If a person consumes 300 grams of carbohydrates in a day, what percentage of their total caloric intake (assuming 1 gram of carbohydrate = 4 calories) does this represent if their total intake is 2400 calories? (2020)
Step 1: Determine how many calories are in 300 grams of carbohydrates. Use the conversion that 1 gram of carbohydrate equals 4 calories.
Step 2: Calculate the total calories from carbohydrates: 300 grams * 4 calories/gram = 1200 calories.
Step 3: Find the total caloric intake, which is given as 2400 calories.
Step 4: Calculate the percentage of total caloric intake that comes from carbohydrates. Use the formula: (calories from carbohydrates / total caloric intake) * 100.
Step 5: Plug in the numbers: (1200 calories / 2400 calories) * 100.
Step 6: Simplify the calculation: 1200 divided by 2400 equals 0.5, and then multiply by 100 to get 50%.
Caloric Calculation – Understanding how to convert grams of macronutrients into calories and calculate their percentage of total caloric intake.
Percentage Calculation – Applying the formula for percentage to determine the proportion of calories from carbohydrates relative to total caloric intake.
