More than 20 million Britons, 1 in every 3 alive (among them King George VI), tuned in to their radios in 1951 when Randolph Turpin took on Sugar Ray Robinson for the middleweight crown of the world. This was doubly surprising, insofar as the mixed-race Englishman was boxing for a country where, just four years earlier, blacks - even if British-born - were not allowed to compete for the national championship. When Turpin pulled off a remarkable upset against the highly favored American - only Robinson's second loss in 135 fights - he seemed more than ever an emblem...
...debate about what is now known as the Warburg effect - whether it is the primary cause of cancer or a mere metabolic side effect - is irrelevant. What they believe is that it can be therapeutically exploited. The theory is simple: If most aggressive cancers rely on the fermentation of sugar for growing and dividing, then take away the sugar and they should stop spreading. Meanwhile, normal body and brain cells should be able to handle the sugar starvation; they can switch to generating energy from fatty molecules called ketone bodies - the body's main source of energy...
...that's what a new study published in the Sept. 18 issue of the journal Annals of Internal Medicine found. But it also found that not all exercise is created equal and that the combination of aerobic exercise and weight training is significantly better for controlling blood sugar than either alone...
Overall, researchers saw improvements in blood-sugar control in all the patients who worked out. Compared with controls, patients in the aerobic group had a reduction of .51% in their hemoglobin A1C values - a test that measures blood-sugar control over the previous two to three months (lower is better). The weight-training group had a .38% reduction compared with controls. But the combined exercise group showed further improvements: in those patients, the A1C values went down an additional .46% over the aerobic group, and .59% over the weight-training group. Compared to controls, the combo exercisers had a nearly...
...benefits of a 1% drop aren't small, and they go beyond blood-sugar control: That reduction translates to a 15% to 20% decrease in heart attack and stroke risk and a 25% to 40% lower risk of diabetes-related eye or kidney disease. "To envision the importance of exercise, imagine an inexpensive pill that could decrease the hemoglobin A1C value by 1 percentage point," write Dr. William Kraus of Duke University Medical Center and Dr. Benjamin Levine of the University of Texas Southwestern Medical Center at Dallas, in an accompanying editorial. "Diabetes experts would be quick to incorporate this...
