Improve your metabolic rate with exercise, we’ll show you how. Resting Metabolic Rate (RMR) can be up to 60-75% of Total Energy Expenditure (TEE) during the day. Digestion and absorption of food is called the Thermogenic Effect of Feeding (TEF) and it makes 5-10% TEE. Energy consumed with exercise called is known as Thermogenic Effect of Activity (TEA) and its overall share of the TEE is 20-30%.
The main determinant of RMR is the Body Surface Area (BSA), which, however, may turn in your favor if you are in the game include diet and regular exercise. Restrictive diet with caloric intake may reduce the RMR. I’m sure you’ve heard that story, someone decides on a drastic diet seen in the latest editions of fashion magazines, and later returned to body weight at the turn of the old eating habits. Scientists have found that TEE is the most important value to which you must be careful when trying to balance an energy intake and expenditure.
Allow me to introduce you to the unwitting RMR-TV, which was and is still one of the main subjects of numerous research studies. RMR measured during a resting state, followed by a 12-hour fast which helps to control the effects of TEF and TEA-on RMR.
How diet and exercise affect metabolic rate?
McCargar conducted a study  in which he studied the effects of diet and exercise on metabolic rate in both sexes. Scientists Ballor and Poehlman conducted research with 46 people to determine how training and sex influence on body composition. Each of these studies lasted at least four weeks.
Effects of calorie restriction on body composition were measured caliper or hydrostatic techniques in each of the studies. It is important to emphasize that not all studies conducted and training program, as comparisons were carried out between the groups that had applied only to the new diet, and groups that have had besides eating and exercise vigorously pursued.
Changes are being read from the male and female subjects. Joint discovery for both sexes was the loss of lean body mass, which was significantly lower in the group with the included changing diet and exercise than diet-only group. For males is approximately 72% of the total body mass, fat loss seemed, while 28% went to the loss of lean body mass.
Female respondents have lost 76% of fat from the total body weight, and 24% of lean body mass. Discovery of this study was that it is possible to preserve lean body mass, with moderate resistance training three times a week at moderate intensity. This research was milled steady belief that women much harder to lose weight than men. Women can lose an average of 4% more adipose tissue and save 4% more lean body mass than men.
How does food intake affect RMR
To burn the energy we need energy so that there is scientific evidence to suggest that increasing the intake of food increases and RMR. This method was originally applied to patients suffering from anorexia, which were professional nutritional program increased RMR.
In fact, the increase in food intake increased the level of RMR to the extent that it is possible to surpass the increase in body weight. It is widely known and accepted fact that exercise increase metabolic rate. To be precise, rapid metabolism occurs during exercise and immediately after exercise.
One study was conducted and it revealed a statistically significant increase in RMR’s, over 18 individuals in mature and old age. The study included 10 men and 8 women on tests of riding a bike three days a week, in a cycle of eight weeks.
During the first week of the respondents had ridden the bike at 60% of their maximum oxygen consumption or up to 150 calories consumed. In the eighth week the respondents had ridden at 80% or up to 300 calories burned. Their body weight was not significantly changed or is it better to say that they are not gain or lose any lean muscle mass, as well as in adipose tissue.
However, dramatic improvement was noted in the volume of oxygen that goes into the body per minute. At the beginning of the volume of oxygen is 1.9 l / min, and the end of the study 2.1 l / min. During the cycling, RMR was increased by a full 11%.
Calorie consumption before the study amounted to 1.17 calories per minute, and at the end of 1.29 calories per minute. However, the reported rapid metabolism is not itself associated with only exercise, but also the flow of energy. Since respondents have not experienced any change in weight, additional food intake had to be consumed in order to compensate for the energy expended in the test on a bicycle.
This study has confirmed what has been revealed in a study with anorexics, nutritional factors may increase metabolic rate which in this case reflected on exercise endurance. As described earlier, an adequate nutritional intake that it is necessary to maintain the production of energy metabolism processes. What does this ultimately mean? If you want to lose weight, energy consumption must be replaced; otherwise there is a counter effect.
As we have already seen at the beginning of this article, a diet with an extreme low calorie intake (about 1000 calories a day) should be avoided, since it can reduce RMR and undo the beneficial effects of exercise that you have achieved. Recommended calorie intake falls between RMR and TEE, which is a caloric restriction of 15% to 20% for a healthy and gradual weight reduction.
Exercise should be part of the program for weight loss. Anaerobic activity of at least three times a week of moderate intensity is recommended and provides a significant advantage in preserving lean body mass and RMR’s. The total energy consumption (TEE) should play a major role in all the strategies of conservation of energy balance in a positive sense. TEF and TEA have a share of 40% in the TEE and the most susceptible to change. Highly intense exercise or training, have the greatest effect on TEE.
If used correctly in combination with a proper diet and neatly balanced energy consumption, even unattainable dream of a flat stomach and firm body could become a reality. Weight loss and increase of metabolic rate and maintaining lean body mass requires planning and commitment.
