Questions & Step-by-Step Solutions
If a person consumes 3000 calories a day and wants to ensure that 25% of their intake is from proteins, how many grams of protein should they consume (1 gram of protein = 4 calories)?
Step 1: Determine the total daily calorie intake, which is 3000 calories.
Step 2: Calculate 25% of the total calorie intake. This is done by multiplying 3000 by 0.25.
Step 3: Perform the calculation: 0.25 * 3000 = 750 calories. This is the amount of calories that should come from proteins.
Step 4: Know that 1 gram of protein equals 4 calories.
Step 5: To find out how many grams of protein this is, divide the calories from proteins (750) by the calories per gram of protein (4).
Step 6: Perform the calculation: 750 calories / 4 calories per gram = 187.5 grams of protein.
Step 7: Round 187.5 grams to the nearest whole number, which is 188 grams.
