A team of the University of Wisconsin, Madison, led by Dr Leah Whigham, discovered that the human adenovirus Ad-37 leads to obesity in chickens, marking the third virus to be linked to being overweight: two related viruses, Ad-36 and Ad-5, also lead to obesity in animals. What s more, Ad-36 has been connected with human obesity, which leads scientists to suspect that Ad-37 also may be connected. We know Ad-36, and now Ad-37, cause obesity in animals, said Dr Whigham, whose findings are published in the American Journal of Physiology. But we do not have cause-and-effect data in humans - you cannot ethically do the experiments for that kind of data: infect humans and see if they get fat. The idea that viruses can lead to obesity has been a controversial one among researchers, she admitted. And still, there is evidence that other factors may be at work.

To look cut, with great muscle definition, many people have the misconception that you need to hit the gym. That s the general belief: lift less weight and do more reps for definition. For bulk, lift heavier weight and do fewer reps. The idea that less weight tones muscles is wrong. Less weight and more reps builds endurance. For explosive power, do fewer reps with heavier weight. Just remember that to really increase strength the general consensus is that you have to work with at least 60 of your maximum lift the heaviest weight at which you can complete a singe repetition . Definition is not an issue when deciding how many reps to do and how much weight to lift. In reality, there is no such thing as lifting for definition.
