Bike commuting weight loss

« previous entry | next entry »

This morning my scale indicated that I have lost a total of 51 pounds since I started bike commuting, and since I got the fancy fat monitoring scale the fraction of my total mass that is fat has gone down by 10%. Which means that most of that 51 pounds that I lost was actually fat. 50 pounds is about the same weight as 6 gallons of water. Those big heavy water cooler bottles are 5 gallons so one of those plus another gallon jug worth of weight that I'm not carrying with me everywhere I go any more. Based on what fraction of the weight I lost was fat, and how much fat I have to lose for the scale to tell me that I'm fit I have about 22 pounds left to lose. Based on my current weight loss rate that will be a little under 4.5 months from now.

I've also lost six inches around my waist, and gone from wearing XXL shirts to large, and sometimes medium. Most of my clothes don't fit any more. I think I will try to sell a lot of them.

Awesome job!

Note that there is a (sort of) negative feedback loop operating here- as your body loses weight, it spends less energy just moving around- so your final approach to your intended weight may be slower than the initial rate of weight loss. This isn't an idea that I have specific empirical backing for, but it seems to follow simply enough from plausible assumptions. So if such a slowdown happens, I hope you aren't discouraged. You've done a great job so far.

Weight loss slowdown?

I seem to be compensating for that by biking more. When I started I couldn't even ride to work, and home on the same day. I would ride the bus for a few days in between. Took me 3, and a half months before I could do it both ways every workday of the week. But I would bike home, and then drive to get dinner, and I would drive on the weekends too. I keep decreasing how much I drive, and biking longer distances with more hills at a faster pace. As the weather gets worse I'm going to be carrying extra clothes with me (more weight), and fighting storm winds. I don't think I will slow down the weight loss for a while still because as I become more capable I just push myself harder.

congrats on staying motivated and los! I bike/MAX commuted yesterday, and then I fell off the wagon today (didn't have enough time to make it before a morning meeting).
