Question

zara is trying to cut back on her fat intake to help reduce total calorie intake and promote gradual weight loss. if she follows an 1800 - kilocalorie meal plan and wants to achieve the acceptable macronutrient distribution range recommendation for total fat (20 - 35% of calories), how many grams of fat per day should she be eating? multiple choice 40 - 70 grams of fat per day 40 - 75 grams of fat per day 360 - 630 grams of fat per day 47 - 82 grams of fat per day

Explanation:

Step1: Calculate lower - bound of fat calories

The total calorie intake is 1800 kcal. The lower - bound of fat as a percentage of calories is 20%. So the lower - bound of fat calories is $1800\times0.2 = 360$ kcal. Since 1 gram of fat provides 9 kcal, the lower - bound of fat in grams is $\frac{360}{9}=40$ grams.

Step2: Calculate upper - bound of fat calories

The upper - bound of fat as a percentage of calories is 35%. So the upper - bound of fat calories is $1800\times0.35 = 630$ kcal. Since 1 gram of fat provides 9 kcal, the upper - bound of fat in grams is $\frac{630}{9}=70$ grams.

Answer:

40 - 70 grams of fat per day
