    Natural Metabolite Might Reset Aging Biological Clocks

    As we age, our biological clocks wind down – but why? Dr. Gad Asher, who studies circadian clocks – genetic mechanisms that keep us in tune with cycles of day and night – has identified a link between the clocks and a group of metabolites called polyamines. Found in many foods, polyamines could fight aging – as they did in Dr. Asher's mice.

    Time to Eat

    Dr. Gad Asher and colleagues found that mitochondria (which give cells power) are regulated by the body's circadian clocks; in fact, mice who ate only when active had 50% lower liver lipids. The findings help explain why people who eat out of phase with their circadian clocks are more likely to develop obesity, diabetes, and metabolic syndrome.

    Time is of the Essence

    Many of our biological processes follow a 24-hour ""body clock."" Triglyceride (TAG) levels do as well. Strangely, when no biological clock is present, TAG levels in mice still fluctuate. Dr. Gad Asher and colleagues changed when the mice ate – and cut their TAG levels in half. Could merely changing meal time treat TAG-related diseases?

    Artificial Sweeteners May Lead to Diabetes

    <em>USA Today</em> covers the recent Weizmann Institute research revealing that artificial sweeteners may cause weight gain and diabetes. As it reports, the study shows that ""differences in gut microbes may explain why some people can handle artificial sweeteners just fine while in an unknown percentage of others the sweeteners lead to diabetes.""

    Why Yo-Yo Dieters Often Can't Keep the Weight Off

    People all over the world repeatedly go through the long, frustrating, defeating struggle known as ""yo-yo dieting"": they lose weight, only to gain it again, over and over (and over). Now, new research from Dr. Eran Elinav and Prof. Eran Segal shows why: the gut microbiome keeps resetting the body to gain weight.

    Study Gives Insight Why Females Are Prone to Eating Disorders

    As <em>Haaretz</em> reports, new research by Prof. Alon Chen shows that a ""brain receptor regulates stress responses differently in male and female mice,"" and the way females eat is affected. In fact, female mice were generally impacted more severely by stress. The stress-regulating protein is located in the hypothalamus, which also plays a role in metabolism.

    To Help Treat And Prevent Obesity, Your Body's Immune System May Be Key

    The Weizmann Institute's renowned Prof. Yair Reisner has discovered that the lack of a particular type of immune cell leads to obesity in mice. As reported on Medical Daily, Prof. Reisner indicates that this is the first time researchers have been able to show a connection between fat cells and inflammation in animals that are on a regular diet.

    Yale Participates in International Metabolic Research Alliance

    Scientists from Yale University, the Jackson Laboratory, the University of Connecticut, and the Weizmann Institute of Science have come together to form the Metabolic Research Alliance. As the Yale Daily News announces, the global group will study metabolic diseases, such as diabetes and obesity.

    Bespoke Diets Based on Gut Microbes Could Help Beat Disease and Obesity

    Dr. Eran Elinav and Prof. Eran Segal's Personalized Nutrition Project aims to change how we eat, tailoring food intake to our bodies' own needs. <em>The Guardian</em> reports that, at a conference, the two are explaining how they've ""created bespoke diets using a computer algorithm that learns how individual bodies respond to different foods.""

    Diet Soda May Alter Our Gut Microbes and Raise the Risk of Diabetes

    On NPR's <em>All Things Considered</em>, Allison Aubrey covers the Weizmann Institute's recent study on artificial sweeteners. Scientist Dr. Eran Elinav tells her that people in the study had ""significant disturbances in their blood glucose even after short-term exposure to artificial sweeteners"" – however, he and other scientists NPR interviewed stressed the need for further research.
