          Use daily calorie totals from above to compare with the following

Daily caloric intake – well-balanced diet

Range

         2,800 largest servings

Formula of caloric intake for a desired body weight

Desired body weight (lbs.) x 10 (not active)

                                            x 20 (highly active)             = caloric intake to maintain desired weight
