One gram of carbohydrates provides total= 4 calories.

2 grams of carbohydrates would provide= 4 x 2 = 8 calories.

One gram of protein provides total= 4 calories.

2 grams of protein would provide= 4 x 2 = 8 calories.

One gram of fat provides total= 9 calories.

2 grams of carbohydrates would provide= 9 x 2 = 18 calories.

Total calories from food that gives two grams each of fat, carbohydrate, and protein= 8 + 8 + 18 = 34 calories.
