| Between
body weight and metabolism, a widespread misnomer runs amok.
Contrary to popular belief, being overweight is unnecessarily
correlated to a sluggish metabolism. The condition known as
hypothyroidism or an under-active thyroid gland is not always
associated with being overweight.
Quite
the opposite, excess weight is infrequently related to having
a low metabolism. Consequently, the vast majority of individuals
who are over weight are not afflicted with the condition of
an under-active thyroid gland. Nevertheless, a physician may
conduct a comprehensive evaluation to assess a medical condition
could be affecting anyone’s weight gain.
Generally,
weight gain transpires when there is an imbalance of energy
or expended fuel versus the consumption of excessive calories.
Losing weight necessitates raising the number of calories burnt
via physical activity, the creation of an energy deficit by
consuming fewer calories or ideally both.
A
Review on the Body’s Caloric Requirements
Four
elements affect calorie requirements: gender, age, body size
and composition.
-
Gender. In general, men have more lean muscle and less body
fat than their female counterparts do. As a result, it is the
primary reason men have a higher basal metabolic rate and are
able to expend more calories than women.
-
Body size and composition. In order of the body to function
at peak performance, a grand body mass needs more calories to
operate than a slighter body mass does. Moreover, muscle utilizes
calories faster than fat does. Consequently, more muscle is
associated with an elevated basal metabolic rate.
-
Age. With age, comes a reduction of lean muscle and fat percentages
increase. The metabolism becomes sluggish as the body ages,
naturally. In aging individuals coupled with their slowing metabolism,
the body’s caloric requirements are reduced.
