However, women should not eat fewer than 1,200 calories a day, and men should not eat fewer than 1,800 calories a day, according to the American College of Sports Medicine. Subtract 500 calories, and she needs 1,409 calories to lose 1 pound a week. So, for example, a 41-year-old woman with a BMR of 1,388 calories who exercises three days a week needs 1,909 calories to maintain her weight: 1,388 x 1.375 = 1,909. If you're training for a marathon or have a physically demanding job, your activity factor is 1.9. ** If you're involved in sports and exercise six to seven days a week, your activity factor is 1.725. **If you exercise three to five days a week, your activity factor is 1.55. If you exercise one to three days a week, your activity factor is 1.375. If you do not exercise and have a desk job, your activity factor is 1.2. To calculate the calories you need to maintain your current weight, multiply your BMR by an activity factor. While the BMR provides the number of calories your body uses for basic functions, the other factors that affect calorie needs, including activity and the thermic effect of food, also account for part of your total calorie needs. To lose 1 pound a week, reduce your daily intake by 500 calories. For women: BMR = (9.99 x weight in kilograms) + (6.25 x height in centimeters) - (4.92 x age in years) - 161.Įating fewer calories than your body needs to function will result in weight loss.A number of formulas are used to estimate BMR.Think about it, in any given 24 hour period, most people spend most of their time time lying in bed asleep or sitting comfortably. Every little movement of any muscle is real exercise! BMR means We Burn Calories lying in Bed! ![]() Your liver alone burns about 15% of your daily requirement just by doing its basic job.Įvery person has muscle fibre which at some point will be active, so there is always a level of fitness regardless of body type. At least 60% of all energy used by everyone goes into basal metabolism. Truly, we burn most of our energy in “basal” mode. That’s what Basal Metabolic Rate (BMR) is! In fact, over time, this sort of activity burns the most calories. Utterly sedentary actions like simply reading these words is using energy. Just breathing in, and breathing out, is burning calories. Exercise is Good, but not Necessary, to burn kJsĪll this to say, your body burns kilojoules even without exercising. That person breathes more and has a higher BMR because a toned, fit body simply needs more energy.īesides muscle tone, body size, age, the ambient temperature, genes, hormone balance and other factors all affect the rate of energy burn at a basic level. Think about it: a person used to gym training and exercise simply breathes harder and stronger than a person with poor muscle tone. In reality, no two people can have the exact, identical BMRs. However, such a case of two people with the same metrics shows the limitations of any BMI-like formula. Our BMR Calculator applies the Harris Benedict formula to your height, weight, gender, and age, so two different people with the exact same weight, height, gender, and age will have identical results. Different People, Different BMR Calculator Results They stay functioning and using energy for as long as you are alive.īMR is your heart, lungs, liver and other essential organs just doing their thing. Think about what your body is doing when you are lying in bad, gazing up at the ceiling.Įven though you are not “doing anything”, your heart, liver, kidneys, brain and all the other organs are fully functional.
