Tag: Fat vs starch

Nutritional science shows that fat contains approximately 9 calories per gram, more than double the 4 calories found in starch. This vast difference in caloric density highlights why fat serves as a highly efficient, long-term energy storage solution, while starch primarily functions as a source of quick energy.

A single gram of fat provides about 9 calories of energy, which is more than double the 4 calories per gram offered by starch. This significant disparity in energy density is the fundamental reason why fat stores more energy than starch, and it all comes down to the underlying chemical structures of these macronutrients.
