The basal metabolism or basic metabolic rate (BMR) is the minimum rate of energy expenditure per unit time in an endothermic animal at rest. (McNab, 1997). Metabolism refers to the processes where the body needs to function. Basal Metabolic Rate is the amount of energy expressed in calories where a man must burn or dispose of to keep his body alive at rest. Some of these processes is respiration, blood circulation, controlling body temperature, growth of cells, brain and nerve function and muscle contraction. The basal metabolic rate (BMR) affects the speed that a person burns calories and ultimately whether to keep or gain or lose weight.
The basal metabolism or basal metabolic rate (BMR), is the set of metabolic processes that manufacture and degradation of our body in a state of complete tranquility in the clock.
The 60-75% of the total daily energy expenditure given as basal metabolism. Therefore if we increase them should know who determine the factors and what does it depend?
The main modifiable factor that may epirestei basal metabolism.
People who have high levels of muscle mass, basal metabolism is increased.
So for a given weight (eg 70kila), the person who has higher levels of muscle mass basal metabolism will be more high, will seem weaker and losing more pounds efkola.I exercise is one that helps increase muscle mass.
Men have more muscle mass than women for this and the basal metabolism is higher and more easily lose weight.
However it is worth highlighting that this seemingly fast weight loss showing the scale does not last forever, and certainly not just fat loss.
For fat loss should the men to make an equally strong effort combining always balanced diet and exercise.
As we age the basal metabolism decreases.
It has been found that after age 30 and every ten basal metabolism is reduced by 5%.
And here is where the body composition because, among other things as we age reduces muscle mass and increased fat.
RESTRICTED ENERGY DIETS
The human body has the ability to adapt its energy expenditure according to energy intake.
A sudden and sharp decrease in calories will result in reduced and basal metabolism: when the body perceives that there is a lack of food then trying to make the economy and reduces the combustion.
For this reason, strict diets lead with mathematical precision in weight gain.
Instead basal metabolism is protected by a gradual reduction of calories. In short, the body does not perceive a significant change in food intake and thus does not reduce the combustion. So finally we manage the calories we take in are fewer than those we burn, resulting in weight loss.
Almost all diseases affecting the basal metabolism.
Indicatively, in hypothyroidism, polycystic ovarian syndrome, hypogonadism (ie. Reducing the fylou- hormones as done eg menopause) basal metabolism decreases.
However it should be noted that especially for hypothyroidism if successfully treated with proper treatment then you will not have a problem in your effort to reduce your body weight.
CAFFEINE – NICOTINE – CLIMATE
The basal metabolism increases with caffeine and nicotine and suppress a feeling of appetite.
The basal metabolism is increased by exposure to cold.
The basal metabolism seems to be influenced to a small extent by heredity.
The affects around 7%. So even if you believe that your basal metabolism is low because genes that does not mean you are doomed to be overweight.
You with the right help you achieve a healthy body weight.
To achieve a normal body weight should energy intake is less than that consumed.
In short not recommended to starve to lose kilos, but instead will just have to adjust food intake and exercise so that the calories we get from food is less than you burn through our daily activities.
Therefore erroneous metabolism perceptions should not prevent you from starting a serious attempt weight loss if you decide.
