Factors that influence metabolic rate

Metabolic rate and calorie requirements vary from person to person depending on factors like genetics, gender, age, body composition and amount of exercise. Health status and medical conditions may also influence metabolism.

One regulator of metabolism is the thyroid gland, at the front of the neck just below the Adam’s apple. The more thyroxin a thyroid gland produces, the higher a person’s basal metabolic rate will be.

Having a fever can also affect a person’s basal metabolic rate. For each increase of 0.5 degrees Celsius in a person’s internal body temperature, their basal metabolic rate increases by about 7%.

If you really want to give your metabolism a jolt, the easiest way is to bump up your muscle mass and activity level. By increasing muscle mass, you’ll also increase the base number of calories needed to maintain those muscles. Instead of complaining about a slow metabolism, you can try to turn it up to be a bit quicker.
