Metabolism refers to the body’s processes that convert food into energy and other vital components for cellular function. Nutritional physiology explores how different nutrients—carbohydrates, proteins, and fats—are broken down and utilized by the body. Research in this field aims to understand the influence of various macronutrients and micronutrients on metabolic pathways and overall health. Metabolic studies help in identifying the effects of nutrient deficiencies or excesses, which can lead to conditions such as obesity, diabetes, or metabolic syndrome. Additionally, understanding metabolic variations among individuals can help in designing personalized nutrition plans that enhance health outcomes and improve athletic performance or weight management strategies.
