Assuming 4 kcal/g for carb and protein and 9 kcal/g for fats, the total would be
(15 x 9) + (25 x 4) + (20 x 4) = 315 kcal.
5.2*9, so about 47

A food source with five grams of protein, ten grams of fat, and twenty grams of carbohydrates contains 190 calories. To find this, you need to know how many calories are in a gram of protein, fat, and carbohydrates. There are four calories in one gram of protein and one gram of carbohydrates. There are nine calories in one gram of fat. Then multiply five (the number of grams of protein) by four (the number of calories in one gram of protein), ten (the number of grams of fat) by nine (the number of calories in one gram of fat), and twenty (the number of grams of carbohydrates) by four (the number of calories in one gram of carbohydrates). Add those numbers up and you will know how many calories are in the food.
If you are talking about getting 100 calories from pure protein, there are 25 grams of protein. However, a lot of foods have a mixture of protein, carbohydrate, and fat. So this isn't necessarily the case with all foods. Take a look at the nutrition fact label to see how many grams of protein/fat/carbohydrate are in each serving. 1g protein=4 calories 1g carbohydrate=4 calories 1g alcohol=7 calories 1g fat=9 calories
