About 10-35% of your daily caloric intake should come from protein, according to dietary guidelines. This macronutrient plays a vital role in muscle repair, immune function, and the production of enzymes and hormones. Adequate protein intake is essential for various bodily processes and helps maintain a sense of fullness, which can assist in weight control. Individual needs may vary based on factors like age, activity level, and fitness goals, making it important to tailor protein consumption accordingly.
