Kalóriafogyasztás

Kalóriafogyasztás refers to the total number of calories a person consumes through food and beverages. Calories are units of energy, and the human body needs them to perform all its functions, from breathing and circulating blood to physical activity. The amount of calories an individual needs varies based on several factors, including age, sex, weight, height, activity level, and overall metabolic rate. Consuming more calories than the body expends leads to weight gain, while consuming fewer calories than expended results in weight loss. Maintaining a healthy weight typically involves balancing calorie intake with calorie expenditure. Different types of food provide varying amounts of calories and nutrients. Macronutrients like carbohydrates, proteins, and fats are the primary sources of calories. Understanding one's personal calorie needs is a fundamental aspect of nutrition and weight management. This concept is central to dietary planning and is often discussed in relation to health and fitness goals.
