What occurs when there is a caloric deficit?

When there is a caloric deficit, it means that the body is consuming fewer calories than it requires to maintain its current weight. This situation prompts the body to use stored energy, typically in the form of fat, to meet its energy demands. As a result, the body loses weight over time because it is utilizing these fat reserves to make up for the shortfall in caloric intake. This physiological response is a fundamental principle in weight management and is important for understanding how diet and exercise can influence body composition.
