Question

Now consider an athlete who eats twice as much CHO (in grams) as the student an has a much higher energy intake (6000 kcalories a day). What percentage does CHO contribute to this person's daily intake? How does CHO intake compare to the DV of 300 grams? To the 45 to 65 % recommendations. In an attempt to lose weight, a person adopts a diet that provides 150 grams of CHO per day and limits energy intake to 1000 kcalories. What percentage does CHO contribute to this person's daily intake? How does this CHO intake compare to the DV of 300 grams? To the 45 to 65 % recommendation.

Explanation / Answer

1.firstly calculate the carbohydrates intake ( for example take 70% of energy intake and 2000 calories a day).

problem: 0.7 x 2000 kcal/day = 1400 kcal

-> 1400 kcal from carbohydrate = 4 kcal/gm

->4 kcal/gm = 350 gm carbohydrates.

*) now the main calculation.

-> 350gm carbohydrates x2( for twice intake) = 700 gm carbohydrates /day.

> now convert into kcal.(i.e) 700 g carbohydrates x 4 kcal/gm.

->(i.e) = 2800kcal from carbohydrates

-> now for 6000 kcal / day calculate 2800 kcal from carbohydrates /6000kcal /day = 0.47.

->i.e 0.47 x100= 47% from carbohydrates

->yes this carbohydrate intake is higher than daily value and meets the 45 to 65% recommendation.
