Answer to Question 1
Look up the healthy weight for a person of your height (e.g., inside the back cover of the textbook). If your present weight falls within that range, use it for the following calculations. If your present weight falls outside the range, use the midpoint of the healthy weight range as your reference weight. Convert pounds to kilograms, if necessary (pounds divided by 2.2 equals kilograms). Multiply kilograms by 0.8 to get your RDA in grams per day. (Teens 14 to 18 years old, multiply by 0.85.)
