Question

Note the following values:

Protein is 4 calories per gram.
Carbohydrates/sugar is 4 calories per gram.
Fat is 9 calories per gram.
It is recommended for most adults that carbohydrates make up 45–65% of their diet, proteins make up 10-35% of their diet, and fats make up 20–30% of their diet. Does Deb’s diet meet these recommendations? Support your statement with calculations.

Answer 1

did you figure it out

Answer 2

no i am unsure how to go about figuring it out

Answer 3

how did you come up with those numbers?

Answer 4

thank you, i have a really hard time in math and biology so i am lost a lot when doing work in those subjects i still am lost thank you for your help/

Answer 5

i think u multiply or devide

Answer 6

The percentages are based on percent *calories*. So carbohydrates need to be 45-65% of total calories; protein needs to be 10-35% of calories; fats need to be 20-30% of calories.

It also gives you:
Protein is 4 calories per gram.
Carbohydrates/sugar is 4 calories per gram.
Fat is 9 calories per gram.

So take Deb's diet:
1. multiply grams protein by 4 to get calories from protein
2. multiply grams carbohydrates by 4 to get calories from carbs
3. multiply grams fat by 9 to get calories from fat
4. add up the totals from steps 1-3 to get her total calorie intake
5. divide calories protein/total calories and multiply by 100% to get % protein. repeat with carbs and fat.
6. check to see if all three categories are within the guidelines.
