Today is weigh in day. It’s Saturday. I have no trips planned until June so this is a chance to get my weight loss on track. I can’t keep squandering these chances. If I want my health to spring forth speedily, then I have to coöperate. I can’t be that person who sits at the table with a large plate of spaghetti in front of him and say, “I need to lose some weight.”
I have a scale that uses bioelectrical impedance for measuring body fat. In one of the trivia questions on SparkPeople, it asked if these were accurate. The answer of course is no. Their explanation went like this:
“Special scales that use bioelectrical impedance (weak electrical signals) can estimate your body fat percentage. These scales can have a large margin of error (around 10% or more according to some studies). Plus, digital scales only measure fat levels in the lower body (the signal travels up one leg and down the other), so they don’t provide a full picture of the fat level of your entire body.”
I realize that there are many reasons for possible inaccuracy. The resistance in you feet changes daily or from time of day. I measured once in the afternoon and it was lower than in the morning. I even have one that you hold and it gives your body fat percentage. There is always a difference of three or so percent. One measures lower body and the other upper body.
For me, it’s not the number so much as the progress. My desire is to see the number drop, as well as the weight number. They should work in conjunction. Weight goes down, body fat percentage goes down.
I hope that I did well this week. I think the scale wants me to do well. Yeah right, what does it know?
