Calorie counting can be an intimidating process. There are so many calculators and complex equations out there that can make this task increasingly complicated, leading to unpredictable and sometimes unpredictable results.
Your daily food consumption provides energy to fuel daily activities and exercise, thus helping maintain bodyweight and regulate fat.
BMR
Your basal metabolic rate (BMR) measures how many calories your body burns at rest while performing minimal physical activity, such as breathing and cell production, maintaining body temperature or breathing through respiration. There are various methods available to you for calculating this number, including direct calorimetry or indirect calorimetry methods and online calculators such as Harris Benedict equation or Mifflin St Jeor formula calculators to assist in this calculation process.
No matter if your goal is to lose or gain weight, knowing your basal metabolic rate (BMR) is an essential step towards reaching them. But simply knowing this number doesn’t provide all the answers to help achieve those goals; other factors, like muscle-to-fat ratio, health conditions and hormone levels all affect how you respond to diets; therefore attempting to lose or gain weight by simply eating less than your BMR could backfire and even be harmful; for this reason using either an AMR calculator or your own calculation could provide more accurate answers about how many calories your body requires.
TDEE
Total Daily Energy Expenditure (TDEE) measures the total daily calorie expenditure over 24 hours, accounting for BMR and physical activity plus food digestion’s thermic effect. TDEE serves as an important measure of balance between calories in and calories out, which is key in reaching specific weight-related goals such as loss or gain.
Calculations of Total Daily Energy Expenditure (TDEE) begin by determining your basal metabolic rate (BMR), followed by multiplying this figure by an activity factor that takes into account not only intentional exercise but also non-exercise activity thermogenesis – or burning off energy while not physically exercising – during everyday activities that don’t qualify as actual workouts.
Notably, TDEE formulas tend to be based on general population averages which may lead to overestimation or underestimation of your caloric needs. Furthermore, your body composition and hormonal fluctuations can have an effect on metabolism that aren’t always fully taken into account by standard TDEE formulas; for this reason it may be wiser to have your TDEE calculated by an experienced professional.
TBW
Total Body Water (TBW) measures an individual’s total body fluid content and can be estimated by multiplying their weight in kilograms by 0.73. It serves as an important indicator of health and can help determine how much water one should drink each day to stay hydrated.
There are various methods of estimating total body water weight (TBW), such as skinfold-thickness measurements, bioelectrical impedance analysis (BIA), Xitron Hydra and underwater weighing. Most of these provide only rough estimates and may lead to inaccurate results.
Isotope dilution with deuterated water is the most accurate means of measuring Total Body Water (TBW). Participants consume a known dose of deuterium oxide and allow it to mix with their body fluid before taking samples for measurement with stable-isotope mass spectrometry. This method can also be used to monitor changes over time in TBW, making it a useful way of monitoring hydration status during and post exercise; unlike free water deficit which does not take into account ongoing losses of water (TBW does).
Activity Level
People living active lives tend to burn more calories than those with more sedate lifestyles, due to physical activity and workout routines that consume energy each day. Exercise may only make up part of an individual’s total energy expenditure – digestion and breathing require energy as well.
Total daily energy expenditure (TDEE) refers to the total of BMR, NEAT and exercise – an estimate used to help determine if weight loss or maintenance is needed.
A calorie maintenance calculator is an online tool designed to estimate how many calories you require in order to maintain your current weight, taking into account factors like age, gender, height and weight to provide an accurate estimation.

Calculation is straightforward and only requires your personal details. Simply input them into the calorie maintenance calculator, follow its instructions, and find your TDEE. This will enable you to manage your diet more effectively and ensure that you’re consuming an appropriate amount to maintain weight.
