The web site transitions several years of research that relates obesity, transportation, and caloric intake into a user-friendly web site for everyone to enjoy.

The United Stated Department of Agriculture (USDA), Center for Nutrition Policy and Promotion, reports estimated caloric needs based on gender, age, and physical activity level. However, the caloric intake you enter should be based on actual food consumption, which may differ from the needs estimated by the USDA. Driving habits should be based on your annual car usage. For example, a daily commute of thirty miles to and from work each day (i.e., 150 miles per week) would contribute 7,500 miles each year to your driving based on working 50 weeks per year; any additional travel would be added to this.

Our estimates of national average BMI are based on regression analysis of historical data. The allowed range of inputs for both caloric intake and driving habits are based on the range of national averages observed in these historical data, since our regression model may not be able to make reasonable estimates for inputs outside these ranges.

The results reported on the web site are for average Americans with the designated inputs. Any one person may have a higher or lower BMI if changes are made in their designated driving habits or caloric consumption.

The results reported on the web site are for average Americans, so any one person may not exactly match such an average individual. Therefore, the website provides no specific advice for losing weight nor medical advice related to such objectives. Please seek professional medical advice if you have health concerns related to obesity and physical exertion.
