Calories Per Gram

Remember that there is:

4 Calories per gram of Protein 

4 Calories per gram of Carbohydrates 

7 Calories per gram of Alcohol

9 Calories per gram of Fat

So if you are eating something that has 19 grams of protein, 11 grams of carbohydrates and 8 grams of fat. That comes up to 192 calories.
