Drinking coffee could activate the body's fat-fighting defenses, a discovery that could have potential implications in the battle against obesity and diabetes.In a study published Monday, researchers at the University of Nottingham said that coffee may help stimulate our brown fat reserves, also known as brown adipose tissue, which play a key role in how quickly we can burn calories.There are two forms of fat cells, brown cells and white cells, and each plays a different role in our metabolism.While brown cells help generate heat, white cells are responsible for the storage of fat -- or, energy -- ready for release as needed. Levels of brown fat are known to be high in children but recent findings on the presence of brown fat in adults has restored hope to use them as targets to treat obesity."Brown fat works in a different way to other fat in your body and produces heat by burning sugar and fat, often in response to cold, said professor Michael Symonds, from the School of Medicine at the University of Nottingham, who co-directed the study."Increasing its activity improves blood sugar control as well as improving blood lipid levels and the extra calories burnt help with weight loss. However, until now, no one has found an acceptable way to stimulate its activity in humans."The scientists started by testing out coffee on stem cells to see if it would stimulate brown fat. Once they found the right dose, they moved on to humans to see if the results were similar.The team used a thermal imaging technique on four men and five women to trace the brown fat reserves and see how it produced heat."From our previous work, we knew that brown fat is mainly located in the neck region, so we were able to image someone straight after they had a drink to see if the brown fat got hotter," Symonds said.So will drinking a cup of coffee help you lose weight, as well as get out of bed?The study only involved nine people and the research is still at a very early stage. Scientists say they still need to determine what it is exactly about coffee that busts fat."The results were positive and we now need to ascertain that caffeine as one of the ingredients in the coffee is acting as the stimulus or if there's another component helping with the activation of brown fat," Symonds said."Once we have confirmed which component is responsible for this, it could potentially be used as part of a weight-management regime or as part of glucose regulation program to help prevent diabetes." 2507

Dog's aren't just our best friends, they're also good for our health, new research suggests.A study published Friday in the journal Mayo Clinic Proceedings says that owning a pet, especially a dog, may help maintain a healthy heart -- in case you needed any more reason to head to your local animal shelter.The study began in 2013 and 2014, when researchers gathered health and socioeconomic information on over 2,000 people in Brno, Czech Republic, and scheduled follow-up evaluations for every five years until 2030.The latest was this year, in 2019, when researchers again looked at about 2,000 people with no history of heart disease. They scored the participants on the American Heart Association's list of seven ideal health behaviors and factors, also known as "Life's Simple 7": body mass index, diet, physical activity, smoking status, blood pressure, blood glucose and total cholesterol.The researchers compared the cardiovascular health scores of pet owners with those of petless people. In general, people who owned a pet were more physically active than those who did not, with healthier diets and blood sugar levels.But then they compared dog owners with everyone else and found that no matter their age, sex or education level, they benefited the most in terms of cardiovascular health.Take that, cat people.The findings are consistent with research that has shown that dog ownership leads to more physical activity. Meanwhile, pet ownership in general reduces stress, betters our self-esteem and makes us more social.Francisco Lopez-Jimenez, one of the lead researchers on the team, said what makes this study so significant is that it showed the benefits of having a dog go beyond just increased physical activity. The study included many factors that determined the health of the heart and arteries, like showing that dog-owners tend to also have a healthier diet than other pet-owners -- thus contributing to a better cardiovascular health.It's "putting everything together and not just focused on a single factor," he told CNN.But he also pointed out that the results may be skewed, simply because so many people own dogs. Of the 42 percent of subjects that owned any type of pet, 24 percent were owned dogs. 2240
