Thermogenic thin? See how they act in the body (Brazil)
Some people attend gyms, play sports or run in parks during the week but, on reaching the end of the month in the balance the result is almost nil. So, ads appear miracle products that help burn more calories during exercise and lost several pounds in a short period of time: the thermogenic. The public relies on these substances, and are not miraculous, can bring serious risks to health.
"The friend arrives, says he took pills and lost weight so many pounds, then purchase and the other begins to take. But her friend Malhou like crazy, so lost and the other not," exemplified the endocrinologist Tertius Rock. According to him, the products sold thermogenic promises which can not meet, for example, elimination of fa
t. "The thermogenic increases the ability to shed calories and raises the temperature inside the body," defined the professional.
The problem begins when, while using the product, the result is not obtained. "Without exercise, thermogenic not help," said Rocha. Then one increases the dose and is subject to tachycardia, hypertension, stroke, mood changes, insomnia, anxiety, shortness of breath, liver problems and kidney complications in the lungs and heart failure, according to the endocrinologist.
The main substance is thermogenic ephedrine - banned in Brazil and the U.S. - according to the department chair of obesity of the Brazilian Society of Endocrinology and Metabolism, Rosana Radominski. In Brazil, the supplements are made from caffeine, she said. However, unlike ephedrine and amphetamine - which affects more aggressive - the body adapts easily to caffeine, so it ceases to increase caloric expenditure in the body.
Action in the body
The thermogeni
c increase body temperature and heartbeat, which gives more energy and willingness to perform physical activities. "The person becomes agitated," said Rosana. The blood circulates in higher speed occurs in the body and dilation of the veins. However, Rosana said that the amount of thermogenic substances in supplements is settled below the required weight loss.
"Ephedrine help you lose weight if ingested in high doses, but there are risks," she said. Thus, the effect of these products is like a placebo, said endocrinologist. The same applies to supplements based on L-Carnitine and Taurine - amino acids already produced by the body. "They also do not increase energy expenditure and not help with weight loss," said Rosana.
According to the trainer Bruno Franco, the thermogenic based on ephedrine and amphetamine have a more rapid effect, however, sold today made with licit substances, do not cut either end. "The levels of taurine and caffeine are low, so very little thermogenic increase caloric expenditure," he said. Increasing the dosage to compensate for the concentration of the substance is a high risk to health, it warned.
The thermogenic not addictive, because instead of "please" the brain, causing irritation, explained the endocrinologist. "One can only feel tired if you stop taking," she said. The professional said that "there is no drug without side effects." For her, one must consider the risks versus the benefits. In the case of thermogenic, "the loss of does not exceed 2kg everything to cause the substance in the body."
Healthy Weight Loss
A study conducted by U.S. colleges UCLA, Stanford and Harvard found that by passing an examination in saliva is possible to trace the exercises and diet ideal for a particular individual. Known as Pathway Fit, "the review is to analyze the genotype and shows the right path to better fitness," said Tertius Rock endocrinologist.
He said research shows that diet made based on the outcome of the Fit Pathway provides a weight loss 3.2 times more intense than ordinary (not based on genetic information). The analysis also indicates the years and the most appropriate according to rock, it is possible gain of 1.8 times more activity in certain muscles. In Brazil, the test is called the genomic landscape and is done in major laboratories in the country "The result is ready in 30 days and the person takes you to a nutritionist and a personal trainer," added the trader.
Although the thermogenic supplements are not recommended, coffee, guarana, white tea, cinnamon, ginger - all thermogenic - can be beneficial when consumed in balanced doses. The foods listed do not guarantee weight loss, but provide energy for exercise, according to endocrinologist Tertius Rock.
The tip of the personal trainer Bruno Franco is feeding at short intervals during the day. "When you go too long without eating, the body enters a stage of saving calories. If a person eats every two hours, the body releases more calories, because he knows that soon they will be restored," he said. The method helps speed up metabolism.
