Stress and catch of weight

Stress and catch of weight

When a chronic stress settles, the glands suprarenals release from great quantities of cortisol, the hormone of the stress. A rise in the levels of the hormone of the stress can have as a consequence an excess of body greases. To control the stress could thus be a means of controlling the excess of weight.
Minor amounts of cortisol are beneficial but when its secretion is prolonged, the hormone of the stress can then have harmful effects on the good performance of the organization, on the systems cardiovascular, immunizing, neurological or metabolic.
Various ways of acting on the catch of weight
Cortisol acts in various ways on the catch of weight. Initially, it sends powerful signals to the brain which increase our appetite and our pangs of hunger for food which pleases or of food to us “consolation”, as sugar, greases or alcohol. The impact of the glucocorticoïdes as cortisol on the food catch passes partly by the neuropeptide Y, synthesized on the level of the hypothalamus and powerful stimulating food catch. This neuropeptide Y also acts on the production of insulin and the storage of greases of reserve. In the rat, the glucocorticoïdes support the ponderal catch induced by neuropeptide Y. Contrary, the leptine produced by greasy fabric act like factor of satiety on the level of the hypothalamus and have opposite effects with those of neuropeptide Y. But, always in the animal, the glucocorticoïdes are opposed to the protective effects of the leptine and support in fine the ponderal catch. Then, cortisol acts like a signal for our lubricating cells: he asks them to preserve more greases and to as release little of it as possible. He blocks also the action of many hormones like insulin, so that the control of blood sugar is disturbed and that the food pangs of hunger of comfort or consolation are multiplied by ten. The hormone of the stress can also interfere with serotonin, one of the chemical messengers of the mood of our brain, and lead to a feeling of depression and, once again, to even more food desires of consolation. Recent studies show that cortisol has an impact on neurotransmitters of the food catch. In the rat, a central infusion with dexaméthasone stimulates the catch food and led to a ponderal catch. This effect, associated with the secondary hyperinsulinemy and the insulinorésistance, stimulates the lipogenesis and the accumulation of greases. In addition, the hormone of the stress interferes with the growth hormone with for results a muscular loss and a fatty weight saving. Lastly, a continual rise in the hormone of the stress can weaken the operation of thyroid and make so that our metabolism slows down. All these combined effects make that our organization consumes more calories and burns some less and less. We thus take weight and more specifically around the size and belly, which increases our risk of hypertension, diabetes and cardiovascular diseases. Studies on the stress, the food and cortisol noted that the women with an overweight in the abdominal area produced more cortisol when they were stressed that those whose weight was distributed differently. In addition, the women having cortisol elevated levels caused by the stress tended to eat more in stressing situations (September/October 2000 exit off Psychosomatic Medicine). The researchers also noted that diseases caused by cortisol elevated levels, like the syndrome of Cushing, are characterized by excessive quantities of greases in the abdominal area, an unhealthy distribution which increases the risk of hypertension, cardiovascular diseases or diabetes. The stress, via its hormone, can thus make eat more and increase the storage of greases. That can mean that to control the stress could help to control the weight.
To decrease the impact of the stress
To practise a physical exercise regularly and to sleep sufficiently belong to the key elements to fight against the stress and contribute to decrease the cortisol levels. To avoid alcohol and sugar excesses, to decrease the cafeine consumption to the nonstimulative herb tea profit also take part in it. A study published (July/August 1998 exit off Psychosomatic Medicine) watch which cafeine can raise the levels of cortisol and ACTH, another hormone of the stress. Relora® decreases the symptoms associated with the stress
Relora® is a patented mixture of extracts of Magniolia officinalis and Phellodendron amurense. It contains components which act on the anxiety but without the side effects of many drugs nor causing somnolence. The extracts of the mixture brought by Relora® are complementary one the other to constitute a antianxiété agent more complete than would be to it each one of them. Its releasing effect can thus help to control the appetite and to prevent the pangs of hunger related to the stress, thus helping to control the weight. A study published in 2001 in Psychopharmacology shows that Relora® has a nonsedative activity, anxiolytic in some eight days old chicks after a stressing process of separation. The study concluded that Relora® could be useful to modulate states of anxiety. Fifty subjects were covered, with the Living room To skirt Clinic of Cincinnati to the United States, during two weeks with 200 Mg of Relora® three times per day. The results showed an effect releasing at 78% of the subjects. Although Relora® does not produce a sedative effect, 74% of the subjects gave a report on a resting sleep. 8 people out of 10 felt released better. 24% of the subjects brought back a somnolence. A second test was undertaken in the same establishment to measure the levels of cortisol and DHEA among 12 moderately stressed patients. Elevated levels of cortisol and depressed DHEA are associated with a chronic stress. Two weeks of supplementation with of Relora® involved a significant growth of the salivary DHEA (227%) and a reduction in the salivary cortisol levels (37%). During the treatment with Relora®, the levels of DHEA and cortisol returned to the normal at all the subjects. A third bearing test on 49 subjects obtained results similar to those of the first concerning relieving and the resting sleep. Moreover, the supplementation with Relora® reduced by 76% the snacking of sugar refineries caused by the stress at the subjects having stated to eat this type of food under the influence of the stress. A fourth test, a clinical trial as a double blind man, controlled against placebo, was finished in January 2004. The objective of this study was to determine the effect of Relora® on women in overweights which, usually, ate more when they were subjected to stressing situations. In the group under placebo, a significant catch of weight was observed and a light loss in the supplemented group. The researchers of Miami Research who made a study from it concluded that subjects in overweight eating in answer to the stress could draw a beneficial effect of the catch from Relora®. The mechanism of action seems to pass by a reduction or a standardization of the levels of the hormone of the stress. The rhodiola babbit metal insulin levels
The rhodiola (Rhodiola rosea) was used in Soviet Union as adaptogene. One allots the capacity to reinforce to him the nervous system, to fight the depression, to improve immunity, to increase the capacity to practise a physical exercise, to improve memorizing and the energy levels and to perhaps prolong the life expectancy. Studies on animals suggest that the extract of rhodiola could help to standardize the blood sugar levels and to decrease those of glucagon. This effect is based on its properties adaptogenes, including actions on the suprarenals likely to help to control the insulin levels. Work on animals also indicated that an extract of rhodiola can prevent the increase in beta-endorphins generated by the stress.


The phosphatidylsérine module cortisol levels
The phosphatidylsérine is a phospholipide which one finds in quantities concentrated in the cells of the brain. It is supposed that she plays of the roles structural and metabolic for the muscular metabolism and operation of the immune system. Scientists think that in the long run, it would have the capacity to modulate the cortisol levels and that it is not possible to realize it short-term. A study examined the effect of the phosphatidylsérine on the reactivity of the glands suprarenals (ACTH and cortisol) and on the psychological answer to a mental and emotional stress. 20 subjects were covered during three weeks with phosphatidylsérine or a placebo. The results showed that the supplementation led to one émoussement marked of the answers of cortisol and the serum ACTH as well as salivary cortisol, suggesting that it could be a potential treatment of the disorders related to the stress. The releasing effect of L-théanine
L-théanine is an amino-acid which one meets in the green the It supports a feeling of relieving and wellbeing without interfering with the cognitive capacities. It allows thus, at people subjected to an important stress, to increase the concentration and the determination. Although not causing somnolence, L-théanine improves quality of the sleep. The ashwagandha against the harmful effects of an acute stress
The ashwagandha is called the Indian ginseng and is used in the situations of stress and, more particularly, in the event of insomnia, of nervousness or instability. Its properties adaptogenes are allotted partly for its purposes on the production of the hormones suprarenals. When the ashawagandha is managed with animals, it against many biological changes accompanying the acute stress, including modifications on blood sugar, the weight of the suprarenals or the levels of cortisol. The withanolides that one finds in the ashwagandha are substances with a structure of sterol supposed to be responsible for its properties adaptogenes and of which the effect is similar to that of glucostéroïdes.
