What Causes a Fast Metabolism

For people with fast metabolism, losing and maintaining weight is much easier than others. To start with, metabolism refers to a series of chemical processes which aims at converting the food you eat into energy. The faster metabolism you have, the more calories you will burn and the lesser pounds you will accumulate. Fast metabolism is good for those who are trying to lose weight, but unwelcome for those who are trying to build body and gain fat. So, the choice is entirely yours. Although you may speed up your metabolism with exercise and diet, there are some people who already have a fast metabolism. Here at OneHowTo.com, we are going to find out what causes a fast metabolism.

How to know if you have fast metabolism

First of all, you should know what type of metabolism you already have. Check for the symptoms of fast metabolism, which include being underweight, more hunger and frequent bowel movements.

People with a fast metabolism always have a high basal body temperature, due to which they sweat more and feel hot most of the time. Young girls with fast metabolism may have late and irregular menstrual cycles, probably due to the lack of required fat for the normal cycles. Some people may also experience fatigue, dizziness, rapid heart rate, difficulty sleeping, trembling hands and frequent mood swings. If you encounter any or all of these symptoms, you probably have a fast metabolism.

Causes of fast metabolism

There are several reasons why people have a fast metabolism:

Genes

Your genes definitely play a very important role in determining whether you have slow, fast or normal metabolism. Basically, there are three types of bodies, mesomorphs who have an athletic build, endomorphs who have a bigger body, and ectomorphs who have a thin build. Ectomorphs are know to have the fastest metabolism, due to which they have thin bodies, small shoulders, delicate frame and little muscle mass. Such people will not gain weight and put on muscle, no matter how hard they try.

Overactive thyroid gland

This condition known as hyperthyroidism is usually related to a fast metabolism. It is usually identified by nervousness, rapid heart rate, weight loss and fatigue. Your doctor may decide to take your thyroid test if you are experiencing any of these symptoms.

Smoking

Smoking cigarettes can also be the reason why you may have fast metabolism. It may mess up with your metabolism and add to all the other issues smoking brings with it.

Stress

If you are stressed, it may also have affects on your metabolism and make it faster than normal. So, find ways to relieve your stress, in case you are trying to gain weight and build body.

Disadvantages of fast metabolism

In addition to making you too lean and thin, a fast metabolism brings in more side effects, like irregular menstrual cycles, fatigue, sleeping troubles and rapid heart rate. To summarize, fast as well as slow metabolism are not ideal for your health, and it needs to keep a balance between the two.
