Question

A patient is drinking 8 oz. of BOOST Plus three times a day. (Each 8oz bottle contains: 360 kcal, 14 g fat, 14 g protein, 45 g carbohydrate). What % of calories are being provided from fat? (fat = 9 kcal/gram, answer to the nearest whole %)

Answer 1

Each 8 oz. bottle of BOOST contains:

• Fat                     = 14 g
• Protein               = 14 g
• Carbohydrate    = 45 g

Total weight (fat + protein + carbohydrate) = 73 g

As, 1 g fat provide 9 kcal

1 g of carbohydrate provide 4 kcal

and, 1 g of protein provide 4 kcal

Therefore 8 oz. bottle of Boost provides the number of total calories can be calculated as

14 g of fat                          = 14 x 9 kcal        = 126 kcal

14 g of protein                  = 14 x 4 kcal        = 56 kcal

45 g of carbohydrate       = 45 x 4 kcal       = 180 kcal

Total calories = 126 + 56 + 180 kcal

= 362 kcal

It is given that 8 oz. bottle contain 360 kcal.

Therefore, % of calories provided by fat can be calculated as:

= (126/360) x 100

= 0.35 x 100

= 35 %

Therefore, the fat present in the 8 oz. bottle of BOOST provides approximately 35% of the calories of the total calories provided by the 8 oz. bottle of BOOST.

Hence, the answer must be 35%
