The Burniva Weight Loss Calculator uses your Body Mass Index (BMI) value to establish your ideal weight range. BMI is a calculation that uses your height and weight to estimate how much body fat you have.
Ideally your BMI should be in the 18.5 to 25 range that is considered normal. If your BMI value which exceeds 25, then according to this index, you are over-weight and it is recommended that you embark on a weight-loss programme designed to reach your ideal weight target.
An effective weight-loss programnme requires the creation a calorific deficit. In essence you need to consume less calories than would normally be required for a person of your age, sex, and activity level through a controlled diet, or burn more calories than you are consuming through increased excercise. A combination of the two approaches i.e. controlling your food intake, and excercise, would not just accelerate your weight-loss programme, but also lead to the change in lifestyle required to stay within your ideal weight.
So, how big should this calorific defict be to hit your target. We recommend a gradual approach to weight-loss, creating a small, daily, calorific deficit. Based on your age, sex, and activity level, The Burniva Weight Loss Calculator estimates your Basic Metabolic Rate (BMR). The BMR is a measure of your daily calorific requirements at rest i.e. if you sit on your couch all day watching T.V. Once you specify your ideal weight target, and the time-span within which you would like to achieve your goal, the Burniva Weight Loss Calculator estimates the daily calorific deficit necessary to reach your goals. You will discover that losing weight within a reasonable time-span, is not as hard as you probably though if you set yourself small, long-term goals.
