...simple terms, body weight is a reflection of the balance between two variables: the calories a body takes in and the calories it burns off. As far as the average U.S. teen is concerned, the study suggests, the culprit behind weight gain is not a decrease in exercise but an increase in consumption. Of course, that doesn't mean teens are getting adequate exercise: Wang analyzed data from nearly 16,000 high school students between the ages of 15 and 18, who took part in the Centers for Disease Control and Prevention's longitudinal Youth Risk Behavior Surveillance Survey, about...
...does this mean that exercise isn't 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...
Rankin points out that even small changes in a person's energy balance can have a significant effect on weight. Studies have shown that eating just 10 to 20 extra calories per day - that's one peanut M&M or one tortilla chip - that don't get burned through activity can result in a 2-lb. gain on average over the course of a year. "But none of the methods we have now are accurate enough to pick that up," says Rankin...
...fresh 271-lb. (123 kg) bluefin snared off Oma, a small Japanese town. Bluefin can live for decades, growing more than 10 ft. (3 m) long, weighing up to 1,500 lb. (680 kg), and with enough muscle to propel them at 40 m.p.h. (65 km/h). Throwing his weight into the fish as he makes a cut, Morishima is philosophical. "Some think it's endangered, and I understand their position, but what can you do by worrying about it?" he asks. He'd like all his bluefin to come from Japan, but if there are none on any given...
...naturalistic pantheism, there are various belief systems that deify the natural world. But should a fervent belief in the need to fight climate change be given the same legal protection as an actual religion? A London judge said yes, ruling this week that environmentalism should carry the same legal weight as religion under Britain's employment laws...
