The human body stores approximately 7,700 calories in one kilogram of body fat. This means that 1000 calories is a small fraction of a kilogram of fat, emphasizing that a calorie surplus or deficit over time, not a single meal, determines weight change.

According to the National Institutes of Health, calories are the units of energy our body gets from food, powering everything from breathing to running. This fundamental measurement of energy is why it is important to understand calories, as it provides the basis for making informed decisions about diet, weight management, and overall health.

According to the World Health Organization, overweight and obesity affect 2.5 billion adults globally. This statistic underscores why it is important to pay attention to calories in food, as balancing energy intake and expenditure is fundamental to maintaining a healthy weight and preventing numerous associated health problems.

Over 50% of the energy expended each day powers the body's basic metabolic processes, showcasing how crucial efficient physiological function is to life. This comprehensive guide explains what is the physiology of the diet, exploring how our food intake impacts the complex, interconnected systems of the human body.

Approximately 70% of the calories we consume daily are used for basic bodily functions like breathing and circulation, proving that food has energy in a very real, tangible way. This article delves into how our bodies extract and use this energy to power our lives.

The human body is remarkably efficient, but it does not prioritize protein for immediate fuel. The question, is protein an immediate source of energy?, reveals a common misconception about macronutrient metabolism and the body's preferred fuel sources.

The hypothalamus is a small, almond-sized structure deep within the brain that serves as the body’s central control center for many essential functions, including energy balance. In fact, this vital area is a master regulator, integrating hormonal signals to influence appetite, energy expenditure, and overall metabolic health.

According to the World Health Organization, in 2022, 2.5 billion adults were overweight, largely due to an energy imbalance. Understanding why we need energy balance is crucial because it is the fundamental principle governing weight, metabolic health, and long-term well-being. This equilibrium is not just about weight, but about fueling your body for optimal function, from cellular processes to physical performance.

Approximately 60-70% of a person's daily energy expenditure is used for basic bodily functions while at rest. This critical process, alongside the energy burned from digestion and physical movement, constitutes the total calories your body expends daily.

The body does not store fat instantaneously, but rather over a period of several hours following a meal as part of a complex metabolic process. Understanding how long it takes for fat to be stored involves knowing how your body digests and processes different types of foods.
