Fat
Fat is a macronutrient that provides a concentrated source of energy at 9 calories per gram.
Fat is energy-dense, so small portions can contain a large number of calories. It does not create strong immediate signals of fullness for many people. This makes it easy to consume more than intended without noticing. Being aware of fat intake helps keep total calories under control.
