Concentrated Stored Energy Source in Diet
In one's diet, the most concentrated stored energy source is fats. Fats contain 9 calories per gram, more than twice the energy of carbohydrates and proteins, which both contain 4 calories per gram. Fats are a vital component of our diet and serve as a long-term energy reserve. They provide insulation, protect organs, and help transport fat-soluble vitamins in the body.
Carbohydrates and proteins are also sources of energy, but fats provide the most concentrated form of energy due to their higher caloric content. Carbohydrates are the body's primary source of quick energy, while proteins play crucial roles in growth, repair, and maintenance of body tissues.
