Energy balance

Energy balance is the relationship between the amount of energy consumed (through food and drink) and the amount of energy expended (through activities such as metabolism, physical activity, and growth). When the amount of energy consumed is equal to the amount of energy expended, it is called energy balance. However, when the amount of energy consumed is greater than the amount expended, it can lead to weight gain. Conversely, when the amount of energy expended is greater than the amount consumed, it can lead to weight loss.

Metabolism

Metabolism is the process by which the body converts food into energy. It involves a series of chemical reactions that occur in various organs and tissues in the body. The amount of energy expended by the body at rest is known as basal metabolic rate (BMR). It is influenced by various factors such as age, gender, body size, and body composition. Physical activity and the thermic effect of food are also key contributors to energy expenditure and metabolism.

Maintaining energy balance

In order to maintain energy balance, it is important to consider both the quality and quantity of food consumed, as well as the level of physical activity.

• Diets that are high in fat and sugar can lead to weight gain and an imbalance in energy.
• Diets that are high in fiber and protein can help to increase satiety and maintain energy balance.
• Regular physical activity can also help to increase energy expenditure and maintain a healthy weight.
