How To Tell if You Have a Fast Metabolism

Metabolism refers to the chemical processes occurring within a body to maintain life. These processes, among other things, are in charge of breaking down of calories to meet the energy needs of your body. Therefore, metabolism plays a significant role in determining whether you accumulate weight easily or not.

Overweight people need a faster metabolism, while underweight people want exactly the opposite. You may think that a fast metabolism is healthier or better, but that is quite far from the truth: in fact, people who have a fast metabolism tend to experience several health problems.

Here at oneHOWTO we are going to talk about how to tell if you have a fast metabolism, its causes and ways to slow it down.

What are the symptoms of a fast metabolism?

The easiest way to tell if you have a fast metabolism is to check the most common symptoms. However, this does not mean that everyone who has a fast metabolism shows every item on this list. If you want to know for sure, you should take blood test to accurately measure your metabolic rate. A person who has a fast metabolism may experience the following:

Being underweight

The Body Mass Index (BMI) of a person with a fast metabolic rate is comparatively lower than the desired value, as per the person’s height, age and body type.

High basal body temperature

A person with a fast metabolism feels sweaty and hot all the time, since their basal body temperature remains high. When the body temperature or the exterior temperature go lower, metabolism tends to slow down.

Being hungry

A person with fast metabolism feels hungry all the time, even if they have the 5 recommended meals everyday. Sometimes, they may feel empty immediately after eating food. This is a sign that their metabolism is at its peak speed.

Irregular menstruation

Young girls who are on their way to puberty may have problems in their menstrual cycles. Their cycle may be irregular, or they may begin late. This is because these girls with fast metabolism do not have the needed amount of body fat to start or continue normal menstrual cycles. They look thinner, and have less energy level just before and after the cycles.

What is hyperthyroidism?

There are several causes of a fast metabolism. One of them is hyperthyroidism, a condition that is characterized by excessive thyroid hormone production in the thyroid gland.

One of the main consequences of this condition is precisely a fast metabolism. If you have not yet been diagnosed and you also have the following symptoms, you may have hyperthyroidism:

  • Frequent bowel movements
  • Dizziness, excessive sweating and fatigue
  • Rapid heart rate
  • Trouble sleeping
  • Frequent mood swings
  • Trembling hands

How to slow down a fast metabolism

If you have a fast metabolism, you may want to slow down the process in order to stay within your ideal weight range and prevent related problems.

Eat correctly

The first thing you can do is to make your food choices wisely. Eat at least 500 calories more than you usually would. To do this healthily, you should eat foods that metabolize slowly and that have more calories such as nuts, meat and dairy products. Make sure you eat your meals with plenty of time in between to slow down your metabolism and help normal digestion.

Relax after eating food

Do not do heavy work or exercise immediately after eating, as it will cause your food to digest faster and your metabolism will speed up. Do not exercise for more than half an hour a day, and avoid doing any strenuous activities. Avoid burning calories through heavy workout routines, and opt for softer exercise instead.

You can maintain your muscle tone with a fast metabolism, but it is not healthy to burn your fat reserves completely.

Sleep less

A person with a fast metabolism should get 6-7 hours of deep sleep everyday. A little less sleep will increase cortisol levels in your body, thus slowing down your metabolism and storing fat in your body.

What to do if you have a fast metabolism

If you experience any of the symptoms and side effects of a fast metabolism and want to slow it down, it is advisable that you first consult your doctor. They will give you the information needed on diet and exercise so that you know how to slow down your metabolism correctly and safely.

Didn't really answer my question....

Hi Mikou, what was it you wanted to let us know? If you let us know maybe we can add some more info!
Not exercising for more than 15 minutes a day is not an option for some people, including me. It is such a crucial part of living.
OneHowTo Editor
If you're practicing some kind of competitive sport it's normal to be exercising for more than 15 minutes a day. In these cases it's important to make sure you get a great amount of carbs 2 hours before you practice it.
However, if you love exercising, we recommend you focus on anaerobic exercises instead of cardio.

Hope this info was useful
doesnt matter
im guessing the person who wrote this article has a slow metabolism, and is 100% bias against people with a fast metabolism, did the person list any bad effects of having a slow metabolism? NO, are there any bad effects of having a slow metabolism? YES,
OneHowTo Editor
Dear doesnt matter, This article is just a guide to know if you have fast metabolism or not. It is not telling you if it's good or bad to have one, but it gives you the gidelines to know if you do have it and how to live with it. Hope this helps.
