Weight loss occurs when you burn more calories than you consume, which is also known as being in a caloric deficit. Your metabolism is also directly to your metabolism. Metabolism is the process by which your body converts what you eat and drink into energy. During this complex process, calories in food and beverages are combined with oxygen to release the energy your body needs to function.
Even when you're at rest, your body needs energy for all its "hidden" functions, such as breathing, circulating blood, adjusting hormone levels, and growing and repairing cells. The number of calories your body uses to carry out these basic functions is known as your basal metabolic rate — what you might call metabolism.
Several factors determine your individual basal metabolism, including:

Several factors determine your individual basal metabolism, including:
- Your body size and composition. People who are larger or have more muscle burn more calories, even at rest.
- Your sex. Men usually have less body fat and more muscle than do women of the same age and weight, which means men burn more calories.
- Your age. As you get older, the amount of muscle tends to decrease and fat accounts for more of your weight, slowing down calorie burning.
