Question

Calculate this problem:

     Your friend eats 1800 calories per day.  

     If he limits his calories from fat to 30% per day.  How many calories

     would be from fat?

     

     How many grams of fat would this be per day?

     

     How many calories from saturated fat would this be per day?

     

     How many grams of saturated fat would this be per day?

Answer 1

Since 30% of total calories are to come from fat.

Therefore, calories from fat = 30% of total calories = 30*1800/100 = 540 calories

Now, we know 1 g of fat contains 9 calories.

Therefore, 540 calories will be there in 540/9 = 60 g of fat. Hence 60 g of fat per day.

Now, if all the fat that your friend eats is saturated fat then it will be 540 calories per day from saturated fat, and also it will be 60 g of saturated fat per day.

But if your friend follows the recommeded limits which is no more than 7% of the daily calories should come from saturated fat.

Then 7% of total calories = 7*1800/100 = 126 calories from saturated fat per day

Since like normal fat, saturated fat also contains 9 calories per g.

Therefore, grams of staurated fat can be calculated as 126/9 = 14 g of saturated fat per day.
