How Many Calories Do I Need?
People ask us this question quite often, “How many calories do I need?� It is a good question worth exploring. The number of calories you need depends on how much energy your body uses.
People have different basal metabolic rates (level of energy required to support involuntary body processes, such as breathing, heart beat, and so forth), levels of physical activity, body sizes and compositions (proportion of fat, muscle, water), health status, and growth stages.
When the food you eat routinely provides more calories than your body needs, the excess calories are converted to fat – a storage form of energy – and you gain weight. [source: eating.org]
