I have decided to try to knock out several birds with one stone (killing birds sounds bad). My proposal is a measure of myself: body measurements, weight and BMI as affected by the start of an exercise regimen at least three times a week. So the variables are exercise/calories burned vs change in body dimensions or weight. I plan to walk on the treadmill at 2 mph at an 8% incline for 1 hour three times a week. I have hit a plateau, buthave not been consistent with the exercise. I want to see if exercising on a regular basis while maintaining the same diet will make a difference in my weight loss. The two variables I will be measuring are weight and BMI.

The parameters were calculated as follows:
Calories burned values were taken off my treadmill at the end of each workout. The values are measured in calories. The treadmill has inputs for weight and height that it uses to calculate the number of calories burned.

Average calories were calculated by taking the sum of three numbers for the week and dividing by three.

The r-squared value was calculated using Microsoft Excel, ad the r-value was found by taking the square root of the r-squared value.

BMI (body mass index) was calculated by the following formula: weight in pounds/height in inches X 703.


On average, I burned an extra 1268 calories per week, while maintaining a 1500-1800 calorie/day diet. In the course of six weeks, I lost a total of 8.2 pounds or an average of 1.3 pounds per week. The r-value for the graph data had a value of 0.9865, which means that there is a strong correlation between the exercise and weight loss. My BMI went down 1.2 points, which is good, but is still too high. A BMI of 22 seems a long way away. This experiment shows that although my weight loss had stopped with diet alone, I broke the plateau by adding regular exercise to the regimen. I have to say I hoped it would be more, but no one ever said it was easy.
