When What You Eat Effects Weight Gain

New research shows that eating  when your body’s metabolism doesn’t want you to plays a role in weight gain. These findings are to be published in the Proceedings of the National Academy of Sciences.

The study specifically focused on how nighttime light affects when we desire to eat, which then in turn affects our body  mass index. “Light at night is an environmental factor that may be contributing to the obesity epidemic in ways that people don’t expect,” said Randy Nelson, co-author of the study and professor of neuroscience and psychology at Ohio State. “Societal obesity is correlated with a number of factors including the extent of light exposure at night.” The scientists studied the effects of night time light by observing its affects on mice. “Although there were no differences in activity levels or daily consumption of food, the mice that lived with light at night were getting fatter than the others,” said Laura Fonken, lead author of the study and a doctoral student in neuroscience at Ohio State University. “Something about light at night was making the mice in our study want to eat at the wrong times to properly metabolize their food,” said Nelson. “When we restricted their food intake to times when they would normally eat, we didn’t see the weight gain,” Fonken said. “This further adds to the evidence that the timing of eating is critical to weight gain.” If these same results prove valid in humans, this study indicates that late night eating, as well as chronic exposure to night time lighting may contribute to obesity.

Making Biodiesel Now Faster and Greener

Biodiesel proponents are buzzing with excitement about the news of a greener and faster way to convert used vegitable oil into biodiesel. Two chemists from Brown University have figured out a way to convert used vegitable oil into biodiesel in 20 minutes, as compared to 2 hours. In addition to the faster conversion time the researchers also discovered how to complete the entire process without using toxic chemicals.

The research was published this week in the journal Organic & Biomolecular Chemistry.With the future of biodiesel looking to play a considerable role in the future fuel supply, scientists are continually looking for methods that do not compromise the environment in order to obtain greater efficiencies. “We wanted to develop an environmentally benign and technically simple way to convert waste vegetable oil into biodiesel,” said Jason Sello, assistant professor of chemistry. “The production of energy at the expense of the environment is untenable and should be avoided at all costs.” The scientists were able to replace the hazardous chemicals with the more benign catalysts bismuth triflate and scandium triflate, which are chemically stable, cheap and of limited toxicity. “While we have not yet proven the viability of our approach on an industrial scale,” Sello said, “we have identified very promising catalysts and reaction conditions that could, in principle, be used for large-scale conversion of waste vegetable oil into biodiesel in an environmentally sensitive manner.”

Citrus Juice In Green Tea: 80% More Antioxidants

Scientists are saying that the ever popular and highly regarded green tea can be made even more healthful by adding citrus juice.

A study led by scientists at Purdue University comparing the effect of various beverage additives on the naturally occurring antioxidants found in tea called catechins, has revealed that by adding lemon, orange, lime or any other citrus juice to green tea there will be an 80% increase in the amount of antioxidants that can be absorbed by the body. “If you want more out of your green tea, add some citrus juice to your cup after brewing or pick a ready-to-drink product formulated with ascorbic acid,” said Mario Ferruzzi, assistant professor of food science at Purdue University and the study’s lead author. The researchers explained that the antioxidants are better preserved in an acidic, vitamin c rich environment. The un-acidic state of the intestines eliminate many of the antioxidants before they can be absorbed by the body. “Off the bat you are eliminating a large majority of the catechins from plain green tea,” Ferruzzi said. “We have to address this fact if we want to improve bodily absorption.” This is good news for an already healthy drink. This adds to the large body of research that has been growing over the years showing the many health benefits of green.

Too Little Sleep Inhibits Burning Fat

One of the reasons so many people struggle to burn fat when working out is due to not getting enough sleep.

New research from the University of Chicago’s General Clinical Resource Center has just shown that when people are sleep deprived they may still loose the wight from dieting, but more of the lost weight is muscle, instead of fat. “If your goal is to lose fat, skipping sleep is like poking sticks in your bicycle wheels,” said study director Plamen Penev, MD, PhD, of the University of Chicago. “Cutting back on sleep, a behavior that is ubiquitous in modern society, appears to compromise efforts to lose fat through dieting. In our study it reduced fat loss by 55 percent.” The human body produces more of a hormone called ghrelin when it lacks sleep. Higher ghrelin levels are known to “reduce energy expenditure, stimulate hunger and food intake, promote retention of fat, and increase hepatic glucose production to support the availability of fuel to glucose dependent tissues,” the authors note. “In our experiment, sleep restriction was accompanied by a similar pattern of increased hunger and … reduced oxidation of fat.” “For the first time, we have evidence that the amount of sleep makes a big difference on the results of dietary interventions. One should not ignore the way they sleep when going on a diet. Obtaining adequate sleep may enhance the beneficial effects of a diet. Not getting enough sleep could defeat the desired effects,” said Penev.
