While he is famously known for his love of Skittles during games, sources indicate Marshawn Lynch's diet is primarily focused on functional fuel. The former NFL running back combines his iconic candy tradition with a disciplined, whole-food approach to nutrition, often leaning toward plant-based meals.

According to research, protein provides 4 calories per gram, the same as carbohydrates, but is not the body's preferred or most efficient source of energy. While it primarily functions as a building block for tissues, the body can and will use protein as a source of fuel under specific circumstances.

Approximately 80-85% of a healthy adult's energy reserves are stored as fat. The human body has developed a sophisticated system for storing the food we consume, transforming and depositing it in specific locations to ensure a continuous and stable supply of energy. So, where do we store food in the body?

According to nutritional science, one gram of fat provides 9 calories of energy, more than double the energy from one gram of protein or carbohydrate. This fact highlights the differing roles and energy densities of the three primary macronutrients that can provide energy for the human body.

Every human cell relies on a molecule called adenosine triphosphate (ATP) for energy, which is primarily created from the food we consume. The three fundamental sources of energy for the body are the macronutrients: carbohydrates, fats, and proteins.

According to the National Institutes of Health, glucose is your body's main source of energy, derived from the carbohydrates you consume. It is the universal fuel for the fetus and the primary metabolic fuel for most mammals, including humans.

For every gram you consume, carbohydrates provide 4 calories of energy. This critical macronutrient is the body's preferred fuel source, and understanding exactly how much energy do you get from carbohydrates is key to managing your diet and energy levels.

Every human body runs on energy derived from three main macronutrients: carbohydrates, fats, and proteins. Understanding precisely **what macros are used for energy** is fundamental to managing your diet for optimal physical performance, weight, and overall health.

While one gram of fat provides more than twice the calories of one gram of carbohydrate, the answer to which nutrient gives the body more energy is complex. The body's utilization of these macronutrients for fuel depends on various factors, including the intensity of the activity and overall dietary composition.

Scientific evidence shows that glucose, derived from carbohydrates, is the human brain's preferred and primary source of fuel. This makes sense when you understand why carbohydrates are better for quick energy than other macronutrients like fat or protein.
