Factors Affecting Your Metabolism

Metabolism is a collection of chemical reactions that helps your body get the necessary energy from food. This energy is necessary for your body to sustain its essential functions. The speed at which your body burns calories is your metabolic rate. A fast metabolism or high basal metabolic rate (BMR) helps in weight loss. And that’s not all. A healthy metabolism is necessary for the overall health of your body. There are various factors that can affect how fast or how slow your metabolic rate is. Here are some of them:
Age
Your total lean muscle mass is largely responsible for your BMR. After the age of 30, the body begins to lose its lean muscle mass. This leads to a decline in your metabolism. Expect your metabolic rate to decrease by 2% every decade after the age of 20. You can increase your metabolism by increasing your physical activity after the age of 30.
Gender
Since men have more lean muscle mass, their metabolism is higher than women. This is why women tend to gain weight more rapidly than men and need to work harder to boost their metabolism.
Height
If you are tall, your body has a higher surface area to sustain. This means that your body needs more energy than a short person. As a result, the taller you are, the more active your metabolism and the more calories you need to stay energized.
Genetics
We have all known people who do not gain weight inspite of being heavy eaters. And then there are those who end up gaining weight although they eat normally. This is because of the differences in their genetic makeup. Your BMR is inherited and there is not much you can do to change it. However, knowing your BMR will help you do the needful to raise your metabolism.
Eating Habits
Some foods increase your metabolism and some slow it down. How and when you eat are also factors which may decrease or increase your metabolism. If you eat small meals throughout the day rather than one huge meal a day, your metabolism will be more active.
Stress
If you are under constant stress and pressure, your metabolism will be slow. You can increase your metabolism by managing your stress effectively.
Hormonal balances
Different nutrients are metabolized by different hormones in the body. Correcting a hormonal imbalance can increase a sluggish metabolism.
Physical activity
Increasing your physical activity and exercising is the best way to increase your metabolism. Aerobics and working with weights increases lean muscle mass and increases metabolism. If you have a sedentary lifestyle, your metabolic rate will be slow. Any kind of physical activity requires more energy for your body. This means that your metabolism will speed up to burn more calories to produce more fuel to carry out the bodily movements.
A healthy metabolism is necessary to create new cells and tissues, maintain the body’s temperature, repair injuries, and perform bodily activities. Although there is nothing you can do about factors such as your genetic makeup and your height, a healthy diet and the right fitness routine can help increase your metabolism to the appropriate level and contribute to your overall health.
