It's Just a Number

Throughout this weight loss journey, it occurred to me that we tend to get hung up on numbers. My number is 40. That was the waist size I wanted to avoid. Or, when I gained weight, the number I wanted to get under. That number gave me my identity. If my waist size was over 40, too fat. Size 38, doing great. This is an arbitrary number. I have child bearing hips. So, a waist size of 40 gave no indication of my fitness, or even how I looked. I have no idea whether I was overweight when my waist was 40. I was too caught up in the number to be concerned with how I looked. In fact, I look back at pictures when I was younger, and had a waist size of 40, and I can't believe I was that thin. Although I realize this is a false number, I still want to get to a size 38.

Even should I reach size 38, that isn't the telling number anymore. Today, everyone is caught up in BMI. BMI is Body Mass Index. This is determined purely by your height. I have no idea about the science behind this number, but I believe it is bunk. According to whoever came up with this scale, a healthy BMI is between 18.5 and 25. A 6'1" male such as me should be less than 189 pounds. I don't even remember when I weighed 189 pounds. It certainly is not a good indication for athletic people that are muscular. Perhaps when I get anywhere close to that number I will reevaluate and determine BMI is a proper index.

The numbers that I am most interested in is blood pressure and cholesterol. I also pay attention to my percentage of fat. I would like to get this number under 22%. I am a long way away right now. It will be interesting to see whether BMI and body fat are comparable numbers. I will certainly let you know.

    Seriously Brian, if you don't know the science how can you believe this is pure bunk? On what basis do you rationalize that BMI is completely worthless?
