Determining Daily Energy and Macronutrient Intake Goals
(30 points)

Estimating Daily Energy Requirements

If your weight is stable, your current daily energy intake is the number of calories you need to consume to maintain your weight at your current activity level. You can determine the number of calories you consume on a particular day by keeping a careful and complete record of everything you eat and then totaling the number of calories in all the foods and beverages you consumed. This calculation can be done by hand, by using a nutrition analysis software program, or by using one of several Web sites that perform this type of analysis; for example, go to SuperTracker.usda.gov and click on Food Tracker.

People often underestimate the size of their food portions, and so energy goals based on estimates of current calorie intake from food records can be inaccurate. You can also estimate your daily energy needs using the following formulas. To use the appropriate formula for your gender, you’ll need to plug in the following:

· Age (29) Weight (155) Height (5’7)

· Physical activity coefficient (PA) from the table below; to help estimate your physical activity level, consider the following guidelines: Someone who walks briskly for 30 minutes per day (or the equivalent) in addition to the activities in a sedentary lifestyle is considered “low active”; someone who walks briskly for 90 minutes per day is considered “active.”

Setting Intake Goals for Protein, Fat, and Carbohydrate

Once you have an estimate of your daily energy (calorie) needs, the next step is to set goals for daily intake from the three classes of macronutrients—protein, fat, and carbohydrate. You can allocate your total daily calories among the three classes of macronutrients to suit your preferences; just make sure that the three percentage values you select total 100% and that your values fall within the Acceptable Macronutrient Distribution Ranges (AMDRs) set by the Food and Nutrition Board of the National Academies. For example, you may choose targets of 15% of total daily calories from protein, 35% from fat, and 50% from carbohydrate. Fill in your percentage goals in the chart below:

To translate your own percentage goals into daily intake goals expressed in calories and grams, multiply the percentages you’ve chosen by your total calorie intake and then divide the result by the corresponding calories per gram. (Use the total daily calorie goal you calculated in the first part of this worksheet and the percentage goals you set in the table above.) For example, a fat limit of 35% applied to a 2200-calorie diet would be calculated as follows: 0.35 × 2200 = 770 calories of total fat; 770 ÷ 9 calories per gram = 86 grams of total fat. (Remember, fat has 9 calories per gram and protein and carbohydrate have 4 calories per gram.)

Macronutrients: Protein, Fat, Carbohydrate

To determine how close, you are to meeting your personal intake goals, keep a running total over the course of the day. For prepared foods, food labels list the number of grams of fat, protein, and carbohydrate; the breakdown for popular fast-food items can be found in an appendix of your text. Nutrition information is also available in many grocery stores, in published nutrition guides, in nutrition analysis software, and online. By checking these resources, you can track the total grams of fat, protein, and carbohydrate you eat and assess your current diet.
