Note the following information about William's diet. This
represents his usual intake and he is maintaining his weight.
Daily saturated fat intake = 40 grams
Daily unsaturated fat intake = 40 grams
Daily cholesterol intake = 260 mgs
Daily starch intake = 260 grams
Daily simple sugar intake = 140 grams
Daily fiber intake = 9 grams
Daily protein intake = 70 grams
Daily sodium intake = 3500 mgs
Approximately how many kcalories per day is William consuming?
2040
1560
3840
2600
2240
The option 2600 is the right answer
* Daily saturated fat intake = 40 grams
1 gram fat produces= 9 calories .
therefore the calorie from 40 grams of saturated fat = 40 x 9 = 360 kcal
* Daily unsaturated fat intake = 40 grams
1 gram fat produces= 9 calories .
therefore the calorie from 40 grams of unsaturated fat = 40 x 9 = 360 kcal
* Daily cholesterol intake = 260 mgs
It contains no fat . The body cannot derive energy from cholestrol.
* Daily starch intake = 260 grams
starch gives out 4 calories of energy from 1 gram
therefore the calorie obtained from 260 grams of starch = 240 x 4 = 960 kcal
* Daily simple sugar intake = 140 grams
sugar gives out 4 calories from 1 gram
therefore the calorie obtained from the 140 grams of sugar = 140 x 4 = 560 kcal
* Daily fiber intake = 9 grams
Daily fiber intake of 1 gram might be considered as beeing providing with 4 calories of energy
therefore 9 grams of fiber provides certain amount of energy. that is = 9 x 4 = 36 kcal
* Daily protein intake = 70 grams
1 gram also provides 4 calories of energy
therefore the 70 grams of the potien gives out energy as much as= 4 x 70 = 280 kcal
* Daily sodium intake = 3500 mgs
salt does not produce the calories.
so lets calculate the total amount of calories: 360+ 360+ 960 + 560+ 36+ 280 = 2560 kcal
