BMR and sedentary lifestyle -

For this reason, your BMR might not give you the full context you need to understand what lifestyle changes you can make to achieve weight loss. The final number is approximately how many calories you need on a daily basis to maintain your weight.

Of course, this is an estimate. According to a study , the formula would be more accurate if it included body composition, weight history, and other factors that have been shown to affect BMR. However, to get the most accurate idea is to have a trained technician perform indirect calorimetry, which is a study of your metabolism.

This test measures how much oxygen O2 you take in and how much carbon dioxide CO2 you take out when you breathe. The quantity of these gases varies depending on how your body metabolizes different macronutrients such as carbs, fats, and protein for energy. Of these factors, you can take steps to change your weight and body composition.

So if you want to change your BMR, your first step should be to increase muscle. For example, a study suggests that resistance training is an effective means of boosting BMR levels among a group of inactive adult women.

Online BMR tests with rigid formulas are not the most accurate method of determining an individual's BMR. It is better to consult a certified specialist or measure BMR through a calorimetry device.

These handheld devices are available in many health and fitness clubs, doctor offices, and weight-loss clinics. While the two are used interchangeably, there is a key difference in their definitions.

Resting metabolic rate, or RMR for short, is the rate at which the body burns energy in a relaxed, but not fully inactive state. It is also sometimes defined as resting energy expenditure, or REE.

BMR measurements must meet total physiological equilibrium while RMR conditions of measurement can be altered and defined by contextual limitations. Essentially, an average person eating an average diet will likely have expected BMR values, but there are factors that are still not understood that determines BMR precisely.

Therefore, all BMR calculations, even using the most precise methods through specialists, will not be perfectly accurate in their measurements.

Not all human bodily functions are well understood just yet, so calculating total daily energy expenditure TDEE derived from BMR estimates are just that, estimates. When working towards any sort of health or fitness goal, BMR can aid in laying down the foundations, but from there on, it has little else to offer.

A calculated BMR and thus TDEE may result in unsatisfactory results because of their rough estimates, but maintaining a daily journal of exercise, food consumption, etc. Tracking progress in said journal and making adjustments over time as needed is generally the best indication of progress towards reaching personal goals.
