Calculate your calorie intake based on the weight you want to lose

Use this calorie calculator for weight loss to estimate how many calories you need to cut down on in order to achieve a given weight loss target, depending on whether or not you want to change your physical exercise level as well. The weight loss calculator will also suggest mixed regime of caloric reduction and more intensive exercise.

The science behind the weight loss calculator
This calculator which computes the difference between your caloric intake and energy expenditure in order to estimate the number of calories you need to consume daily in order to achieve your body weight target. Calculation of Total Daily Energy Expenditure (a.k.a. Total Energy Expenditure) and Body Fat Percentage is done using the formulas described in our respective dedicated calculators. You can find the formulas and references for them under each tool.

The computation of the proportion of energy intake which needs to be cut down is performed in several steps. First, we compute the proportion of fat mass (FM) and fat free mass (FFM) which you are expected to lose since variability in this proportion can result in large differences in required caloric intake restriction. It is known that persons with a larger percentage of body fat usually lose a larger proportion of fat versus fat-free mass, which requires a larger energy deficit to achieve.
