Having a High Metabolism

What to do when you have a low or high metabolism.

Metabolism is defined as the number of calories the body needs while at rest. In other words, the body needs a certain number of calories just to sustain bodily functions, like breathing and heartbeat. This number is usually referred to as the basal metabolic rate (BMR).

Is a Low Metabolism From a Sluggish Thyroid?

Because your thyroid controls your metabolism through the secretion of hormones, it is these hormones (and your physical fitness level) that control how fast (or slow) food is converted into energy. If you are having trouble losing weight, it could be that your thyroid is not functioning normally. Your doctor can check it with a simple blood test.

Build up Your Muscles for a Higher Metabolism

One fact we know is that a pound of fat burns about 10 calories while a pound of muscle burns almost 30 calories over the same given period of time. So it makes sense that the more muscle you have, the more calories you’ll burn just to sustain the additional muscle. Because of this fact, gaining lean muscle mass is one way to increase your metabolic rate.

Another way is through physical exercise; exercise triggers an increase in metabolism that can last for several hours after finishing your workout. By incorporating weight training into your routines, not only do you increase your metabolism in the short term, but also permanently through the building of lean muscle mass. A win/win situation!

Is Your Metabolism High, Low or Normal?

But how do you know if you metabolism is low, normal or high? First you have to know your BMR – the number of calories your body needs to function while at rest. If the number you consume is higher, but you are not gaining weight, then you have a high metabolism. To calculate your BMR, use these formulas:

  • women: 655 + (4.3 x weight in pounds) + (4.7 x height in inches) – (4.7 x age in years);
  • men: 66 + (6.3 x weight in pounds) + (12.9 x height in inches) – (6.8 x age in years).

Note the formulas are based on a normal adult body. If you are extremely muscular or very obese, then your resulting figures will be underestimated or overestimated, respectively.

For example, let’s use a 30-year old, 5 ft. 10 in. tall male weighing 170 pounds. Plugging the numbers into the formula 66 + (6.3 x 170) + (12.9 x 72) – (6.8 x 30), we come out with 66 + (1071) + (928.8) – (204) = 1,861.80 calories per day to maintain his current weight. If our study is eating significantly more calories and not gaining weight, then he has a high metabolism. Because he burns calories at a higher rate, it will be easier for him to lose weight just from cutting calories.

While your thyroid basically controls your metabolism, you can help increase its functioning through healthy eating, regular exercise and building of lean muscle mass.

Create a Calorie Deficit

All of us know that cutting calories and exercising more is the secret to healthy weight loss. But how many calories do you need and still have enough to fuel your body? The number you need to eat each day varies depending on your:

  • overall health
  • physical activity
  • sex
  • weight
  • height
  • shape

Because of these variables, experts cannot agree on the number of calories you should consume each day. In the U.S., the average male should eat 2,700 calories per day while in females that number is 2,200; in the UK, the recommendations are 2,500 and 2,000 respectively. The United Nations on the other hand, recommends consuming no less than 1,800 calories per day.

While these are all good guidelines for general information, in the scope of nutrition and weight loss they are generally irrelevant. If you want to lose weight, you have to create a 500 calorie per day deficit between the numbers of calories you eat and the number you expend. There are three ways to accomplish this.

1) Create a Calorie Deficit by Eating Fewer Calories

If you want to keep your physical activity the same, but lose weight, then you have to eat 500 fewer calories than you are currently eating. It is easy to do by making smarter and healthier food decisions. A good place to start is to cut (or at least limit) the calories you consume by watching foods high in simple carbohydrates (sugar) and saturated fat.

Instead of that latte in the morning, choose plain coffee with a little cream. The latte has 180 calories of which 25% is saturated fat. By comparison a tall Starbucks coffee with cream has 20 calories of which 5% is saturated fat.

Eat more foods high in protein, such as chicken, turkey, pork and lean beef. Substituting natural foods – fruits and vegetables – for processed food is also a good way to cut calories.

2) Create a Calorie Deficit by Burning More Calories

However, if you want to keep your calorie intake the same, then you can burn up to 500 more calories each day by adding in more exercise; it is easy. Instead of parking close to your work, park at the far end of the parking lot and walk the rest of the way. During your lunch break, walk around the block a couple of times. You will still have time to eat a healthy lunch that you brought to work. Or go for a walk after you get home from work; a 150 pound person walking for 30 minutes at 3.5 mph burns 149 calories. The point is there are many different ways you can increase the number of calories you burn each day with very little extra effort.

3) Create a Calorie Deficit by Combining the Two

This option works the best for most of us – eating fewer calories and increasing our physical activity. By eating 250 fewer calories per day and burning 250 more per day through exercising, you have your 500 calories per day deficit. Maintain this deficit regimen for seven days and you will lose a pound. One-pound per week weight loss is both healthy and easy to maintain.
