I've been keeping to my New Year's Resolution of raising my walking schedule to twenty miles a week. I wasn't keeping track of my walking mileage before this, but it was probably averaging only about seven miles per week. I didn't make any plans on changing my diet for a couple of months, but was just going to focus on the increased exercise. I'm already feeling much better with the increased exercise. I've got more energy and am in a better mental and emotional spirit. But I haven't lost any weight and it's been over a month now!
But I do feel more toned, and though I didn't measure myself at the beginning, it's quite likely I'm losing a bit in inches around most parts of my body. My sister is trained as a dietician. She says they were told muscle is three times as dense as fat. Meaning a pound of fat takes up three times as much space as a pound of muscle. So she thinks I've added a little bit of muscle and have lost some fat. The scale doesn't show this difference at all, but if it's true, it would be a big improvement.
I've done over two hours of research on the web, trying to find the definitive answer for the muscle versus fat density question. (This is as good procrastination as any for delaying my walk today ;-)) There are a lot of conflicting answers out there. If anyone has a good online reference, and more encouragement for those of us who have started exercising but don't see the good results on their scales, please let us know!
There was a good article in the New York Times yesterday encouraging people to 
Michelle Obama looks really fit for her age. She just celebrated her 44th birthday last week. The highly publicized story is that she works out most weekday mornings on her treadmill, starting at 4:30am and is in bed by 9:30pm. She has two daughters aged 5 and 8. I'd be interested in getting more information about her actual workout routine, can anyone supply some good information?
