Fat burning refers to the process by which the body uses stored fat as a source of energy. This occurs when the body is in a calorie deficit, meaning it consumes fewer calories than it expends. During this state, the body breaks down fat cells to release fatty acids, which are then converted into energy. Several factors influence fat burning, including diet, exercise, and metabolism. Engaging in regular physical activity, particularly aerobic exercise and strength training, can enhance the body's ability to burn fat. Additionally, a balanced diet rich in whole foods can support this process by providing essential nutrients while managing calorie intake.
