Step 3: Plug Values into the Formula
With the total calories and total weight in grams, simply divide the two:
Calories Per Gram = Total Calories / Total Weight (in grams)
For example, if a 100-gram serving of almond butter contains 588 calories, the calculation would be:
Calories Per Gram = 588 calories / 100 grams = 5.88 calories/gram
Types of Foods and Their Caloric Content
To further illustrate how to calculate calories per gram, let’s look at a few common food categories and how their caloric content varies.
Fruits
Fruits generally have a low caloric density, which means a small number of calories packed in a larger volume. For example, a medium apple weighs about 182 grams and contains roughly 95 calories.
Now, let’s calculate the calories per gram:
Calories Per Gram = 95 calories / 182 grams ≈ 0.52 calories/gram
Vegetables
Vegetables, similar to fruits, tend to be low in calories. A medium-sized carrot weighs around 61 grams and contains about 25 calories.
Calculating the calories per gram leads to:
Calories Per Gram = 25 calories / 61 grams ≈ 0.41 calories/gram
Grains
Grains can vary more in calories. For instance, one cup (about 158 grams) of cooked brown rice contains around 215 calories.
Calculating this gives:
Calories Per Gram = 215 calories / 158 grams ≈ 1.36 calories/gram
Meat and Dairy
These food categories are generally richer in calories. For example, a 100-gram serving of cooked chicken breast has roughly 165 calories.
Calculating the calories per gram:
Calories Per Gram = 165 calories / 100 grams = 1.65 calories/gram
Fats and Oils
Fats are the most calorie-dense macronutrient. A tablespoon of olive oil (approximately 14 grams) contains around 120 calories.
Calculating this would yield:
Calories Per Gram = 120 calories / 14 grams ≈ 8.57 calories/gram
