Tag: Energy substrates

The human body requires a constant supply of energy to power all its activities, from basic cellular processes to intense physical exercise. A single gram of fat, for instance, provides more than double the energy of a gram of carbohydrate or protein, highlighting the differing energy density of the primary fuels. Understanding what are the three main substrates for the body is crucial for comprehending human metabolism and nutrition.

While protein is the primary macronutrient for muscle tissue repair, fat plays a vital, supportive role in the recovery process. During the post-exercise period, healthy fats assist in managing inflammation, regulating hormones, and replenishing energy stores, which is often a more complex process than many people realize.
