Excellent! I just had someone ask me about this tonight. Now I can pass along this information. Thanks, Gale! By the by, my experience with the scales that measure body fat has not been good; we have one at my house, and last time I checked it said 30% (I'm actually just under 24%). I would advise seeking some kind of validation for the scale's measurement.

All great articles today. I was a sprinter in college and I think the lowest I got to with my body fat percentage was around 8%. I think if I got any lower than that my power would drop. RIght now though I'm trying my legs at distance running and I think I relate to the "starving athlete" article. I even have come to the point where I really have to watch my calories because otherwise I don't eat enough. Now I'm hoovering around 5-6% which seem really low, almost too low. Besides being a wimp in the cold all the time, has anyone else heard of down sides for a male to be at a low body fat for such a long period of time?

Great post Jeff and congrats on the weight loss. It takes discipline to change comfortable habits.

Jamie ~ Good question on the low body fat for males. I don't know of anything off the top of my head, I'll keep a watch.

I don't understand the comment on "lose of power". Of course you will lose power, but that doesn't mean you are losing speed, you need to measure Watts/kg to really understand where you are on the bike. I way less than 140, 5% body fat, have an FTP of 210, but I can go 22 miles per hour in a half iron man, probably more now. That's why they say be as lean and powerful as possible. You can check out "Training and Racing with Power Meter". There is a lot written about watts/kg now. Can't just measure power.

Niemsco ~
"Of course you will lose power" - not true. You can lose weight and not lose power.
You are correct, however, watts per kilogram (or pound) is the critical measure.
As a young adult I was obese. I am 5' 7" and I weighed 273lbs. I lost the weight and started racing bicycles as an adult at 165 lbs and about 12% bodyfat. Over the years I decided to drop weight and have found that I'm able to race my best at 145 lbs and a bodyfat of 4 - 5% (as measured by calipers and Tanita scale). I know I lost muscle in the process, but most of that was upper body mass which wasn't particularly useful on the bike. Regarding power, when I was heavier I could put out more watts for short bursts, but I couldn't climb well at all. I also found that I would cramp during long races. I think the cramping was partly due to adaptation, but also due to hauling my mass around for hours on end. As I lost weight my cramping has almost vanished and my sustained speed in the flats improved as did my climbing. As I've adapted to my smaller size and changed my focus from trying to get lighter and leaner to trying to get stronger at the same weight, I found my power to weight ratio has steadily improved.
My personal philosophy is to stay as lean as I can and still maintain my health and power. This philosophy is not without risk. If you plan to change your body composition, you should consult your doctor and if you get the go ahead, consult a dietitian for nutrition and a coach to help monitor performance. I would recommend not getting overly obsessed with your weight. Stay focused on your health and your performance. I hesitate to say this, but it is a real issue, keep in mind that another risk is developing and eating disorder. As Gale said, make changes gently and gradually. It took me almost 2 years to get from 273 to 165 and about a year to get from 165 to 145.
Getting and staying lean is a commitment in both time and mental energy but I've rewarded with better race results and sense of satisfaction. Besides, at age 41 I can see my abs. That's better than chocolate cake any day.
