The word “calorie” may bring up thoughts of nutrition labels and treadmill readouts, but calories are actually units of energy. Your car runs on gas, your house runs on electricity and your body runs on food energy. So how many calories to do We burn every day, and how much should Are you burnt out? Let’s dig in.
You actually burn most of your calories at rest
Calories are not only burned during exercise. It takes energy to keep the lights on, so to speak—for your heart to beat, your brain to think, your cells to repair themselves, and more.
in fact, the most Our calories are burned in these maintenance tasks. Scientists call this baseline calorie our “basal metabolic rate” or BMR. There are several equations that will estimate your BMR; For a calculator, try one tdeecalculator.net. (It uses the Mifflin-St. George formula if you don’t know your body fat percentage, and the Catch-McArdle formula if you do.)
To give you an example, I plugged in my stats—I’m 150 pounds and 5’6”—and the equation predicts someone my size burns:
-
1,352 calories for most of my basic bodily functions (not including digestion!).
-
1,623 calories, total, if I’m sedentary
-
A total of 2,096 calories if I do moderate exercise three to five times a week
-
2,569 calories, total, if I’m a hardcore athlete or someone who exercises on top of a physical job
Keep in mind that these are just estimates; Yours real Calorie burn can be more or less. (From tracking my calories over the years, I know I’m usually somewhere between those last two numbers, depending on how active I am.) Factors that affect your total calorie burn include:
-
body size: The older you are, the more calories you burn at baseline And The more you burn during exercise.
-
muscle mass: Muscle burns more calories than other tissues, so if you know your body fat percentage you get a more accurate estimate; The less body fat you have, the more muscle you have in comparison.
-
Age: These formulas assume that your metabolism slows down a bit as you age (although there is evidence that This will not make a big difference).
-
activity: The more you exercise, the more calories you burn.
-
Genetics and other factors are not considered in the formula: There really is Huge Variation from person to person, even if you compare people of similar size, age, etc. We are all different.
To give you a sense of the series, the 2020-2025 Dietary Guidelines for Americans Two examples are calorie counts for people, both of which are slightly smaller than the average American, but let’s take a look anyway. Document statistics show that a 5’10” man weighing 154 pounds will burn, in total, Between 2,000 and 3,000 calories per day, depending on his age and activity level. His example is a female 5’4” and 126 pounds, and she will burn Between 1,600 and 2,400 calories.
So if you’re used to thinking of 2,000 calories as an upper limit on how much to eat—or 1,200 calories as a calorie budget for dieting– You might be surprised at how many calories you’re consuming already Burn
How (and why) to burn more calories
If you’re trying to lose weight, logic would say you should focus more on diet than exercise. After all, if most of your calorie burn is your BMR, exercise will drop in the bucket in comparison.
I don’t think that’s the only thing you should consider. If your BMR is 1,300 calories and your total burn is 1,600, sure, you can eat 1,300 calories without exercise and probably lose weight. But it’s hard to stay healthy when you eat so little.
Burning more calories through exercise helps your body in two ways:
What do you think so far?
-
Regardless of calorie burn, exercise is good for us; We should all get at least 150 minutes of cardio per week, plus some strength training to help build or maintain muscle.
-
The more food you eat, the easier it is to fit in the good stuff: vitamins, minerals, fiber, good fats, and a variety of vegetables.
A person who burns 2,300 calories and eats 2,000 is in a much better position to benefit from exercise and good nutrition than someone who burns 1,600 and eats 1,300.
So how do you burn more calories? You can’t get any younger, and if you’re losing weight, you don’t want to get any bigger. The biggest levers you can pull are:
-
Exercise more
-
Gain muscle mass (through strength training, and eating plenty of protein)
-
Don’t diet all the time
I have written about how before I noticed that my total calorie burn increased when I ate more food; When you feed your body, it is more willing to expend energy. This is one of the reasons why it is considered beneficial to take “diet breaks” if you plan to stay in the weight loss phase for an extended period of time.
Why you shouldn’t rely on “calorie burn” numbers from wearables or exercise machines
You may be wondering how much exercise is “enough” to burn more calories. That’s a trick question, though: what kind of change do you want to make? the person You – stop being sedentary and become a frequent exerciser – know for yourself exactly how many numbers you burned in which workout instead of nickel-and-dime.
This is the reason Our bodies become more efficient with exercise over time. Half an hour of jogging can burn 300 calories In theoryBut at the end of the day you might just burn, say, 200 more than if you hadn’t jogged. You may feel more tired later in the day, or you may get better at running and burn fewer calories when you do. (This is an ongoing area of scientific research.)
There is evidence Calorie burn estimates from exercise machines are highly imprecise; Wearables like Fitbits and Apple watches are probably a bit better, personalizing your exercise intensity, but they still ultimately rely on estimates that aren’t always accurate.
