Questions: A moderately active man weighing 175 pounds should consume maximum grams of fat per day from fat sources. (If an contains 9 calories per gram, what is the maximum number of grams of fat he should consume?)

To determine the maximum number of grams of fat a moderately active man weighing 175 pounds should consume per day, we need to follow these steps:

1. Determine Daily Caloric Needs:

   • For a moderately active man, the general guideline is to multiply his weight in pounds by 15 to estimate his daily caloric needs.
   • \( 175 \text{ pounds} \times 15 = 2625 \text{ calories per day} \)

2. Calculate the Recommended Fat Intake:

   • The American Heart Association recommends that 20-35% of daily calories come from fat.
   • We will calculate the maximum recommended fat intake, which is 35% of daily calories.
   • \( 2625 \text{ calories} \times 0.35 = 918.75 \text{ calories from fat} \)

3. Convert Calories from Fat to Grams:

   • Since 1 gram of fat contains 9 calories, we convert the calories from fat to grams.
   • \( \frac{918.75 \text{ calories}}{9 \text{ calories per gram}} = 102.08 \text{ grams of fat} \)

Therefore, the maximum number of grams of fat a moderately active man weighing 175 pounds should consume per day is approximately 102 grams.
