Interesting. I have been using my new activity watch. 5560 steps so far. This amounts to 642 calories for 4.5 miles. For over the first half, I really pushed myself, not briskly walking, but walking almost as fast as I could. The second half I walked briskly for a significant part of the time. The heart rate peaked at 150 bpm with the average of 122 bpm. This average is a bit low probably due to the second half of my walk. I know the heart rate is accurate since I wore a chest strap with a heart beat sensor.

I checked this out through various calorie burned calculators and the value comes out to be about 550 to 600. This does not take into consideration my fitness level. My measure of fitness level may be a bit off. It becomes more accurate over time. So these calories may be off some. I will have spaghetti and I want to have meatballs with my spaghetti. I need to kill about 100 calories to do this and remain lower than my target calories.

The short of it is I think I am now getting a handle on my diet to remain at my current weight. This is what counts.
