Every year millions of packages are lost during shipments. So there are companies that are selling them to weight

by

Only in the United States They lose or steal 1.7 million packages every day. In Spain the latest data from the TDI logistics group They revealed that more than two shipments were lost per minute. The curious thing is where at least part of them end: they are shown to weight. Millions of lost packages. According to They indicate to EFE From the employer of the logistics sector one, in Spain more than 3.3 million packages are sent per day, and the cases of loss involve a tiny fraction of 0.001% (about 3,300 per day). A simple error on the label or lack of centralized information can cause these problems, and that is where some companies recover them to resell them. Reversing weight. Services such as Crazy Day Factory, My Mystery Package, Merkandi, LotesDevolutions, or King Colis are dedicated exactly to the same thing: acquiring those lost packages to often resell them as part of surprise boxes that are sold to weight. As they point out in the confidentialin Kink Colis for example they establish a price of 1.99 euros per 100 grams in standard packages and 2.79 euros in the premium type. A lot of noise and few chollos? In King Colis FAQ, a French startup, they explain that buying this type of surprise packages can be very profitable, because one “can contradate state -of -the -art technological devices to clothing or accessories of recognized brands.” However, they also warn: “Not all lost packages necessarily contain treasures. There is a part of chance!” You don’t know what you buy. One acquires these packages to weight, but does not really know what he is buying. As they revealed in the nationalin stores such as my mystery package open ephemeral stores throughout the year in different municipalities to give out these packages, but there is a key requirement: the package cannot be opened until after buying it. And that implies risks. These lost packages are not checked and therefore can be damaged, be defective or have a much lower price than the buyer ends up. In Lotes Devolutions they explain that those products that put on sale – which are returns, not lost shipments – do not go through a previous check, which can end up causing a disappointing surprise effect. Packages are sold repaired without visible brands to eliminate commercial references, turning the purchase into a riddle … or a bet. The psychology of surprise. The surprise boxes such as those offered by all these businesses take advantage of known phenomena of human psychology. Several researchers published in June 2024 A study in which they revealed how the stimulus-organism-response (Sor) causes that impulsive purchase out of curiosity without intervening conscious thinking. We think quickly instead of thinking fast, as the Nobel Prize Daniel Kahneman in his famous’ stood out in depth.Think quickly, think slowly‘. Previous experience. In Xataka we were able to meet this type of business last year, when we went to an old warehouse on the outskirts of Madrid to try to locate some cholt between the chaos of Amazon returned products that a company put on sale. There was no surprise effect here and the proposal is something different, but the conclusion was already clear: we had no luck and after hours of search we went out empty. Finding chollos, whether by surprise or not, is not easy. Image | Chuttersnap In Xataka | The end of free online returns: Zara, Pull and Bear and more stores begin to collect them

If “Fast Walk” serves for yourself to lose weight

by

Is it possible to lose weight walking? It is a recurring question and is logical. After all, physical activity facilitates the consumption of calories that our body stores as fat. But it also turns out to be a form of Exercise available to almost everyonesomething important if we take into account that constancy is usually key when we talk about thinning. However, the answer to this question is somewhat more complex than it might seem. Yeah, walk It is a good way to burn calories, and much more: it is also an exercise that provides benefits to our cardiorespiratory and muscular health, and also helps prevent the appearance of diabetes, among other varied effects. That is why it is usually remembered from time to time that, although walking it can be very useful, it may not be the exercise that best suits our plans, and could be seen more as a complement that as the main resource to which we stick to. Now, let’s investigate why. As experts remember, exercise is not always the best strategy if what we are looking for is to reduce our body mass. “For weight loss, The diet seems to be more effective that physical activity “ Donald Hensrud explainsof the Healthy Life program of the Mayo Clinic. Rather, it is usually considered that, in general, the exercise is more effective when maintaining the weight; While if we want to lose weight, control our diet is usually considered a more effective strategy. Of course this does not mean that we should forget this part, even if only for The positive impact That an active life has in our health. The problem is that we tend to Overbear the impact of exercise and physical activity in general in the caloric consumption that our body performs. Alternatively, we can express it in a different way: we tend to underestimate (or directly to ignore) the enormous caloric consumption that our body performs only by being, to keep ourselves alive throughout our day to day. Some estimates place the relative weight of physical exercise Between 10% and 30% of caloric consumption. Imagine a situation in which physical exercise represents 20% of the calorie expenditure that our body performs. This implies that if we folded the exercise we do (100% more activity), we would only increase the caloric consumption of our body by 20%. Combine strategies Leaving weight loss in the hands of a simple strategy is not usually recommended. Constancy is important and use the Exercise as a complement To the diet when we want to lose weight, it can be helpful in various ways. First and perhaps more important, for being a healthy habit to incorporate in our day to day. Secondly, exercise can make changes in the diet more, “distributing” the effort we put to change towards healthier habits. Since constancy is important, a small help never hurts. Third, the exercise, we pointed out before, is a good way to keep us in our weight. The sooner we get the habit, the better. Walking can help us with these three purposes, so it is a perfect complement if we want to lose weight and want to do it in a healthier way. It is a good complement but is it the best? Walking has the advantage of helping us build Routines without great efforts and minimizing the risk of abandonment; But if what we want is to increase the caloric consumption of our body, for example to be able to resort to less strict diets, there are alternatives that perhaps better adapt to our needs. Finally, it is never worth remembering that each body is different, even our own body changes over the years. Formulas and weight losing recipes are not universal, so it is always useful (when not absolutely necessary) consult with experts who can guide us in the process.

There are those who are adding fungi such as cordyceps to coffee to lose weight. Science has many reservations

by

Coffee is a food, with numerous positive effects on our body. We get more and more about this Positive coffee actionbut we have determined to improve it adding supplements as proteins either Spirulina. One of the latest trends? Enrich coffee with fungi. So that? To lose weight. And here the evidence is not so clear that this trend of ‘Mushroom Coffee’ is so healthy that invites a coffee with cordyceps to drink. The promise. Eating mushrooms or fungi has nothing weird, but a few years ago we began to see how the food industry It began to add them to other foods to create improved versions of them. One of the first brands that added fungi to the cocoa or coffee was FOUR SIGMICan American company that creates “functional foods” and well -being supplements. That is, coffee is not only coffee: it has a series of additions vegetables to relieve these, support the immune system or accelerate weight loss. The latter is what a more recent grabs Trend in networks like Tiktokthe baptized as ‘Mushroom Coffee’. There are several brands that sell coffee with fungi Cordyceps coffee. The defenders claim that coffee (and other foods) can be enhanced with medicinal fungi whose compounds carry a series of positive effects. Among those fungi are Reishithe León hairhe Maitake or the Shiitake (great in broths)but also the most famous cordyceps. Yes, that parasitic fungus that makes Some ants become ‘zombies‘And what is protagonist of the Apocalypse of ‘The Last of Us’. These fungi can increase energy production and improve metabolic function, helping in the burning of fats. They can also help control hunger, stabilize glucose levels and have Probiotic properties that favor both digestion and nutrient absorption. Market. And it is not a bizarre or the US thing: you can Buy coffee With cordyceps In Amazon If you want the healthy effects of coffee more, Chow they announcegreater energy and improvement in your mental clarity. There are different estimates, but this coffee market is expected to grow at a rate of between 5.4% and 5.7% during the next decade. There are studies that place their value at 1,203.4 million dollars in 2023 with a growth up to 1,833.4 million by 2031. They are considerable figures, but we compare, the estimate of specialty coffee is 62,500 million by 2032 and that of the entire market It will be of 632,000 million for that year. But well, it seems that this trend, little by little, is consolidated and grows. The small print. The logic here seems simple. In the case of protein: if it is a good supplement and coffee is a good food, mixing them works. With fungi and coffee the same thing happens, but something that should not be overlooked: there is a lack of research. The relationship between coffee and weight loss is well documented, being a good stimulating before performing some training and selling the caffeine as supplement. But, although the properties of these fungi are also documented, evidence on coffee with fungi and its action in weight loss or mental well -being is limited. Clinical trials are missing that confirm its direct effectiveness to lose weight and most of those available studies are in animals. Also, as we read in VogueNutritionist Marta Marcè comments that it is not usually specified whether the extract is from the fruiting body (rich in properties) or the roots (less powerful), in addition to using very low doses. And sometimes It is not even the real fungus. Dangers. Although cordyceps has a bad reputation due to fiction products in which it has been the protagonist and its effect on some insectsusually has no health hazards. Cordyceps coffee is approved by the USDA -The United States Department of Agriculture-, but you have to take some things into account. It may produce some allergies in certain people and it is necessary Influence when combining it With other stimulating products or drugs, but most importantly, above all, it is to know where those fungi that supplement chocolate or cocoa. Marketing, already such Because here the danger is how that fungus has been manipulated and the example we have had in Colombia, where a health alert on cordyceps supplements not regulated or fraudulent. And if you dare to try it, be from reliable and out of curiosity, not so much for its numerous promises, that millions move in the other part of the world.

Losing weight without losing muscle is the great challenge of drugs such as Ozempic. A protein keeps the key to face it

by

It is usual for us to often get news about hopeful scientific advances made in mice. These experiments always leave a question in the air, if the discovery can be applicable to humans. This does not always happen, but sometimes MITCH Silence the expression of a simple protein in our muscles can lead to weight loss and, more, more, It can allow us to lose weight Without putting our muscle mass at risk. The protein in question is called Mtch2 (Mithochondrial Carrier Homolog 2), but has been nicknamed “Mitch” by those who study the compound and its effects. The last analysis of this protein and its associated gene has observed that its “erased” in human cells causes in these lower efficiency Energy What is perhaps more important, this silenced causes cells to stop using carbohydrates as a priority energy source and in place they preferably use body fat. Different fuels. The cells of our body need energy and billions of years of evolution have given rise to a series of biological mechanisms that allow us to maintain a calorie reserve that allow us to feed these cells in times of greater shortage. These mechanisms imply that our cells can resort to different fuels according to the situation. While the carbohydrates we consume and the fats that we use as a reserve are the main fuel Ozempic. From mitones to mitochondria. According to Explain the responsible teamthe new study has its bases in a previous experiment conducted with mice that observed in the rodents an “improvement” in their body composition in the form of “protection” against obesity and the development of more muscle fibers. This accompanied by greater consumption of greater oxygen consumption and an increase in resistance. The results were promising but left the team with a doubt, if it would be possible to “inoculate” the body against obesity by silencing the expression of a protein without this negatively affecting muscle mass. To look for an answer, the team went on to focus on the role of the mitochondría, the organelle in charge of providing energy to the cell. The key is in the fact that the “mitch” protein plays an important role in the merger of the mitochondria, a fusion capable of increasing the efficiency of these organelles. By silencing protein, organelles would lose the ability to resort to this fusion which also implies less efficiency and thereby a greater need to consume energy resources of our body. It only remained to prove if this was also true in human cells. Less efficiency, more consumption. They thus verified that by silencing the protein in human cells, the “mitochondrial network” was undone and, as expected, energy efficiency fell. This left the cell in a “permanent state of energy deprivation.” And what is more, the team also found that this led to the cells to prioritize the use of fats as a primary energy source, instead of other possible sources such as carbohydrates. “After erasing Mitch, we examined, every few hours, the effect that it had in more than 100 substances that take part in the metabolism of human cells,” pointed in a press release Sabita Chourasia, co -author of the study. “We saw an increase in breathing, the process in which the cell produces energy from nutrients, such as carbohydrates and fats. This explains the increase in muscle resistance of previous experiments in mice.” The details of the study were published In an article In the magazine Journal embo. An intermediate step. The study takes an important step in the long process between the first results in animal models and the design of a treatment for weight loss based on what was learned. In following studies, the team intends to elucidate new aspects about Mitch’s role in the accumulation of fat in the body. The fact that women usually have higher levels of this protein can help researchers discover if Mitch is also responsible for the differentiation of fatty cells.

Obssing with losing weight is a very bad idea to lose weight. Luckily, science has many more effective

by

A young doctor appears before his boss and, although he does not say it out loud, he thinks “the last time I was in front of him, I swept at least a liter. But now I’m going to sweat at least ten, that guy will find out what is to sweat!” Then, do not sweat a drop. It is not fiction, it is A real case collected by psychiatrist Viktor Frankl In 1994. He did to explain that many times our fears, objectives and intentions play against us. And yes, we are talking about losing weight. Against us? It’s as if, for using A metaphor of another psychologists (Steven C. Hayes)“We fell into a deep hole and the only thing we had to go out was with a shovel. As we don’t know very well what to do and we despair, we started using the shovel.” The result, despite working day and night, is that we are deeper than before. What in the background tells us a good number of psychologists (from Logotherapists to Specialists in acceptance and commitment) is that we are so culturally attached to certain behavioral strategies that, although they are not useful, we cannot get rid of them. The obsession with “losing weight” is a problem. And yes, obsession is the word. In Spain, where 52% of the adult population presents overweight or obesity, seven out of ten people (72%) They have tried to lose weight at least once in their life. In fact, According to the Mapfre Foundation datathey have done it, on average, about seven times. That leads to “53% of Spaniards has ever followed a popular or miracle diet with the aim of losing weight.” It is not an accident; It is the consequence of what I commented: in the popular imaginary, the way of losing weight is that. That is to say, In words Giuseppe Russolillopresident of the Spanish Academy of Nutrition and Dietetics, “the population is not fully aware that the methods that use weight losing are extremes and can put their health at risk and that the recovery of the lost weight is frequent.” And what can we do? The first is to banish false myths. Sï, obesity is a health problem; but Not so clear that overweight is in general terms. “The life expectancy of people overweight is not less than that of Normopeso”, He told us Juan Ramón BarradaProfessor at the University of Zaragoza. Many ideas that we have above all this and that we use to justify our behaviors, are still disciplinary stories. That does not mean that health is not important. It means that many of those ideas about overweight, health and beauty are cultural strategies equivalent to getting to cabin being inside a well. So? There are no scientific knowledge that can help us? “From what we can extract from current investigations, there are three tips that can be given to anyone: Eat healthyexercise and Accept your body. Today, everything is reduced to weight loss, “he continued Barrada. Therefore, “we must be clear that stigmatizing people overweight or obesity such as ‘vague’ or ‘lack of will’ is to promote suffering” unjustified. And do it with ourselves too. Luckily, as Barrada pointed out, there is another way of doing things. Image | I Yunmai In Xataka | The scientific reason why miracle diets do not work is

Reducing weight loss carbohydrates seemed a perfect plan. We have just discovered that it comes with unforeseen risks

by

Carbohydrates or carbohydrates are a fundamental macronutrient in our diet. They represent, together with the fats, the main energy contribution to our body. Carbohydrates are also protagonists in some diets destined for weight loss, diets based on the fact that, in the absence of these nutrients, our body will resort to the energy stored in their fatty tissue. A plan that is not infallible. DNA damage. A new study has found a mechanism that could link low carbohydrate diets with a Risk increase of suffering from colorectal cancer. The union link would be in the microorganisms that reside in our digestive system, our intestinal microbiome. In a study conducted with mice, the team responsible for the analysis observed that these types of diets could worsen the deterioration of DNA caused by some of the microbes that usually inhabit our digestive tract. This facilitates the appearance of polyps that in turn increase the risk of appearance of this type of tumors. “Colorectal cancer has always been seen as the consequence of a number of diverse factors, including diet, intestinal microbioma, environment and genetic,” explained in a press release Alberto Martin, co -author of the study. “Our question was, does the diet affect the ability of specific bacteria to cause cancer?” Three diets under study. In his study, the team tested three types of diet: a “normal”, a carbohydrates, and a “western” rich in fat and sugar. He did it by combining these diets with different types of usual bacteria between our intestinal microbiota and suspects of keeping some kind of relationship with the risk of colorectal cancer. They found a combination of diet and microorganism with potential to trigger adverse relationships, that of the low carbohydrate diet and a variety of bacteria of the species Escherichia coli (E. coli). They observed that this diet encouraged production by the bacterium of the colibactin, a compound with the ability to damage the DNA and with it of producing cancer. The key I could be in the fiberthe team points out. This type of diets facilitates inflammation, altering the microbial community of its interior, which in turn creates an ideal environment for the propagation of the E. coli. A fallen barrier. The team also observed that the mucous barrier that separates epithelia cells (the outermost cells of the intestine) of bacteria was reduced, which could also facilitate that colibactin reaches intestine cells. This would increase the harmful potential of the compound. The details of the study have been published In an article In the magazine Nature Microbiology. And what about humans? Studies with mice have an obvious limitation, and it is that extrapolating what is observed in these rodents to our own species is not always possible. The team He stood out for it The need to confirm their findings in people, although they were also optimistic about the possibility that their study could be applied in cancer prevention. The microbioma in the spotlight. This is not the only recent study that has put in the spotlight to the bacteria of the species E. coli already the colibactin in regards to colorectal cancer. A few days ago We had the news of A study Made with patients from 11 countries who found exposure tests at an early age to this toxin could be linked to an increased risk of these types of tumors.

Ozempic has made thousands of people lose weight brutally. Then they have put their closet funds for sale

by

Novo Nordisk, the Ozempic manufacturer, has just presented the results of the first quarter and the data are impressive: we talk about 3,891 million euros, 14% more than last year. And, of course, that He has shot the price of the company. The most interesting, however, is why. And the answer is very simple: the treatments against obesity have risen 67%. It is what allows us to intuit that the Ozempic revolution (and the rest of the GLP-1 agonists go far beyond what we might think. So much so that he is putting up legs The second -hand market. Something is changing. In mid -2024, second -hand sales platforms began to see how the clothes offered in their systems changed. In the previous two years, large -scale women’s clothing ads had grown surprisingly: “A 103% increase in 3xl size ads, 80% in 4xl size and 73% in 5xl size”. Not only that, Poshmark analyzed the ads and discovered “a 78% increase in the new ads that mention ‘weight loss’ in the title or description.” Dressed Collective, specialized in second -hand sale of high quality products, has also detected a similar phenomenon and Goodwillfinds, which reverts donated clothing, says they are increasingly donated. Vinted He has also noticed. How do we know that all this has to do with Ozempic? We can’t be sure, it’s true. But, as they point out in Fortune, one in eight Americans already USA SEMAGLUTIDA OR ANOTHER GLP-1 agonist and the trend has been growing very closely to how the use of these medications grew. And, whatever it is, it is an issue that everyone begins to intuit that is serious. In fact, there are more and more resale programs of the brands themselves. Given these market changes, brands such as Levi’s, Patagonia and Carhartt Wip have begun to mount their own stores that allow them to also be present in this “second life” of their products. After all, As they point out in Vogue Business“The resale has been one of the only retail trade engines in recent years.” In fact, the market has been bent since 2021. However, not all the mountain is oregano. The problem is evident: as thousands of people lose weight significantly and They decide to purge their cabinetsthe stocks of second -hand stores are unbalanced: there is a lot of big clothes to sell and few people who want to buy it. That is, if analysts are right, we are going to A great readjustment of the fashion we produce, sell and buy. In a world pregnant with data and more data, it may seem curious that the first to realize have been Second -hand platformsbut little by that we think it is so predictable that it scares.

More and more people take a “pacifier” of vinegar or herbs early to lose weight

by

Until recently – and some video may still appear Scrolleando In Tiktok – they marked trend the Morning Shedswhere people recorded showing step by step how their day began. Between cafes, cold showers and positive statements, somewhat more questionable practices were also sneaking. But the curious thing is not only what they did, but what has remained: now, many of these videos focus solely on what they take in the morning. A morning habit. In social networks, especially in Tiktok, the morning chupitos have taken prominence. What started as A punctual gesture between celebrities “Such as the chest of wheat grass,” it has become a viral phenomenon that floods the feeds of hundreds of users. From ginger chupitos to herbal combined, the concept is always the same: a quick dose that promises great results. But beyond the format, the question arises from whether the idea that a simple drink can be the key to thinning and detoxifying the body is really transmitted. There is one that stands out. Among all these drinks, apple vinegar has won a special prominence. In the videos we can see how Drink apple vinegar pacifier Easy under the pretext that it will help them flatten the belly and burn fat. Yes, it is true that some studies They have observed That consumption of this type of vinegar can slightly reduce blood glucose levels and total cholesterol. Now some specialists They have warned on the possible adverse effects of its excess consumption and on an empty stomach ranging from the irritation of the stomach or the esophagus to the damage to the dental enamel. There is even more. This trend of Shots morning is not limited to apple vinegar, there are also infusions of Tik Tok or ginger and turmeric chupitos that have entered the category of natural remedies presented as rapid solutions to detoxify the body or accelerate metabolism. “I’m going to show you this Tik Tok recipe,” A user comments While preparing a tea with ingredients that, according to what you have seen, can help lose weight. However, some experts They have pointed out That many of these combinations do not have sufficient scientific support and can have adverse effects. For example, excessive green tea consumption It can interfere In iron absorption. Behind the investigations. Despite the rise of morning chupitos on social networks, specialists They have coincided that there are no conclusive evidence that supports the alleged detox or slimming benefits. The available evidence is limited and, in many cases, the observed effects are minimal or circumstantial. More than resorting to fast solutions, experts They have insisted in prioritizing a balanced and sustainable long -term diet. A healthy intestine. For a while now, hashtags like #gutok and #guthealth They have popularized Jengibre chupitos, turmeric supplements and probiotics that, supposedly, help eliminate swelling and improve intestinal health. However, what really needs intestinal microbiome is dietary fiber from cereals, whole grains, fruits and vegetables, such as He explained for The Guardian Dr. Saman Khalesi. Along the same lines, natural infusions such as green tea or chamomile have been viralized, associated with anti -inflammatory and digestive properties. The culture of immediacy. We live in an era where everything seems to be fast, from purchases to the results. In that sense, it is not surprising that the morning chupitos have captured the attention of many users on social networks. The promise of rapid and visible results appeals to those who seek immediate changes in their health, but specialists insist that it is important to contextualize these practices. To what extent are these morning gestures provide real benefits or only perpetuate the illusion of express solutions? Image | Pxhere and Pexels Xataka | We take more and more mercury through fish.

Summer is approaching and with him the new obsessive trend to lose weight quickly: the patches to lose weight

by

There are nine weeks left for summer and social networks have not taken to remember it. This year, the trend is a clear two -way revival that He has flooded everything: Not only outfits with y2k hats or minimal tops, but also thin body. Quite back the discourse of bodily positivity has remained, and the obsession with weight loss has returned strongly. This time, in the form of stickers. Slimming patches. These products, marketed under names as Weightless either Diet patchThey are transdermal adhesives that are placed on the skin on the wrist or belly. The Reels In social networks and manufacturers ensure that they help lose weight, reduce appetite or accelerate metabolism. The promise is simple: pégate it and lose weight, with no more effort than to remember every so often. Some even present with slogans such as “needleless version” of medicines such as Ozempicdespite having absolutely nothing in common beyond marketing. Does it really work? According to a Bloomberg articlethe theory behind these patches is that they release “natural” ingredients to the body through the skin. Some include compounds such as berberine, green tea extract, caffeine or bullfighting. However, there is no serious scientific evidence that supports these compounds that can be absorbed by the skin in significant amounts to reduce weight. As They have detailed In Medical News Today, some experts have agreed that these products are sold as supplements without strict regulation and it is practically impossible to know what they really contain. As He explained Professor Nerys Astbury of the University of Oxford in Bloomberg, although some medications are administered transdermally (such as nicotine or contraceptives), it has not been shown that appetite suppressors can do it effectively. Boom to lose weight. This whole situation occurs in a context in which obesity medications are more fashionable than ever. Products like Ozempic, Wegovy either Zepboundbased on the GLP-1 molecule, they have been revolutionaries in the treatment of overweight. Unlike viral patches, these do have clinical studies, medical approval and proven results. But of course, they require recipe, medical monitoring and, above all, a puncture. Hence the idea of ​​a “LPG-1 in patch” sounds so tempting. A background problem. What really is at stake is not only the patches, but what they represent. There are many videos about “losing weight” with increasingly crazy routines and, now, it has touched the turn of Loss to lose weight stickers. These types of rapid solutions perpetuate the mentality of thinning is a process that can be outsourced in a patch, without the need for long -term commitments, exercise or changes in the diet. A “perfect body” culture is promoted regardless of cost, whether physical or psychological. In this sense, social networks are playing a key role, presenting these patches as an “easy” and “pain” of losing weight, not to mention the associated risks or realities behind these products. While the young women immerse themselves in this wave of weight loss, we are faced with a new form of social pressure that resurrects the cult of extreme thinness. The two thousand aesthetics, which glorified thinness, sneaks back into our screens and, with it, the return to the idea of ​​aesthetic pressure to be happy.

We have been using sweeteners that provide zero calories. Now we understand why they don’t always help lose weight

by

Sugar is one of the most daily foods and one on which food controversies do not scarce. Excessive sugar consumption can be linked to various problems, from the oral to diabetes. The artificial sweeteners that we sometimes use to reduce the consumption of conventional sugars can be healthier, but no less controversial. Less sugar, more hungry. A recent study He has found that some artificial sweeteners could be affecting the signals that manage our appetite at the brain level. The team responsible for the study observed that the Sucralosa had a less satiating effect than sucrose, conventional or table sugar. The Sucralosa. Sucralosa is a artificial sweetenera disaccharide or compound sugar such as the union of two simple sugars. Its sweetest capacity is up to 600 times higher than that of sucrose, but our body does not absorb it in the same way. This implies that this sweetener has no caloric contribution to our body. This could explain the observed phenomenon: our body would perceive the sweet taste and prepare for calorie ingestion. The body would simply be responding to the absence of energy received. 75 participants. In the study, 75 participants who worked as both of the experimental group and control group in two sessions separate days or weeks from each other took part. Participants, men and women, some with “healthy” weight, others overweight or obesity, consumed three drinks prepared in the experimental sessions to which they underwent. These preparations were a sweetened drink with sucralose, another with conventional sugar (sucrose), and another simple water. The order in which they assigned each drink was random. The team later studied the participants’ response to each drink. Before and after the test they carried out functional magnetic resonances, they took blood samples and asked the participants for their feeling of hunger. They observed that the sucralose increased appetite and activity in the hypothalamus and that it did it to a greater extent among the participants with obesity. The team also detected changes in how the hypothalamus communicated with other brain regions. The details of the study were published In an article In the magazine Nature Metabolism. Old acquaintances. The key can be in the hormones that our body produces when eating, hormones such as insulin and LPG-1 (Glucagon -like peptide 1). This last hormone is produced in the stomach when we eat and fulfills a double function: on the one hand warns the pancreas that we will need insulin to manage digerida glucose; and by transmits to our brain the message that we have fed and satiated. “The body uses these hormones to tell the brain that you have consumed calories, to reduce hunger,” Explain in a press release Kathleen Alanna Page, co -author of the study. “The Sucralosa did not have that effect, and the differences in hormonal responses to the sugar compared to sugar were even more pronounced in participants with obesity.” Much to investigate. According to the team itself, there are still some unknowns to solve in this context. One question, for example, is how this sweetener affects our brain activity in the long term. To do this, they explain, longitudinal studies will be necessary that also analyze the weight and food behaviors of the patients. Another issue to solve is how other factors affect, such as sex, this relationship. The team indicated that during the experiment, the brain activity of women showed greater variability than that of men, which implies the possibility of differences to study.
