We’ll get to that after you calculate how many calories your body needs. The more complex answer is, however, ‘yes, but there are a few things that can affect weight management and lean muscle mass retention’.

The amount of energy you consume directly affects your body composition – full stop – so you need to know how much to eat every day. If you eat more calories than your body uses up, it’ll store the excess energy as body fat, which over a long period of time can cause unwanted weight gain. But is it really a simple case of calories in, calories out? Being armed with this knowledge, rather than guesstimating or blindly following a plan without scaling it to your individual needs, can make or break your muscle gains or fat loss.If you’ve ever tried to lose weight, you’ve probably heard of calorie counting. Once you use your BMR to determine your TDEE, you can make sure that the nutrition plan you follow is appropriate for your level of energy expenditure and that it isn’t giving you too many or too few calories.

HOW TO USE YOUR BMR TO LOSE FAT OR GAIN MUSCLE If the equation uses RMR, use this RMR calculator, which will give you a higher number. If it’s based on BMR, you can use the calculator above to get an estimate. Unless you’re being tested in a lab environment, both of these numbers will only be estimates, but they can still give you targets to shoot for when you structure your meal plan and workouts.īMR and RMR numbers are typically close enough to be interchangeable, but if you’re calculating your needs in order to gain or lose weight, pay attention to which number an equation calls for. Since the calories you burn digesting food and doing things like brushing your teeth tend to stay around the same range on most days, either number can be used when you’re just trying to get a rough estimate of how many calories you burn not including your workouts. The term BMR is sometimes used synonymously with RMR, which stands for “resting metabolic rate.” The difference is that while BMR only measures basic processes of breathing, blood circulation, and temperature regulation in a completely resting state, RMR also includes energy expended by digestion and non-exercise daily movements, like getting dressed and lifting your fork to your mouth.

WHAT’S THE DIFFERENCE BETWEEN BMR AND RMR? Keep in mind, though, that it’s impossible to know your exact TDEE, as your activity levels will change day to day, and the only way to get 100 percent accurate BMR numbers is through laboratory testing. You can use a TDEE calculator to find this number, or calculate it manually to get a more specific result. Generally, men have a higher TDEE than women because they have more muscle mass, and both TDEE and BMR tend to fall regardless of gender as you age. This varies significantly based on your activity level, age, and sex. It’s determined based on your BMR as well as your activity level throughout the day. The overall number of calories your body uses on a daily basis is referred to as your “total daily energy expenditure” (TDEE). From there, you can determine how many calories you need to eat to gain muscle, lose fat, or maintain your weight. Once you know your BMR, you can use it to calculate the calories you actually burn in a day. This means that when you have a lot of muscle mass, you’ll burn more calories at rest. However, increasing muscle mass does increase BMR, because muscle is metabolically “hungry” and it takes more energy to maintain more muscle. Since your basal metabolic rate is based largely on involuntary functions like breathing and pumping blood, changes in your day-to-day activity don’t do much to raise or lower this number. You can think of it as the amount of energy you’d burn if you stayed in bed all day.

Your BMR is the number of calories your organs need to function while you perform no activity whatsoever. This minimum number is called the basal metabolic rate (BMR). Everybody requires a minimum number of calories to live.
