Basal Metabolic Rate Explained

Basal metabolic rate (BMR) is the rate of energy expenditure that your body goes through the rest. In other words, the number of calories your body needs to survive if you are alone in bed.BMR is important in the equation for weight loss, accounting for 60-75% of total calories per day. The BMR is proportional to your lean body mass (muscle c.), And after 20 years, was reduced by about 2-3% per decade. In general, women tend to have a lower age all due to lower lean body mass BMR.In either case, the metabolic body weight decreases about 0.01 calories / min for every 1% increase in body fat. So, just need to have more fat in their body decreases your basal metabolic rate. Instead, do things that burn fat and promote muscle development increases metabolism.Check out this ...Despite calories / minute 0.01 variation may seem insignificant, this small difference can be much more meaningful if you fill gradually books. For example, a difference of 5% of the fat in the body weight is a difference of 0.05 cal / minute, which is equal to 72 calories / day. Since 3500
calories equals 1 kg of fat in our example, it would take 48 days to add an extra pound of fat (equal). This may not seem like much, but over a year it would be an extra seven pounds of fat only 5% of initial fat difference. But it is actually more than 7 pounds of your body fat gain as you continue to pack on the weight.Other influence basal metabolic rateLean body mass is not the only factor influencing BMR. In 1919, Dr. Benedict and his colleagues have shown that prolonged regimens was associated with a 20% decrease in BMR. These results were confirmed in the famous Minnesota starvation experiment where restrictedby caloric intake was 25% within 24 weeks. This study showed that per kg of body weight, basal metabolic rate is reduced to a system of semi-starvation. The researchers also showed that the activity of the nervous system T3 (a thyroid hormone) and nice also decreased.The last two results are quite important considering tha thyroid is the master gland that regulates the body's metabolism. A decreased inherent function make it harder to lose weight. I saw this practice of working with hundreds of men and women suffering from hypothyroidism, which at the same time, had a very difficult time losing weight.The sympathetic nervous system plays an essential role in the body's ability to mobilize and burn fat. Because it stimulates the release of adrenaline from the adrenal glands, a hormone that breaks down fat, without interruption of its operation also affect fat burning.That the data from these studies reveal semi-starvation, is that during periods of low caloric intake, reduces tissue energy production in an attempt to adjust to the lower calorie intake and reduce rates of weight loss. It is simply a survival mechanism. Obviously, this is a necessary adaptation in times of famine, but it is counter-productive if your goal is to lose weight fast and forever.However, your metabolic rate can bounceBMR is also sensitive to periods of overeating. In the experience of schemes Benedict et al. mentioned above, when subjects were given a day to "eat without" BMR was raised the next day. Moreover, in the long term (14-20 days) supercharger causes obesity, increase in TMB were recorded.This seems intuitive-cons. After all, if you increase your metabolism to help you lose weight? In most cases, yes, but not if you want to eat to the point of creating a dramatic positive influence energy balance.Essentially, during the dynamic phase of weight gain (to a level below the highest weight), more calories are needed per kg body weight to maintain that weight gain maintenance of a normal body weight. This is obvious and is also one of the reasons I feel more hungry when they are most active.Metabolism Exercise and adaptationsThere is no doubt that your metabolic rate is high year. The questions focus on how and how long is high, and to what extent it contributes to total daily energy expenditure.Studies have shown that learners have a higher metabolic rate than unskilled - but only when done high intensity workouts and consumed enough calories to maintain energy balance. This suggests that the higher metabolic rate in trained individuals is not due to chronic adaptations associated with training, but more to do with the acute energy flow associated with the last training and food choices.Therefore, we can say that, in the long term, daily exercise is necessary to maintain a high metabolism. However, we must not forget that what you do today, potentially, have a serious impact on your metabolism as your training combined in recent years efforts. One more reason to work at least every other day is essential to maintain a high metabolic rate and help you lose weight and stay slim!
