Never look at the calorie amount already listed on a nutrition label because it gets estimated far too often. But calculate it on your own by knowing: 1 gram of proteins = 4 calories (or kilocalories or kcal depending on where you live) 1 gram of fats = 9 calories (or kilocalories or kcal depending on where you live) 1 gram of carbohydrates = 4 calories (or kilocalories or kcal depending on where you live) 1 gram of alcohol = 7 calories (or kilocalories or kcal depending on where you live) (it technically is a carbohydrate) 1 gram of fiber = 0 calories (or kilocalories or kcal depending on where you live) (yes it's a macronutrient, not a micronutrient since your body needs a lot of it, it's also technically a carbohydrate, and it's 0 calories because your body cannot digest it)
