 Exercising to fight childhood obesity 
Most of the efforts to reduce childhood obesity have focused on reducing calorie intake. A new study indicates that increasing exercise is a better solution:


In a recent letter to the Physical Activity and Public Health On-Line Network, Professor Bernard Gutin, of the University of North Carolina wrote, "Recent evidence suggests that efforts to prevent child obesity are more likely to succeed if they emphasize vigorous physical activity rather than restriction of energy intake. The key principles are:

(1) studies of physical activity interventions should use as an outcome measure some index of fatness rather than weight;
(2) restriction of energy intake is contrary to the biologic needs of growing children; and
(3) vigorous exercise is more effective than moderate physical activity.

"Because of the time delay between the emergence of new evidence and its actual application, it will take years before we see publications of studies based on these ideas. In the meanwhile, I would be interested in hearing from people who are formulating or implementing interventions that focus on vigorous physical activity rather than restriction of energy intake."

 Dogfish Head Alehouse in Greenbriar 
According to the sign on the door of the Dogfish Head Alehouse in the Greenbriar Shopping Center, located on Route 50 just west of the Fairfax County Parkway, it will open this week. I stopped by yesterday and while I was there, several cars pulled up to read the sign. A private event was scheduled for later that day, always a good sign that the final bugs are being worked out and the place should open soon.

Unfortunately there is no bike parking available. In the photo you can almost make out the two bikes locked to trees just outside the restaurant. The lack of bike parking was brought to the attention of Dogfish earlier in the year and they were going to look into it. Now's the time.

 Cash for clunkers is a bad idea 
Initially it sounded good; get older, more polluting and less fuel efficient cars off the road and replace them with more fuel efficient cars. However, there is a downside. Here are a few of the points made by Discovering Urbanism's post C.A.R.S. will hurt the environment:

1. There will be more cars on the road.
2. Shifts in driving behavior compensate for fuel efficiency gains.
3. Manufacturing new cars adds more embodied energy.
4. Alternative modes of transportation will be discouraged.
5. The opportunity cost of $3 Billion means good programs are not happening. The $2 Billion that was authorized yesterday by Congress for the extension of C.A.R.S is being taken from money allocated in last year's stimulus bill for renewable energy programs. By instituting the C.A.R.S program, the federal government is opting to not institute programs that may actually reduce carbon output.
