But, these are the highlights:<\/span><\/p><h3>Background of BMR formulas<\/h3><p><span style=\"font-weight: 400;\">The earliest attempts to measure BMR stretch back into the 1800s, and the earliest formulas developed to estimate BMR from factors like height, weight, age, and sex date back to the 1910s. Today\u2019s best BMR formulas are based on meta-analytic research, pooling the results of multiple studies with hundreds, thousands, or even tens of thousands of subjects. The BMR calculator above builds on the two best \u201coff-the-shelf\u201d BMR formulas developed from this type of meta-analytic research: the <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/1957828\/\">Cunningham equation<\/a> (sometimes erroneously referred to as the Katch-McArdle equation), and the <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/16277825\/\">Oxford\/Henry equations<\/a>.<\/span><\/p><p><span style=\"font-weight: 400;\">You can <a href=\"https:\/\/macrofactor.com\/best-bmr-equations\/\">learn more about the background of BMR formulas here<\/a>.<br \/><\/span><\/p><h3>Determinants of BMR, and the accuracy of BMR calculators<\/h3><p><span style=\"font-weight: 400;\">While formulas to estimate BMR have improved over the years, they still <\/span><i><span style=\"font-weight: 400;\">at best<\/span><\/i><span style=\"font-weight: 400;\"> only provide a rough approximation of your BMR. That\u2019s because your <a href=\"https:\/\/macrofactor.com\/determines-basal-metabolic-rate\/\">BMR is <\/a><\/span><a href=\"https:\/\/macrofactor.com\/determines-basal-metabolic-rate\/\"><i><span style=\"font-weight: 400;\">primarily<\/span><\/i><\/a><span style=\"font-weight: 400;\"><a href=\"https:\/\/macrofactor.com\/determines-basal-metabolic-rate\/\"> determined by <\/a>the mass of your high-metabolic-rate organs: your brain, liver, kidneys, and heart. They account for less than 5% of your total body mass, while accounting for more than 50% of your total BMR. Easily observable factors like height, weight, age, sex, and body composition are <\/span><i><span style=\"font-weight: 400;\">associated<\/span><\/i><span style=\"font-weight: 400;\"> with the mass of your high-metabolic-rate organs, but those associations are typically fairly weak. So, the output of BMR calculators shouldn\u2019t be treated as gospel \u2013 they\u2019re only intended to provide you with a <\/span><a href=\"https:\/\/macrofactor.com\/metabolism\/\"><span style=\"font-weight: 400;\">decent ballpark estimate<\/span><\/a><span style=\"font-weight: 400;\">. That\u2019s why the BMR calculator above provides you with both a point estimate of your BMR (the most likely value), and the range in which your <\/span><i><span style=\"font-weight: 400;\">actual<\/span><\/i><span style=\"font-weight: 400;\"> BMR is likely to fall (which accounts for the typical error of BMR calculators, and the typical variability of human BMRs).<\/span><\/p><p><span style=\"font-weight: 400;\">You can\u00a0<\/span><a href=\"https:\/\/macrofactor.com\/determines-basal-metabolic-rate\/\" target=\"_blank\" rel=\"noopener\">learn more about the determinants of BMR here<\/a><span style=\"font-weight: 400;\">.<br \/><\/span><\/p><h3>The impact of sex<\/h3><p><span style=\"font-weight: 400;\">Women\u00a0<\/span><a href=\"https:\/\/macrofactor.com\/aging-and-metabolism\/\" target=\"_blank\" rel=\"noopener\">tend to have lower BMRs<\/a><span style=\"font-weight: 400;\"> than men. When adjusted for factors like height, weight, and age, men generally have BMRs that are <\/span><i><span style=\"font-weight: 400;\">about<\/span><\/i><span style=\"font-weight: 400;\"> 150-200 Calories higher. However, that difference is <\/span><i><span style=\"font-weight: 400;\">primarily<\/span><\/i><span style=\"font-weight: 400;\"> due to differences in body composition: at a given height and weight, men tend to have a bit less body fat (which has a very small impact on BMR), and a bit more lean body mass (which has a larger impact on BMR). So, BMR calculators and formulas that account for body composition apply equally to both men and women \u2013 in other words, the relationship between total fat-free mass and BMR is the same for both sexes. An interesting upshot of that is that women actually have <\/span><i><span style=\"font-weight: 400;\">higher<\/span><\/i><span style=\"font-weight: 400;\"> BMRs per unit of fat-free mass, on average, because a greater proportion of their total fat-free mass is typically comprised of high-metabolic-rate organs. The same relationship applies within each sex as well (smaller women typically have a higher BMR per unit of fat-free mass than larger women, and smaller men typically have a higher BMR per unit of fat-free mass than larger men).<\/span><\/p><p><span style=\"font-weight: 400;\">You can\u00a0<\/span><a href=\"https:\/\/macrofactor.com\/sex-basal-metabolic-rate\/\" target=\"_blank\" rel=\"noopener\">learn more about the impact of sex on BMR here<\/a><span style=\"font-weight: 400;\">.<br \/><\/span><\/p><h3>The impact of age<\/h3><p><span style=\"font-weight: 400;\">BMR\u00a0<\/span><a href=\"https:\/\/macrofactor.com\/aging-and-metabolism\/\" target=\"_blank\" rel=\"noopener\">tends to decrease as we age<\/a><span style=\"font-weight: 400;\"> for a couple of reasons. First, most people lose muscle mass as they age. Second, tissue-specific metabolic rates decrease with age. In both cases, these effects occur very gradually at first, such that aging has very little impact on BMR from the start of adulthood until <\/span><i><span style=\"font-weight: 400;\">about<\/span><\/i><span style=\"font-weight: 400;\"> 60 years old. Past age 60, age-related declines in BMR begin to accelerate.<\/span><\/p><p><span style=\"font-weight: 400;\">You can\u00a0<\/span><a href=\"https:\/\/macrofactor.com\/aging-and-metabolism\/\" target=\"_blank\" rel=\"noopener\">learn more about the impact of age on BMR here<\/a><span style=\"font-weight: 400;\">.<br \/><\/span><\/p><h3>The impact of athletic status<\/h3><p><a href=\"https:\/\/macrofactor.com\/athlete-bmr\/\" target=\"_blank\" rel=\"noopener\">Athletes tend to have higher BMRs than non-athletes<\/a><span style=\"font-weight: 400;\">, but not for the reasons most people expect. It\u2019s commonly believed that athletes have higher BMRs because they tend to be leaner and have more muscle mass than non-athletes. While those body composition differences <\/span><i><span style=\"font-weight: 400;\">do<\/span><\/i><span style=\"font-weight: 400;\"> have an effect, research finds that athletes still have higher BMRs than non-athletes even when adjusting for those differences in body composition. Instead, athletes <\/span><i><span style=\"font-weight: 400;\">primarily<\/span><\/i><span style=\"font-weight: 400;\"> have higher BMRs than non-athletes because the mass of their high-metabolic-rate organs (particularly the heart, kidneys, and liver) scales more strongly with overall body size than the relationship observed in non-athletes. So, at a given level of total fat-free mass, athletes tend to have BMRs that are about 10-12% higher than non-athletes. However, this difference is larger for larger athletes, and smaller for smaller athletes.<\/span><\/p><p><span style=\"font-weight: 400;\">This BMR difference is observed at all levels of athletic performance \u2013 both recreational athletes and elite athletes have higher BMRs than non-athletes, but there aren\u2019t major BMR differences between recreational athletes and elite athletes. Furthermore, the impact appears to be similar for all different types of athletic performance \u2013 strength\/power athletes, endurance athletes, and athletes in sports with mixed demands all appear to have BMRs that are elevated to a similar degree.<\/span><\/p><p><span style=\"font-weight: 400;\">You can\u00a0<\/span><a href=\"https:\/\/macrofactor.com\/athlete-bmr\/\" target=\"_blank\" rel=\"noopener\">learn more about the impact of athletic status on BMR here<\/a><span style=\"font-weight: 400;\">.<br \/><\/span><\/p><h3>The impact of weight loss<\/h3><p><a href=\"https:\/\/macrofactor.com\/weight-loss-bmr\/\" target=\"_blank\" rel=\"noopener\">While you\u2019re losing weight<\/a><span style=\"font-weight: 400;\">, your BMR decreases. Part of this decrease is due to the loss of body mass \u2013 it takes less energy to fuel a smaller body, after all \u2013 and part of this decrease is due to \u201cmetabolic adaptation.\u201d Metabolic adaptation refers to decreases in metabolic rate that are disproportionate to the amount of tissue lost. Fears of metabolic adaptation are often blown <\/span><i><span style=\"font-weight: 400;\">way<\/span><\/i><span style=\"font-weight: 400;\"> out of proportion (i.e., fears of entering \u201cstarvation mode\u201d), but we <\/span><i><span style=\"font-weight: 400;\">do<\/span><\/i><span style=\"font-weight: 400;\"> tend to find that BMRs decrease during weight loss to a level that\u2019s about 5-10% lower than we\u2019d expect to observe in people with similar characteristics at energetic maintenance.<\/span><\/p><p><span style=\"font-weight: 400;\">However, about half of the metabolic adaptation that occurs during weight loss goes away once you complete your diet and enter a state of weight maintenance. Research on people who\u2019ve lost significant amounts of weight, and maintained their weight loss over time, find that their BMRs are only 3-5% lower than people who aren\u2019t in a weight-reduced state, on average. In real terms, that\u2019s generally a difference of just 30-100 Calories per day.<\/span><\/p><p><span style=\"font-weight: 400;\">You can\u00a0<\/span><a href=\"https:\/\/macrofactor.com\/weight-loss-bmr\/\" target=\"_blank\" rel=\"noopener\">learn more about the impact of weight loss on BMR here<\/a><span style=\"font-weight: 400;\">.<br \/><\/span><\/p><h3>The impact of weight gain<\/h3><p><span style=\"font-weight: 400;\">Unlike weight loss, we don\u2019t typically observe \u201creverse\u201d metabolic adaptation\u00a0<\/span><a href=\"https:\/\/macrofactor.com\/weight-gain-bmr\/\" target=\"_blank\" rel=\"noopener\">when people gain weight<\/a><span style=\"font-weight: 400;\">. For unknown reasons, BMR <\/span><i><span style=\"font-weight: 400;\">does<\/span><\/i><span style=\"font-weight: 400;\"> appear to immediately increase by about 5-10% when people begin intentionally overfeeding, but this isn\u2019t a metabolic \u201cadvantage\u201d that\u2019s maintained over time. During periods of sustained weight gain, BMR tends to increase in a manner that\u2019s proportional to the tissue that\u2019s gained. In other words, BMR during periods of weight gain is very similar to BMR during periods of weight maintenance.<\/span><\/p><p><span style=\"font-weight: 400;\">You can\u00a0<\/span><a href=\"https:\/\/macrofactor.com\/weight-gain-bmr\/\" target=\"_blank\" rel=\"noopener\">learn more about the impact of weight gain on BMR here<\/a><span style=\"font-weight: 400;\">.<br \/><\/span><\/p><h3>What is the range of normal human BMRs?<\/h3><p><span style=\"font-weight: 400;\">At the extremes, researchers have observed BMRs as low as 700 Calories per day in patients with anorexia, and as high as 3700 Calories per day in exceptionally muscular athletes. But, on average, most women tend to have BMRs between about 1300 and 1600 Calories per day, and men tend to have BMRs between 1700 and 2100 Calories per day.<\/span><\/p><p><span style=\"font-weight: 400;\">However, plenty of people have BMRs that\u00a0<\/span><a href=\"https:\/\/macrofactor.com\/range-of-bmrs\/\" target=\"_blank\" rel=\"noopener\">fall above or below these relatively narrow ranges<\/a><span style=\"font-weight: 400;\">. In representative research on people in the general population, we sometimes see women with BMRs below 1000 Calories per day or above 2400 Calories per day, and men with BMRs below 1100 Calories per day or above 2800 Calories per day. So, don\u2019t be too surprised if your BMR is above or below the relatively narrow \u201cnorms\u201d you may have encountered previously.<\/span><\/p><p><span style=\"font-weight: 400;\">You can\u00a0<\/span><a href=\"https:\/\/macrofactor.com\/range-of-bmrs\/\" target=\"_blank\" rel=\"noopener\">learn more about the range of human BMRs here<\/a><span style=\"font-weight: 400;\">.<br \/><\/span><\/p><h3>Why is this BMR calculator better?<\/h3><p><span style=\"font-weight: 400;\">This BMR calculator uses a\u00a0<\/span><a href=\"https:\/\/macrofactor.com\/macrofactors-bmr\/\" target=\"_blank\" rel=\"noopener\">novel set of formulas that extend and build upon<\/a><span style=\"font-weight: 400;\"> the (already very good) Cunningham and Oxford\/Henry equations. Namely, there were four obvious areas where these formulas could be improved.<\/span><\/p><p><span style=\"font-weight: 400;\">First, they\u2019re both linear equations. However, we know that metabolic rate actually scales non-linearly (allometrically) with body size. Linear equations can provide a decent approximation of allometric relationships for most people, but they inherently produce less accurate estimates for people who are considerably smaller or larger than average.<\/span><\/p><p><span style=\"font-weight: 400;\">Second, the impact of age on BMR is complex. Age has very little impact on BMR up to about 60 years old, and a much larger impact on BMR past age 60. The Oxford\/Henry equations tackle this problem in a manner that\u2019s relatively effective, but not particularly elegant (they just use entirely different equations for adults aged 18-30, 30-60, and 60+, with differing coefficients that don\u2019t directly reflect the underlying physiological realities of aging), and the Cunningham equation doesn\u2019t directly account for age at all.<\/span><\/p><p><span style=\"font-weight: 400;\">Third, they don\u2019t account for athletic status, which has a very notable impact on BMR. Furthermore, there weren\u2019t pre-existing equations for athletes developed using meta-analytic methods. So, we did the legwork of filling that gap, and developed an equation and BMR calculator that is based on data from 30 studies and nearly 2000 athletes.<\/span><\/p><p><span style=\"font-weight: 400;\">Fourth, none of these equations account for the known metabolic impact of being in an energy deficit (metabolic adaptation) or a weight-reduced state.\u00a0<\/span><\/p><p><span style=\"font-weight: 400;\">So, we built upon a strong foundation, and made key improvements that will help our equations be at least a bit more accurate for everyone (on average), with particularly large increases in accuracy for people aiming to lose weight, athletes, people who are considerably smaller than average, and people who are considerably larger than average. And, instead of only presenting your estimated BMR as a single number (which gives an unwarranted impression of extreme precision), this BMR calculator shows you the research-based range of plausible values, so that you can feel more confident with self-experimentation if your actual BMR (and therefore, your actual energy requirements) turns out to be a bit higher or a bit lower than our single best guess.<\/span><\/p><p><span style=\"font-weight: 400;\">You can\u00a0<\/span><a href=\"https:\/\/macrofactor.com\/macrofactors-bmr\/\" target=\"_blank\" rel=\"noopener\">read more about our methodology for developing these equations here<\/a><span style=\"font-weight: 400;\">.<br \/><\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>BMR Calculator: How many calories does your body burn at rest?
