When it comes to losing weight, one of the most important things to consider is how many calories your body burns each day. Knowing this number can help you create a calorie deficit, which is necessary for weight loss. In this article, we will discuss how many calories your body burns a day and provide tips on how to increase your calorie burn.
What is Basal Metabolic Rate (BMR)?
Basal Metabolic Rate (BMR) is the number of calories your body burns at rest. This means that BMR is the number of calories your body needs to carry out basic functions like breathing, circulating blood, and maintaining organ function. BMR accounts for about 60-70% of your total calorie burn each day.
How to Calculate Your BMR
There are many BMR calculators available online, but the most accurate way to calculate your BMR is to get a professional assessment. However, you can still get a rough estimate by using the Harris-Benedict equation:
BMR for men = 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) - (5.677 x age in years)
BMR for women = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) - (4.330 x age in years)
Example Calculation:
Let's say you're a 30-year-old woman who is 5'5" (165cm) tall and weighs 140lbs (63.5kg).
BMR = 447.593 + (9.247 x 63.5) + (3.098 x 165) - (4.330 x 30)
BMR = 1,359 calories per day
What Factors Affect BMR?
There are several factors that can affect your BMR:
- Age: BMR decreases with age
- Gender: Men typically have a higher BMR than women
- Body Composition: Muscle burns more calories than fat, so people with more muscle mass have a higher BMR
- Hormones: Thyroid hormones, for example, can affect BMR
- Genetics: Some people have a naturally higher or lower BMR
How Many Calories Does Your Body Burn During Physical Activity?
In addition to BMR, your body burns calories during physical activity. The number of calories you burn during exercise depends on several factors, including:
- Intensity of the exercise
- Duration of the exercise
- Your body weight
- Your fitness level
On average, a 155-pound person can burn the following number of calories during 30 minutes of physical activity:
- Running (8mph): 465 calories
- Biking (14-16mph): 335 calories
- Swimming (moderate): 235 calories
- Walking (3.5mph): 140 calories
How to Increase Your Calorie Burn
If you're looking to lose weight or improve your overall health, there are several ways to increase your calorie burn:
- Exercise regularly
- Build muscle through strength training
- Stay active throughout the day
- Eat a balanced diet
- Get enough sleep
Frequently Asked Questions (FAQ)
Q: How do I know if I'm burning enough calories to lose weight?
A: To lose weight, you need to create a calorie deficit, which means you need to burn more calories than you consume. A safe and sustainable rate of weight loss is 1-2 pounds per week. To achieve this, you should aim to create a calorie deficit of 500-1000 calories per day through a combination of diet and exercise.
Q: Can I increase my BMR?
A: Yes, you can increase your BMR through strength training, building muscle, and staying active throughout the day. Eating a balanced diet and getting enough sleep can also help.
