Speed up metabolism with muscles?

Having often documented a lot on diet, nutrition, proper nutrition and related topics, such as fitness, particular foods, tricks to lose weight, etc., I often come across sites of personal trainers or similar, which say they can turn the body into a machine fat burner , and make your metabolism speed up thanks to a more toned, more muscular and more responsive body. But is this really the case or are they just selling us something, starting with their beliefs? In particular , have you ever wondered how much you can speed up your metabolism by building a muscular body ? Here, I have often wondered, until I arrived here, in this article on Askmen.com which explains that there are no tricks to speed up the metabolism .
The article was written by James Fell , a fitness specialist, book author, subject matter expert for various publications. He says that with regard to our basal metabolism, or the energy we spend even when we are at rest, having a muscular body does nothing : clearly, to speed up the metabolism it would be enough to lead a more active life , but if we think that there is a trick to keep it high all the time, even when we don’t do anything, well, Fell says we’re making a hole in the water

In fact, all the efforts we make to lose weight slow down the metabolism because they are aimed at weight loss: the healthiest diet, the most active life, etc. Of course, not in the short term. In the short terma reduction in calories, the choice of healthier foods and kicking a little more make us lose weight because the body is used to burning a certain amount and therefore will respond by continuing to burn. But then he adapts and the game is over. Meanwhile we have lost weight, perhaps, and a leaner body corresponds to a lower metabolism . At that point, it stalled, and often researched on the internet to solve the problem.
Fell illustrates at this point the hoaxes that run on the web and that promise to speed up the metabolism.
The first hoax is that of the title of my article, that is, that we can accelerate the basal metabolism with a more toned and muscular body: muscles burn three times more than fat, it is a pity that our basal metabolism only works from 20 to 25% thanks to our body structure. 75 percent, on the other hand, is how much the body burns to maintain the functions of vital organs: heart, lungs, kidneys, etc. So we’re talking about increasing this 25 percent of our basal metabolic rate, perhaps, to burn more even at rest. How much will it be in caloric terms? One hundred, two hundred calories? According to Fell, who did the math for himself, from being overweight (20 pounds of fat) to now having the body of an athlete (ten pounds of muscle),in his case it is about twenty calories of extra energy expenditure as regards his basal metabolism . Of course, if you have the body of a marathon runner and were previously thin, your basal metabolic rate will burn perhaps one hundred more calories than before, if you have the body of a bodybuilder and were thin before, three hundred. But if you start from an initial obesity, your basal metabolic rate doesn’t change much with ten pounds of muscle as in Fell’s case, bearing in mind weight loss.
In short, it is how much you actively do to make yourself lose weight, not how much you spend at rest . In short, you can act on the total metabolism, not on the baseline. So, now that we know, do we say goodbye to the idea of muscles? No. But we don’t have to build muscle to burn more calories at rest, as for having a more toned body, less fat, more responsive and more active, a body that “responds better”, in short. A more active life allows us to burn more calories and eat more (but always with a view to a healthy diet).
