How many calories does your body need to maintain its current weight? Or rather, if we were to take your current weight level and assume that you're consuming enough Calories to maintain it, how many Calories is that per day?
Math is a wonderful thing and yes, we can use it to work out approximately how many Calories you're eating every day! Our tool below uses the math developed by M.D. Mifflin, S.T. St. Jeor, L.A. Hill, B.J. Scott, S.A. Daugherty and Y.O. Koh in their 1990 paper "A new predictive equation for resting energy expenditure in healthy individuals" to estimate your basal metabolic rate, or rather, the number of Calories your body would consume when it's "resting", which we then mashed with the old Harris-Benedict approximations for taking your daily level of physical activity into account.
All you need to do is to enter your age, gender, weight and your approximate level of daily physical activity into our tool below. Unless you're a true athlete, with lots of lean muscle mass that burns even more Calories, or perhaps have a thyroid condition that directly affects your metabolic rate, you can expect the results to be pretty close to the actual ballpark in which your body burns Calories to maintain your current weight!
Best of all, if you're getting set to do something about your weight or fitness level, you now have some idea of how many Calories you're really consuming every day!
And really, that might be the most surprising result you'll find out from our tool!
