To try and also to try with all the effort of the planet to lose weight, but not to achieve it. Or you can lose just a few grams or kilograms, but recover them again, and with some extra vindictive ones. Does that ring a bell?
Lately, there has been some talk about a new theory that tries to prove why some people seem to be unable to lose weight despite insisting on diets and exercise. Louis Aronne, an obesity specialist at the Presbyterian Health Center in New York City, explains in an article in the Forbes Gazette that scientists are finally finding an answer to this"mystery.
And what have they discovered? The truth is that the answer is very surprising: years of eating - and overeating - the usual American diet actually generates changes in the brain. More particularly, it damages the signaling pathways in the hypothalamus, the part of the brain that regulates metabolism.
Aronne explains that patenting is very convincing: "Eating fattening foods causes inflamed cells to enter the hypothalamus. This creates an overload on the neurons, causing neurological damage. Cutting-edge research in the journal published in February 2003 published a study entitled"Relationships between dietary macronutrients and adult neurogenesis in the regulation of energy metabolism", which deals exactly with this theory of hypothalamic damage, thus opening the way to new strategies in weight loss.
A team of scientists at the University of Liverpool examined different types of weight-loss diets in their research. One of the results they extracted was that a diet high in supersaturated fats and simple carbohydrates sets in motion a chain reaction of the , that involves the regulation of hunger through the hormones leptin (reduces hunger) and ghrelin (increases it).
Another of the other results extracted proved that a diet high in fatty carbohydrates gave rise to alterations in structural plasticity, that is, changes in the brain. Over time, consuming too many simple calories (fat and sugars) over time damages the nerves that carry signals through the hypothalamus, affecting the function of leptin and ghrelin and, consequently, the body's ability to regulate weight and metabolism," Aronne says. In other words, the brain is out of control and can no longer be trusted with messages about hunger, appetite and satiety.
So, what's going on to lose weight?
Change your diet, and make it fast. It's about biology," says Aronne. Although some damage to the hypothalamus may be permanent, much of it can be reversed. If food with less fat is consumed, the cells that enter the hypothalamus are not inflamed, thus reducing the average damage. It does not matter whether you continue or not with a specific diet; it is enough to reduce your intake of calories, fat and simple carbohydrates.
There are many diets that can be done in any case. There's no reason not to try one and see if it goes even better. But remember always and in all circumstances to work with your body, not against it (referring to demanding and very restrictive diets). By being reasonable with the configuration of the diet and not subjecting our body to levels of suffering by reducing the amount of food or by moderating the amount of food products too much, we will achieve better results.
Another way to thrive and lose weight is to try to reverse the damage caused. Research at the University of Liverpool also found that omega-3 acids, known to be beneficial for brain health, have a positive impact on reversing the damage. Fish oil also seems to modulate certain negative effects of oversaturated fats and carbohydrates.
Indeed, this means that a change to a healthy diet can heal the hypothalamic damage that ravages the appetite and satiety of quite a few people. As Aronne publishes in his book (two thousand and ten), a healthy and healthy diet includes lean meat, lots of seafood, lots of fruit and vegetables, and unrefined grains. More information about Dr. Aronne and his views on brain signaling and weight loss is also available on the Weill Cornell Medical Institute Web site.
But the key to success lies in time. Permanent weight loss takes time. Many people who have lost weight after a successful diet have regained it after one or two years. Science suggests that the major drawback is that the brain's metabolic signaling system needs plenty of time to heal.
