Common sense and conventional wisdom say that one should consume as many calories as needed for the body to maintain its normal function. So how many calories does your body need? Use the calculator on the left to find out your daily calorie needs. Leave the lifestyle sedentary if you work mainly in office. Otherwise select the appropriate lifestyle that describes you best; select light, moderate, high workout or athlete if you work out 1-3, 3-5, 5-7, or more times a week respectively. Computed Basal Metabolic Rate is the energy needed for your body to function without doing any work; Total Daily Energy Expenditure is computed by multiplying this number with the appropriate factor.
