RMR supports breathing, circulating blood, organ functions, and basic neurological functions. Resting metabolic rate is the total number of calories burned when your body is completely at rest. * Non-exercise Activity Thermogenesis: Energy expended for everything you do that does not include sleeping, eating, physical activity or exercise – ranges from simple standing to fidgeting and moving about.Ĭan we calculate our RMR? Can we influence it or is it predetermined? Let’s examine these questions more closely. The thermic effect of physical activity (TEPA): the energy of activity (e.g., exercise, physical activity) and non-exercise activity thermogenesis (NEAT).*.The thermic effect of food (TEF): the energy cost of chewing, swallowing, digesting, absorbing and storing food.Resting metabolic rate (RMR): the energy required to keep your body functioning at rest.Our TDEE is essentially comprised of three components: But for most of us, it refers to total daily energy expenditure and how it influences our energy in versus energy out equation. Scientific references to metabolism refer to the bodily processes needed to maintain life. Assessing Starvation States for Optimal RMR.But before we dive into RMR, let’s take a look at the components of total daily energy expenditure (TDEE). Our resting metabolic rate (RMR) plays a significant role in this, and it’s understandable why it garners so much attention. This is an outcome of enhanced caloric expenditure, increased lean body mass, greater fat utilization and overall weight loss. To the general public, boosting your metabolism is associated with the transformation from ‘fat-to-fit’ or ‘flab-to-fab’. As a nutrition coach or weight loss specialist, this is a topic you may get asked about from time to time. Total Energy Expenditure + Energy DepositionĠ-3 months EER (kcal/d) = (89 x Wt - 100) + 175Ĥ-6 months EER(kcal/d) = (89 x Wt - 100) + 56ħ-12 months EER (kcal/d) = (89 x Wt - 100) + 22ġ3-36 months EER (kcal/d) = (89 x Wt - 100) + 20ĮER (kcal/d) = 88.5 - 61.9 x Age + PA x (26.7 x Wt + 903 x Ht )ĮER = 135.3 - (30.Mention the term ‘metabolism’ and it captures attention given how obsessed many of us have become over calories. IOM - Estimated Energy Requirement (EER) Equations:Įstimated Energy Requirement (kcal/day) = OR 120 minutes of additional moderate activity Miles), rope skipping, skating, swimming, tennis (doubles), walking (5 mph) Wood, climbing hills (no load), cycling (moderately), jogging (10-min Very Active: (Daily PAL range: 1.9 - 2.5): (leisurely), golf (without cart), swimming (slow), walking 3-4mph, etc.Īctivity daily such as calisthenics (no weight), cycling Moderate activity daily such as calisthenics (no weight), cycling Low Active: (Daily PAL range: 1.4 - 1.59): Sitting, loading/unloading car, mopping, mowing lawn (power mower), etc. Sedentary: (Daily PAL range: 1.0 - 1.39):Īs gardening (no lifting), household tasks, light activity while The activity level below will be used along with theĪge-specific EER equation to calculate an estimate of the number of calories needed per day (kcal/day) This initial version will estimate energy requirements >Physical Activity Coefficients (PA) for the various age groups that are used Physical Activity Level (PAL) is the ratio of total energy expenditure to basalĮnergy expenditure (TEE/BEE). The physical activity coefficients are used in the EER equations to estimateĮnergy requirements and are based on ranges of physical activity levels. 'Physical Activity Coefficients (PA)' and the 'Physical Activity Levels (PAL).' When using the EER equations, it is important to distinguish between the Thermoregulation, and the energy expended in depositing new tissues and in Metabolic rate, TEF (thermic effect of food), physical activity, Measurement.) Total Energy Expenditure (TEE) is the sum of the basal Water database (considered the gold standard for Total Energy Expenditure
