What is the kcalorie value of a meal supplying 110g of carbs, 25g of protein, 20g of fat, and 5g of alcohol?

To find the kcalorie value of a meal, you need to know the energy content of each macronutrient (carbohydrates, proteins, fats, and alcohol) and then calculate the total energy by multiplying the grams of each nutrient by its energy content.

The energy content of each macronutrient is as follows:
- Carbohydrates: 1 gram = 4 kilocalories (kcal)
- Proteins: 1 gram = 4 kcal
- Fats: 1 gram = 9 kcal
- Alcohol: 1 gram = 7 kcal

Given the amounts of each nutrient in the meal:
- Carbohydrates: 110g
- Proteins: 25g
- Fats: 20g
- Alcohol: 5g

Now, let's calculate the energy (kcal) from each macronutrient:

Carbohydrates: 110g x 4 kcal/g = 440 kcal
Proteins: 25g x 4 kcal/g = 100 kcal
Fats: 20g x 9 kcal/g = 180 kcal
Alcohol: 5g x 7 kcal/g = 35 kcal

To get the total kcalorie value of the meal, sum up the energy from each macronutrient:

Total kcalories = Carbohydrates + Proteins + Fats + Alcohol
= 440 kcal + 100 kcal + 180 kcal + 35 kcal
= 755 kcal

Therefore, the meal supplies 755 kcal (kilocalories) in total.
