What Is Metabolism?
Metabolism is the process in which your body turns the food you consume into energy that you need to function. Even when it looks like you’re not doing anything to spend energy, your body is constantly burning calories for involuntary functions like breathing, blood circulation, cell repair, and growth. This means that you are burning calories even outside your gym sessions!
The energy that your body uses for these basic, involuntary functions is called the basal metabolic rate. Several factors affect how fast or slow metabolism is, and oftentimes, people refer to the basal metabolic rate when they talk about “fast” or “slow” metabolism. These factors are age, body size and composition, genetics, and sex.
Is Slow Metabolism To Blame for Obesity?
Metabolism is likely not to blame for obesity. A metabolism slow enough to pose any serious health risks is rare. And oftentimes, being overweight or obese is a result of interaction between diet and lifestyle.
There are other more likely factors that contribute to obesity than slow metabolism. Some of these are a caloric surplus, certain medications, genetics, a lack of physical activity, poor sleep and other unhealthy habits. Even engaging in crash diets with harsh calorie restrictions that break down muscle mass can be a factor.
