Regina is trying to cut back on her fat intake to help reduce total calorie intake and promote gradual weight loss. If she follows an 1,800-calorie meal plan and wants to achieve the Acceptable Macronutrient Distribution Range recommendation of total fat being between 20% and 35% of calories, how many grams of fat per day should she be eating

40-70 grams of fat per day .

Explanation:

As it is well known that one gram of fat gives 9 calories after the breaking into smaller units. Regina is following the 1800 calorie meal plan and according to the recommendation of total fat intake should be the 20 to 35 % of total calorie intake.

So, the 20% and 35% of 1800 are:

× = 360, and 1800 × = 630

and it is known as the 1 gram gives 9 calories so,

in case of 20 % the fat required will be : 360/ 9 = 40

in case of 35% the fat required will be : 630/9 = 70

Thus, the correct answer would be : 40 to 70 grams of fat per day.
