Metabolic Rate –
Your body’s metabolic rate (or total energy expenditure) can be divided into three components, which are:
Basal Metabolic Rate (BMR) – the amount of kilojoules (kJ) burned at rest. BMR includes the energy the body uses to keep all its systems functioning correctly. It accounts for the largest amount of energy-expended daily.
Physical Activity – Physical activity is by far the most variable of the factors that determine how many calories you burn each day.
Food Processing – is the energy you use to eat, digest and metabolise food. Digesting, absorbing, transporting and storing the food you also consume takes calories.

Several factors determine your individual basal metabolic rate:
Your body size and composition – The bodies of 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 women of the same age and weight, burning 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.

Metabolism and Weight – Many people blame their metabolism for weight gain. But because metabolism is a natural process, your body has many mechanisms that regulate it to meet your individual needs. Only in rare cases is excessive weight gain from a medical problem that slows metabolism, such as having an underactive thyroid gland (hypothyroidism). Unfortunately, weight gain is complicated. It is likely a combination of genetic makeup, hormonal controls, diet, and your lifestyle, including sleep, physical activity, and stress. All of these factors result in an imbalance in the energy equation. You gain weight when you eat more calories than you burn. To lose weight, you need to create an energy deficit by eating fewer calories or increasing the number of calories you burn through physical activity.
