fat doesn't conduct as well as water). The scale has always been a natural foe. Finally, electrodes were stuck to my hand and foot to measure the resistance of the electrical current in the same way that the scale did. The information retrieved from this machine was entered into a program on a separate computer.
After all of these processes, my numbers ranged from 31-36% body fat. A percentage over 30% fat mass is classified as clinically obese.
My head doesn't seem to want to accept the classification. There could be lots of error; if one doesn't have enough water in their system, the reading could be higher than the actual percentage. With a low hydration level (which the scale also detected), my BMI could be reading too high. The skin folds test, however, doesn't rely on these factors.
I feel a sense of urgency to run to the gym and stay on the treadmill for hours or not eat for the next few days. This will ultimately accomplish more damage than benefits, yet I want to erase the label from my body. I feel the weight of the five letters more than I've felt the weight of the cells.
