An individual's caloric needs are influenced by several factors, including age, gender, weight, height, and level of physical activity. Basal metabolic rate (BMR), which denotes the calories burned at rest, plays a crucial role in determining overall caloric needs. Additionally, the type and intensity of physical activity significantly impact daily caloric expenditure. Individuals with higher activity levels require more calories to maintain body weight, whereas those with sedentary lifestyles may require fewer. Understanding these factors helps tailor dietary plans that align with individual health and fitness goals.
