4 Impactful Calorie-Burning Factors & Fun Facts

Burn Calories: The ‘What’ Factors Behind It All

What is the first thing people start tracking when thinking about losing, gaining, or maintaining weight, improving health, and achieving overall wellbeing? Yes, the big C – calories. Maybe you’ve noticed this on the display of your new Trojan home gym machine equipment, such as treadmills, exercise bikes, spinners or ellipticals, and rowers.

It displays your heart rate and the calories being burnt, among other things. Maybe you’ve also noticed that men burn more calories than women? So what do calories actually mean, and why do different people burn calories at different rates, even during the same workout?

Let’s look at 4 impactful factors to understand and determine how many calories your body burns during exercise, which can help you maximise your workout.

#1: Age & Gender

Unfortunately, your age and gender partly determine how many calories you burn when exercising. Men burn more calories than women because they have more muscle tissue and less fat than women. In fact, a man’s metabolism is about 10-15% higher than that of a woman’s. Age, on the other hand, affects caloric burn, because you lose muscle tissue, which slows down your metabolism. The only way to maintain muscle tissue is by performing strength-training exercises at least twice a week.

#2: Body Weight

Simply put, the more you weigh, the more calories you burn when exercising. Your body uses more energy and works harder to move when you weigh more. More prominent built people also have larger internal organs (such as the heart, liver, kidneys, and lungs), which is a significant factor in how many calories are burned during exercise and at rest because these organs’ and processes require energy.

This is where it gets complicated – your body burns fewer calories as your weight decreases, leading to a weight loss plateau or even regaining weight… If you experience this, we suggest working with a registered dietitian specialising in weight loss to help you meet your goal healthily and sustainably.

3#: Your Choices of Exercises

Some exercises burn more calories than others because of the challenge levels. If more muscle fibres are used, the more calories get burned in the process. Walking for 30 minutes on an even surface burns fewer calories than jogging for the same time on the same surface. Elliptical machines have been proven to be more effective during cardio as they engage more muscles at once, burning more calories. Surprisingly, strength training promotes caloric burn in the long run, even when you’re at rest. Why do you think most trainers recommend keeping the rest period to a maximum of 60 seconds?!

#4: Fitness Level

The rate of losing weight changes with time. If you’ve been working out for quite a while, you’ll know that progress, in the beginning, was at a steady pace and kept slowing down as your body got used to the exercise regimen and required less and less energy to get through the workout. That’s why you need to do more challenging exercises that engage more and larger muscle groups to push your body to use more energy and burn more calories.

These are the most general factors influencing the number of calories you burn, and it is essential to keep track of the calories your body is burning during a particular physical activity. There are various calculators, and of course, all Trojan’s machines can show you the same…

 Calorie Burning Fun Facts

  • By singing one song, a person can burn 10 to 20 calories. Now, count how many songs you sing along to and thus burn calories while driving somewhere.
  • Depending on the physical constitution and intensity, you can burn up to 40 calories while laughing.
  • Kissing burns 2 calories per minute. Energy expenditure for 10 kissing minutes equals calories burned walking for 10 minutes.
  • Some house chores can burn more calories than low-intensity workouts. Sweeping and then vacuuming each for 10 minutes, an average person can burn around 74 calories. It’s a bit more than calories burned biking for 20 minutes at a slow pace.
  • While sleeping, an average person burns 68-91 calories per hour. The number is less than any activity while we are awake. But calories burned sleeping have hidden value, as a shortage of sleep takes its toll on health and weight.
