Slow Metabolism and Overweight

A small percentage of people have slower metabolism due to an underactive thyroid gland. Thyroid gland is a double-lobed structure located in the neck that regulate the rate of metabolism. A blood test could diagnose the problem.

A lot of overweight people believe that their overweight body is the cause of slower metabolism rate. They think they burn up calories slower than slim people. This is not true. As a matter of fact, slim people have slower metabolism the overweight people. The most important factor that govern the metabolism rate is how big you are. The heavier a body is, the more work it has to do. Hence the more calorie it needs and the faster metabolic rate it has.

For example, a 70kg women needs much more to eat than a 50kg women in order to maintain weight. Once the 70kg women begins to lose weight, her metabolism rate will slow down gradually. If she slims down to 50kg, her metabolism rate will be similar to the 50kg women if other factor are equal.
