✅ Proteins
🌹 Proteins are one of the three energy-providing macronutrients, supplying 4 kcal/g of energy.
🌹 Their primary function is growth, tissue repair, enzyme production, and immune support, but they can also be used for energy when carbohydrate intake is insufficient.
🌹 During prolonged fasting or starvation, the body breaks down muscle protein to produce glucose through gluconeogenesis.
🌹 Protein is obtained from foods such as meat, fish, eggs, dairy products, legumes, and soy products.
🌹 Adequate protein intake helps maintain lean body mass and promotes wound healing.
🌹 Excessive protein used for energy is inefficient because its primary role is tissue maintenance.
🌹 A balanced diet includes adequate protein along with carbohydrates and fats.
🌹 Proteins are an energy-providing macronutrient, supplying 4 kcal/g.
✅ Fats
🌹 Fats are the most concentrated energy source, providing 9 kcal/g.
🌹 They serve as the body's primary long-term energy reserve and are stored in adipose tissue.
🌹 Fats also aid in the absorption of the fat-soluble vitamins A, D, E, and K.
🌹 Essential fatty acids are necessary for cell membrane integrity, hormone production, and normal neurological function.
🌹 Healthy fat sources include nuts, seeds, avocados, olive oil, and fatty fish.
🌹 Consuming excessive saturated and trans fats increases the risk of cardiovascular disease.
🌹 Moderate intake of healthy fats is an important part of a balanced diet.
🌹 Fats are the highest-energy macronutrient, supplying 9 kcal/g.
✅ Carbohydrates
🌹 Carbohydrates are the body's preferred and primary source of energy, providing 4 kcal/g.
🌹 Glucose derived from carbohydrates is the main fuel for the brain, red blood cells, and working muscles.
🌹 Complex carbohydrates, such as whole grains, legumes, fruits, and vegetables, provide sustained energy and dietary fiber.
🌹 Carbohydrates help spare protein from being used as an energy source.
🌹 Adequate carbohydrate intake supports normal metabolic function and physical activity.
🌹 Fiber, although not digested for energy, promotes healthy bowel function and cardiovascular health.
🌹 Choosing complex carbohydrates over refined sugars improves long-term health outcomes.
🌹 Carbohydrates are the body's primary energy source, supplying 4 kcal/g.
