Help on Question

Published

I need help on the following question can anyone figure out what the answer is?

Assume that for breakfast you ate a sausage bisquit from a fast food restaurant that contained 30 grams of carbohydrates, 28 grams of fat, 10 grams of protein. What was the total kcal for these nutrients for this meal? What percent of energy was derived from protein? What percent of energy was derived from fat?

Can anyone help me!!!!

Thanks

i assume you'd use the 9 cal for fat, 4 cal for pro, and 4 cal for carb...multiply then get the percentage of each.

Yep, you are correct.

I didn't understand where the numbers were coming from in the above posts, and I couldn't remember how to calculate this stuff, so I looked it up and thought I'd post what I found in case anyone else was confused.

The most common way to calculate calorie ratios is the '4-4-9 method'. Each gram of protein contains 4 calories, each gram of carbs contains 4 calories, and each gram of fat contains 9 calories. So we would multiply 30 x 4 for carb calories (120), 10 x 4 for protein calories (40), and 28 x 9 for fat calories (252). Total calories is 120 + 40 + 252, then you can divide each one by the total to get its percentage.

so the total is 412 cals, so 29% came from carbs,10% from protein, and 61% is from fat... I rounded these off....
