What is energy density?
Energy density of food is represented in how many calories (energy) are in one gram of food.
The lower the energy density the larger portions of food you can consume with fewer calories.
Picture below is a classic example of the power of energy density.
The same amount of calorie but different quantities of food.
Formula for energy density.
As mentioned above, we are trying to calculate energy per gram. So, in order to find out the energy density of your food or your recipe, you should:
Energy Density = Total Calories/Total Grams
Energy density categories.
There is no official categorization of foods based on energy density.
Usually, people refer to low energy foods that are lower than 2.5 calories per gram
Medium energy density is from 3 to 6 calories per gram
High energy density foods are defined as from 6 to 9 calories per gram.
What does energy density tell us?
Energy density plays a big part when in our data driven nutrition. It tells us on the spectrum whether foods should be used fo weight loss, maintenance, or bulking.
