A good weight loss strategy should include dietary, behavioral and psychological changes to your daily life and habits.
The amount of fat you store is determined by the amount of food you ingest and your metabolism (the way your body uses the energy in the food). The energy in food can be measured in calories and the amount required to perform basic life-sustaining functions is considered your base metabolic rate (BMR).

Metabolic rate is affected by a variety of genetic and environmental factors. It can be increased with exercise such as cardio and resistance training.
