Some of the energy in macronutrients is lost through the digestive process. True or False?

The statement that some of the energy in macronutrients is lost through the digestive process is true. During digestion, the body breaks down food into smaller particles to absorb the nutrients necessary for energy and bodily functions. However, this process is not 100% efficient. Some energy is lost as heat due to metabolic processes and the energy required for digestion, absorption, and processing of food, known as the thermic effect of food.

Additionally, not all macronutrients are fully digested and absorbed; some may pass through the digestive system without being utilized, contributing to energy loss. This natural inefficiency in the digestive process is a critical factor in understanding energy balance and metabolism, particularly for those studying nutrition, exercise physiology, or personal training.
