Your indicated weight goal: 62 kgs
Resting metabolic rate requires 1612 calories per day (basal energy expenditure). This is the amount of calories required to maintain the body's normal metabolic activity ( respiration, maintenance of body temperature etc. ) Important DetailsMaximum calories/day in order to lose weight: 1595.6(In order to lose 1 to 1.5 pounds each week or (4-6 pounds/month) you must subtract 500 calories from your estimated daily caloric needs (2095.6).
