Before and After Body Analysis

How did I do with with respect to weight loss? Let's look at pictures. This first one was taken on day 3 of the trip, just outside of Twisp, WA. The one below that was taken on day 26, just outside of Somerset, PA. As you can clearly see, I have become so thin that I no longer show up in digital photos.

Below are some actual before and after pictures taken on the first day of the trip (left) and the last day of the trip (right).

Back in May, I wrote a post about Body Mass Index and % Fat (BMI vs. % Fat). I concluded that BMI was a bad measure of health and that % body fat should be used instead.

So what does the math say?

Table 1.	Before	After
Weight	238	224
BMI	39.8	37.4
Fat %	23	18.6
Fat Free Mass	184	183
Min. Wt. at 7% BF	197	196.81

I lost 14 pounds in 30 days. I decreased my BMI by 2.6 points. I used to be classified as "obese" by this method. Am I still?

Table 2

Yep. In order to move out of the "obese" category, I need to weigh less than 180 lbs. If you look at table 1, my fat free body mass is 184 lbs. At that weight, I will have zero fat. Clearly the term obese is a mis-label for anyone with zero body fat. It makes me angry that my physicians have been using this completely misleading index to determine a healthy weight for me. The fact that life insurance companies also use this index is also maddening.

Let's see how I did on a % body fat basis. I went from 23 to 18.6%. On Table 3, below, that is from the high end of average to the low end of average. Clearly, I could still stand to lose some weight, but how much? I think my minimum should be 197 lbs (7% body fat). To be in the athletic range, I want to be no more than 13% fat which translates to about 208 lbs. Assuming I don't lose any muscle mass, that means I should lose about 16 lbs.

Table 3

If you're a real data junkie, you will have noticed that my fat free body mass went down by a pound (184 to 183). I suppose it is possible that I lost muscle mass. With the amount of exercise I was doing, I would have thought I would have been adding muscle. I did constantly crave protein (give me meat). Perhaps my body scavenged from unused muscles. I didn't cut any limbs off and my hair has negligible weight (as well as neglibible volume and incidence). My best guess is that this is random error, but I welcome any ideas about this.

To the Atlantic

From Chambersburg to Phoenixville, PA we went through a fair amount of rolling farmland. It's very scenic with a high concentration of solid biofuel waste (horse manure). We saw many Amish folks dressed in their best clothes on their way somewhere (it was a Wednesday). One buggy was really moving. I suspect that they were late. I didn't feel comfortable taking pictures of these deeply religious people--plus I was afraid that Harrison Ford might punch me.

If you want pictures of Amish, just do a google image search (Amish pictures).

For a deep understanding of the Amish, this educational video might be helpful:

The Amish grow a fair number of crops, among these are corn, soybeans, wheat, oats, and tobacco. I was surprised at just how much tobacco they grew.

They also grow about every kind of vegetable, cane fruit, tree fruit and flower that will grow in the climate. The desire to provide order to nature seems apparent in much of what they do.

The amish know how to use nature to beautify their homes.

We stayed with Doug & Lisa Jenkins in Phoenixville, PA. The food was amazing. Thanks for your hospitality. Doug was a 1992 graduate of Juniata College (my class) and Lisa was two or three years ahead of us (although she looks exactly the same as she did). Doug and I also went to the University of Wisconsin at Madison for graduate school.
