Calorie density of foods

Calorie density is the number of calories in a gram of food (kcal/g). Foods high in water and fiber sit at the low end — you can eat a lot of them for very few calories. Fatty, dry, or sugary foods concentrate energy at the high end. Every food page shows calories per gram, per 100 g, and per common portion.

The four tiers

Tier	Density	What it means
Very low	under 0.6 kcal/g	Mostly water and fiber. You can eat a large volume of these foods for very few calories.
Low	0.6 – 1.5 kcal/g	Filling foods that keep portions generous while staying easy on your calorie budget.
Moderate	1.5 – 4 kcal/g	Balanced foods. Reasonable in normal portions, but the calories add up faster than you might expect.
High	over 4 kcal/g	Calorie-packed. Small weights carry a lot of energy, so portion size matters a lot here.
