burn calories (their metabolic rate) differently depending on a number of factors, including thyroid gland activity and other hormones.
Genetics is also a factor. Ever notice how body size typically transfers from mother to daughter?
Age - as we grow older, our metabolic rate slows at a rate of about 2% per decade.
Gender - males have a higher metabolic rate than females, due to their greater muscle mass.
Body Size - the heavier the person, the higher his/her metabolic rate tends to be since more energy is needed to maintain body processes. Likewise, a person who has greater muscle mass burns energy faster than his thinner counterpart. It's estimated that a pound of muscle burns around 3 times as many calories a day as a pound of fat!

In an article published in Medical News Today, author Christian Nordquist claimed:
"it is a common belief that slim people have a 'high metabolism' while overweight/obese people have a 'low metabolism'. However, underlying conditions, such as hypothyroidism (underactive thyroid) are not the most common causes of obesity.
Weight gain is mainly due to energy imbalance." Further, Mr. Nordquist asserted, "There is not much we can do to significantly change our basal metabolism - our metabolic rate when we are resting.
Long-term strategies, such as increasing muscle mass, will eventually have an effect. However, determining what your body's energy needs are, and then adapting your lifestyle according to that, will have a much faster effect on your bodyweight."View the article at http://www.medicalnewstoday.com
