When it comes to weight gain and weight loss, many people blame it on one scapegoat: metabolism.
Metabolism is a source of confusion for many, with so many metabolism myths. Is it true that thinner folks have higher, more active metabolisms? Is there anything you can do to speed up or slow down the rate of your metabolism?

Defining Metabolism: How Your Body Creates Fuel
Metabolism is the process in which your body converts what you eat and drink into the energy needed to fuel your body. Even when your body is at rest, it needs fuel for all its essential functions, like breathing and circulating blood.
Your metabolic rate (which is what most people refer to as “metabolism”) is the number of calories (or energy) your body uses to fuel these functions.
Each person’s metabolic rate (MR) is different and dependent on a combination of factors, including:
- Body size (height, weight)
- Body composition (fatty tissues vs. muscle)
- Gender (women’s MR is often lower than men)
- Genetics (your specific genetic makeup can affect your metabolism)
- Age (MR tends to slow as you age)
- Climate (MR tends to be higher for people living in warmer climates)
Each of these variables combined determines your individual metabolic rate. So, while it is not a complete myth that your metabolism is linked to your weight, a slow metabolism is rarely the cause of those pesky extra pounds. Instead, factors like diet and exercise are usually the bigger culprits behind weight gain.

Metabolism Myths and Facts
Here are a few other common metabolism myths, debunked:
Myth: Thin people tend to have higher metabolisms
Body composition is a huge factor in your metabolism, but not the way you might suspect.
Contrary to the popular myth, people who are lean tend to have slower resting metabolisms than their overweight counterparts. Larger people tend to have higher metabolic rates, that is, their bodies burn more calories as they rest.
Myth: Green tea boosts your metabolism
Green tea has often been called a natural metabolism-boosting drink. But can it really make your body burn more calories?
Studies have shown, in fact, that drinking green tea can slightly increase the metabolic rate. But this increase isn’t substantial enough to offset the consumption of extra calories.
The same logic applies to other metabolism-boosting items, like red peppers and coffee. Consuming them does produce a slight bump in metabolic rate, but not enough to create a real impact.
Myth: You have no control over your metabolism
As mentioned above, body composition is a critical factor in determining your metabolism. As your body composition changes, so does your metabolism. A few ways to change your metabolism include:
- Lifting weights helps build muscle, which is more metabolically active than fat
- Getting enough sleep
- Drinking enough water
- Decreasing stress through relaxation techniques
