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.
Every gram of carbohydrate has 4 calories, so 20 grams of carbohydrates would be 80 calories. But you also have to take into account the amount of protein and fat grams in the food, as well. Protein has the same amount of calories as carbohydrates (4 calories per gram) and fat has 9 calories per gram.
Each gram of fat has 9 calories. So there would be around 4 grams of fat.
Dietary protein has a metabolic energy density of roughly 4.9 kcal/gram, so 8 grams of protein is roughly 39 calories.
How many calories are in a food which has 10 grams of protein, 4 grams of fat, and 20 grams of carbohydrate
Every gram of carbohydrates contains four calories. If your nutrition label says that the food you are eating contains 5 g of carbohydrates, then you are eating 20 calories from carbohydrates. So that means that there are 25 grams of carbs in 100 calories
calories are energy. food contains calories, so when you eat food, the calories within the food power your body.
25*9=225 Answer: 225kcal
Food a contains 150 calories in three forth serving. That makes 200 calories per serving. Food B contains 250 calories per two third serving. That makes 375 calories per serving. So food A has got less calories per unit serving as compared to food B.
