Technologies[modifier | modifier le code] TSRI Scientists Find Brain Hormone that Triggers Fat Burning Trending. LA JOLLA, CA – January 27, 2017 – Biologists at The Scripps Research Institute (TSRI) have identified a brain hormone that appears to trigger fat burning in the gut.

TSRI Scientists Find Brain Hormone that Triggers Fat Burning Trending

Their findings in animal models could have implications for future pharmaceutical development. “This was basic science that unlocked an interesting mystery,” said TSRI Assistant Professor Supriya Srinivasan, senior author of the new study, published today in the journal Nature Communications. Previous studies had shown that the neurotransmitter serotonin can drive fat loss. Four Common Myths About Exercise And Weight Loss. It’s that time of year when many are trying, and some are failing, to live up to their New Years' resolution of losing weight.

Four Common Myths About Exercise And Weight Loss

Many of these probably include resolutions to be more physically active in striving for this goal. But first, there are some common misconceptions about exercise and weight loss that need to be addressed. Exercise vs Diet. Which Diets Actually Work? Breast-Feeding the Microbiome. This is an edited excerpt from “I Contain Multitudes: The Microbes Within Us and a Grander View of Life,” which will be published on August 9th by Ecco, an imprint of HarperCollins Publishers.

Breast-Feeding the Microbiome

The Foods for Health Institute, at the University of California, Davis, has the appearance of a Tuscan villa, its terra-cotta-walled buildings overlooking a large vineyard and a garden that bursts with summer vegetables. Can your biome make you fat? Emily Pidgeon/TED Is there a correlation between your biome and your BMI?

Can your biome make you fat?

In her new book, Why Diets Make Us Fat, neuroscientist Sandra Aamodt sheds light on this tangled, cryptic relationship. There seems to be little doubt that the diet book of 2016 is Sandra Aamodt’s Why Diets Make Us Fat: The Unintended Consequences of Our Obsession with Weight Loss — it’s already been a cover story in the New York Times Sunday Review. But more significantly, Aamodt’s book lays waste to the diet-book field — and indeed the entire dieting field — with the radical assertion that it is, in fact, exactly the kind of weight loss generated by diets that prompt your body to regain the weight lost — whether you want to or not.

?articles. Changes in diet can cause gut microbes to produce acetate, which in turn stimulates insulin secretion and obesity in rodents, scientists show.


WIKIMEDIA, ORNLSeveral studies have linked changes in the gut microbiome to obesity, insulin resistance, and metabolic syndrome, but the details of the link have been unclear. Now, a team led by researchers at Yale University has uncovered one pathway leading from gut microbes to increased food intake and insulin secretion in rodents, pointing to potential therapeutic targets for obesity in humans. Will Pills Containing Fecal Matter Help Treat Obesity? Researchers at Massachusetts General Hospital in Boston are wondering whether gut bacteria from skinny people could help curb obesity in others.

Will Pills Containing Fecal Matter Help Treat Obesity?

A new clinical trial -- which is not yet open to participants -- will study the effects of gut microbes from lean, metabolically healthy donors on the bodies of people with obesity and/or insulin sensitivity. To get the microbes from one person to the other, scientists will freeze the feces from donors and case the material into pills, to be taken orally by the subjects. "Multiple lines of evidence suggest that gut microbiota play an important role in regulating human metabolism," the trial proposal explains. "Major study outcomes include change in weight, insulin sensitivity, and body composition. " Healthy guts burn more calories during sleepTrending. An unhealthy shift in your gut microbes might cause you to gain weight by changing how many calories you burn while you sleep, a new study with mice suggests.

"It's about a 16 percent change in resting metabolic rate, which is enormous," says Justin Grobe. "It would be 29 pounds of fat gained every year for an average human. " Image Credit: Yannig Van de Wouwer/Flickr When researchers used a drug to change the gut microbiome in mice, they saw a reduction in resting metabolic rate—the rate at which calories are burned while sleeping or resting. “Our research leads to the conclusion that it is probably bacteria (in the gut) that are responsible for the calories you burn while you are asleep,” says John Kirby, professor of microbiology and urology at the University of Iowa Carver College of Medicine and one of the authors of the study in eBiomedicine. Hibernating Bear Microbiome May Hold the Key to Combating Obesity. Gorging oneself on high-calorie food to pack on fat only to fall asleep for a few months and have it all melt away isn’t the latest diet fad (at least not yet), but it is a regular part of life for bears as they prepare to hibernate for the winter.

Hibernating Bear Microbiome May Hold the Key to Combating Obesity

Yet, despite the rapid weight gain, the animals somehow avoid the health consequences so often associated with obesity in humans. Poop Pills Investigated As Obesity Treatment. Could an exchange of poop from a slim person help an obese individual lose weight?

Poop Pills Investigated As Obesity Treatment

We could soon find out, as scientists in the U.S. are embarking on a clinical trial to find out whether so called “fecal microbiota transplantation” (FMT) can aid weight loss. Hearing the term “fecal transplant” may leave you with some tense glute muscles, and yes, the procedure can involve exactly what you’re thinking (a poop enema, in case you’re unimaginative). But this upcoming trial, led by Dr. Elaine Yu from Massachusetts General Hospital, will involve taking freeze-dried poop that’s been popped in a pill. We’ll let you decide which is the lesser of these two evils. There is, of course, method behind the madness. Fish oil turns fat-storage cells into fat-burning cells in mice, study finds. Fish oil has long been known to confer a wide range of health benefits, including boosting the cardiovascular system and potentially even treating the effects of schizophrenia.

Fish oil turns fat-storage cells into fat-burning cells in mice, study finds

Now a new study from Japan says it could also help people trying to lose weight. Researchers from Kyoto University found that mice fed on fatty food and fish oil gained considerably less weight and fat than mice that consumed fatty food alone. The findings suggest that fish oil is able to transform fat-storage cells into fat-burning cells – and if the same process occurs in humans, fish oil could help us reduce weight gain, especially as we age, when our fat-burning cells are in lesser supply. ?articles. “This paper, which had nicely controlled conditions, demonstrated that type of fat is really important for shaping microbial communities and their functional dynamics, which in turn impact our health,” said Vanessa Leone, a postdoc studying host-microbe interactions at the University of Chicago who was not involved in the study.

“It had been previously shown that switching to a high-fat diet markedly and rapidly alters the gut microbiota, but this study goes farther to show that feeding different types of fat result in very different composition of gut microbiota,” Sean Davies, a professor of pharmacology at Vanderbilt University in Nashville, Tennessee, wrote in an email to The Scientist. Davies, too, was not involved in the research. A team led by investigators at the University of Gothenburg in Sweden fed mice diets with the same total number of calories, but some mice received nearly all their fat intake from fish oil, while others received large amounts of lard. Thunder God Vine Extract Makes Obese Mice Rapidly Shed The Pounds. A Drug that can Beat Obesity?Trending. Obesity has long been a global epidemic with an estimated 2.8 million people dying each year from associated complications. In addition to watching one’s diet and exercise, advancements in science have created opportunities to treat obesity with medicine.

However, none has ever been shown to be effective. From bariatric surgery to the latest diet super-pill, obesity remains a global health issue. Research efforts to treat obesity have recently focused on the hormone leptin, discovered 20 years ago to be associated with feeling full after a meal. In healthy individuals, leptin has the ability to suppress food intake and reduce body mass. New Molecule That Mimics Exercise Could Help Treat Obesity and Diabetes.

In a dream world, we’d be able to lose weight without all the sweaty, hard work of exercising. Researchers who have developed a molecule that mimics exercise suggest this may no longer just be a far-fetched fantasy. The molecule does this by first inhibiting the function of ATIC, a cellular enzyme involved in metabolism. This inhibition causes another molecule called ZMP to accumulate in the cells. The buildup of ZMP tricks the cell into acting as if they are running out of energy. AMPK, the cell's central energy sensor, is activated, causing the cells to compensate for the supposed lack of energy by increasing their glucose uptake and metabolism. The Verdict is In: Feel-Good Exercise Hormone Irisin Is Real. Scientists in the US have found that a feel-good exercise hormone called irisin does indeed exist in humans, putting to bed long-disputed claims that it is a myth. The research team, led by Bruce Spiegelman from the Dana-Farber Cancer Institute, used mass spectrometry to look for irisin in blood samples of individuals after exercise, finding that these people had released the exercise hormone from their body, which activates fat cells to increase energy turn over.

The research was published today in the journal Cell Metabolism. “Concentrations are present in sedentary individuals and are significantly increased in individuals undergoing aerobic interval training,” the researchers said in the paper. “We therefore also confirm our earlier report of irisin being regulated by endurance exercise in humans.” Beige Fat Implants Increase Body Heat, Reduce Weight Gain. Fat does a better job of turning up the metabolic heat, and lessening the risks associated with obesity and diabetes, if it has a favorable balance of energy-storing fat and energy-burning fat.
