Calories are just a measure of energy-measuring calories in food and calories released in the human body. According to the professional statement, 1 calorie can make 1 gram of water rise 1 degree Celsius. Heat is not a nutrient, but many nutrients give us heat. Protein, carbohydrates and fats are combined into various foods containing calories.

1g protein contains 4 kilocalories. 1 g carbohydrate contains 4 kilocalories. 1 g fat contains 9 kilocalories. 1 g alcohol contains 7 kilocalories.

Extended data:

We often associate calories with food, but in fact they apply to any substance that contains energy. Simply put, 1 calorie of energy or heat can raise the temperature of 1 gram of water by 1 degree Celsius at one atmospheric pressure. 1 calorie is approximately equal to 4. 186 joules (joules are commonly used units of energy in physics).

Daily calorie requirement of adults = basic calorie required for basic metabolism of human body+calorie required for physical activity+calorie required for digestion of food.

Heat required for digesting food = 10%x (minimum heat required for basic metabolism of human body+heat required for physical activity) Daily heat required for adults = 1. 1x (minimum heat required for basic metabolism of human body+heat required for physical activity).
