The following is for yesterday.

15,920 steps. I ran intervals for only 1.78 miles burning 190 calories, and walked for approximately one mile burning 64 calories. I walked in a very brisk pace up a steep hill for over a mile with a few short stops along the way. I calculated 92.5 calories for this through METs, considering BMR and it’s related adjustment value, and the slope of the hill. Too bad MET calculations cannot take into account fitness level. All of this totals 348 calories. This is definitely a conservative estimate. I may adjust this approach in the future to further stabilize my weight.

This makes for a target of 2648 calories. I have consumed 3241 calories. So this is a significant overage of about 600 calories. That quart of Pepsi did me in this time. I guess back to water. Still I do not think I have had an overage like this before. I will spread this over two days. So I will perform 300 calories of exercise each day watching more carefully what I eat those particular days. So it means more running for me today. Argh!

Interesting. Calculating daily calorie intake to maintain weight usually involves basically BMI and activity level. However, a more accurate calculation such as the Cunningham Equation includes additional factors like the percentage of body fat, and the crazy term “Thermic Effect of Food”, which is basically the amount of protien consumed per kg of body weight. This formula also has its own approach to determine two other factors, using such exotic terms as “Activity Thermogenisis”, and “Exercise Related Activity Thermogenisis”. All this means is that general daily activity level is considered along with calories due to exercise itself. No big deal here. Leave it to scientists to use rediculously opaque terms. One calculator that uses this information provides me with 2500 calories of daily intake to maintain weight excluding exercise. I think this is a bit high.
