...have ever fought the battle of the bulge, then you are all too familiar with its key players: diet, exercise and your genes. The less you move (calories out) and the more you eat (calories in), the more fat you gain - an equation that may be heavily influenced by your particular genes. But scientists have long known that these three factors do not adequately explain every case of obesity, and now researchers are discovering increasingly convincing evidence of another important contributor to body weight, one that until recently has been almost completely ignored: the bacteria that live in your...
That diversity and its impact came into plain view when the researchers started experimenting with the rodents' diet. When one group of mice was fed a typical Western diet, high in fat and sugars, they tended to gain weight and grow more Firmicutes gut bacteria and fewer Bacteroidetes. In mice given a low-fat plant-based chow, the distribution of the two groups of bugs flipped and the animals remained lean. It's not clear whether the balance of gut bugs causes weight gain or is a result of it, but the findings suggest that a "gut profile" could potentially...
...important in controlling weight? As tempting as that conclusion might be, Wang and other health experts say that's not exactly what the new data show. The findings may say less about the role of exercise by itself than about the other variable in the weight equation - diet - and the interaction of the two. While exercise may not contribute directly to weight loss, it is critical for maintaining a healthy weight, since it helps calibrate the balance between energy taken in and energy burned off. "The data is too gross, and too general to assume that [exercise doesn't count...
...Behind Hatoyama's flip-flops is contradictory advice from top aides. Some are telling him to stick to fiscal austerity to mollify voters' fear of ever-larger deficits - a public concern that could hurt the DPJ's chances of winning a majority in crucial July 2010 elections for the Diet's Upper House to accompany its newly won majority in the Lower House. But come next July, the DPJ would be hurt a lot worse at the polls by higher unemployment than a higher deficit. What Japan needs today is fiscal stimulus that stresses the DPJ program to shift Japan...
...media loves epidemics. Every year the public is bombarded with headlines that leverage scary acronyms like SARS, MRSA, and H5N1 to capture our attention. This alphabet soup of pandemics is part and parcel of a perennial American diet consisting of hype and overreaction to illnesses with miniscule mortality rates...
