But did you know that our metabolic rates aren't that different after all?
The U.K.'s National Health Service defines metabolism as "all of the chemical processes that go on inside your body to keep you alive."
These various processes need energy, with about 70 percent of the energy being allocated to some of the very basic processes that keep us alive, regardless of our activity levels. This is called the basal metabolic rate (BMR).
Think of metabolism as the body's ability to turn the food you eat into energy that powers different processes in the body.
Researchers have two different methods of measuring basal metabolic rate. First is by measuring the heat the body exudes, and second is by monitoring the levels of carbon dioxide you exhale.
But is there a way to determine if people have a "fast" metabolic rate or a "slow" one? Dr. Thomas Barber, an associate professor and honorary consultant endocrinologist at the University of Warwick and University Hospitals Coventry and Warwickshire in England, said that while individuals have different metabolic rates, in general, our metabolism per unit or kilogram of lean mass "is remarkably constant across the population."
Dr. Barber added that most of the metabolism occurs in all the lean tissue in the body or everything that's not fat. Take note that aside from the muscles, lean mass includes organs like the brain, kidneys, and the liver. When discussing rate in "lean mass, people are fairly similar across the board."
The differences in our metabolism are often because of discrepancies in "the amounts of fat compared to lean mass in a person's body." Dr. Barber explained that if a person has less body fat and more lean mass, their body's metabolism will run more efficiently.
For instance, if two people weigh the same but one has 50 percent body fat and 50 percent lean mass while the other only has 10 or 15 percent body fat, the individual with more lean mass will usually have a higher metabolic rate.
Dr. Barber shared that if you want to change your metabolic rate, you'll also need to change your "fat-to-lean-mass ratio." Since your body fat and lean mass affect each other, regular exercise will have the same positive effect.
He advised that increasing your lean mass and reducing your fat mass is one way to improve your metabolism. This can be done by exercising more, which will build muscle and help you gain lean mass. This can positively affect your overall metabolic rate. Dr. Barber also warned that changing your metabolic rate medically might have dangerous side effects.
He pointed out that using different metabolic rates as an excuse for living an unhealthy lifestyle can cause weight gain.
However, he noted that losing weight can sometimes be a struggle, especially since even your body might "fight back against weight loss." If you really want to lose weight, you have to be prepared to handle some "quirks of metabolism." (Related: The best metabolism-boosting foods to help you lose weight and KEEP it off.)
The human body will naturally want to maintain its weight. If you manage to lose at least five or 10 percent of your weight, the mechanism known as "persistent metabolic adaptation" will start to slow down your metabolism. It can even increase your appetite to make your body return to the weight it thinks if your default weight. Dr. Barber said that this is a hurdle that most people trying to lose weight have to face.
Even if you lose weight, you still need to work out more and stay active so you can maintain your current weight. Losing weight takes some time and hard work on our part, but the various health benefits of weight loss should be enough to get us started on the long road to fitness.
When you're not working out in the gym, you can eat some of the metabolism-boosting foods below so you can effectively lose weight:
