Basal Metabolic Rate and Weight Loss Diet
Basic physiological functions necessary for survival, such as pumping blood, cellular repair, and internal
temperature regulation, require energy. The rate at which calories are consumed to create the energy needed for
these functions is the basal metabolic rate. This varies amongst individuals, but is typically 70 calories per
hour. A person’s basal metabolic rate is primarily determined by a combination of genetic and physiological
factors. The rate decreases slightly during sleep.
Regulation of internal body temperature has a significant impact on basal metabolic rate which increases about
seven percent for every half-degree rise in body temperature. When people are running a fever, their basal
metabolic rate increases.
Some medications can also have a significant impact on basal metabolic rate, which is why weight gain is a
common drug related side effect. Anti depressant medications tend to lower the rate and cause resulting weight
gain. When you are prescribed a medication, make sure to talk with your physician about its possible side effects,
and discuss your concerns about a particular medication’s potential to impact your diet and weight loss
It is not unusual for people to experience a temporary increase in their basal metabolic rate following an
injury. This happens to aid the body create new tissue and to repair and rebuild structures within the body that
were damaged as a result of the injury.
Dietary factors also impact basal metabolic rate. Consumption of an excessive quantity of high fat foods or
foods that are high in refined sugar can result in a decreased metabolic rate. Because these types of foods are low
in both fiber and bulk, they have a negative impact on basal metabolic rate. Consumption of foods that are not high
in fiber or bulk content slows down the rate at which the foods can move through the digestive system. Therefore,
the body absorbs more calories from these foods than from foods that are high in fiber and bulk before the foods
pass through the digestive system.
Additionally, proper nutrition plays an important role in regulating body mass index. Eating a well-balanced
diet that includes ingredients from all of the major food groups in moderate quantities is the best way to eat for
weight loss and maintenance, and also helps keep your basal metabolic rate functioning efficiently.
While most people concerned with weight loss and fitness tend to focus their attention of diet and exercise, it
is also beneficial to be aware of what basal metabolic rate is and how it may impact weight loss.
Diet and exercise only bring about weight loss when the number of calories a person burns off is higher than the
quantity of calories the person consumes. Basal metabolic rate is the determinant of the rate at which the body
So, when talking about reducing calorie consumption and increasing activity levels to bring about weight loss,
it only makes sense to include considerations associated with basal metabolic rate in the decision making
