The brain is the complex and intricate organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It controls and coordinates all bodily functions, including sensory perception, motor activity, thought, and emotion. The brain is made up of billions of interconnected neurons that communicate with each other through electrical and chemical signals, forming neural networks that enable learning, memory, and cognitive processes. It is protected by the skull and nourished by the circulatory system, and its proper functioning is essential for maintaining health and survival.

A calorie is a unit of measurement that indicates the amount of energy provided by food and beverages. When food is consumed, the body converts the calories into energy to fuel various physiological processes, such as breathing, circulation, and physical activity. The number of calories in a food item depends on its macronutrient composition: carbohydrates and proteins provide approximately 4 calories per gram, while fats provide about 9 calories per gram. Monitoring calorie intake is important for maintaining a healthy weight, as consuming more calories than the body uses can lead to weight gain, while consuming fewer can result in weight loss.
