What does the concept of salmon being nutrient-dense imply regarding its energy concentration?

Density implies concentration of energy

The confusion surrounding salmon consumption and weight gain often arises from misinterpreting the term 'nutrient-dense.' Salmon is indeed incredibly nutrient-dense, meaning it packs essential vitamins, minerals, protein, and fats into a relatively small physical package. However, this density also implies concentration of energy. Unlike foods such as celery, which are volume-dense (large mass, low calories), salmon's concentration of fats and protein means it carries a significant energy load in a small serving. For weight management, this energy concentration requires careful tracking, even though the high protein content assists in promoting fullness.
